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

In an era when more and more attention is paid to energy conservation and emission reduction, especially when automobile exhaust pollutes the environment, European countries have begun to formulate strict emission standards year after year.

And Japan, because of its limited land resources, is closely following the pace of Europe. Although the United States does not have mandatory regulations in this regard, due to the rise in gasoline prices year after year, ordinary people have to choose more energy-saving and environmentally friendly ones.

Car models to prevent your wallet from shrinking.

As a result, the golden age of large-displacement cars is gradually moving into the past, while small-displacement cars are increasingly emerging.

As the displacement of the car decreases, it will face the problem of reduced power, reduced top speed, maximum output power, and reduced torque. As a result, major automakers, in order to reduce consumers' concerns in this regard, have begun to take turns

Work hard on your own engine.

For example, the TSI system engine that Volkswagen invested heavily in research and development, and Huayang Power's ecoboost engine were all born to solve this proposition.

It's just that the original ecoboost was not born in the hands of Ford until 2008, but now this engine was born a few years earlier, in the hands of Jin Xiaoqiang of Huayang Power.

Volkswagen's TSI technology is still operating according to its original historical trajectory.

Since 2000, Volkswagen has realized that as Japanese cars gradually become more competitive and they are facing increasing pressure in the market, they must launch a new generation of engine systems to compete with the competition.

The pressure on Japanese cars.

So from that time on, they began to develop TSI technology.

In the current automobile era, all automobile manufacturers know that if you want to use a smaller displacement engine, but you do not want to lose power, then you have to increase the compression ratio of air and fuel, which can effectively improve this

Regarding compression ratio technology, the most effective one is of course in-cylinder direct injection technology, followed by supercharging technology.

The principle of direct injection in the cylinder is to enable better atomization of gasoline. The principle of supercharging is to allow more air to enter the cylinder, thereby increasing the compression ratio.

Supercharging technology is also divided into two major schools, one is mechanical supercharging, and the other is turbocharging. Currently, the more mainstream one on the market is turbocharging, but mechanical supercharging is not without its merits. It also occupies a leading position.

a place in the market.

Supercharging technology was born many years earlier than turbocharging. Its principle is also very simple. In fact, it is equivalent to installing a blower on a car. The power of the car motor drives the compressor, allowing more air to flow with it.

When the motor operates, the cylinder and fuel are more fully combined to achieve the best combustion effect.

Its advantage is that the human-machine response is sensitive. As long as the motor is rotating, this supercharger can operate at any time and intervene in the operation of the engine to provide powerful power to the engine.

But the shortcomings are also obvious, because the rotation of the engine is required to provide energy to the supercharger, and when running at high speed, the rotor in this supercharger will also consume a lot of energy, so the economy is relatively poor.

And when the speed of the car increases and 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 it cannot compete with turbocharging. Supercharging can only perform well at low speeds, and its characteristic is that it allows the engine to burst out high torque at low speeds.

Turbocharging is completely different. We all know that the heat emitted by the engine is very high. One-third of this heat will do work in the cylinder, and another third will enter the condensation system, and the other

One-third will be discharged along with the exhaust gas.

As this part of the hot air is discharged, the available power is often as high as tens of kilowatts. Don't underestimate the power of these tens of kilowatts. Just these tens of kilowatts of power can allow two hundred electric fans to operate at the same time.

Times of Day.

The turbocharger takes advantage of the power of the exhaust gas and introduces the exhaust gas from the car into the turbine through a special exhaust pipe. While turning the turbine fan, it then drives the intake air of another car.

The turbine compresses the air and introduces the air into the cylinder so that the car can get a better compression ratio.

However, the shortcomings of the turbocharger are equally obvious, that is, due to the weight of the turbocharger, when the car is at low speed, that is, the starting stage, and the engine speed is insufficient, the exhaust volume is not enough to drive the turbine.

This is the so-called turbo lag effect.

Only when the engine speed reaches a certain level and the exhaust volume increases significantly, 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 at medium and high speeds. It has no performance at low speeds, or even does not work at all.

Take the ecoboost engine developed by Jin Xiaoqiang. Even though he used the new turbine developed by Americans a few years later and replaced the rotor inside, there was still a slight turbo lag. When the engine speed was low,

At 1300 rpm, the turbine will not intervene in the engine work 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 to be transplanted to the Yidong engine that he wants to upgrade.

Volkswagen's TSI concept perfectly integrates these two supercharging technologies.

That is to say, they put two superchargers on an engine. One is a supercharger, which is used when the engine just starts, and the other is a turbocharger, which is used when the engine speed reaches a certain level.

It will only intervene after reaching a certain level, and when the turbocharger intervenes, the supercharger will automatically disconnect and stop working.

This combination, coupled with Volkswagen's always-leading in-cylinder direct injection technology, really became popular all over 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, it also exploded into extremely powerful combat power in the following years, defeating the previously aggressive Japanese car manufacturers.

Originally, Volkswagen announced the TSI plan in 2003, and it was launched in Germany in 2004. However, it was still in the testing stage and had not been launched into the market on a large scale.

The real large-scale introduction to the market was in 2005.

In the past two years, Huayang Dynamics, led by Jin Xiaoqiang, suddenly emerged while Volkswagen and Japanese cars were fighting each other in various aspects, and the new technology field was in short supply.

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

The Japanese are not in a hurry. Their cars rely on the lightweight and fuel-saving characteristics of the body and the engine technology foundation laid in the 1990s. Technically, they are not in a declining stage. In the early stage, they seized a large number of

European and American markets, so they did not panic when faced with the challenge of Huayang Dynamics.

But Volkswagen is different. At present, their position in the global automobile market can really be said to be in jeopardy. Volkswagen's product series, not only in Europe but also in China, has no competitiveness at all in the world and Japanese car manufacturers.

In China, they could have won people's reputation by introducing some new technologies, but now that they have no advantage in technology compared to Huayang Dynamics, they have lost ground one after another.

This can be clearly seen from Huayang Power's rapid growth in sales this year and their shrinking sales.

Facing the challenge of Huayang Power, Japanese car manufacturers can blatantly cut prices to compete with Huayang Power. However, German cars cannot let go of their noble white face and superiority in their hearts, so now they can only face the market being suppressed.

The consequences of a squeeze.

Volkswagen is really anxious this year. Their TSI engine is on the verge of being fired.

Jin Xiaoqiang's plan is to give the public a severe blow on the TSI system that the public is most proud of.

The reason why he did this was because the people of Volkswagen are really useless. Their TSI dual-supercharged engine is indeed a good thing.

But these guys, when they buy this kind of engine from China, they will perform castration surgery and remove the supercharger part, but they will continue to fool everyone on the logo of the engine and model that it is a TSI engine.

, the one purchased is still more expensive.

In his previous life, Jin Xiaoqiang had seen many owners of popular Volkswagen cars complaining that their cars were not as good as they imagined before buying them. They had many minor problems, were expensive to maintain, and burned oil.

Although Volkswagen also has its own reasons for castrating the supercharger, the same cutting of corners in other materials makes Jin Xiaoqiang feel a little uncomfortable.

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

So if you want to stop them, there is only one way, and that is to fight them and come up with an engine similar to theirs to piss off the public.

Jin Xiaoqiang felt a little excited when he thought about the TSI that could snipe the public. Let them call themselves the magic vehicles and let them continue to deceive us people. This time I just want to make them look good and let them fall to the ground they lead.

I am proud of this TSI top! (To be continued)
