When he uttered this sentence, even Chen Dongqiang himself felt incredible, how could he tell the other party the real thing?Is it because what Qin Shaoyou said just now has made it impossible for him to refute Qin Shaoyou theoretically, so should we be more practical?

Let's see what this person has to say, a technical school student, what real skills can he have?

"That's right, Qin Shaoyou, you are someone who is valued by German consultants, please tell the big guys what you think." Li Ming said from the side.

"The best thing is of course forward research and development, so that we can thoroughly understand the principle and technology of the engine." Qin Shaoyou said: "However, I also know that the time span of forward research and development is long and consumes a lot of funds. If there is no result, it will be dismounted in some gossip."

Gao Zhongzhong nodded. Although this Qin Shaoyou had only been in the factory for a few months, he was already familiar with the factory system.The technology of the engine is very difficult, it takes a long time to develop, and the investment is large. Even if the current factory leader supports it, after a few years, the new factory leader will come up, and the attitude will be unknown. If some people slander, the project is very likely It will turn yellow.

It is not good to be eager for quick success, but under the current situation, we must also take shortcuts.

When Qin Shaoyou said these words, he looked directly at Chen Dongqiang: "Chen Gong, am I right?"

Chen Dongqiang was secretly annoyed, this guy was making fun of himself!Said he would spread rumors.However, there was no need for Chen Dongqiang to argue with Qin Shaoyou, he said: "What specific thoughts do you have, just say it."

"For us, the most advanced engine at hand is the one on Santana." Qin Shaoyou said: "If we want to achieve results in a short time, we have to find a way on this engine. We Make an upgrade of this engine as the first project, so that it can output a steady 150 horsepower."

"Tsk tsk, we just came to our technical department, and we are going to put satellites on for us." Chen Dongqiang said: "Our existing engine can only output more than 80 horsepower, and now we need to upgrade the engine to 150 horsepower, which is simply an improvement. It’s twice as powerful. Even Audi can’t compare to it, and the German consultants are right.”

Following Chen Dongqiang's ridicule, several people wanted to join in, and Qin Shaoyou shook his head there: "The frog at the bottom of the well."

"What did you say?" Chen Dongqiang was annoyed. In the past, Gao Zhongcheng dared to criticize him, but now, a new technician dared to criticize him as a frog in a well?

"The 1.6-liter engine used on our Santana is durable and has great potential for modification. It is not difficult to increase its power to 150 horsepower." Qin Shaoyou said: "I can't believe this, it's not a frog in a well What is it?"

150 hp?Look at those 1.5t engines of later generations, tuned to nearly 6 horsepower, that is called heaven-defying.The old 1.5t model of the Great Wall h1.5 is to hang a turbo on its own 150-liter engine, which easily reaches [-] horsepower.A guy who has never seen the world.

"Okay, tell me, how do you plan to increase the power to [-]?" Chen Dongqiang asked through gritted teeth.

"Hang the turbo." Qin Shaoyou said: "Naturally aspirated engines are strong and durable, and have low maintenance costs. However, their power improvement is limited and their fuel consumption is high. Therefore, with the gradual upgrade of regulations, turbocharged engines will gradually become Mainstream, we are now going to carry out relevant technology pre-research, and stand on the same starting line as foreign countries.”

A naturally aspirated engine relies on the piston to actively suck air into the cylinder during the intake stroke. This kind of power output is relatively linear and is well received by users. Therefore, many old drivers will despise turbocharged engines, bah, Squeezing power, short life, maybe one day the turbo will break down on the road.

Naturally aspirated is of course good, and the sound of the air waves is even more addictive. However, this needs to be preceded by a few words, that is, large displacement.A naturally aspirated engine with a large displacement is really good. As for the small engine with a displacement of 1.6 liters like Santana...

The turbine is a super large electric fan that blows more air into the cylinder of the engine to participate in the combustion, so that more air enters, more fuel is injected, and naturally more work is done, which can increase power.

In fact, if Qin Shaoyou was given enough time and funds, Qin Shaoyou would also be willing to develop a powerful large-displacement self-priming engine for appearance, but now, it is simply impossible.The time and money spent will definitely ruin the entire project.What Qin Shaoyou needs is a product that can be produced in a short time, and that can also scare people.

I can nearly double the power, are you convinced?No matter how many qualifications you have, with me, it's all floating clouds!

(So, readers who like self-priming and dislike turbos, please don’t complain. In the future, our protagonist will definitely develop a large-displacement self-priming, which will be used in our parade vehicles. We must also have a luxury car that can rival the standard tiger. Yes. Now, let’s pretend to be aggressive first.)

"It is said that Volkswagen is also developing turbocharged engines. In this case, we can stand on the same starting line as the Germans. However, will there be great risks in the development of this technology?" At that time, Gao Zhongzhong had already calmed down and analyzed the problem. Of course he knew that it would be fun to talk to Chen Dongqiang casually, but if he decided on a course, he had to be serious and responsible.

Qin Shaoyou nodded sincerely: "The biggest problem lies in materials and craftsmanship. If it is not mature, it may cause early damage to the turbine and leave a bad impression on users."

The most difficult part of building a car is the materials and craftsmanship. Now to improve the localization rate of Santana, it is stuck here. Many materials have to be imported, and a lot of processing equipment has to be imported. If you want to achieve domestic production, you have to buy a lot of related equipment. It is not simply to produce a car, but to stimulate the entire car-making industry to form a complete industrial chain.

In fact, in later generations, it is quite simple to add a turbo to a self-priming engine. You only need to buy a kit from the Internet, install it, and then refresh the ecu (computer that controls the engine), and you can swish Increased engine power.

It's a pity that there is no mature supporting industrial chain in this era, so Qin Shaoyou has to solve these problems by himself.

"Hmph, it's self-knowledge." Chen Dongqiang glanced at Qin Shaoyou.

"If I start from now, it will take me about a year, and at the same time I need a certain amount of financial support." Qin Shaoyou said: "After all, there are a lot of changes to be made. The carburetor has to be changed to multi-point EFI. To save fuel, variable valve technology is also required. The piston rod needs to be strengthened, and the turbine is still the most difficult. Small inertia and even variable section turbines need advanced numerical control equipment to manufacture..."

"What did you say, a year?" Chen Dongqiang opened his eyes wide.

The development of an engine usually takes five to ten years, or even longer. Even if a mature engine is equipped with a turbine, it is impossible to solve it in a year with the current domestic technology!
