The next day, Zhou Jingming and Wang Yuanchao set off to the engine research institute in Gusu City.

The F1 engine currently being developed by Tianming Group is based on the V8 engine specially developed by Tianming Group for Yanhuang car, with a displacement of 3.0L, which is only equivalent to the displacement of ordinary medium and large cars, but the power generated is larger than that of an ordinary 8.0L ordinary engine.

If you want the kinetic energy generated by the engine to be large enough, there are generally two ways to do it, one is to increase the volume of the engine, so that the more cylinders of the engine, the better, a typical example is the giant truck running in the mine, a truck weighs more than 360 tons, the volume of his engine is much larger than the volume of the general car, and the displacement of the engine has reached 73L.

In the early days of F1 races, the number of cylinders in the engine used to reach 12 cylinders, but later the FIA changed the rules and gradually reduced the maximum number of cylinders in the F1 engine to 8 cylinders. Therefore, it is not realistic to increase the power of the engine by increasing the number of cylinders, after all, a F1 car is more than 700 kilograms in total, which is lighter than all cars, and the engine is too large, which will affect the lightweight of the whole vehicle.

Another way to increase kinetic energy is to increase the speed of the engine, and in the same amount of time, increasing the combustion rate of fuel can also increase kinetic energy. F1 engines do just that.

Because of the safety and fuel saving of ordinary family cars, the maximum safe speed of the engine is generally about 5,000 revolutions per minute and about 6,000 revolutions per minute, the average sports car can reach 7,000 revolutions per minute, and the top sports car can reach 9,000 revolutions per minute, or even more than 10,000 revolutions!

The Bugatti Veyron engine has a maximum speed of more than 10,000 rpm.

But compared to the F1 engine, Bugatti Veyron will also be overshadowed in front of him, the maximum speed of the engine of the formula car can reach 19,000 to 20,000 rpm per minute, ordinary engines simply cannot withstand such high speeds, even if the F1 engine strengthened by special materials, at such a high speed, the service life is also very short, the average F1 team, each season needs about four to five engines.

It is precisely because of such a high rev that the power generated by the 3.0-liter F1 engine is even higher than that of the 8.0-liter supercar engine.

However, because the safety of the car has decreased sharply due to high rpm, since 2014, the FIA has changed the rules of the event, stipulating that the maximum speed of the engine shall not exceed 15,000 rpm, but the average driver will not use such a high speed of 15,000 rpm, when the engine speed reaches about 11,000 rpm, the driver will switch to a higher gear.

"This engine is internally named TMF1, which is the meaning of Tianming F1 engine, which contains a total of five units, internal combustion engine, kinetic energy recovery unit, heat recovery unit and energy reserve and ECU, our engine research institute is mainly responsible for the research and development of internal combustion engines, and the remaining four units, because they involve electronics, are mainly handed over to automotive electronics companies for development. ”

After entering the research institute, Wang Yuanchao introduced while taking Zhou Jingming to visit the laboratory of the F1 engine.

"What about the materials used?" Zhou Jingming asked as he listened.

"There are more than 20 alloys used in the whole engine, of which the main part of the engine is mainly titanium alloy, and the rest of the precision parts even use precious metals such as platinum and silver, our designers have compared, if the whole engine assembly is assembled, our TMF1 engine will be lighter than any team's engine. ”

Speaking of this, Wang Yuanchao's face couldn't help but show a look of pride. The outside world only knows that Tianming Group is entering the F1 World Championship for the first time, and is quite disdainful of Tianming Group becoming an F1 engine supplier, but they don't know that Tianming Group is making a fortune at this time.

Zhou Jingming also nodded appreciatively, lightweight is indeed very important for F1 cars, if the quality of the engine can be reduced, the use of carbon fiber materials on the body will also greatly reduce the mass, then the future Tianming team to participate in the car, the advantage will be greatly increased.

"In terms of noise control, has it been optimized?" Zhou Jingming continued. Because it revs at more than 10,000 rpm, the F1 engine produces a wave of 160 decibels at full speed, which is even louder than the Boeing 747 when it takes off.

Out of consideration for the health of the drivers, Zhou Jingming specifically requested that when designing the engine, the noise of the engine should be reduced as much as possible.

"This is still being studied, and it is planned to start from the two aspects of heat recovery units and materials, and the final results will not be known until they have been tested. Wang Yuanchao replied.

Immediately afterwards, Wang Yuanchao called the engineer in charge of the design of the internal combustion engine, and he gave Zhou Jingming a detailed introduction to the technical details. Although Zhou Jingming is not proficient in everything, he can understand every point, and sometimes Zhou Jingming can even argue with the other party about a certain technical detail.

"You just said that the angle of the engine, you use 108 degrees, have you considered changing the angle of the engine to 72 degrees, will this design have unexpected effects?" Zhou Jingming simply picked up the pen and drew on a piece of paper.

"The 72-degree corner design is not an internationally accepted design specification, and it is ...... Wait, if the turning angle is changed to 72 degrees, then the engine can provide more low-speed torque, so that it can not only ensure that the car has excellent cornering speed, but also maintain a relatively high tail speed, which perfectly solves the conflict between turning speed and tail speed!"

The engineer in charge of the design of the internal combustion engine was immediately excited, he didn't expect Zhou Jingming to solve the technical problems that had plagued him for so long at once, no wonder Zhou Jingming was able to serve as the CTO of Tianming Group!

"Chairman, thank you so much!" the engineer said excitedly.

Zhou Jingming smiled and waved his hand, "It's just a normal technical exchange, and I have a lot of questions I want to ask you." ”

Next, Zhou Jingming and the engineer had an in-depth discussion on the rest of the internal combustion engine. Zhou Jingming has not been involved in the field of technology in such a detailed manner for a long time, and this discussion has passed in an hour.

"If you have the time, consider adding a battery to the engine and developing our own hybrid engine. Zhou Jingming finally said.

"Hybrid engines, I saw them at Toyota earlier, but I haven't studied them carefully, and since the chairman said so, I will definitely study this F1 engine after the research is over. The engineer promised.

After spending more than half an hour to understand the research and development status of the Hongmeng engine, Zhou Jingming and Wang Yuanchao walked out.

"Jingming, you just mentioned the hybrid engine, do you want to use this kind of engine in a F1 car?" Wang Yuanchao asked curiously.

"Not only on the F1 car, all the models of our Tianming Group may use hybrid engines in the future, if you can, I hope you will prepare early, in addition to hybrid, pure electric vehicle technology, you can also learn about it in advance. Zhou Jingming replied with a smile.
