"We believe that although the Panther diesel engine has improved the cylinder structure, there is still a problem of insufficient overall strength." The next day, when the meeting restarted, there had been some changes in tone.

An engine expert put forward his opinion, if you want to reach 1200 horsepower, and even 1500 horsepower in the later stage, it will require quite high in-cylinder air pressure.

The current 150 engine, after all, the piston diameter is not large, if you want to get enough power, you need to have a stronger internal pressure, at this time, the strength of the cylinder block, can it meet the requirements?

They were skeptical.

"Yes, we also think that it is possible to expand to 1200 horsepower, but to reach 1500 horsepower, it is estimated that it is still not enough, and there will be various problems in the future, and when the time comes, it will come to a dead end."

At present, 1500 horsepower engines are still rare, but it is conceivable that after ten or twenty years, the mainstream tank engine will definitely transition to the 1500 horsepower level.

Since a machine factory is aiming for 1500 horsepower, everyone has to pay attention to it, the strength of the body, is it enough?

"Yes, the German diesel engine, the diameter of the piston is larger, since they all choose so, they must have their own concerns, we improve the existing engine, I am afraid that we will encounter problems."

"Guys, if we can't solve the problem ourselves, how about cooperating with the United States? We contacted the Ricardo Engine Research Institute in the United States, and we worked with them to rebuild and develop our 12150L tank engine, how? ”

Since the opening of the door, the relationship with the West is still very good, especially the United States, in recent years, the relationship between the two sides has been deepening, and the country has also organized a delegation to the United States to investigate, after World War II, the United States' scientific and technological strength, that is the most powerful, so if you find them to cooperate and improve, it will definitely be easier to succeed.

Everyone, every word you say, every word I say, are all making suggestions, and in the face of today's scene, Qin Zhenhua couldn't help but let out a sneer in his heart.

This wind direction is changing a little fast, which is clearly the rhythm of isolating a machine factory.

Also, the habit of eating alone in a machine factory is not good, Mu Xiu will be destroyed by the forest wind, and a machine factory is successful, and the engine will be compared, and there will definitely be many people who are not satisfied.

Moreover, their worries, theoretically speaking, also have a certain reason, after all, this level of engine has not been developed in China, and it belongs to crossing the river by feeling the stones.

However, when he heard about cooperation with the United States, Qin Zhenhua couldn't help but speak up: "Relying on foreigners is unreliable, how can foreigners take out advanced technology to us, if we cooperate with the United States to transform, then the final outcome is that the United States helps us to transform, we spend money to buy, technology or something, it is impossible to learn at all." I may not know anything else, but I can still speculate on this. ”

Can't figure it out yourself, and then pin your hopes on foreigners?

Wake up, how is this possible?

These few times I went out, Qin Zhenhua has seen it very clearly, the technology of imported tank guns, 120 mm is no way, people are only willing to give 105 mm, imported engine technology, there is no way, the British agreed to give a prototype, what is the result? In the end, nonsense said that it sank to the bottom of the sea.

If you want the most advanced, everyone hides it.

The West wants to help us, but to make us truly strong, we still rely on ourselves, and others can't be relied on!

In the morning meeting, everyone spent this kind of discussion, and no one mentioned the engine project of a machine factory.

And in the afternoon, finally, the engine threw out their plan.

"We now, relying on our own technology, surveying and mapping imitation 8V331 engine, has entered a dead end, however, for the development of our domestic engine technology, therefore, we can only grit our teeth now, continue to import technology from abroad, I suggest that the state fund, the German technology to buy."

It was Wu Liquan, the director of the engine institute, who spoke, and finally spoke. Yesterday, even if they were reporting work, they were introduced to Xiang Dayang, and today, the director finally started their plan.

Since our surveying and mapping imitation can't work, let's just buy it!

Hearing this, Qin Zhenhua was silent, clenched his water cup tightly, and almost crushed it.

Buy, buy, buy! Can you buy modern national defense by buying?

However, he still can't intervene in this kind of thing.

"If we don't ask for help from the outside world, then the research and development in the past few years will be completely wasted, and we have consumed a lot of national resources, so we have no other choice now than to continue to walk firmly until the day of success!"

If you don't buy it, the previous investment will be wasted, and what if you buy it? After I buy it, is it guaranteed to be successful? Amusing! Will people sell real technology?

At this time, Qin Zhenhua was already a little annoyed, but he still remained calm and restrained.

"We just learned that MTU has continued to develop on the basis of their 8V331 diesel engine, and the latest model called the 396 series engine has been made."

This diesel engine, like the 331 diesel engine, belongs to the water-cooled, four-stroke, intercooled, direct-injection engine, the technology is leading in Europe, in the world, the cylinder diameter is still 165 mm, but the piston stroke is increased to 185 mm.

As a series of engines, divided into 6, 8, 12, l6 cylinders, V-shaped structure, the angle of 90 degrees, through different cylinder numbers and oil cut-off control, the power can be between 345 and 1920 kilowatts, and the later improved models can even reach a terrible power output of 3000 kilowatts.

"It has new technologies such as cylinder drain oil, cylinder charge conversion, sequential turbocharging, electronic governor, metal plate cooler, three-layer wall cooling exhaust system, etc., these technologies are currently lacking in our country, so, after the introduction, this engine can be widely used in various ships, large-tonnage mining dump trucks, oilfield machinery power, railway locomotives, construction machinery, power generation equipment, special vehicle power, etc. Therefore, after the introduction, it can be regarded as a military-civilian diesel engine, which makes the greatest contribution to the country's economic development and army construction. ”

This diesel engine is not only used as a technical reserve for tank engines, it can be used from warships to generators! This vision, this positioning, are quite lofty.
