Rebirth: From arcade game to business empire

HarmonyOS Group's fuel engine?

At this moment, all car companies have a feeling of not being able to sit still.

Who would have thought that this guy Lin Mu was really engaged in this fuel engine.

Moreover, looking at Lin Mu like this, it seems that he really got it, and... It must have had a certain effect, otherwise, Lin Mu would never have taken it out.

Kitaro Toyoda couldn't help but sit up straight.

Then, I saw four waiter ladies pushing this fuel engine in front of everyone.

"Now, please let me introduce, HarmonyOS Engine!" Lin Mu said slowly: "There is no doubt that this engine of mine is completely applied to the car!" "

"First of all, I can tell you that the engine of Hongmeng Group can fully achieve a high compression ratio of 13:1 using No. 92 standard gasoline!"

Then, Lin Mu raised a finger and said slowly: "The fuel economy is increased by 35%, and the torque in the medium and low speed range is increased by 25%, so that your car can be the perfect combination of acceleration and energy saving and environmental protection." "

Kitaro Toyoda couldn't help frowning.

First, the current Toyota technology, the gasoline engine compression ratio is generally between 8~10, theoretically when the compression ratio is increased from 10 to 15, the combustion efficiency can be improved by about 9%.

Despite this, Toyota wants to continue to expand its direction, and the improvement of the compression ratio of gasoline engines has almost stagnated over the years.

"Now, let me briefly introduce our technology, first of all, for the vast majority of engines, one of the reasons why the compression ratio cannot be improved is that the power output is greatly reduced due to detonation.

The so-called detonation refers to the detonation noise caused by abnormal combustion caused by automatic ignition before the normal combustion is completed when the mixture of fuel and air encounters high temperature and high pressure. When the compression ratio increases, the temperature near the dead center on the compression stroke increases, which is prone to detonation.

To reduce the temperature at the dead center on the compression stroke, it is necessary to reduce the amount of hot gases remaining in the combustion chamber. Residual gases have a significant effect on detonation. If the residual gas is reduced to 8%~4%, even if the compression ratio is increased by more than 3%. "

These words, to Matsushita Konosuke, are almost ambiguous, and they just don't understand what they mean, but Kitaro Toyoda and Soichiro Honda can't help but nod their heads frequently when they hear it.

Even if Konosuke Matsushita doesn't understand cars, he can see that Lin Mu's thing is probably not of ordinary quality.

"Our gasoline engines achieve ultra-high compression ratios by reducing residual gases." Lin Mu said that the main cause of the earthquake is residual gas, for which we specifically use the 4-2-1 exhaust system.

Ordinary vehicles will produce the phenomenon of exhaust gas reflux when exhausting, which will affect the temperature of the gas in the cylinder, which is easy to produce deflagration, and will also lead to the mixing of exhaust gas in the cylinder. In a 4-2-1 long-path exhaust system, it takes longer for high-pressure waves to reach other cylinders, and this detrimental effect is only present at very low speeds, reducing residual gas in almost the entire speed range. In addition, in order to increase the torque in the practical speed range, it is usually necessary to install a long exhaust pipe of more than 600 mm, but the coil-shaped exhaust pipe is used to save space. “

Toyota Kitaro and Honda Soichiro immediately glanced at each other, although what Lin Mu said was still very simple, but it was tantamount to giving them a new idea.

Lin Mu, this guy, is too powerful.

Everyone knows that the gasoline engine can be said to be the heart of a car, without the engine, it is a garbage, although Lin Mu did not produce a car, but with this engine, this is also a small earthquake for the automotive industry.

As for Lin Mu's technique, they are now beginning to be curious.

If they could, they would really like to take this engine apart and study it well.

Lin Mu introduced while looking at Mazda's Matsuda Hengji, this technology, in fact, 32 years later, Mazda's gasoline engine.

"At the same time, the shortened combustion time is another means of avoiding knocking, and the exposure time of the unmixed gas to high temperatures is also shortened, which facilitates the normal combustion before the detonation occurs. First of all, we have improved, the direct injection technology in the cylinder, which can enhance the air flow and increase the injection pressure, and secondly, the 6-hole high-pressure fuel injection: improve the injection performance, produce a more uniform and stronger flow of mixed gas, and finally the concave piston design: to avoid the fire in the initial stage of the fuel contact with the piston head, the combustion is more uniform! "

Lin Mu continued: "Of course, by precisely controlling the timing of the opening and closing of the intake and exhaust valves, the intake and exhaust efficiency can be maximized, and the engine performance can be improved, which has a more comprehensive and practical effect than turbocharging. At the same time, a lot of measures have been taken to improve friction loss, pump gas loss, and lightweight design! "

"That's how I said it!"

Lin Mu paused slightly, and then continued to speak: "Our gasoline combustion technology is far more than most engines on the market, taking Toyota as an example, his combustion efficiency is only 25%, and most of the energy of gasoline combustion cannot be transmitted to the wheels. “

"However, here, I can assure all of you that our Hongmeng high compression ratio gasoline engine is redesigned to solve the problems of insufficient combustion, engine wear resistance, internal pump wheel loss and other reasons, so as to maximize the combustion efficiency, at least more than 30%!"

Lin Mu's voice fell, but Kitaro Toyoda couldn't help but raise his palm: "Mr. Lin, is what you said true?" "

Don't think about it, if it's true, then, whoever uses this engine means that their market share will be greater, although they are all island people, but the competition between each other is still very fierce.

"Of course!" Lin Mu spread his hands, and then said lightly: "This point, if you are interested, you can wait a while, after a while, I can remove the Toyota engine, install our engine, and let him test it!" "

This kind of self-confidence made everyone can't help but be silent.

Lin Mu, this guy, is really terrifying.

It's just a devil.

If this is the Hongmeng Group's development of cars, it will simply be their biggest competitor.

Needless to say, this is a game-changing engine for the automotive industry!

Soichiro Honda couldn't help but speak: "So, Mr. Lin, are you going to sell this engine when you show it now?" "

Lin Mu had a smile on his face: "Sell!" "
