Both turbocharging and supercharging have their own shortcomings, but their advantages and disadvantages are exactly complementary. Volkswagen took advantage of the advantages, disadvantages and complementarity of these two supercharging systems to develop the TSI.

Dual booster system.

Their concept is to connect the supercharger and the turbocharger in series. After the air passes through the air filter, it first enters the supercharger, then is guided through the intake pipe, and then passes through the turbocharger.

regulator, and then the engine's intake manifold.

Although they are connected in series by the intake pipe, the two superchargers do not work at the same time.

When the engine is idling, the supercharger does not work. When the driver steps on the accelerator, the intake valve leading to the supercharger will open, and then the supercharger starts to work.

Moreover, at low speeds, the power loss of the engine from the supercharger is not large. After the vehicle speed increases, as the speed increases, when the speed reaches 1500 rpm, the turbocharger begins to intervene.

At this time, the two superchargers are working at the same time. At this time, the maximum pressure of supercharging can reach 2.5bar. When the engine speed exceeds 3500 rpm, his supercharger starts to stop working, leaving only

When the turbine is working, the boost pressure value will also drop to 1.3bar.

The working principle of the entire tsi can be used as a reference.

And this whole set of technologies will be particularly effective if installed on a small-displacement engine, but if it is replaced with a large-displacement engine, it is completely unnecessary.

Because those are two completely different concepts. Just imagine if a car owner who can afford to drive a model with a displacement of 3.0 or more would still care about such a small amount of fuel consumption?

But of course this is a foreigner. In China, people care about this very much, especially in China where oil prices have always been high in a few years. If engines with a displacement of 1.5 to 2.4 can be equipped with such technology, they will definitely be in the market.

is invincible.

This is exactly the type of engine that Jin Xiaoqiang plans to update for Eado.

But since we are also following the route of mechanical turbo dual supercharging, we have to take a different path from Volkswagen, lest Volkswagen accuse us of plagiarism.

So when Jin Xiaoqiang was considering his TSI engine belonging to Huayang Power, he had a headache for a long time.

After all, you can adopt the same idea as others, but you cannot be exactly the same as others in terms of details. [% High-Speed ​​Text First Station] Otherwise, the public will definitely have something to say.

And if it uses the same technology as other people's engines, this is not Jin Xiaoqiang's style.

If you want to defeat the public's TSI, you must do better than them, but where should you start?

After much deliberation, Jin Xiaoqiang almost lost his mind when he suddenly remembered an artifact, which was Eaton's TVS supercharger.

This supercharger is definitely an artifact!

The difference between a mechanical supercharger and a turbocharger is that its boost ratio is not good. The boost ratio of a general supercharger is around 0.6-1.2 bar, while the boost ratio of a turbocharger is okay.

It can easily reach 1.5bar, and even more powerful ones can reach around 2.5.

This is the main reason why a supercharger performs well at low speeds, but once the vehicle speed increases, its effect is obviously not as good as a turbocharger.

But such data became history with the sixth-generation TVS super supercharger developed by Eaton in 2008.

This supercharger is an intelligent supercharger. It can continuously adjust the boost ratio it can provide according to the engine speed. The limit of this supercharger is as high as 2.5bar.

Boost ratio.

This supercharger has become very popular since it was launched because it can provide an ultra-high pressure ratio, perform well at high engine speeds, and has no lag problem that occurs with turbochargers.

.

Therefore, as soon as this supercharger was launched on the market, it was immediately hailed as an artifact by the majority of automobile manufacturers, and was soon adopted by many luxury and high-end cars.

The Audi 3.0tfsi engine that was installed on the A6, A8, and Q7 and was selected as Ward's top ten engines from 2010 to 2012 was the super engine produced by Eaton.

Supercharger.

In high-end cars back then, Americans didn't even bother using superchargers. They only liked large-displacement engines. Even if they used superchargers, they only used superchargers.

The Japanese have always been more inclined to use more violent turbochargers, and the Germans followed suit. Audi took the lead in adding turbochargers to its high-end cars.

Originally, Mercedes-Benz was also playing with supercharging, but then seeing that Audi and the Japanese were doing so well, and that turbocharged cars were selling so well on the market, they started to play with turbocharging as well.

BMW originally wanted to install B and insisted on its own straight-6 engine, but then it turned out that the momentum was not good. It couldn't beat the Japanese and Mercedes-Benz without a turbine, so it also started to use turbocharging, so that many straight-6 engines

Fans are in vain.

Unexpectedly, in 2009, Audi suddenly made a comeback and started supercharging, and also used such an artifact produced by Eaton. As a result, it suddenly shocked BMW and Mercedes-Benz in the market.

Audi immediately took over a lot of territory.

Within a few years, Mercedes-Benz and BMW also began to install Eaton's artifact on their luxury and high-end models.

Now what Jin Xiaoqiang is thinking of is this Eaton TVS artifact, which is a good breaking point!

Why did Volkswagen later castrate the supercharger on the TSI engine it bought from China?

It's because their supercharger has to follow the engine to start running, and it can't stop until it reaches 3500 rpm, and it still uses a hard link, which means that when the engine starts working, even if it is mechanically supercharged,

The supercharger is not working yet, but it is also in a standby state, which will cause excessive losses to the supercharger.

Generally speaking, a supercharger needs to be replaced at 50,000 kilometers. The price of a supercharger is about 15,000 yuan. Who in China can afford such a later maintenance price?

?

This is also the main reason why the public later bought TSI engines from China, which were all castrated versions.

Moreover, the supercharger they use is Eaton's fifth-generation product, and there is still a big gap between it and Eaton's sixth-generation TVS.

The fifth-generation Eaton simplified supercharger used by Volkswagen still uses a three-blade rotor. It can only have a 60-degree twist angle, so the boost ratio it can provide is certainly not as good as that of the sixth-generation TVS.

Moreover, the maximum boost ratio that the supercharger can provide is only 1.2 bar, which is about half smaller than Eaton's sixth-generation TVS artifact.

The reason why Eaton's sixth-generation TVS is so awesome is entirely because it uses 4 blade-shaped rotors, and its maximum twist angle can reach 160 degrees. This is also the main reason why it can provide a boost ratio of 2.5.

reason.

And it also adopts a lot of new designs. For example, new air intake slots, new shell materials, and new rotor materials. It is a sealed integrated design and is maintenance-free for life. The service life is as high as more than 240,000 kilometers.

.

In terms of noise reduction, it is even more outstanding. Because it uses a four-blade rotor and a double-vortex structure, it has naturally low noise characteristics in its structure.

And it can do it. The engine is characterized by low loss when it is not supercharged. When the car is cruising at a high speed of more than 80 kilometers, the loss of this supercharger is actually less than 0.3 kilowatts.

How can a supercharger with such impressive data not be called an artifact?

Putting aside everything else, as long as you use such a supercharger on your Huayang Power TSI engine, you can completely beat Volkswagen's TSI.

You must know that it is mainly because of the supercharger that Volkswagen's TSI engine has been making noise but not raining since its launch.

Not only do people in China buy castrated versions, but even in the United States, they also buy castrated versions.

As for the complementary design theories of mechanical supercharging and turbocharging, only Volkswagen has tried such a dual-supercharging engine. No other major automobile manufacturer has adopted such a dual-supercharging mode because of the lack of mechanical supercharging.

The pressure regulator is not good enough here.

Now Jin Xiaoqiang is trying to make a breakthrough here, and if he can conquer this sixth-generation TVS artifact produced by Eaton, he will also have a better choice in terms of engine superchargers in the future.

Because according to research, this supercharger will perform better when equipped with large-displacement models. This is also the main reason why so many luxury cars later chose this supercharger.

Mercedes-Benz, BMW's Mini, Ford's Mustang, Jaguar and other well-known brands are all beneficiaries of this supercharger.

And if I conquer such a supercharger, I can make a lot of money just by buying this supercharger in the future.

This is the strongest piece of the jigsaw puzzle that belongs to our Huayang Dynamics TSI!

Jin Xiaoqiang just did it. He had an idea in his mind and started to work immediately. This Eaton tvs supercharger is an old friend of his. He thinks of the Audi a6l and Audi a8 of those rich people back then.

Or Q7, he has never touched it less.

He has dismantled a lot of this supercharger, so he knows the size and layout of the parts inside clearly. Moreover, he has also started the smelting process of the parts in this supercharger from the original ones.

I learned about it in car magazines and on the websites of automotive engineers that were posted on the Internet.

So now he starts plagiarizing, but he is familiar with the road. Within a few days, the blueprint of this supercharger was formed on his computer. (To be continued)
