The function turbocharger is to improve the engine air intake, so as to improve the 

engine power and torque, so that the car more vigorous. An engine with a turbocharger 

can increase its power by 40 or more compared with an engine without a turbocharger. 

This means that the same engine can produce more power when it is supercharged.

Take our common 1.8τ turbocharged engine for example, after supercharging, the 

power can reach the level of 2.4L engine, but the fuel consumption is not much 

higher than 1.8 engine, in another level is to improve fuel economy and reduce 

exhaust emissions.

Turbocharger actuator price structure principle, exhaust gas turbocharger is mainly 

composed of pump wheel and turbine, of course, there are some other control 

components. The pump wheel and the turbine are connected by a shaft. The waste 

discharged from the engine drives the pump wheel, which drives the turbine to rotate, 

and the turbine turns to pressurize the input system. The supercharger is installed on 

the exhaust side of the engine, so the working temperature of the supercharger is very 

high, and the rotor speed of the supercharger is very high when the supercharger is 

working, so the turbocharger is generally adopted full floating bearing, lubrication by 

oil, and coolant for cooling of the supercharger.

In the past, turbochargers are mostly used in diesel engines, because gasoline and 

diesel combustion methods are not the same, so the engine with a turbocharger form 

is also different. Gasoline engine is different from diesel engine, it is not air into the 

cylinder, but the mixture of gasoline and air, too much pressure is easy to deignite. 

Therefore, the installation of turbochargers needs to avoid deflagration, which involves 

two related issues, one is high temperature control, the other is ignition time control.
