Chapter 23 The Originator of Autonomous Engines
For anyone who understands cars and has played with cars, I am afraid they know the significance of Mitsubishi's EVO in modern coupes.
And for anyone who has been engaged in the automobile manufacturing industry in the Celestial Empire, I am afraid to understand the significance of the Mitsubishi EVO's 4G63 engine to the Celestial Empire Autobots.
As a person engaged in the automotive industry who has been engaged in automobiles for more than ten years in his previous life, Jin Xiaoqiang's understanding of this engine can be said to be like a treasure.
Regardless of the dispute between the system and the German system, this engine is really worthy of the classic two words, even if it is a Mercedes-Benz BMW, the engine in NB, for the people of the Celestial Empire, especially the influence of the car family, may not be able to beat this 4G63 engine.
Although the car companies in the Celestial Empire are very unkind, and the thin-skin cars they bought in the Celestial Empire are all reduced, although Jin Xiaoqiang also hates Yue himself.
But in terms of engine technology, Jin Xiaoqiang can't speak with a clear conscience, he has to admire his engine technology, and the most important thing is that in the transfer of engine technology, he is obviously much more generous than those noble Volkswagen 'god cars'.
You must know that for the car companies of the Celestial Empire's own brands, many manufacturers' engines start from imitating this 4G63 engine.
Because since 2000, private funds began to be opened up by the state to enter the field of automobile research and development, in the world, only Mitsubishi, which was not particularly backward in the world at that time, transferred this engine that was not particularly backward in the world at that time to the Aerospace Engine Research Institute in Nanyang City in the form of technology transfer.
And those so-called xxx cars, who have been mixed with the Germans for so many years, have helped the Germans pit so many yuan, but unfortunately after 2000, they can't even buy a complete set of Santana or Jetta engine technology, not to mention their own so-called research and development, not to mention, it's just a big joke......
It is the Nanyang Aerospace Engine Research Institute that introduced the 4G63 engine, which has become the originator of the engine research and development of many domestic cars.
I have to say that Mitsubishi's engine, especially the uniqueness of the engine with a small displacement, a 2.0 displacement engine can reach 280 horsepower, which is just through various minor changes.
If the ECU restriction is lifted, after some professional component modifications, this engine can easily output 400 horsepower, and even exceed 700 horsepower or even higher.
You must know such data, even in the 2010s, there are still many so-called latest engines, which have not yet reached such an output power.
Of course, the 4G63 engine that Mitsubishi exported to the Nanyang Aerospace Engine Research Institute is only a castrated version, and the 4G63 engine originally configured on the Mitsubishi EVO is a red-top engine with DOHC and VVT technology.
The 4G63, which was transferred to the Celestial Empire, was an ordinary civilian version of the engine that used SOH and did not have VVT technology.
The difference between the two is Mitsubishi's VVT technology, which claims to be MIVEC, and the difference between DOHC and SOHC.
Although this civilian version of the 4G63 and Mitsubishi's red-top 4D63 used on EVO cars have the above two differences, even this civilian version of the engine has brought a very big breakthrough to Tianchao Motors, especially to the automakers of their own brands.
One of the most important is that this engine has not been castrated, it originally came from the engine EFI system.
You must know that before the introduction of this engine, the automobile manufacturing industry of the Celestial Empire, especially those automobile manufacturers of their own brands, were still using mechanical carburetors when studying the engine.
However, the boss of the state-owned enterprise was not angry, and he cooperated with Volkswagen for 20 years, but he could not even ask for a set of professional engine technology from the foreign devils......
So it wasn't until the introduction of this 4G63 engine that the EFI technical problems on the Tianchao automobile engine were solved......
Later, many models of the so-called independent brands have not even changed, and this engine is used, such as Zunchi from Huazhong, Emgrand E8 from Liji, Ricky's Son of the East, and Great Wall's HX series......
Now what Jin Xiaoqiang sees on the computer screen is the drawing of the 4G63 engine drawn by Liu Xiaoliang, and it can be seen that Liu Xiaoliang still has considerable ability in modeling and drawing.
You must know that many domestic so-called engine design students, even if they enter the engine research and design unit, are basically just apprentices in the first year, that is, they follow the master to learn how to draw, if design, and calculate the power, but disassemble the engine, remember other people's things.
When it is really his turn to design by himself, it is generally necessary to wait for such an apprentice to enter the field of engines, and when he has three or five years of accumulation and has his own understanding of the engine, it is possible to design and develop an engine by himself.
However, now is basically not the time for a single person to engage in design, generally every R&D company has a dedicated R&D team.
Generally, an engine from design, to research and development, to the production of prototypes, after a variety of adjustment experiments, generally takes 36 months, or even longer to complete, and the first step is basically to draw and model on the computer.
This 4G63 engine was introduced by the Aerospace Engine Research Institute in Nanyang, and with such convenient conditions, Jin Xiaoqiang and his school, especially the automobile design major, also asked for a few engines from the aviation station.
When Jin Xiaoqiang and them were taught again, they were constantly disassembled, explained, and reassembled as living creatures, and it can be said that when Jin Xiaoqiang was in college, he did one of the few and meaningful experiments that he did, which was to disassemble and assemble this 4G63 engine.
In his last life, he was engaged in car design for almost five years, and finally he was reduced to repairing cars for others, and Jin Xiaoqiang was extremely familiar with this engine.
4-cylinder, 2.0 displacement, special stroke (88mm) larger than bore (85mm) design, liter power 140 hp, maximum power 280 hp, maximum torque 407N/m......
This engine can be called a classic for any Celestial Autobot.
In fact, what Jin Xiaoqiang wants to do with Liu Xiaoliang today is to replace the original 4G63 SOHC with DOHC, and plagiarize Honda's VTEC technology, after all, if you want to do VVT technology, Honda is the master.
Looking at the familiar engine drawings on the computer, Jin Xiaoqiang called Liu Xiaoliang to his side and explained it to him......
It turns out that this SOHC technology means that when there are more than two valves on the cylinder of the engine, the intake valve and the exhaust valve are mixed and arranged on a camshaft, so that when the engine works, because the valve can not be well controlled in different positions in the cylinder, the accuracy of the work is relatively poor, and the combustion ratio of the engine will not be very good, so it is more fuel-efficient.
And this DOHC technology, to put it bluntly, means that two camshafts are used on the engine, so that there will be no problems when the SOHC engine is running.
However, SOHC is relatively simple, easy to maintain, and cheap, but the manufacture of DOHC is more complex and the price cost is relatively high, but the mainstream trend of future engines is to use DOHC technology.
And what Jin Xiaoqiang wants to solve today is to draw this DOHC is drawing for Liu Xiaoliang, and this DOHC technology, at present, has always been a very critical shortage technology in the Celestial Empire, until seven or eight years later, when the Celestial Empire's own brand has a certain research and development capability, this technology was publicized.
When Jin Xiaoqiang drew the DOHC drawings to Liu Xiaoliang, Liu Xiaoliang was already shocked by Jin Xiaoqiang, you must know that the drawings drawn by Jin Xiaoqiang are still quite impactful for Liu Xiaoliang.
Don't look at it, it's just a change to the camshaft on the top of the engine, but how many people can't think of this alone, and even if they do, how many people can draw it like this?
And the most important thing is that when Jin Xiaoqiang was drawing, he explained various theories of DOHC to Liu Xiaoliang, although he had not been able to see the actual engine, but his theory alone had already made Liu Xiaoliang feel very convinced.
Jin Xiaoqiang and Liu Xiaoliang are constantly talking dialectically, and although Liu Mei on the side can't understand it, he can also see that these two people in front of him are really talented and learned, and the man at work is indeed the most attractive time.
At least Jin Xiaoqiang looked serious at this time, and he couldn't see the cynicism on his face when he was 'doing business' in the morning......
When the DOHC was done, the drawings were drawn, and after explaining all the technical theories to Liu Xiaoliang, Jin Xiaoqiang felt a little hungry, he raised his head to look, and then noticed that the sky outside had darkened at this time......
"Xiaoliang, or let's talk about the rest tomorrow......"
"Oops! What are you dragging? Isn't the rest a VVT technology? Let's just chase the poor man with the rest of the bravery, and we'll finish the assault tonight......"
Liu Xiaoliang is completely a technical maniac, at this time, for him, the whimsical ideas in Jin Xiaoqiang's brain are the ocean of knowledge, and he is now a dry sponge, so he has to fully absorb the knowledge in Jin Xiaoqiang's brain.
"Hey! All right! That one...... Liu Mei, can you go and get some food for a few of us? We guess we're going to have to work overtime tonight......"
