Technology has no borders. People say this sentence with confidence, but the speaker only says the first half and not the second half. It is like reading and not understanding it very much. Many people only know the first half. I can read it.
, don’t care whether you understand or not!
In fact, the content of the second half of the sentence is more important: whenever you understand, you will be happy to forget to eat. I don’t want to understand much. As long as you can gain something, you will be very happy. Being taken out of context makes Tao Gong ashamed.
Science and technology have no borders. This sentence is actually just a prelude to introduce the next half sentence: But scientists have their own motherland, and the focus is on the second half. Unfortunately, it is just like not liking to read and not seeking deep understanding.
I treat the first half as a righteous word.
Of course, Qin Zhenhua mentioned it now, of course it has a purpose.
Will it leak? Of course it is impossible.
Just like the Germans are willing to export the 331 diesel engine and the 396 diesel engine to our own side, don’t you know that we will disassemble and study it? Of course, it will, but the Germans are not afraid. Even if we disassemble and study it, it is impossible to give the diesel engine to our own side.
Imitated.
What's more, now we are just trying to see the diesel engine test scene. The other party sees the most, which is the appearance, and it is impossible to take it apart from the inside, so there is no need to worry about leaking the secrets at all.
On the other hand, letting the other party see the appearance can also let the other party know that the self-developed diesel engine of the side has nothing to do with their diesel engine, and the side has not copied their technology.
Because the appearance determines everything. Although it is a V-shaped 12 cylinder structure, the other party has an angle of 90 degrees, and the one on the side has an angle of 60 degrees. Different angles are different, so many characteristics are different. Therefore,
These are destined to be two different diesel engines! (Every time various information is introduced, we will say that our engine is imitating German diesel engines. The hero of East China really doesn't agree with it. The basic structures are different. Can it be said to be imitating?)
The engine test workshop is ready, and today I specially hung a banner on it: Warmly celebrate the first ignition test of the Black Panther diesel engine!
Now, it was only the first test run, so there were no leaders from the company, just the technicians of Yimai Factory. At the same time, Luo Ronggen and others also came over, and everyone stood on the engine test run stand.
In front of him, he was talking enthusiastically.
From the appearance, it is a V-shaped engine, which is very similar to the 12150L engine. However, because the cylinder center distance is larger, the entire engine looks longer, and the cylinder head is sprayed red, which looks even more
Dazzling.
"Zhenhua, are you here? Engineer Mia, are you here too?" Master Wu Ruihua looked at the two people coming in at this time.
"Well, this engine looks pretty good. How much horsepower do you expect to output?" Mia asked Urihua.
"When we designed it, we did not pursue too high technical data, so now we expect it to output about a thousand horsepower."
One thousand horsepower! After hearing this data, Mia was very interested: "So, at what speed is it?"
When talking about the power of the engine, you have to talk about the speed. It is just like talking about the fuel consumption of a car without looking at the road conditions. That makes no sense.
"We are currently calibrating at 2,000 revolutions." Wu Ruihua said
"Two thousand revolutions can reach one thousand horsepower?" Mia said in surprise: "If the speed is increased to two thousand four hundred revolutions, wouldn't it be possible to easily achieve a power output of one thousand two hundred horsepower?"
For a tank, one thousand horsepower is a hurdle, one thousand two hundred horsepower, one thousand five hundred horsepower, two other hurdles. How to improve, the Germans are taking the way to increase the speed, directly
By increasing proportionally, a power output of 1,500 horsepower was soon achieved.
If the other party can reach one thousand horsepower in just two thousand revolutions, it means that it should be easy to continue to improve.
"No, no, this is not easy." Wu Ruihua shook his head repeatedly: "If we use our own materials, it is still OK to increase the speed by 200 revolutions. It is only based on the premise of sacrificing life, the speed by 400 revolutions is almost no
If possible, it will definitely bring about various unsolvable problems. The 165 engine in our engine station was not successfully developed because of the high speed indicator."
This is directly related to a country's industrial foundation.
The higher the engine speed, the higher the requirements for materials and processing. The engine did create a copy of the 331 diesel engine. What was the result? After being tested on the bench, the requirements were not met at all, because the materials used were not
The processing technology is not good.
When designing the diesel engine, I didn't plan to increase the speed. After all, the 12150L diesel engine, which is the same as the same lineage, was only 2,000 rpm.
What is it relying on? Of course, it is advanced single-cylinder pre-research technology. In recent years, the X150 engine of the Coal Provincial Diesel Engine Factory has been on the bench in one year, and the whole machine has not yet appeared.
In fact, it is just because they are conducting single-cylinder pre-research and various subsystems.
The internal combustion is more sufficient, and high-quality pistons that can carry high loads are required. The bearing bushings on the crankshaft are also newly developed. As for turbochargers with high boost ratios, high-pressure fuel injection pumps, etc., it is even more so.
It takes more energy to develop.
It can be said that these technologies are not worse than those of the Germans. They are even more advanced in the research and development of cylinder partitions, etc., and combined with their own industrial foundation, what is best for them.
"This is only theoretical. In fact, we should take a look at how much it can be achieved first." Qin Zhenhua said.
"Yes, we are ready to start the engine today! Pay attention, the oil pipe exhausts air!"
The engine is brand new. Today is the first test run. The lubricant has been installed and the diesel pipeline has been opened. However, it is definitely not possible to start the engine directly.
If the gasoline car is completely out of oil, it can be fired by refueling directly, but the diesel engine cannot do it. If there is no oil, in addition to refueling, it also needs to be exhausted. Once the oil pipe in the high-pressure oil pump is airless, it cannot be started.
.
The hand oil pump was whistling, and diesel flowed out of it, with bubbles, and the brand new engine began to be contaminated by diesel for the first time.
"Be careful, start the engine!" Everything was ready, Wu Ruihua issued an order, and Wang Erzhu twisted the start key on the console.
"Wang, buzz." The powerful and powerful starter drove the ring gear of the Black Panther diesel engine and rotated. The crankshaft inside drove the connecting rod and piston, and then reciprocating back and forth. The four-strokes began to circulate, constantly with
Diesel is injected into the cylinder, and black smoke comes out of the exhaust pipe, and is directly exported outside the workshop through the pipe.
The engine started to start, which was a bit difficult, and became more and more relaxed. In the sound of the pumping oil of the dada high-pressure oil pump, the black smoke slowly eased, and then, the engine finally made a cheerful sound.
