What are the types of engine turbocharging?

[GiaLynn]

There are several types of engine turbocharging: 1. Mechanical supercharging system: Installed on the engine and connected to the engine crankshaft via a belt, it derives power from the engine output shaft to drive the supercharger's rotor, thereby pressurizing air into the intake manifold; 2. Pressure wave supercharging system: Utilizes the pulse pressure waves of high-pressure exhaust gases to force air compression, offering excellent supercharging and acceleration performance, but the entire setup is relatively bulky and less suitable for installation in smaller vehicles; 3. Exhaust gas turbocharging system: The turbocharger has no mechanical connection with the engine and essentially functions as an air compressor, increasing air intake by compressing air; 4. Compound supercharging system: Combines exhaust gas turbocharging and mechanical supercharging, where mechanical supercharging aids torque output at low speeds but has limited power output at high speeds, while exhaust gas turbocharging delivers strong power output at high speeds.
