Science and technology have no borders, the person who said this sentence is justified, but the person who speaks only says the first half of the sentence, not the second half of the sentence, just like a good reading, not to understand much, many people will only say the first half of the sentence, I just read it, and I don't care if I understand it or not!

In fact, the content of the second half of the sentence is more important: every time I have a mind, I will happily forget to eat, I don't want to understand much, as long as I can gain, then I am very happy, being taken out of context, it is simply embarrassing for Tao Gong.

Science and technology have no borders, this sentence is actually just a prelude, in order to lead to the second half of the sentence: but scientists have their own motherland, the focus is on the second half of the sentence, but unfortunately, it is the same as not liking to read and prevaricating with not seeking a solution, the first half of the sentence is regarded as a righteous sentence.

Of course, Qin Zhenhua is mentioning it now, of course, for a purpose.

Will it be leaked? Of course not.

Just like the Germans are willing to export the 331 diesel engine and the 396 diesel engine to their own side, don't they know that they will disassemble and study it? Of course it will, but the Germans are not afraid, even if they take it apart and study, it is impossible to copy the diesel engine.

What's more, now that the other party is here, it is just the scene of the test run of the diesel engine for the other party to see, and the other party has seen the most that is the appearance, and it is impossible to take it apart and look inside, so there is no need to worry about leaking secrets.

On the other hand, let the other party see the appearance, and you can also let the other party know that your self-developed diesel engine has nothing to do with their diesel engine, and you have not copied their technology.

Because, the shape has already decided everything, although it is a V-shaped 12-cylinder structure, but the other party is an angle of 90 degrees, and the angle of their own is 60 degrees, the angle is different, and many characteristics are different, so this is destined to be two different diesel engines! (Every time a variety of information is introduced, it will be said that our engine is an imitation of the German diesel engine, East China Zhixiong really dare not agree, the basic structure is different, can it be said to be an imitation?) ）

The workshop for engine testing has been prepared, and a banner was specially hung on it today: Warmly celebrate the first ignition test of the Panther diesel engine!

Now, it is only the first test run, so there is no leader called, only one machine factory's own technical personnel, at the same time, Luo Ronggen and others have also come over, the big guy is standing in front of the engine test bench, talking enthusiastically.

In terms of appearance, it is a V-shaped engine, which is very similar to the 12150L engine, but because the core distance is larger, the whole engine looks longer, and the cylinder head is sprayed red, which looks more dazzling.

"Zhenhua, are you here? Engineer Mia, are you here too? Master Wu Ruihua, who was full of red light at this time, looked at the two people who came in.

"Well, this engine, it looks pretty good, how much horsepower do you expect to make?" Mia asked Uriva.

"When we designed it, we didn't go for too high a technical figure, so now we expect it to output about 1,000 horsepower."

A thousand horsepower! Hearing this data, Mia was intrigued: "So, at what speed?" ”

Talking about the power of the engine, we must talk about the speed, just like talking about the fuel consumption of the car without looking at the road conditions, it is meaningless.

"At the moment we are calibrated at 2,000 revolutions." Wu Ruihua said

"Two thousand revolutions, you can reach a thousand horsepower?" Mia was immediately surprised and said, "If the revs are increased to 2,400 rpm, wouldn't it be easy to achieve a power output of 1,200 horsepower?" ”

For a tank, 1,000 horsepower is a hurdle, 1,200 horsepower, 1,500 horsepower, and the other two hurdles, how to improve, the Germans took the way of increasing the speed, directly proportionally increased, and soon achieved a power output of 1,500 horsepower.

If the other party can reach 1,000 horsepower with only 2,000 rpm, it means that it should be easy to continue to improve.

"No, no, it's not easy." Wu Ruihua shook his head again and again: "If we use our own materials, it is still possible to increase the speed by two hundred revolutions, but on the premise of sacrificing life, it is almost impossible to increase the speed by four hundred revolutions, and it will definitely bring all kinds of unsolvable problems, and the 165 engine of our engine cannot be successfully developed, in fact, it is because the speed index is too high." ”

This is directly related to a country's industrial base.

The higher the engine speed, the higher the requirements for materials and processing, and the engine did come up with a copy of the 331 diesel engine, and the result? On the bench test, it can't meet the requirements at all, because the materials used are not up to standard, and the processing technology is not good.

The diesel engine in front of me, when it was designed, did not intend to take the road of increasing the speed, after all, the 12150L diesel engine, which is in the same vein, was originally only 2,000 rpm.

What is that? Of course, it is the advanced single-cylinder pre-research technology, in the past few years, the X150 engine of the coal provincial diesel engine factory has been on the bench in one year, and its own has not seen the appearance of the whole machine, in fact, it is because they are carrying out the pre-research of single-cylinder and the pre-research of each subsystem.

The internal combustion should be more sufficient, and there needs to be a high-quality piston that can carry high loads, and the bearings on the crankshaft are also newly developed, as for the turbocharger with a high boost ratio, the fuel injection pump with high pressure, etc., it is necessary to use more energy to develop it.

It can be said that these technologies are no worse than those of the Germans, and even in the research and development of cylinder partitions, they are more advanced than those of Germany.

"This is only theoretical, how much can actually be achieved, let's see how much it can be achieved first." Qin Zhenhua said.

"Yes, we're ready to start the engine today! Attention, tubing exhaust air! ”

The engine is brand new, today is the first test run, the lubricant has been installed, the diesel line has been opened, however, just start the engine, that is definitely not possible.

Gasoline car, if there is no fuel at all, you can start it with direct refueling, but the diesel engine is not good, if there is no oil, in addition to refueling, you also have to exhaust, and the oil pipe of the high-pressure oil pump can't start once there is air.

The hand oil pump was swishing, diesel was coming out of it, with bubbles, and the brand new engine was starting to be polluted by diesel for the first time.

"Attention, start the engine!" Everything was ready, Wu Ruihua gave the order, and Wang Erzhu was on the console side and twisted the start key.

"Wong, hum." The powerful starter drives the gear ring of the Panther diesel engine, and it rotates, and the crankshaft inside drives the connecting rod and piston, moving back and forth, and the four-stroke begins to circulate, and there is constantly diesel injection into the cylinder, and black smoke comes out of the exhaust pipe, through the pipe, directly out of the workshop.

The start of the engine was a little difficult, more and more relaxed, more and more relaxed, in the sound of the high-pressure oil pump pumping, the black smoke slowly lessened, and then, the engine finally made a cheerful sound.

Successful launch!
