Before Mia joined Mercedes-Benz Motors, she was originally a technician in MTU, so for Mia, diesel engines are the field she is most familiar with.

If you want to achieve high power, it is not a difficult thing, the pile displacement can be, in the previous era, the engine was often several liters of displacement, and the tank engine was often dozens of liters of displacement, which was piled up by the reactor displacement, this backward technology was also considered by many people to be an advanced representative.

Tank engines, leading the trend of engines, at the same time, it is not possible to rely only on pile displacement, because there will be volume limitations.

Therefore, Germany has taken the road of high speed, anyway, the so-called maximum power, which is output at the maximum speed, the higher the speed, the greater the power will naturally be, and the consequence of this is a sharp increase in heat.

The big countries in the East will not take this path, they are still improving their 12150 diesel engine, even if it is the newly developed Panther diesel engine, it is also developed on the basis of the 12150 diesel engine, but in order to increase the heat dissipation capacity and expand the cylinder core distance, this engine, want to increase the liter power, will face a lot of problems.

The engine needs to have a more advanced turbocharger, so that the engine can draw more air and inject more fuel, which requires a high-quality oil pump and the right amount of fuel injection.

Therefore, this high-pressure common rail route is a must for the big countries in the East, ultra-high pressure fuel injection, there are too many problems to overcome, even the West is currently just researching, but here it has to be among them, but at the same time, she admires these people even more.

The engine of 1,200 horsepower from a machine plant, which has already been produced and is currently being tested, can be said? The current great power of the East? It has gradually stood at the same starting point as an old power like the United Kingdom.

Think that even Britain is only stopping at 1,200 horsepower? Didn't continue to bother with a more powerful diesel engine? The French took a shortcut, but also bypassed the difficulties in the research and development of diesel engines? The great power of the East, simply... Climb the Himalayas with tank diesels.

He thought of the phrase of this great country in the East? I think it's funny.

A great power in the East? What a magical country.

I know that Mia came to a machine factory, and many secrets can't be hidden, and people can guess it by guessing? Listen to the sound of tank diesels? You can judge what technology is used, but now, these are not necessary to cover up, and letting the outside world know the technology of the big countries in the east is obviously more conducive to the export of weapons by one's own side.

"We don't just have to think about? And do that. Qin Zhenhua said: "Mia, do you know engine technology?" Brother Qiang understands chip design again, so? If you help him, he will definitely be able to make the electronic control system of this engine. ”

Where is Mia smiling? Didn't say much? Is there affection in the eyes? Just then, there was another knock on the outside door.

"Brother Zhenhua, Brother Zhenhua, are you back? Really, you're getting more and more uninteresting, and you don't say hello when you come back. ”

Wang Erzhu is here.

As soon as he entered the door, the steaming dumplings were served on the table, and Wang Erzhu was not polite, he went to the kitchen to get chopsticks and bowls, and then joined in the fun and ate.

"If you want to say that this dumpling is still delicious at Brother Zhenhua's house, oops, when I just entered a machine factory, I used to eat it at Brother Zhenhua's house, at that time, the taste, tsk, I still remember it very clearly." Wang Erzhu sighed and turned into a foodie.

Because of Wang Erzhu's arrival, he forcibly interrupted the topic just now, and Qin Zhenhua could only pick it up again: "You don't just know how to eat, your car branch, how is it, this is the new year." ”

"Well, Brother Zhenhua, don't worry." Wang Erzhu patted his chest while eating: "Our automobile branch, this year's goal is 50,000 vehicles." ”

The scale of 50,000 vehicles, put in the future is not large, but now, it is definitely not small, you know, even if it is the national import of Steyr heavy trucks, the establishment of a special heavy truck joint venture company, the current annual output, is not more than 10,000, Wang Erzhu, actually said 50,000 such a goal.

"Fifty thousand?" Mia on the side really teased again: "It's bigger than our Mercedes-Benz company's tone, don't say anything else, do you have so many engines?" Do you want to equip more original Mercedes-Benz engines? ”

Wang Erzhu hurriedly shook his head: "No, the original version is too expensive, if we want to open the civilian market, we have to reduce the price." The production capacity of WD615 engine is quite insufficient, they seem to be afraid that we will rob them of their jobs, and have been compressing our supporting share. ”

Speaking of this, it is also a heart disease of Wang Erzhu, without me Brother Zhenhua, can you introduce the project so easily? Well, now that I'm afraid that we will compete, I actually reduced the quota.

"However, we don't care, at this time, we can see who is the pro and who is the queen, our own Beihua diesel engine factory has completely realized the localization of Deutz diesel engines, so it is no problem to equip Deutz air-cooled diesel engines." Wang Erzhu said: "Hmph, a living person can suffocate urine to death. ”

Originally, when the introduction of Mercedes-Benz heavy trucks, there were plans in this regard, if the introduction at the beginning, it must be even the introduction of Mercedes-Benz supporting the engine, but later, the Steyr project was introduced first, the supporting engine is also there, and then the introduction of a special Mercedes-Benz engine, some waste, in this consideration, the superior will decide to match the WD615 engine to Mercedes-Benz heavy truck.

In this way, Mercedes-Benz heavy trucks have three power systems, the original Mercedes-Benz imported engine, its own production of Deutz engine and WD615 engine, of which WD615 engine was originally developed as a civilian engine, so the price of this engine is the lowest, the highest cost-effectiveness ratio, is the most suitable diesel engine for trucks, but the production capacity is limited.

The Deutz engine is slightly more expensive, mainly for the use of military equipment, but now, since the supply of WD615 is not enough, then you can't wait, first use your own Deutz diesel engine, after all, Beihua Diesel Engine Factory, has also fallen into the name of a machine factory, is a subordinate enterprise of a machine factory, there is no need not to use your own, with outsiders.

The price is slightly higher, but the Mercedes-Benz car as a whole is not cheap anyway, besides, it eliminates the heat dissipation tank, which is advantageous in many areas.

"Well, the affairs of the automobile factory, you can do it yourself, pay attention, don't just mention the slogan, but implement it, we can't do the previous set of satellites." Qin Zhenhua said.
