What is a turbocharger

The engine relies on the fuel burning in the cylinder to form power, because the amount of fuel introduced will be limited by the amount of air absorbed into the cylinder, so the power formed by the engine will also be limited. If the operating performance index of the engine is in the optimal mode, the output power can only be increased by compressing a large amount of air into the cylinder to increase the fuel amount, and then improve the efficiency Engine power capability.

Turbo system is one of the most common turbocharging systems in turbocharged engines.

If in the same unit time, a large amount of air and fuel mixture can be forced into the cylinder (combustion chamber) to carry out compression combustion and explosion action (the engine with small exhaust volume can "suck in" the same air with large exhaust volume to improve volumetric efficiency), it can form a greater power output than the naturally aspirated engine at the same speed. The situation is just like you take a fan to blow into the cylinder, and force the air to flow in to increase the air volume inside, so as to get greater horsepower. However, the fan is not driven by an electric motor, but by the exhaust gas from the engine.

Generally speaking, the engine can increase the extra power by at least 30% - 40% after cooperating with such a "forced air intake" action. This amazing effect is the reason why people can't put it down. What's more, getting a good combustion efficiency and greatly improving the power is where the turbocharging system can give the maximum value to the vehicle.

How does the turbocharger work?

First, the exhaust gas from the engine pushes the turbine impeller at the exhaust end of the turbine and makes it rotate. Thus, the compressor impeller on the other side connected with it can be pushed to rotate together. Therefore, the compressor impeller can force the air from the air inlet, and after the rotation and compression of the blade, it will enter the compression channel with smaller and smaller diameter for re compression. The temperature of the compressed air will be higher than that of the direct suction, and it needs to be cooled by the intercooler before it is injected into the cylinder for combustion. This is how the turbocharger works.
