Chip, optical fiber and optical cable are the hardware foundation of today’s information-based, intelligent and networked society, and electronic-grade quartz sand with purity of 99.999% is the basic raw material for manufacturing chip, optical fiber and optical cable. For a long time, China’s electronic grade quartz sand has relied on imports. Breaking the "ceiling" of 80% purity of domestic mainstream quartz sand, breaking foreign technical barriers and solving the "stuck neck" problem … Xie Dachun, technical director of Jiangsu Xinyiding Shi Ying Science and Technology Co., Ltd., did not stop, still buried himself in the laboratory all day, holding his sleeves, and continued to seek breakthroughs in quartz sand raw materials whose purity has reached the world’s top level.

"Ingenuity is the determination to break through and the patience to study."

On the afternoon of April 3rd, in the roasting workshop of Jiangsu Xinyiding Shi Ying Science and Technology Co., Ltd. in Shuyang County, Suqian City, a "big guy" connected with a huge water tank was rising with white steam, which was a "unique weapon" for enterprises to purify quartz sand. This reformed equipment led by Xie Dachun won the national invention patent.

In the purification process of quartz sand, many impurities are micron-sized and need to be treated by cold explosion. That is, using the principle of thermal expansion and cold contraction, high-temperature quartz sand is put into cold water to burst, so as to achieve the effect of separating impurities. However, as soon as the high-temperature quartz sand enters the water, the cold water becomes boiling water, and the effect of cold explosion is greatly reduced. Many domestic technical teams are stuck in the "cold explosion" level.

"In those years, I walked repeatedly in my mind to do simulation tests, and finally I had this machine." Xie Dachun said that a few years ago, he happened to pass by a popcorn stand. At that time, the sound of popcorn startled him, but it was this "bang" that reminded him of the solution of "cold explosion" technology from the production principle of popcorn. Then, he immediately rushed back to the company and took his colleagues to discuss. Finally, he invented the current dynamic roasting and cold explosion technology: in a quartz tube with a constant temperature of 930℃, Shi Ying blocks were continuously put in, and during the falling process, they were evenly heated to complete the cold explosion.

In the following years, Xie Dachun and the company constantly improved their equipment in the process of updating their production technology, and only the equipment for producing electronic-grade quartz sand was updated for more than ten times, finally achieving self-sufficiency of electronic-grade quartz sand.

The reporter noticed that there are not many operators in such an important roasting workshop, and a large number of operation links have been replaced by hanging rails and electric cranes. Workers only need to control them remotely. "This is also a bitter credit! In the traditional process, there is a great demand for workers in the roasting workshop, and at the same time, because of the high temperature, workers are easily burned if they are improperly operated, so the turnover rate is very high. " Wang Wei, the production director of the company, told the reporter that at that time, when the company was troubled by this "industry problem", Xie Dachun took the task without saying anything.

In the next three months, Xie Dachun "closed the door" in the workshop and kept researching and experimenting all day. There were more than 500 drawings drawn alone. After repeated experiments for more than 260 times, we finally found such a "machine substitution" method, which solved the production problem satisfactorily and thoroughly. Now this method has been widely used in the whole industry.

"I am a farmer, and I failed in the college entrance examination. Even when I entered the business, I only had some electrician foundation, so as long as I am willing to study, I can always find a solution to the problem." Xie Dachun told reporters that he is a veritable "soil expert". All scientific research achievements and invention patents were explored in workshops and laboratories, and this experience also reflected his understanding of "ingenuity": the determination to break through and the patience to study.

"Social terrorism" experts break the technical blockade

Xie Dachun has a dazzling "report card": in the past 30 years, he has won more than 20 national, provincial and municipal scientific and technological innovation achievement awards and science and technology awards, and has more than 100 invention patents and utility model patents, among which five scientific and technological achievements such as "domestic preparation technology of electronic quartz sand" have filled the domestic gap and reached the international advanced level.

Due to the particularity of the industry, electronic quartz sand is mainly used in high-tech fields such as semiconductors, electrical and electronics, aerospace, national defense and military industry. "For a long time, the purification technology of electronic grade quartz sand has been firmly stuck in foreign countries. Because of technical barriers, the previous domestic quartz sand products can only be used in some low-end products such as halogen lamps, and they can’t touch the threshold of high-end market at all." Director Wang Wei told the reporter that even the leading domestic companies, with the same foreign equipment, have only got the "admission ticket" to the high-end market, and for a long time, 80% of the purity of the domestic mainstream quartz sand products industry has been "ceiling".

Due to the high cost of R&D, many manufacturers have no choice but to give up and import from abroad at a high price of nearly 100 times after entering a "dead end" again and again, but Xie Dachun has been insisting.

"Increase 80% to 99%, and then increase the’ 9′ after the decimal point of 99.9% to three, five or even more, and each step will take three years or more to try and make mistakes." Liang Haidong, Xie Dachun’s apprentice, said that for this goal, Xie Dachun has become the most "social fear" person in the company: in the past 20 years, he has been eating and living in the laboratory, and rarely has any work-related communication with outsiders.

"Striving for Excellence and pursuing the ultimate" is a feature that Xie Dachun once exhorted and taught Liang Haidong more than once, and it is also the best embodiment of Xie Dachun’s "artisan spirit". With the ingenuity of this craftsman, he has endured loneliness for more than 20 years, and has successfully developed a number of high-efficiency, energy-saving and environmentally-friendly mechanical and electrical equipment. More than 20 new products have been widely used in high-tech fields such as semiconductor integrated circuits, aerospace satellite testing, and fiber-optic chip manufacturing for national defense and military industry.

In 2021, Jiangsu Xinyiding Company solved the purification problem of electronic grade quartz sand and became the only enterprise in China that can improve the purity of quartz sand to "six 9s".

Over the years, under his example, more than 300 people have grown into the technical backbone of Shi Ying products manufacturing industry and become a new force to promote technological innovation of enterprises in the industry.

The industrial craftsman "Jin Gangzuan" brought in income of nearly 3 billion yuan.

Replace the old baking oven with a new intelligent baking oven with automatic temperature control, popularize the use of frequency conversion governor for automatic speed regulation, and automatically control the continuous melting furnace with laser controller …

During the interview, Chen Qiong, general manager of Jiangsu Xinyiding Shi Ying Science and Technology Co., Ltd., pointed to the equipment in various production workshops from time to time and proudly told reporters that these were the results of the company’s independent research and development or improvement, most of which were attributed to Xie Dachun.

Ingenuity brings prosperity to all industries. "Every industrial craftsman is a’ Jin Gangzuan’ that will never change in the high-quality development of enterprises!" Chen Qiong sincerely said that thanks to Xie Dachun’s continuous technological innovation for many years, numerous innovations have brought direct or indirect benefits of nearly 3 billion yuan to enterprises, and its social and economic benefits are obvious to all.

In the development layout of enterprises in recent years, Jiangsu Xinyiding Shi Ying Science and Technology Co., Ltd. has invested heavily in its own scientific and technological innovation and project research and development, and successively acquired a number of surrounding enterprises. On the basis of lengthening the original industrial chain, it opened a separate research and development workshop, and appointed Xie Dachun to continue to set up a technology research and development team to strengthen the scientific research strength of enterprises and enhance their core competitiveness.

"Use new products and innovative technologies to save enterprises and reduce the burden on society." In Xie Dachun’s view, this is not only a technician’s obligation to society, but also an inevitable requirement for the development of modern industrial system. At this year’s National People’s Congress, new quality productivity and craftsman spirit have become hot topics together, and the close relationship between them is self-evident. He said that at present, it is an excellent stage for high-skilled talents to display their fists and feet, and he will also strive to lead his colleagues to forge a hard-working style of Excellence and diligent study, and strive to move closer to "knowledge-based, skilled and innovative" craftsmen in big countries.

Tang DM

Subsidized selling price: 239,900-329,900 yuan.

Pure electric cruising range: 80km/100km

● Model introduction

BYD’s new generation Tang DM is a model based on BYD BLP large luxury platform, which was officially launched in June this year. In fact, for Tang DM, everyone is familiar with it. Since the previous generation, its good acceleration ability has attracted many people’s attention, and this new generation of Tang DM not only inherits the excellent acceleration performance before, but also has a more beautiful face.

The appearance of the new generation of Tang DM can be said to have changed a lot from the old models. The car adopts the latest Dragon Face design language of the family, which makes the whole car look more spiritual. The large-mouth mesh makes the visual impact stronger, and at the same time, it is connected with the headlight group to highlight the overall sense. The whole system comes standard with LED headlights, which are sharp in style. The three LED headlights inside are very refreshing, and the visual effect of the running turn signal is also good. In addition to the lowest four-wheel drive Zhilian Chuangyue model, the whole system comes standard with adaptive far and near light. Behind the driver’s side is a gasoline filler. This 2.0T engine can meet the demand of 92 # gasoline without picking oil, and behind the co-pilot’s side is a charging interface. Officially, it takes five hours to fully charge the battery. Compared with the front of the car, the tail style looks more solid and not as exaggerated as the front of the car, but the suspended roof and the penetrating three-dimensional taillights enhance the design sense of the tail and look quite fashionable.

From the outside to the inside of the car, we can see that the overall design of the interior is very simple, and we can’t see too many physical buttons. The material on the center console feels fine, but it is not soft enough, and it has a general sense of advanced. However, the large rotatable multimedia screen in the center attracts people’s attention. At the same time, the functionality of this large screen is good, and the fluency of use is satisfactory. The functions such as air conditioning, sound and multimedia can be operated through this screen. In addition, it can also be used. Although the full LCD instrument is not a new product in this level of China brand SUV at present, the full LCD instrument on Tang DM is quite reasonable in layout, not messy, functional and convenient to look at. The steering wheel is comfortable to hold, and the size is appropriate. The shift lever has not adopted a new design, and there are physical buttons such as air conditioning and ESC off around it, which can improve the convenience of use accordingly.

In terms of space, Tang DM’s performance is not bad, and there will be no sense of oppression when sitting in it. For seven-seat vehicles, even if the rear seat is adjusted to the front, the leg space of the rear passengers will not be crowded, and the back of the rear seat can be adjusted back and forth. The headrest is arranged in the center, and the seat cushion is flat, and the floor projection is small, so the comfort of the passengers is still guaranteed. It’s no problem to take an adult of 170cm in the third row seat, especially if the second row seat is a little forward, then the third row passengers can be more comfortable.

The performance of the trunk is good and smooth. When the third row seat of the 7-seat model is activated, after putting a 24-inch suitcase, you can also put a schoolbag. When the third row seat is put away, the trunk is quite large, and the second row seat can be put down at a ratio of 4/6 to improve the space flexibility.

In terms of power, Tang DM, like the old models, is equipped with a 2.0T engine with a maximum power of 205 HP (151 kW) and a maximum torque of 320 Nm. However, in terms of electricity, the new car has been upgraded to some extent. First, a BSG motor has been added. By optimizing the electronic control management system, the new car has better economic capacity than the old model. In addition, with a front-axle motor with a maximum power of 110kW (150 HP) and a maximum torque of 250 Nm and a rear-axle motor with a maximum power of 180kW (245 HP) and a maximum torque of 380 Nm, the whole hybrid system can explode with a maximum torque of 950 Nm. In terms of battery configuration, Tang DM provides 80 and 100 configurations, of which the total energy of the power battery of Tang DM 80 model is 20kWh and the cruising range of pure electricity is 80 kilometers; The total energy of the power battery of the DM 100 model of Tang Dynasty is 24kWh, and the cruising range of pure electricity is 100 kilometers. In terms of charging time, both of them can be fully charged in 4-5 hours. The ATS all-terrain system of the car can provide five driving modes, namely energy saving, sports, sand, mud and snow.

Judging from car home’s measured acceleration performance of Tang DM, the acceleration ability of 0-100km/h in 4.7 seconds can be said to be very conspicuous, and it is completely driven by motor at the beginning, and the whole acceleration process has a strong sense of pushing back. In the pure electric mode, when the power is sufficient, the engine will not start even if the accelerator is stepped on deeply, and the whole driving process is very quiet, and the vehicle is completely driven by pure electricity. In hybrid mode, it will definitely not be as quiet as pure electric mode, and the engine will bring some vibration and noise, but the overall noise control is good and will not give you obvious feelings. There is no virtual position in the steering, and the accuracy is quite high. The suspension supports the car body in place, and the roll is not big when the car is cornered at a faster speed.

● Recommended models

There are 7 models of BYD Tang DM, of which the full-time four-wheel drive Zhilian Chuangshi Edition sells for more than 300,000 yuan after subsidy, which is out of our recommended range. Of the remaining 6 models, 4 are pure electric vehicles with a battery life of 80km, and the remaining 2 are pure electric vehicles with a battery life of 100km. Among the models with a battery life of 80km, only the full-time four-wheel drive Zhilian Chuangxiang model with a subsidized price of 254,900 is a 5-seat version, because if you want to buy a model with a battery life of 80km and want to choose a 5-seat version, you can only buy this model. Among the 7-seat models with a pure electric battery life of 80km, the most recommended model is the 259,900 full-time four-wheel drive Zhilian Chuangxiang model. Compared with the full-time four-wheel drive Zhilian Chuangrui model, the car is 10,000 higher, and it is worthwhile to add 360-degree panoramic images, 12.3-inch full LCD instruments, front seat heating/ventilation, and interior atmosphere lights. If you want to choose a five-seat version with a pure electric cruising range of 100km, you can only choose a full-time four-wheel drive Zhilian collar model with a subsidized price of 274,900. If you choose a 7-seat version with a pure battery life of 100km, it is recommended to create a full-time four-wheel drive Zhilian collar.

Summary:

As a medium-sized plug-in SUV that entered the new energy market earlier, the change of the new generation of Tang DM is quite thorough, and both the appearance design and the power electronic control system are satisfactory. At the same time, in terms of configuration and practicality, the car is also in place and can meet the needs of most users.

WEY P8

Subsidized selling price: 244,800-279,800 yuan.

Pure electric cruising range: 50km

● Model introduction

WEY P8 is the first plug-in hybrid four-wheel drive SUV launched by WEY, a brand of Great Wall, which was officially launched in April this year. The new car is built on the new WEY Pi4 platform, and the overall design style is basically consistent with VV7, which is quite dynamic. Let’s take a closer look.

WEY P8 continues the design language of VV7 in appearance, but it has been adjusted in details. The exaggerated integral net looks more exaggerated than VV7. The driver’s left front fender is equipped with a charging interface, which takes up to 4 hours to fully charge the battery. The Pi4 logo behind the interface represents WEY’s plug-in four-wheel drive platform. There is little difference between the design of the car side and the rear of the car and WEY VV7, and the design of the rear of the car is still very dynamic. Although P8 is a hybrid car, it is also equipped with bilateral exhaust, which looks very handsome. The rear of the car on the co-pilot side is the fuel tank cover, so it is enough to fill with 92 # gasoline.

The interior design is basically the same as VV7, but because of its special status as a new energy source, some specific settings have been made on the function buttons. Sitting in the car, whether it is above or below the center console, all of them are wrapped in soft materials, which feels very delicate. The full LCD instrument panel is familiar to everyone. The functions are clearly displayed, the layout is clear, and it is quite convenient to use. By the way, the tachometer originally on VV7 has been converted into a power meter. The multimedia screen on the center console can display the schematic diagram of power output, and at the same time, through this screen, you can set the vehicle reservation charging, low-speed virtual engine sound and energy recovery. A knob is set below the center console, which can switch between AUTO mode, EV mode, SAVE mode and SPORT mode. At the same time, after pressing the middle AWD, three all-terrain modes can be selected: snow, mud and sand.

The performance of WEY P8 in space is not ideal, because of the overall shape, the head space of the rear passengers is somewhat depressed. Fortunately, the comfort of the front and rear seats is good, the cushion is quite thick, and the wrapping and support of the backrest are satisfactory. The space of the trunk is somewhat unsatisfactory. Originally, due to the modeling reasons, the volume of the trunk will be affected. In addition, the battery pack is inside the trunk, which further reduces its volume. Fortunately, the rear seats can be folded 4/6, which can expand the storage capacity.

In terms of power, WEY P8 is equipped with an engine with a maximum power of 340 HP (250 kW) and a maximum torque of 542 Nm. This engine is exactly the same as the one on VV7. In addition, it is equipped with a 15 kW BSG auxiliary belt starter motor and an 85 kW TM drive motor. TM drive motor can drive the rear wheels independently, thus realizing electric four-wheel drive. The car has a combined maximum power of 340 HP (250 kW) and a maximum torque of 542 Nm. The power system is matched with the 6-speed wet gearbox of Gertrak.

The ride comfort of P8 is better than that of VV7 at the start, and the dynamic response is much more positive during driving. With the accelerator pedal, the sense of acceleration is still obvious. When the speed exceeds 100km/h, the power will not feel any attenuation. On the high-speed test ring track, with four people on board, P8 can still run 239km/h, while the flagship model, car home actually measured the acceleration of 0-100km/h for 6.25 seconds. In EV mode, lightly stepping on the accelerator pedal can only rely on the motor to drive the vehicle. If you step on the accelerator pedal suddenly, the engine will intervene. When the engine intervenes, the driver can feel it, but the sense of suddenness is not strong.

● Recommended models

There are three models in WEY P8, and the subsidized price is 259,800-279,800 yuan, all of which are in line with our recommended price range. The recommended model is the exclusive model with a price of 269,800 yuan, which belongs to the middle model of WEY P8, and is 10,000 yuan more expensive than the exclusive model. However, it is worthwhile to have additional configurations such as parallel assistance, lane departure warning, lane keeping assistance, fatigue driving reminder, reversing side warning, electric trunk and electric trunk memory.

● Summary:

In appearance, P8 continues the exaggerated design of VV7, and its good comfort is still one of its highlights. At the same time, this car has strong driving power and excellent ride comfort, which is a big selling point. However, the space in the trunk is not ideal, and the space in the back row is also average. If the WEY brand new energy vehicle can change these shortcomings in the future, its market potential will be even greater.

Chang ‘an CS75 PHEV

Subsidized selling price: 165,800-196,800 yuan.

Pure electric cruising range: 60km

● Model introduction

Changan CS75 PHEV is a compact SUV, so the price will be cheaper than the above two models. The car was officially launched in August 2018. The exterior design of the new car is consistent with the fuel version, and the interior materials are good. It is equipped with a battery pack with a capacity of 12.96kWh, which can reach 60km in pure electric mode.

Changan CS75 PHEV is actually a plug-in hybrid version of Changan CS75, so it basically continues the design of fuel version in appearance, but changes in details. The change of the net style is the most obvious way to distinguish it from the hybrid version. The net has changed from the original horizontal stripes to the current similar mesh, and at the same time, the blue decoration has been added inside the net, which not only improves the recognition but also shows its new energy identity. In addition, blue elements have been added to headlights, fog lights and rims. The tail style has not been deliberately changed, but the exhaust is still bilateral, and the taillights are still designed through, which enhances the recognition. At the same time, LED strip is added internally, which further enhances the sense of exquisiteness.

The style of the interior will not give you anything particularly novel in design, nor will it deliberately emphasize its identity as a new energy source in color matching, and the overall look tends to be atmospheric. In addition, the details are handled well, the stitching on the center console is very delicate, and except for the lowest models, the suede packages of other models are handled with a sense of grade.

The flat-bottomed steering wheel is moderate in size and comfortable to hold. The back is equipped with paddles not for shifting gears, but for adjusting the energy recovery intensity. The car is equipped with six gears of energy recovery adjustment. The instrument panel is a 10.25-inch full LCD instrument, which looks very clear, but it is somewhat reflective under strong light.

There are no physical buttons on the air conditioning panel, and the design of touch buttons is adopted, which has a strong sense of science and technology. At the same time, the design of air volume, wind direction and temperature control is similar to that of the lever, which is very convenient to design and use. The style of the shift lever is different from the fuel version, and a new design is adopted. Behind the bar is the mode selection knob, which is equipped with ordinary, snow, sediment and mountain modes for the driver to choose.

The performance in space belongs to the mainstream level of the same level, the sitting is not crowded, the leg space is also good, the rear seats can support multi-angle adjustment, the central position is equipped with headrest, and the floor is very flat. The trunk has a good volume performance, and the interior is quite flat. The seat can support 4/6 ratio, and it is nearly flat after being laid down, which can further expand the loading volume. At the same time, there is a 220V power supply in the trunk, and the discharge power can reach 3kW, which can supply power for induction cookers and refrigerators used for outings.

In terms of power, Changan CS75 PHEV is a power system composed of a 1.5T engine, P1 generator, P3 front axle drive motor and P4 rear axle drive motor, in which the maximum power of the engine is 156 HP (115 kW) and the maximum torque is 225 Nm, the maximum power of P3 front axle motor is 70 kW (95 HP) and the maximum torque is 200 Nm, and the maximum power of P4 rear axle drive motor is 80 kW (109 HP). The maximum torque is 200 Nm, and the "three engines" consisting of front and rear double motors and 1.5T engine can output the maximum power of 255kW (349HP) and the maximum torque of 605Nm in hybrid mode.

In EV mode, the engine of Changan CS75 PHEV will not intervene even if the accelerator pedal is depressed deeply, but the maximum speed of the vehicle will be limited to 130km/h until the battery pack is exhausted. If you are in AUTO mode, the engine will work if you step on the accelerator pedal deeply, but the vibration of the gasoline engine will not be felt by the driver, and the whole process is still very quiet and smooth. In CHARGE mode, the generator will charge the power battery forcibly and charge the battery to a higher level, at which time the engine energy consumption will become higher, but not at an unacceptable level. Energy recovery has 6 gears adjustable and 0 gear closed. At this time, the subjective feeling of releasing the accelerator pedal is not much different from that of a conventional fuel vehicle. In the first 3 gears, the dragging feeling is not obvious, which has little effect on the ride comfort. When the accelerator pedal is set to 4 gears, there will be a slight dragging feeling.

● Recommended models

Changan CS75 PHEV has three models, and the subsidized price is 16.58-196,800 yuan. This time, we recommend the 2018 1.5T PHEV elite model, which is 13,000 yuan higher than the lowest model, but it can get active braking, full-speed adaptive cruise, electric adjustment of the passenger seat, heating/ventilation of the front driver’s seat, boss key and other configurations. Moreover, the model will be wrapped in suede with a sense of feel and grade.

● Summary:

Changan CS75 has performed well in the market since its launch, and the launch of its plug-in hybrid model has enriched its product line. The appearance style looks quite regular, and the changes in details have increased the recognition of the car. At the same time, the workmanship and materials used in the interior are satisfactory. In terms of configuration, Changan CS75 PHEV can also meet the needs of most users. Generally speaking, it is a good product.

Roewe eRX5

Subsidized selling price: 195,900-229,900 yuan.

Pure electric cruising range 60km

● Model introduction

Roewe eRX5 is a plug-in hybrid SUV that entered the new energy market earlier at this level. Among them, two models, the Zunrong flagship and the distinguished flagship, were listed in 2016, but the car added a hybrid exclusive version in 2018. Entry model. There is no difference in the appearance and interior of the three models, but the difference is in the configuration.

In appearance, Roewe eRX5′ s styling design is similar to the RX5 fuel version, but the mesh size is larger, and the chrome-plated hollowing treatment is carried out to enhance the layering of the front face. The headlight style is inspired by Yu Ruyi, and the NETGREEN logo on the front fender can be seen that it is different from the fuel version. There is a charging interface on the rear fender of the co-pilot’s side, which can fully charge the battery. The official charging time is 3 hours, and there is a fuel interface on the rear fender of the driver’s side. The car can be filled with 92 # gasoline. The rear enclosure style at the rear of the car is the best way to distinguish it from the fuel version, and its exhaust pipe also adopts a hidden design.

Compared with the appearance, there are fewer changes in the interior. At first glance, there is no obvious difference, and there is no intention to add some new energy elements. The workmanship and materials are good, and the positions that can often be touched are wrapped in soft materials. The color matching of the 12.3-inch LCD instrument UI design is also quite pleasing. It looks like there is no sense of disobedience, and the displayed functions are quite rich, and the user experience is good. I believe everyone is familiar with the large multimedia screen in the center. The zebra system is still very convenient to use, which may be due to personal habits. I always feel that it is better to set a few physical buttons properly.

In terms of space, the performance of eRX5 is enough for daily use. The experiencer with a height of 178cm has no sense of depression when sitting in the car. The rear row space is quite spacious and there is no pressure in the leg space. At the same time, the support of the seat is quite good. In addition, the rear seat can be adjusted back and forth in a small range, and the headrest is arranged in the center, which can improve the head support of the rear central passenger. The interior of the trunk is relatively flat, which is 537L in the standard state. At the same time, the rear seats can be laid down at a ratio of 4/6, and the volume can be expanded to 1518L after being laid down, but the only regret is that it is not a very flat surface after being laid down.

Roewe eRX5 is equipped with a 1.5T turbocharged engine with a maximum power of 169HP (124kW) and a maximum torque of 250Nm. At the same time, it is equipped with a motor with a maximum power of 56kW (76HP) to provide power for the whole vehicle. The power system of this system can generate a maximum torque of 702Nm. In addition, eRX5 is equipped with an ISG motor which mainly charges the battery with a maximum power of 30kW.

From my colleague Huang Zhengqiao’s previous test drive, we can know that when Roewe eRX5 is driving normally, the response speed of accelerator pedal is similar to that of gasoline version 1.5T model, but slightly slower than that of 2.0T model. However, it is easy for you to get addicted to this smooth and quiet feeling when driving in pure electricity. Even if you step on the accelerator more at low speed, the unique vibration of the gasoline engine will not appear here at all, unless you need to accelerate quickly, you will feel the intervention of the engine slightly. In the Normal mode, the engine intervention requires the opening of the accelerator pedal to reach more than 60%.

● Recommended models

Roewe eRX5 has three models, and the recommended model is Hybrid Connected Premium Ultimate. Although the entry-level hybrid exclusive version was launched this year, the car doesn’t have a series of configurations such as car networking, voice control and navigation, full LCD instrument, etc. Unless your car purchase budget is very limited, otherwise you might as well spend 14,000 yuan more to choose the premium flagship version of hybrid interconnection higher than it. First of all, the car can be equipped with zebra system, which is still good in practical use, and at the same time, you can add full LCD instrument, remote start and other functions.

● Summary:

In the compact plug-in hybrid market, Roewe eRX5′ s good reputation has been recognized by many consumers. Although the eRX5 has been on the market for two years, it is not out of date in terms of appearance and interior. The relatively good driving texture is also its plus item, and this year, an entry-level version with lower configuration was introduced, which enriched the choice space of consumers.

Today, I brought you four plug-in hybrid SUV models with a price of around 200,000 yuan. Among them, two medium-sized SUVs, Tang DM and WEY P8, can be said to be in the vanguard position of the current medium-sized plug-in hybrid SUV. The new generation of Tang DM is really eye-catching with its new style appearance and completely changed interior, and its good acceleration ability is also a highlight; WEY P8 is very sporty and exaggerated in design. This design once had a good evaluation in VV7, and now it is used in P8.

The compact SUVs Changan CS75 PHEV and Roewe eRX5 brought this time also have their own uniqueness. The good workmanship and interior of Changan CS75 PHEV are still very pleasing, and the good sales and good reputation of its fuel version also laid the foundation for it. Roewe eRX5 entered the market for a period of time, but it is not out of date at present, and its comprehensive strength is also good. How to choose these four models? I believe you have a preliminary idea after reading this article. (Text/Figure car home Liu Liwei)

Cctv news Liu Dianying, 60, lives in Tancheng, Linyi, Shandong Province. He has been working in Qingdao for one year and is usually responsible for cleaning Dandong Road. Liu Dianying’s work is basically from 5 a.m. to 5 p.m., because she needs to keep walking on the road, she often can’t eat on time, and most of the food she eats is cold.

A month ago, Liu Dianying found a refrigerator in front of a restaurant in Dandong Road. The refrigerator was full of dumplings, steamed stuffed buns and other foods. The words "free and appropriate use, no waste" were posted on the door of the refrigerator, and a sign was set up next to the refrigerator, which read: "Love charity station, small charity, great love." "Please heat the food. There is a microwave oven in the store for heating."

Since then, Liu Dianying can get food from the refrigerator and then heat it in the store, and often get hot meals.

The owner of this refrigerator is Liu Zheng, an out-and-out "post-90 s". After joining the army for five years, he returned to Qingdao and opened a restaurant, mainly engaged in breakfast and lunch. Although the store is not big, business is good.

Every day, there will inevitably be some unsold buns and meals left in the store. Liu Zheng feels it is a pity to throw them away. He used to give food to sanitation workers for free, and sometimes to homeless people lying under overpasses, but this is not a long-term solution. When Liu Zheng read an article about "sharing refrigerators", he came up with the idea of putting a refrigerator in front of the hotel.

Today, the refrigerator outside the store has been placed for more than 20 days, and the effect is good, mainly because sanitation workers come to take it. When the "shared refrigerator" was first set up, many people didn’t believe it, but after nearly a month, many people gave Liu Zheng a thumbs up.

While dedicating his love, Liu Zheng also paid special attention to food safety. He wrote the shelf life on the lunch box containing food and gave the sanitation workers free heating. He admits that there is still a long way to go to "share the refrigerator" and avoid becoming a "risk refrigerator".

"In fact, he often helped us before setting up a shared refrigerator!" Liu Dianying said, "Although people’s meals are said to be free, it’s still a little embarrassing to eat all the time! People helped me, and I can’t just be good at others. I can’t help you with other things, but when I walk to his door and see which ones are dirty, I will be rewarded! "

In the cold winter, a refrigerator warms people’s hearts. "I hope that people who can’t eat have a place to eat, and those who can’t eat don’t waste it." Liu Zheng’s way of offering love is more practical and environmentally friendly. It not only avoids the unnecessary waste of food, but also allows people who can’t eat or eat on weekdays to have a hot meal and do what they can to help others from their own reality. We should not only praise Liu Zheng’s love, but also learn from his idea of giving love. Let’s say thank you to Liu Zheng here!
