Chapter five hundred and sixty-six wood show will be destroyed by forest wind
"We believe that although the Black Panther diesel engine has improved the cylinder structure, there is still a problem of insufficient overall strength." The next day, when the meeting started again, some changes had occurred in the argument.
An engine expert put forward his point of view. If you want to reach 1,200 horsepower, or even reach 1,500 horsepower in the later stage, it requires a very high cylinder pressure.
The current 150 engine has a piston diameter not large after all. If you want to get enough power, you need to have stronger internal pressure. At this time, can the cylinder strength meet the requirements?
They took a skeptical attitude.
"Yes, we also think that it is possible to expand to 1,200 horsepower, but reaching 1,500 horsepower is probably not enough. You will encounter various problems in the future, and you will still reach a dead end at that time."
If tanks continue to develop, they will gradually increase their weight, which requires the continuous strengthening of the power system. At present, a 1500-horsepower engine is still rare, but it can be imagined that in ten or twenty years, the mainstream tank engines will definitely transition to the 1500-horsepower level.
Since the first machine factory is aiming at 1,500 horsepower, everyone has to pay attention to it. Is the body strength enough?
"Yes, German diesel engines have larger piston diameters. Since they all choose this way, they must have their own concerns. If we improve the existing engine, we may encounter problems."
"Everyone, how about working with the United States if we can't solve the problem ourselves? We have contacted the Ricardo Engine Institute in the United States, and we worked with them to transform and develop our 12150L tank engine, how about it?"
Since the door was opened, the relationship with the West has been very good, especially the United States. In recent years, the relationship between the two sides has been deepening, and domestic groups have organized inspection teams to visit the United States. After World War II, the United States' scientific and technological strength was the strongest, so if you ask them to cooperate and improve, it will definitely be easier to succeed.
Everyone is giving advice whenever you say and I say. Faced with today's scene, Qin Zhenhua couldn't help but sneer in his heart.
The wind direction has changed a little quickly, and it is clearly the rhythm of isolating the machine factory.
Yes, the habit of eating alone is not good for the first machine factory. The wood is so beautiful that it will be destroyed. If the first machine factory succeeds and compares the engine, many people will definitely be dissatisfied.
Moreover, their concerns are theoretically reasonable. After all, there has never been a engine of this level in China, and it is a matter of crossing the river by feeling the stones.
However, when I heard about cooperating with the United States, Qin Zhenhua couldn't help but speak out: "It's unreliable for foreigners to rely on foreigners. How can foreigners bring us advanced technology? If we cooperate with the United States to transform, the final outcome is that the United States will help us transform. We spend money to buy technology, etc., and it is impossible for us to learn anything else. Maybe I don't know about this, but I can still infer this."
Can't make it happen by yourself, and then put your hope on foreigners?
Wake up, how is this possible?
Qin Zhenhua has seen it very clearly when he went out these days. The technology of imported tank guns was 120 mm, and the people were only willing to give 105 mm, and the technology of imported engines was even more irresistible. The British agreed to give a prototype, but what happened? In the end, they said nonsense that it was sinking into the sea.
If you want the most advanced one, people will hide it.
The West wants to help us, but to make us truly strong, we still rely on ourselves and others, and we cannot rely on us!
Everyone spent the morning of the meeting in this way, but no one mentioned the engine project of the first machine factory.
And in the afternoon, the engine office finally threw out their plan.
"We are now relying on our own technology to survey and map and imitate the 8V331 engine, and have entered a dead end. However, for the development of our domestic engine technology, we can only grit our teeth and continue to import technology from abroad. I suggest that the state invest and buy German technology."
The person who spoke was Wu Liquan, the director of the Engine Institute, who finally spoke. Even though he was reporting on his work yesterday, he was introduced to Xiang Dayang. Today, the director finally started their plan.
Since our surveying and mapping imitation cannot be done, just buy it!
Hearing this, Qin Zhenhua was speechless, holding his water cup tightly, almost crushing it.
Buy, buy, buy! Can you buy modern national defense by buying?
However, he still couldn't get into such a thing.
"If we don't ask for help from the outside world, then the research and development over the past few years has been completely wasted, and we have consumed a lot of national resources. Therefore, we have no other choice now. We can only continue to move forward firmly until the day of success!"
If you don’t buy it, your previous investment will be wasted. What if you buy it? After buying it, can you guarantee success? It’s ridiculous! Will people sell real technology?
Qin Zhenhua was already a little annoyed at this time, but he still remained calm and restrained.
"We just learned that MTU has continued to develop its 8V331 diesel engine based on its 8V331 diesel engine and has created the latest model called the 396 series engine."
Like the 331 diesel engine, this type of diesel engine is water-cooled, four-stroke, intercooled supercharged, and direct injection engine. Its technology is leading in Europe and the world. The cylinder diameter is still 165 mm, but the piston stroke has increased to 185 mm.\n
As a series of engines, it is divided into 6, 8, 12, l6 cylinders, V-shaped structure, with an angle of 90 degrees. Through different cylinder counts and oil breakage control, the power can be between 345 and 1920 kilowatts. Later improved models can even reach a terrible power output of 3,000 kilowatts.
"It has new technologies such as cylinder oil discharge, cylinder charge conversion, sequential turbocharger, electronic speed regulator, metal plate cooler, three-layer wall cooling exhaust system, etc. These technologies are currently lacking in our country. Therefore, after introduction, this engine can be widely used in various ships, large-tonnage mining dump trucks, oilfield mechanical power, railway locomotives, construction machinery, power generation equipment, special vehicle power, etc. Therefore, after introduction, it can be regarded as a military-civilian diesel engine, which contributes the greatest strength to the national economic development and military construction."
This diesel engine is not just a technical reserve for tank engines. It can be used from warships to generators! This vision and positioning are quite high-end.
