Mia opened her eyes wide and looked at Wang Xiaoyu incredibly. Wang Xiaoyu spoke in a simple and easy-to-understand manner and clearly stated.
In the past, diesel engines were naturally aspirated. If you want to increase power, you need to increase the displacement. Therefore, in the past, it was often thirty or forty liters, but the performance of the engine was actually not particularly high.
Then, the turbocharger technology comes out. With the same displacement, as long as more air is blown into the cylinder, the engine can spray more air and participate in the combustion. In this way, the engine's power will naturally
The improvement has been made. Now, the continuous improvement of engine technology is actually mainly due to the development of this supercharge technology.
However, no matter how the supercharger increases its performance, it has a limit. It is subject to basic physical principles. Take the most commonly used exhaust gas turbocharger for example, which requires the engine exhaust gas to drive it.
The performance of turbine blades at low speeds cannot be improved. Only at high speeds can they have strong thrust, while the supercharger consumes engine power, etc.
There are various differences in various methods. Now, although the turbocharger is getting stronger and stronger, it is still impossible for the tank engine to easily achieve a power output of 1,500 horsepower.
So, at this time, the strange French people came up with a solution. Their supercharger was not made of exhaust gas or mechanical supercharger, but a small gas turbine!
It is just a V8 engine, which is also the reason for its small size. The V8 engine is a gas turbine code-named TM307B. This gas turbine promotes the supercharger, so the supercharger
The performance is greatly enhanced, achieving ultra-high pressure.
The greater the pressure, the more fuel it can inject, which greatly improves the engine's power output. The power of 1,500 horsepower can be achieved in this way.
It can be said that there are many benefits. This special supercharger has nothing to do with the diesel engine. Therefore, even at low speeds, it has quite powerful power, improves torque and makes the tank's acceleration excellent, but at the same time
, and there are some disadvantages that follow.
First of all, it is the overall reliability.
A single diesel engine or a single turbine may be reliable, but when combined, the reliability will definitely be reduced, and at the same time, it will greatly increase the engine structure!
After all, the combined power is to use a gas turbine to promote the supercharger and enhance the supercharger's superchargeability. Its TM3O7B itself is a gas turbine that can work independently, so it must be equipped with a relatively independent supply.
Oil, air intake and lubricating oil pipelines, and this thing also needs to be started by itself to work, so there is also an independent startup system and control system.
Therefore, this power pack has a complex structure and a failure rate that can be imagined. Moreover, for users, they not only need to be able to maintain diesel engines, but also have to be able to maintain gas turbines! Moreover, the price of gas turbines is not cheap!
In short, this power system is a waste of money to the eyes of insiders, but this cannot deny the efforts of the French, because it is not that good to achieve a power of 1,500 horsepower.
It is easy to achieve, and taking a different approach is just a solution.
Just like in order to develop a turbofan engine, they also independently worked on it, and finally came up with a unique single-rotor engine. Although the performance is not strong, it can be used.
"The French really have ideas." After listening to Wang Xiaoyu's introduction, as a technician of MTU, Miya also felt her horizons: "They have been talking about super high-pressure diesel engines, and we thought they had made something.
As for the advanced turbocharger, it turns out that this is how to achieve power increase."
Mia mainly works as a supercharger. She has accumulated rich experience in this area and also knows how many difficulties there are. It is not so easy to continue to increase the pressure of the supercharger. The French turned out to be
Use a gas turbine as a supercharger!
"Yes, according to their plan, this gas turbine can be used alone. It can be used to start the engine and be used as an auxiliary power system. In short, their fantasy idea is still eye-opening.
.” Qin Zhenhua said: "I just don't know what the actual effect will be."
"The actual effect is definitely not as good as our diesel engines." Mia said: "They can use such a complex power for their own use. If exported, no country is willing to use it. It seems that we have to make a backup plan in advance.
If the French exported this kind of tank, they would have to replace the engine of our MTU company."
"If the French were here, they would probably be furious." Qin Zhenhua said with a smile.
Mia is right. Such a complex power unit may be able to maintain such a complex power unit, but if it is exported to the third world countries, it is estimated that there are no such maintenance personnel, and they will not be able to handle it at all. The French want it.
To export tanks, German engines must be installed in the end, which is definitely a big blow to the arrogant French.
Qin Zhenhua also deeply agrees with Miya's proposal.
"Mia? Are you here? Huh, Mr. Qin, here too? Who is this beautiful lady?" At this moment, suddenly, someone walked to their table and started to greet him.
"Mr. Schultz?" Qin Zhenhua looked at the other party and immediately recognized him. The person who came was the sales manager of Mercedes-Benz Motor Company. Last time he came here for negotiations, it broke out in a bad mood. This time, the other party actually took the initiative.
Find it here?
I happened to meet it? Of course it was not like this. The other party came here like this, either Mia revealed it or the other party found out the news. In short, since the other party has come, it means that the other party can no longer sit still.
Back then, they thought they had to pay for their own side and they had to give them whatever price they wanted. Who would have thought that it was not the case. They turned to Steyer Company. Now, the agreement with Steyer Company is gradually
At the finalization stage of the land, Mercedes-Benz is probably in a hurry?
Last time, I took the initiative to come to my house, and I was arrogant, but I thought my party had no choice. Mercedes-Benz was of course proud, but now, Mercedes-Benz has found that it has missed the opportunity. Once it fully introduces Steyer technology, it won't be
If they need to cooperate with Mercedes-Benz, they will lose a huge market.
