My 1982

Jin Yuankun's old man recognized Li Zhongxin in the sleeper, the whole person seems to have a spirit.

Jin Yuankun has always had an idea that Li Zhongxin's legendary general figure. He didn't think that when he took the train, he met Li Zhongxin himself, and also chatted very happy.

Jin Yuankun has an emotion that China has no feelings in China. He always hopes to talk to Li Zhongxin to talk about the car.

Hongchao said a word, he still reminds this time, that is, the Chinese auto industry wants to develop rapidly. Li Zhongxin is a key person, and the loyalty company has money, and it has injected a lot of funds into automobile research and development. From the small parts of the car until the engine, there is basically a special researcher.

Especially in terms of engine, the intensity of loyalty is quite large, the machines and materials of the advanced countries, faithful companies can't lose, although it is not possible to say that China's domestic engine will definitely be a faithful research base to develop, but Absolutely there is such a possibility.

Jin Yuankun is clear, more than a hundred years of foreign industrial revolution, those developed countries have been in front, so that every process of automobile engines, every ingredient, every detail requires a little more accumulation Come out, it is from constant failure and slowly successfully.

Regardless of the advanced technology that looks like this, it is necessary to continue to study, and you must have successful failure. If you want to really have your own technology, there is no shortcut, you have to accept the failure of countless times, and you will be willing to accept .

In China, I want to get out of an engine that really belongs to China. It is necessary for countless researchers to study how many years of research works can be studied.

Those developed countries in foreign countries have passed a sentence, that is, science is shared, transparent and public.

Engineering is confidential, private, not to say who wants to open, not only engineering, many other research results are the same.

In Jin Yuankun, the principle of the engine can be said to be a simple, and this principle has never changed in 200 years in the internal combustion engine. In the words of direct white, it is nothing more than fuel burning gas expansion to push the piston.

But it is easy to say, it is difficult to do, in addition to those developed countries, other countries do not belong to their own automotive engine manufacturers at this time.

How to put power up, weight reduction, life expectancy, efficiency improvement can be said to be endless long.

Everyone can make it, but the engine, power and developed countries have no way, and there is no way to get to developed countries without the development of developed countries, the service life and stability.

Therefore, the research and production of the engine is definitely a very difficult thing in China.

And Ji Hongtu said that faith companies can withstand failure, can invest a lot of funds to do this, not only the top engine researcher in China is dug in the faith research base, but also dig some abroad Research staff, investment in this area is quite large, and after starting to set up this department, the number of money that is invested in is over 100 million yuan.

Others don't say, at this time, China's scientific research base can take out so much money to focus on the company, and they are mainly engaged, these people think that China's engine is afraid It is studying it, and it is also a big gap with the engine outside the country. This gap is not able to catch up in a few years.

Therefore, they would rather share with foreign car companies to bring foreign advanced engines, bringing those parts made from foreigners, and will not consider the money to study this aspect.

Although I can't say it, I can't say it, but it represents the idea of ​​most of China's car enterprises.

The most difficult place in the engine is the body's cylinder, which mostly uses metal castings, which are also divided into high-pressure casting and low pressure casting.

China's casting technology has a certain gap at this time and abroad, and the casting process is basically followed by some ancient operations, and modern high-tech things are rare.

After the metal enters the mold, the residual stress, exhaust gas, release agent spraying during the cooling temperature is reduced, and the defect has reduced the yield, and the life is severely affected because the metal fatigue is most afraid of defects.

This is a relatively large reason, in addition, the quality requirements of metal materials are also very high, generally cast iron or cast aluminum, high-quality casting raw materials, our domestic technology is still very backward.

Although China has conducted scientific and technological innovation in this respect, it has been improved and improved, but it is still a considerable gap between foreign countries.

Materials for aerospace technology are all national-level confidential things. The general enterprises are not such a technical and material, but it is only suitable for small scientific research. A large number of output is quite difficult. .

In addition, die-casting molds and die casting machines. At this time, the world's top machine is in Yide, and then it is Italy, then it is other.

The mold should be precise, durable, adapt to automatic production, can't be said to cast a few molds, leak, or only manually watch the Master the fire.

In China, general companies are intensive companies, and basically all the old employees have new employees, and the older generation has always had a church apprentice starry master, some good technologies and experiences. Often to death is not to give the apprentice, which is also a lot of development in China.

Like loyalty can buy high-quality lathe, grinding machine and boring machine, etc., it is a problem that you can use this high-quality lathe or grinding machine.

Moreover, there is such a problem that the engine produced is a large amount of production, and cannot be restricted by these things.

The piston is to be moved back and forth in the cylinder hole, and its error requires extremely high, and its wall surface processing requires a process called honing to ensure the surface of the cylinder hole and also attach one film to ensure sealing performance.

Honing if it is not good, the cylinder hole is afraid that the cylinder will accelerate the aging of the engine, so it is really difficult to engage in the horizontal engine.
