"Our engine..."Hearing Qin Zhenhua's question, Zhang Baolin shook his head with helplessness in his eyes and a wry smile on his face.

"What's wrong?"

"It's exactly the same as what you said!" Zhang Baolin said.

The domestic engine is currently moving towards the threshold of 1,000 horsepower, and they have taken the lead in developing a 537 kilowatt engine, which is now a 730 horsepower diesel engine, which is quite exciting, and decided to break through to a higher goal first.

Just after the meeting, within a year, they tinkered with the new engine, put it on the bench, tested it, and the power reached the standard.

706 kilowatts, it is simply a benchmark for domestic diesel engines, but then, countless nightmares have come.

Any engine, not dragged onto the bench, get the experimental data, can be declared successful, it must withstand rigorous long-term testing, must have a high enough stability.

It's like a certain car manufacturer in later generations, which has always claimed that it is positive research and development, boasting about how advanced its engine technology is, how high the thermal efficiency is, and blowing more, and it is estimated that it is believed, and it has fooled a lot of fans, but how many years have it been boasting, it has been boasting, and it has never been actually loaded. And while they are boasting, other obscure car factories have already installed their own engines on the car and put it on the market.

Just making a data in the lab is actually very simple, but to really use it, it must be reliable! A small problem with any one component can have catastrophic consequences.

When they developed the 730 horsepower engine, they encountered such a situation, and it was quickly assembled, but after it was installed, large and small failures continued, and it took more than ten years to finally solve all the faults.

And now, the new engine began to be tested, and all sorts of failures popped up again.

"Burst cylinder head?" Qin Zhenhua asked.

"Yes, the cylinder head, this failure, has been bothering us for nearly two years, we have tried a variety of schemes, materials, processes, structures, processing, but, no matter how you try, it will always be a burst cylinder head." When Zhang Baolin spoke, his voice was very low.

At the beginning, when it was increased to 730 horsepower, they encountered this problem, bursting the cylinder head! After repeated research and various methods, the problem of bursting cylinder head was finally solved.

However, now as the power continues to increase, the problem of bursting the cylinder head has reappeared.

How to fix it?

Zhang Baolin has no confidence, because Qin Zhenhua said at the beginning that this problem will inevitably appear, using the original structure, the distance between the cylinder center is too small, unable to achieve enough heat dissipation effect, all gathered on the cylinder head, and the final burst of the cylinder head was formed.

How to fix it?

Thickening and strengthening the strength are useless, you can only increase the heart distance of the cylinder.

If the cylinder core distance is increased, isn't that the plan of a machine factory?

If you don't hit the south wall, you won't look back, but now that you hit the wall, what are they going to do? Keep going, expecting a sudden miracle to solve the problem?

Even if it can be solved, so what? Then when it reaches 1000 horsepower, it will come to an end, and the power of the tank engine, 1,000 horsepower is just a watershed, they still need to continue to improve.

The potential of the existing 12150L engine has been tapped, and it is even more difficult to improve it again.

"Stick to the wrong path, the farther you go, the farther you go, the farther you can only get to success." Qin Zhenhua said: "Zhang Gong, I invite you very sincerely, how about it?" Come to our machine factory, we are really in dire need of manpower now. ”

Wu Ruihua and others are also skilled and experienced, but there are too many tasks at hand, and Wu Ruihua has become the factory director again, and now, he is a busy man, running around.

If Zhang Baolin comes, he can be the person in charge of the new engine here.

Of course, Zhang Baolin will never agree to his proposal.

"Zhenhua, if you say that again, it will be to drive me away." Zhang Baolin said.

Qin Zhenhua had no choice but to shut up, and then thought of something: "Your R&D ability is actually still very strong, since you can get so much horsepower on the bench, it shows that the research and development of the supercharged intercooler is still good." ”

How do you squeeze the potential of your engine? It's a technical job.

The first application is the supercharger, as long as it is in the same cylinder, blowing more air into it, there has been a so-called car repair for many years of the master, saying that the supercharged engine is not reliable, the natural aspiration of the rudder surface is stable. In fact, they are just two knives, in the period of World War II, supercharger technology has been widely used, at that time it was mainly used in airplanes, the higher you fly, the thinner the air, the power of the engine will come down, so you can only use the supercharger to drum in more air to ensure that the power is not lost.

In order to reach higher altitudes, sometimes even in series, with two-stage superchargers, until the jet engine is used, finally it is not so complicated.

Then, transplanted to the ground, it is logical, many vehicles have begun to adopt, first of all, the diesel engine, drum in more air, spray more fuel, to increase power.

However, there is a limit to this, after the air is pressurized, it will heat up, and when the temperature is high, the density will decrease, so the turbocharging will not continue to increase to a certain extent.

What to do at this time? It's just to find a way to lower the temperature of the air, and when the air temperature is lower, more air can be blown in.

That is, a set of cooling devices is added to the air pipe of this turbocharger to form a supercharged intercooled structure.

For diesel engines, naturally aspirated is the first generation, turbocharging is the second generation, and supercharged intercooling, is the third generation, if you want to develop a high-horsepower diesel engine, supercharged intercooled is an inevitable trend.

They can achieve this kind of power, although it is unstable, but it always shows that the supercharged intercooling part is considered to be a successful development.

At present, we are still studying various technical data of a single cylinder, and have not yet touched on these fields.

"If you need it, we can provide the technology." Zhang Baolin said: "After all, this is for our new generation of tanks, and all our industry technicians should work together." ”

Qin Zhenhua was stunned for a moment, this is the consciousness of an old military worker, it is high!
