After Jin Yuankun's thoughts turned back, he asked seriously: "Chairman Li, I heard from Brother Ran Hongtu that Zhongxin Company has invested a lot in the research on engines, and now it has achieved some results. I take the liberty to ask, can Zhongxin Company unswervingly follow this path?"

Jin Yuankun feels that although some of the engines manufactured in China are made by themselves, they are other people's technology and are manufactured by foreigners.

Chinese people are just doing coolies, and their technology is made by others. Domestic engine technology is still in its infancy and is very poor, such as fuel consumption and noise.

Many so-called domestic cars have engines that are combined with the technology of others, and only some accessories are produced by themselves, so he asked the question he wanted to know the most.

"Of course, Zhongxin Company is a company with conscience and a very responsible company. Since it has begun to invest in the research on engine technology, it will do this to the end.

Only what is independently developed is the real technology of our country, the real thing, and can better serve our automobile industry and our people.

Our Zhongxin Research Base now has a technical achievement that has met the international engine standards and is even more than some ordinary car companies. I believe that it will take less than many years to develop our domestic engine technology.

Mr. Jin, if you have any technical talents in this area, you can recommend them to Zhongxin’s scientific research base.” Li Zhongxin said to Jin Yuankun with great certainty.

In this matter, Li Zhongxin is very sure that in major scientific research projects after the construction of the scientific research base, automobile engines are definitely one of them. He invested a lot of money in it because Li Zhongxin knew what domestic engines are like now.

The engine of a car is actually the heart of a car, providing power for the car's walking, and is related to the power, economy and environmental protection of the car. If the automobile industry wants to develop in the future, the engine is definitely the most critical thing and the most core technology.

Simply put, the engine is an energy conversion mechanism, that is, the thermal energy of gasoline (diesel) or natural gas is expanded by burning gas in the sealed cylinder, pushing the piston to perform work, and converting it into mechanical energy. This is the most basic principle of the engine.

All the structures of the engine serve energy conversion. The engine has been with the car for more than 100 years. It has greatly improved in design, manufacturing, process, performance, and control, but its basic principles have not changed.

Therefore, at this time, researchers at Zhongxin Research Base have continuously integrated the latest technology with the engine, turning the engine into a complex mechatronic product, so that the engine performance reaches the level of an international automotive engine.

Zhongxin Research Base already has a technology that is at the forefront of national automotive engines in terms of automotive engines, that is, the crankshaft flywheel set.

The main function of the crankshaft is to bear the force transmitted from the connecting rod and thus generate a rotational torque around its own axis, which is output to the outside through the flywheel; in addition, the crankshaft is also used to drive the engine's air distribution mechanism and generators, water pumps, steering oil pumps, air compressors and other accessories.

The crankshaft is one of the most important components of the engine and requires it to be made of materials with good strength, impact toughness and wear resistance. Zhongxin Company uses the medium carbon alloy steel die forged.

In order to improve the wear resistance of the crankshaft, the Zhongxin Research Base has high-frequency quenching or nitriding treatment and finally finished processing to achieve high accuracy and low surface roughness.

The crankshaft has sufficient stiffness and strength, good ability to withstand impact loads, wear resistance and good lubrication.

The flywheel is a disc with a large moment of inertia. Its main function is to store part of the kinetic energy input into the crankshaft during the work stroke, so as to overcome resistance in other strokes, drive the crank link mechanism to cross the upper dead center and lower dead center, ensure that the rotation angular velocity of the crankshaft and the output torque are as uniform as possible, and make it possible for the engine to overcome overloads in a short period of time.

The crankshaft flywheel set is mainly composed of crankshaft, flywheel, torsional shock absorber, pulley, timing gear, etc. The crankshaft flywheel set developed by Zhongxin Research Base at this time has passed the test, and it can be produced on a large scale in a period of one to two years.

This matter involves two key points, the most critical point is the material issue. The requirements for the materials used in this thing are very high. Many Chinese materials-producing companies do not meet the requirements of Zhongxin Scientific Research Base.

While building and producing this factory, we also need to research and develop high-quality materials and some very precise machines.

The machines and instruments of Zhongxin Research Base were all obtained by Li Zhongxin from developed countries, both in terms of price, accuracy, etc., and they are the most advanced in China. However, if large-scale production is required, how can such machines be obtained from abroad to China? In short, there are many problems.

Moreover, Ran Hongtu told Li Zhongxin that the scientific research base still lacks research talents in this area. If such a problem cannot be solved, the research speed will still be quite slow.

So, at this time, Li Zhongxin directly asked Jin Yuankun if he could help him find some scientific research talents in this area.

Li Zhongxin believes that Jin Yuankun is the deputy chief engineer of Jinbei Automobile and has always been in the automotive industry. His familiarity with industry personnel and experts is definitely greater than that of Ran Hongtu and other experts. If Jin Yuankun can help find some like-minded people to go to Zhongxin's scientific research base, it would be even more perfect.

Jin Yuankun looked at Li Zhongxin and smiled and said, "Chairman Li, you don't need to say anything about this. I will work hard to do it. What our country needs the most and what we old guys want to see the most is the ones we know the most. I will seriously consider this matter.

Have you seen this? This is my granddaughter Jin Ling, who came back from Ann Arbor, University of Michigan. This time I saw you, and I am ready to let my granddaughter join the engine project team of Zhongxin Research Base."
