There are five types of turbocharging for automotive engines:

1. Supercharger: It is installed on the engine and connected with the engine crankshaft by a belt. Power is obtained from the engine output shaft to drive the turbocharger rotor to rotate, so as to boost air into the intake manifold;

2. Turbocharger: Actually, it is an air compressor that uses the exhaust gas discharged by the engine as power to drive the turbine inside the turbine chamber (located in the exhaust duct). The turbine drives a coaxial impeller located in the intake duct, which compresses the fresh air sent by the air filter pipeline and then sends it into the cylinder;

3. Inertia turbocharger: uses the inertia impulse of exhaust gas discharged by the engine to push the turbine inside the turbine chamber. The turbine drives a coaxial impeller, which compresses and transports air from the air filter pipeline, causing it to be pressurized before entering the cylinder;

4. Air wave supercharger: uses the pulse of high-pressure exhaust gas to force air to compress. This system has good turbocharging performance and acceleration; However, the disadvantage is that the entire device is relatively bulky and not suitable for installation in smaller cars;

5. Stamping turbocharger: an integrated stamping structure that utilizes twin screws to directly press the intake air into the cylinder, without too many intermediate links. It has a strong low torque effect and very little power loss, which has unique advantages compared to other turbocharging methods.

At present, the turbocharging technology for automotive engines has a history of over 100 years and is considered a very mature technology.
