The township cadres left happily, and the village cadres were left, and everyone was an old acquaintance for decades, so there were many topics to talk about. But after all, the village cadres still came for a purpose, and finally Secretary Peng mentioned the intention: "Teacher Shen, we are not here today for anything else, mainly I want to ask you to help the young people in the village find a job!"

Secretary Peng's request was more reasonable, but Shen's father couldn't agree immediately, because he knew that his son was taboo about this, so he took them to Huizhou. At that time, it was still just starting out, and I was afraid that it would affect the development of Changsheng Investment Group, but now the situation is different. With nearly 100,000 employees, it's nothing more than to help these hundreds of young people in the village get jobs. So Dad Shen pondered for a while and replied, "Secretary Peng, your request is very reasonable, but I can't agree to it right away." However, I don't think it's a big problem, and I'll give you an answer when I go back to Huizhou and ask my son. ”

"Oh, that's as it should be, thank you! The village officials immediately thanked him.

When the matter was settled, everyone happily chatted about the short topic of parents. For example: So-and-so old man has passed away, so-and-so's son has begged for a wife, and so-and-so has already hugged a big fat grandson.

After talking about the village, everyone asked Shen's father and Shen's mother: "Teacher Shen, you also have a grandson! I saw your daughter-in-law a few years ago." ”

Shen's mother was afraid that Shen's father would lose face by telling the truth, so she replied loudly: "We also have a granddaughter, my son is still young, and he will have a few more when the time comes." After saying these words, Shen's mother became interested, thinking that when she returned to Huizhou, she must have a son and they should give birth to a grandson as soon as possible. Otherwise, it would be a shame to step on such a topic again!

Shen Danqing, who was thousands of miles away, didn't know what Shen Danqing was thinking, he was inspecting the progress of the car power system at Changsheng Seiko, because he wanted to start filming future smart life commercials, so he desperately wanted a few cars as props.

Looking at the factory, rows of power systems are simulating live operation. Shen Danqing has a sense of pride in his heart, these power systems are not only Changsheng Automobile Company, but also can be said to be Chinese. Because the degree of advancement of these power systems can be said to have surpassed those of foreign countries.

There are several important indicators to measure whether the power system is advanced or not, first, whether it is numerical control. In the nineties, it was the beginning of the CNC improvement of automobile power, and foreign countries had just begun to study and improve. The Tang Dynasty automobile was fully numerical control from the beginning, and the engine was comprehensively managed from the aspects of intake and exhaust management, water temperature, oil pressure, idle start, starting motor, and fuel injection management, which is already the most mature engine CNC technology.

The second is whether it is energy saving and environmental protection. Needless to say, everyone knows this. With electronic valves and direct injection, energy savings are the ultimate unless turbocharging is added. Energy saving and environmental protection are actually related, energy saving will naturally be environmentally friendly, because energy saving, it proves that the fuel is fully burned, and the natural exhaust emissions are fully burned.

When it comes to turbocharging, we have to say that turbocharging is energy-saving, but it also has two disadvantages, the first is that it affects the driving experience, and its participation and non-participation are two completely different feelings, affecting the linear output of the engine. This is one of the reasons why many luxury cars do not use this technology.

Second, turbocharging affects the life of the engine, and its impact is similar to that of engine detonation. Its remarkable performance is that it is easy to cause engine oil to burn. Let's think about it! It presses high-pressure gas into the cylinder, which will definitely affect the tightness of the piston, the piston is a very light thing, and the application of an external force makes it not heavy, and it is easily affected.

The third criterion for measuring the sophistication of an engine is the compression ratio. This is intuitive data for the excellent standard of automotive performance per unit displacement. It is also proportional to the engine power, the higher the compression ratio, the greater the unit power, and the vice versa. Needless to say, there are electronic valves to control the intake and exhaust, which is certainly higher than the compression ratio of a normal engine, because it can artificially control the intake of more air, similar to Toyota's multi-manifold variable intake valve technology. But better. Because Toyota's vvT technology is a dull thing, it was set from the beginning. The electronic valve technology, on the other hand, can be adjusted to different operating conditions. For example: idling, low, high, these working conditions are different, so they cannot be generalized.

This is about the engine, and most importantly, the automatic transmission technology. Before ninety-five years, there were only two automatic transmissions, CVT and AT. Among them, the CV.T has only 4 gears, and the AT has 6 gears. In terms of driving experience, the AT is better than the CVT, but it is also not comparable to the manual transmission of the MT. The most intuitive thing is that the racing car only has a manual gear, and the manual gear has high transmission efficiency and fuel saving. However, the disadvantages of manual transmission are also obvious, in the complex road conditions in the city, due to the frequent start and stop, it is far less convenient than automatic transmission.

The AMT studied by Guo Dong is based on the manual transmission, and the electronic control system (EcU) is used to control the cooperation between the hydraulic shift mechanism, throttle and clutch to achieve the purpose of automatic gear shifting. It also has a disadvantage, that is, there is a sense of pause when changing gears, which affects the driving experience. Now all they have to do is to minimize this sense of pause, nothing else, just change gears fast, so fast that people can't perceive it, and it's a success.

Shen Danqing chose AMT mechanical automatic transmission technology, but there was no way, other roads were taken by others, and there was only one way left for him to go. However, the advantages of AMT are also obvious, it can be manually and automatically converted arbitrarily, saving fuel. There are two disadvantages, one is that there is a sense of pause in shifting, which must be improved by increasing the speed of shifting. The second is that there is no P gear, which requires another parking system, which is actually an electronic braking system plus a gear, and an artificial set of P gear. When parking, just put the gear into the P gear, and you don't need to pull the handbrake, which means that the handbrake is canceled. In this way, their automatic gear mechanism has 4 gears, namely D gear (forward gear), N gear (neutral), P gear (parking gear), and R gear (reverse gear).

"Dean Guo, can you speed up a little faster? The company's future smart life advertising film needs to use several kinds of cars. Shen Danqing asked Guo Dong, who was accompanying him.

"Boss, I'm really sorry, the system debugging takes a lot of time, whether it is the engine management system or the automatic gear system, it takes a lot of measured data, you can see, we have done our best. Guo Dong pointed to the engine system that was simulating the live operation of a factory building.

"Okay! If the test is successful, let me know right away. Shen Danqing said helplessly. Then he went away with his head down and without looking back.

At this stage, the most time-consuming thing is the engine system, the chassis does not take time, and the technologies of each subsystem are studied, but the different models are fine-tuned. However, in the future, the chassis is also the most prone to problems, it is not like the engine that has done a lot of testing in advance, it has to install the power system, drive on the road, and then start testing, this test period is a bit long, it will take two to three years. There is also a professional term called running-in, that is, the running-in between various parts, where there is a problem, it is necessary to find out and improve. The main reason why the development cycle of a car is so long is here. Of course, as long as there are a few mature chassis, it will not take so long to design new models in the future.

However, Shen Danqing has a way to shorten this test time, maybe half a year is enough. It is a brutal solution, that is, to directly produce a large number of experimental vehicles for use as express vehicles, taxis, and employee vehicles. When the average company tests, where will so many cars be used, naturally only take more time.

For example, the reason why the spring C1 is designed to be so small is that it is planned to be an express vehicle, which is to replace the electric tricycle of later generations. Electric tricycles can't be licensed, and again, the safety performance is really a little worse. The traffic police always check them.

Spring Reach is the car with the same chassis as the Tang Dynasty A4, which is a brand that Shen Danqing finally came up with. It was a B-class car, and it didn't seem appropriate to call it B, so he replaced it with a Chinese name. From the beginning, the spring Reach was planned as a luxury taxi, with the aim of being a large number of test cars. He will not open a taxi company in one or two cities, but will open it in the more economically developed cities of the country. At that time, it will be an experimental model of tens of thousands to 100,000 units, and you see that its chassis will mature quickly!

Without further ado, let's go back to Shen Danqing, after he returned to the company, he went to the automotive design team again. In China, it's the appearance that counts. Therefore, Shen Danqing grasped it very tightly, and every car had to pass his eyes.

He first went to the designer who designed the Spring Reach to see how he was doing?

It's a taxi, and that's what the designer recognizes. He designed the car to be neither ostentatious nor modest, similar to the positioning of the Tang Dynasty A6 Elite Edition.

It is a bit similar to the design of the middle mesh of BMW's kidneys, that is, the oval mesh is slightly concave in the middle, but it is not spaced out like the BMW grille, and its middle is the emblem of the spring car, an eagle with wings fluttering and diving, and its claws grasp a row of spring flower pinyin letters, but the eagle is just a simple abstract design. The headlights of the front car are very ordinary, which is the style of the human eye. In this way, the character of the front face of the car comes out, unassuming but very attractive.

The roof is also very special, in order to take care of the rear seat passengers, the roof is relatively flat, and it only begins to sink in the back two-thirds of the position, and the sinking is not large. However, the trunk is hidden, almost more than half is hidden in the passenger compartment, so that the ratio of the engine compartment and the tail compartment from the outside is relatively large, reaching a ratio of 3:1, and the engine compartment is very long, so that the high-end attributes of the car are more obvious.
