However, simply relying on a car can not form a series, after consideration, Jiang Yan got out the rather classic Land Rover car in later generations, but she did not completely copy the appearance of Land Rover, but re-set it according to the characteristics of Hongqi cars, which is a mid-range car.

The engine of the car is 200 horsepower, because its chassis is relatively high, it can be applied to very bad roads, the operation is simple and rude, it is a light off-road vehicle with relatively high horsepower, so this car Jiang Yan named Hongqi L1.

As for the convertible sports car, Jiang Yan naturally has an idea, but now, there is no market for sports cars in China, thinking about it, considering that the previous Hongqi car is too high-end, he also took advantage of the appearance of the Audi car, combined with the Hongqi car, also made a new car, also aimed at the mid-range.

The appearance is more calm and atmospheric, more in line with the golden mean, Jiang Yan named it Hongqi L2 car.

The first thing he did was the overall design of the whole vehicle. The car will be made of titanium alloy with a large number of high-strength aluminum alloy materials to achieve the ultimate lightweight.

The power is the more advanced 3.5-liter V6 turbocharged engine that I already know, with a maximum horsepower of 280 horsepower, which can accelerate to 100 kilometers per hour in 8 seconds and exceed 220 kilometers per hour.

So the master began to describe the parameters of the Dongfeng truck and its strong performance at the test site. As a result, many people now want to see this car with their own eyes.

Through lightweight design and the use of high-strength materials, the power and weight of this Hongqi flagship far exceed that of foreign sedans of the same level.

"What do you know, the precision of the machines in the workshop of our research institute is high, and some precision parts of the cars produced are not allowed to be processed and produced in the workshop of our research institute, as well as the power workshop, and now some of the engines of many cars are produced in our power workshop."

。

In order to achieve lightweight, Jiang Yan used titanium alloy to make the entire frame, creating a relatively light and extremely strong overall frame. This will significantly reduce the weight of the entire vehicle. At the same time, the exterior parts such as doors and hoods will also be made of aluminum alloy.

"The reason why people gave us this business is not the credit of our Chief Engineer Jiang." Another veteran worker spoke.

"Yes, yes, he really can, if I hadn't seen it with my own eyes, I wouldn't have believed we could build a car like this!" One of the workers sighed when he heard the master's story.

After several days of busy work, Jiang Yan finally completed the design drawings of each part of the three Hongqi cars, which add up to a total of 2,000 small sheets, looking at these drawings, Jiang Yan was satisfied.

This was unprecedented at the time.

When Jiang Yan was working hard to design the three Hongqi series cars, colleagues in the research institute were discussing the recent deeds of Jiang Yan to build Dongfeng trucks.

"Isn't that better than the performance of our current main liberation truck?" The young man asked.

Lao Wu didn't speak, and gave the young worker a blank look.

"Do you know, I heard from a friend in the secretariat that now our Chief Engineer Jiang is going to build a new car!" A middle-aged worker called Lao Wu by the workers spoke mysteriously.

"What! Chief Engineer Jiang designed the car. A young worker exclaimed.

……

"It's not that Chief Engineer Jiang designs a new car that is good for our research institute, and we don't produce this thing." Another worker asked.

The suspension system uses aluminium alloy control arms and shock absorbers, which are not only lightweight, strong, but also capable of precise handling. The braking system uses titanium alloy four-wheel disc brake, with anti-lock braking system, and the braking distance is shortened to less than 30 meters.

"Otherwise, he is our chief engineer." The old master spoke.

"That's for sure, how much does the liberation truck load." The young worker's master said with a mysterious face: "A friend of mine is in our warehouse, and when he was testing the weight, he was moving things in the warehouse, and I told you, but he was much older, and I also knew a lot from other workers, so you listen to me slowly." ”

Everyone talked about it, and they were all eager to try the news that Jiang Yan had built a new car, and they all imagined what kind of new car he would build that shocked the world.

"It's really rare and strange, the "Jinggangshan" car that often runs on the road now knows no, he is the car designed by our Chief Engineer Jiang before. Design another one, it's not a hand-held pinch. Lao Wu said disdainfully.

"I have participated in some projects, but I have really seen the assembled trucks, to be honest, I have seen a lot of cars at home and abroad, but I patted my chest and said that the truck designed by Chief Engineer Jiang is the best truck I have seen so far. It's better than the appearance of liberation," said the worker's master mysteriously.

"Ahh This is also the car designed by our Chief Engineer Jiang. The young worker spoke.

For the titanium-aluminum alloy parts of the body, he handed over the design drawings to a workshop, which had some equipment that Jiang Yan had taken them to produce titanium alloys before, which could manufacture lightweight, strong titanium-aluminum alloy parts.

In terms of engines, Jiang Yan divided the design drawings to the sixth and seventh workshops, and the sixth and seventh workshops were engine manufacturing workshops, which produced the "Jinggangshan" sedan series engines, the "Yanjing" jeep series engines, and even borrowed some armored infantry vehicles and self-propelled artillery engines. Here are his trained precision machining experts who can handle complex engine components.

Let his secretary Xiao Gong find the minister of the Ministry of Science and Technology, distribute his drawings to them, and let the Ministry of Science and Technology take out the hands to copy a few copies of such drawings.

In the car, Jiang Yan also deliberately added some things such as the radio, and the seats have also been specially designed, which can completely use the human body, comfortable to sit in the car, and can automatically adjust the position, in short, everything is in accordance with the high standards of this era.

"Also, I've heard that the car designed by Chief Engineer Jiang uses new materials, but I don't know what the specific material is." Lao Wu shook his head and said.

However, the key crankshafts, camshafts and other components, Jiang Yan still handed over to the five-axis linkage machine tool workshop that he had just developed successfully to manufacture for precision manufacturing.

"I heard that our Chief Engineer Jiang has built a super powerful truck? Master, are you still involved? A young worker asked his master.

After the drawings came out, Jiang Yan called the directors of each workshop that needed to be processed to a conference room, and distributed these drawings to different sections according to the production capacity and performance of their workshops.

The manufacture of mechanical components such as gearboxes and shock absorption systems was handed over by Jiang Yan to the mechanics of the mechanical workshop. After all, this machine cannot reach this kind of accuracy now, and some of them still need senior workers to do it.

As for the processing of some exterior decoration and interior, he drew drawings and asked Xiao Gong to hand them over to Liu Haizhong for their workshop to produce, and even he found some skillful needleworkers to use for production
