To be honest, Volkswagen's TSI concept, in Jin Xiaoqiang's opinion, is still very good.

In the era of paying more and more attention to energy conservation and emission reduction, especially the era of environmental pollution caused by automobile exhaust, European countries have now begun to formulate strict emission standards year after year.

Japan, because of its limited land resources, is keeping up with the pace of Europe, and although the United States has not yet had mandatory regulations in this regard, because of the rising price of gasoline year after year, ordinary people have to choose more energy-saving and environmentally friendly models to prevent their wallets from shrinking.

In this way, the golden age of large-displacement cars is gradually moving towards the past, while small-displacement cars are on the rise.

The displacement of the car is small, then it is faced with the problem of power reduction, maximum speed and maximum output power and torque reduction, so that major car manufacturers, in order to reduce consumer concerns about this aspect, began to take turns to work on their own engines.

FOR EXAMPLE, THE TSI SYSTEM ENGINE DEVELOPED BY VOLKSWAGEN WITH HUGE INVESTMENT, AS WELL AS THE ECOBOOST ENGINE OF HUAYANG POWER, WERE BORN TO CRACK THIS PROPOSITION.

It's just that the original ECOBOOST was born in the hands of Ford in 08, and now this engine was born in the hands of Jin Xiaoqiang of Huayang Power a few years in advance.

Volkswagen's TSI technology is still running according to the original historical trajectory.

Since 2000, Volkswagen has realized that as Japanese cars become more competitive, they must introduce a new generation of engine systems to counter the pressure of Japanese cars as they become more and more competitive in the market.

That's when they started working on TSI technology.

In the current automobile era, all car manufacturers know that if you want to use a smaller displacement engine, but you don't want to lose power, then you need to increase the compression ratio of air and fuel, and the technology that can effectively improve this compression ratio is, of course, the most effective technology is direct injection technology, and then supercharging technology.

The principle of direct injection in the cylinder is to make the gasoline better atomized, and the principle of pressurization is to allow more air to enter the cylinder, so as to improve the compression ratio.

The supercharging technology is also divided into two schools, one is mechanical supercharging and the other is turbocharging, the more mainstream on the market is turbocharging, but mechanical supercharging is not useless, he also occupies a place in the market.

The birth of mechanical supercharging technology is many years earlier than turbocharging, and his principle is also very simple, in fact, it is equivalent to installing a blower on the car, with the power of the automobile motor, driving the compressor, so that more air can enter the cylinder and fuel with the operation of the motor, so as to achieve the best combustion effect.

His advantage is that the man-machine response is sensitive, as long as the motor is rotating, then this supercharger can operate at any time, and intervene in the operation of the engine, to provide strong power to the engine.

However, the disadvantage is also obvious, because the rotation of the engine is needed to provide energy to the supercharger, and when running at high speed, the rotor in the supercharger will also consume a lot of energy, so the economy is relatively poor.

And when the speed of the car is raised, the speed exceeds 3500 rpm, the performance of this supercharger is not so obvious, but it will consume a lot of fuel.

This is also the main reason why he can't compete with turbocharging, which can only perform well at low revs, and his characteristic is that he can make the engine burst out of high torque at low revs.

Turbocharging, on the other hand, is completely different, we all know that the engine is capable of emitting a lot of heat, a third of this heat will be done in the cylinders, another third will go into the condensing system, and the other third will be discharged with the exhaust gases.

As this part of the heat is discharged, the available power is often as high as more than ten kilowatts, but don't underestimate the power of these ten kilowatts, just these ten kilowatts of power can make 200 electric fans run at the same time for a day.

The turbocharger just uses the power of the exhaust gas, through a special exhaust pipe, the exhaust gas discharged by the car is introduced into the turbine, and at the same time rotating the fan of the turbine, it then drives the intake turbine of another car to compress the air, and the air is bowed into the cylinder, so that the car can get a better compression ratio. …,

However, the disadvantage of the turbocharger is also obvious, that is, because of the weight of the turbocharger, when the car is in the low speed that is, when the starting stage, when the engine speed is insufficient, the displacement is not enough to drive the turbo, which is the so-called turbo hysteresis effect.

Only when the speed of the engine reaches a certain degree and the displacement volume increases greatly, the turbine will be driven by the exhaust gas to achieve the purpose of rotating and intervening in the engine work.

Therefore, this supercharging method is not perfect, turbocharging can only perform well when the engine is in medium and high speeds, and at low speeds he does not perform at all, or even does not work at all.

FOR EXAMPLE, EVEN IF HE USED THE NEW TURBINE DEVELOPED BY THE AMERICANS A FEW YEARS LATER AND REPLACED THE ROTOR INSIDE, THERE WILL STILL BE A SLIGHT TURBO LAG, AND WHEN THE ENGINE SPEED IS LOWER THAN 3100 RPM, THE TURBO WILL NOT INTERVENE IN THE ENGINE AT ALL.

Moreover, because of the material of the rotor and the problem of finishing, the cost of that turbine is relatively high, so it is not suitable for transplantation to the Yidong engine that he wants to update.

Volkswagen's TSI concept is a good integration of these two supercharging technologies.

That is to say, they hit two superchargers on one engine, one is a supercharger, which is used when the engine is just starting, and the other is a turbocharger, which will intervene after the engine speed reaches a certain level, and when the turbocharger intervenes in the work, the supercharger will automatically disconnect and stop working.

Such a combination, coupled with the direct injection technology in the cylinder that Volkswagen has always dominated, has really swept the world after it was launched on the market.

Not only did it help Volkswagen stabilize its decline in the automobile market in one fell swoop, but also in the following years, it broke out with extremely strong combat effectiveness, beating the Japanese car dealers who were still aggressive before.

Originally, when Volkswagen was in his last life, it announced the TSI plan in 2003, and in 04, in Germany, but it was also in the testing stage and did not launch it on a large scale.

It was in 2005 that it was introduced to the market on a large scale.

In the past two years, Huayang Power led by Jin Xiaoqiang has suddenly killed when Volkswagen and Japanese cars are fighting in all aspects, and the new technology field is in full swing

And when it appeared, it occupied some technical commanding heights, which made Volkswagen and many Japanese car dealers feel very passive.

The Japanese are not in a hurry, their cars rely on the characteristics of lightweight and fuel-saving bodies, as well as the engine technology foundation laid in the nineties, and they are not in the stage of decline in technology, and they have seized the European and American markets on a large scale in the early stage, so they are not panicked when facing the challenge of Huayang Power.

But Volkswagen is different, at present, they are in the global car market, it can really be said that their position is in jeopardy, Volkswagen's product line, out of Europe and the Celestial Empire, around the world and Japanese car dealers have no competition at all.

In the Celestial Empire, they were able to rely on the bow to enter some new technologies to win people's reputation, but now in the face of the fact that the technology is completely undominant in Huayang Power, they have lost ground repeatedly.

This can be seen from the rapid growth of Huayang Power's sales this year, and their shrinking sales.

Japanese car dealers are facing the challenge of Huayang Power, and they can blatantly reduce prices and confront Huayang Power, but German cars can't let go of their noble white face, and the kind of superior Qing Gao in their bones, so now they can only face the end of being squeezed by the market.

This year's Volkswagen is really in a hurry, and their TSI engine is already ready to fly.

And Jin Xiaoqiang's plan is to give the public a hard blow on the TSI system, which the public is most proud of.

The reason why he did this is also because the Volkswagen gang is really not a thing, and their TSI twin-supercharged engine is really a good thing to say.

But these guys, when they buy this kind of engine to the Celestial Empire, they will carry out castration surgery to remove the supercharged part, but on the logo of the engine and model, they continue to fool everyone that this is a TSI engine, and the price is still more expensive.

In his last life, Jin Xiaoqiang saw a lot of owners of Volkswagen cars, all complaining that their cars were not as good as they imagined before they bought them, with many small problems, expensive maintenance, and burning engine oil.

Although Volkswagen also has their own reasons for castrating the supercharger, in terms of other materials, they also cut corners, which makes Jin Xiaoqiang feel a little unacceptable.

They are completely overdrawing their credibility in the Celestial Empire and fooling the people of the Celestial Empire, so in this life, Jin Xiaoqiang will never allow them to do this.

So if you want to stop them, there is only one way, and that is to fight against them and make an engine similar to them to anger the public.

At the thought of being able to snipe at the TSI of the public, Jin Xiaoqiang felt a little excited, let them claim to be a god car, let them continue to fool us people, this time the boss just wants to make them look good, let them fall on this TSI that they are proud of!. ）
