Chapter 2910

Want to buy our technology, and then you can lie down and make money? Of course, that's impossible. Our goal is to build factories overseas. President Qin said that in those years. Now, looking at the red flag car and heavy truck factory, they all start to build factories overseas. Now, it's their turn to build Haihe automobile factory.

Unfortunately, it's not Europe. It's just a backward kimchi country. Well, let's practice with kimchi countries.

R & D department.

"The main products developed by our R & D department are 1.5-liter engine and 8-speed automatic transmission." when we walked into the door of the R & D department, factory director Zhang said to each other.

1.5 litres? Hearing the other party's words, Zheng Zhouyun was happy again. He had just developed the same 1.5-liter engine. He couldn't help asking, "what are the power parameters of your engine?"

"We divided it into two series, high-power and low-power versions, of which the low-power version is at 150 horsepower," factory director Zhang said.

Hearing this, the other party's heart clattered. The low power has 150 horsepower. Think about your power of just over 100 horsepower, it can't be compared anyway.

"What about the high-power version?"

"198 horsepower," said factory director Zhang, "although it can still be increased, a compromise has been made for the sake of life."

198 horsepower, do you want to go against the sky? Zheng Zhouyun heard each other's introduction and immediately felt that the products they developed were rubbish.

wait!

"All your engines are turbocharged?" Zheng Zhouyun asked. If you want to squeeze out so much power, it must be turbocharged. How can self-priming power be so strong?

200 horsepower, enough for a self-priming 3.0 engine.

"Yes."

"Then why don't you develop a self-priming engine?" Zheng Zhouyun asked.

At this time, they have stood in front of the display, looking at the compact volume of the engine, and then looking at the turbine hanging on the side, they can know that the other party has been fully turbocharged.

"Self priming version? Self priming engine will be eliminated sooner or later. Our vision is long-term. Of course, we should start with supercharged engine." factory director Zhao said: "most countries collect taxes according to the displacement. Our engine has a great advantage in doing so. What do you think, President Zheng?"

In fact, turbocharged engines are not new.

After all, the purpose of doing so is to improve the engine power, and the most direct way is to increase the displacement. However, with the increase of displacement, the precision, weight and energy consumption of engine manufacturing have also been infinitely increased. In particular, countries pay more and more attention to environmental protection. Cars have to charge different displacement taxes according to displacement.

The purpose of increasing displacement is actually to increase air and fuel. Therefore, as long as the engine can forcibly suck more air and fuel mixture into the cylinder combustion chamber for work in the same unit time, it will improve the combustion efficiency. This is supercharging, which can increase the power by 30% or 40% compared with the same naturally aspirated engine.

Supercharging was first introduced. The output shaft of the engine was used to directly drive the supercharger, which would consume a certain amount of energy. Anyway, the exhaust gas emitted by the engine was supposed to be discharged. If the exhaust gas was used to drive the supercharger, there would be no waste of energy. This is turbopressurization. In fact, in the 1970s, the car began to use turbocharging.

However, in civilian vehicles, I always feel that the turbocharger will not be used because of its short service life. In fact, more importantly, most automobile factories do not have this technology.

Haihe automobile factory also made great efforts to study. The first thing to do is a 1.0L turbocharged engine. After all, it is easier to do it on the original basis. Later, the technology became more and more powerful. At the suggestion of Qin Guan, it put the displacement on 1.5L.

The displacement of Hongqi car starts from 2.0. In this way, the domestic automobile engine will form a complete industrial chain.

Turbocharging must be the trend in the future. How can we compete with the century old car companies on the self-priming engine? Therefore, if you want to rise suddenly, you must take a new technical route.

This is the reason why Qin Guan decided to go on Turbocharging. We can see from later generations that even the car enterprises of the most stubborn island country say what self-priming car enterprises do every day, and finally go on Turbocharging. This is the river of history and the inevitable result of the development of the automobile industry.

Han started in advance. When these countries were still playing self-priming, they registered all the patents of turbocharging. Let's see how they play in the future!

Take modern cars for example. Do they want to play turbocharging? It's impossible to develop without a few years of research and development. Now, they absolutely don't have this strength. It's impossible to do it directly from scratch.

"Is there a problem with the turbine life?" Zheng Zhouyun asked.

"What we are studying now is how to improve its service life and reliability. Our plan is that the turbocharger and engine have the same service life, which is our quality standard."

We have to start with one shot. When we first launched the turbocharged model, it must be tall, but later, when we found that the turbocharged model burned oil and the service life of the supercharger was short, it would greatly affect the reputation.

It's like when talking about EA888, all the jokes will say that oil is burned. In fact, it's the first two generations. By the third generation of EA888, oil is no longer burned. However, some people will still say this because of the impression they left in the past. This is a bad aspect.

There are also good aspects, such as Santana, which is strong and durable. If you really own Santana, you are not afraid to travel all over the world. Therefore, the public's reputation has risen. Many people recognize Santana when they buy a car. Even if it is drum brake and there is no ESP, they feel happy.

"At the same time, the future cars will inevitably focus on automatic transmission, and there are more and more gears. Therefore, we put the gears on eight in advance. The more gears, the better the engine can get a suitable match and reduce fuel consumption." factory director Zhang said: "Our goal is to achieve a minimum comprehensive fuel consumption of 6 liters per 100 kilometers when driving a car with a self weight of 1.5 tons."

Regardless of the size, form and working condition of the car, we can directly talk about the fuel consumption, that is, playing hooligans. A 1.5-ton car should be regarded as a medium-sized car. It should at least match the 2.0 engine, and the comprehensive fuel consumption is more than 12 liters per hundred kilometers. Now, they want to reduce the fuel consumption by half.

Zheng Zhouyun didn't dare to think of these. Their cars can be sold on sale as long as they make a beautiful shell. As for fuel consumption, if the steel plate is thinner and the wheels are narrower, the fuel consumption can still be reduced.

However, it can never reach this level, which is to technically reduce fuel consumption.

The technology here has been comparable to that of the old automobile country for hundreds of years!

For modern automobile, this is a rare opportunity. What about joint venture and not holding shares? If these technologies are applied to modern automobile, they can definitely dominate the whole world!
