Which Is Better: a Supercharger or a Turbocharger?

by Starlight Generator dieselgeneratortech

The supercharger should refer to the engine intake supercharger and includes three forms: exhaust turbocharger, mechanical turbocharger, and electric assisted turbocharger. The air is compressed by the supercharger to increase the intake density of the engine, thereby increasing the power of the engine. At the same time, the engine's mixed combustion regulation is improved, the combustion efficiency is improved, and the fuel saving and emission reduction effects can be achieved.

A turbocharger is actually an air compressor that uses compressed air to increase the amount of intake air. It uses the inertial force of the exhaust gas from the engine to push the turbine in the turbine chamber. The turbine drives the coaxial impeller. The impeller presses the air sent by the air filter pipe to pressurize it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase, the impeller compresses more air into the cylinder, and the pressure and density of the air increase to burn more fuel, correspondingly increase the fuel amount and adjust the engine speed. It is possible to increase the output power of the engine.

If you are wondering which is better - it all depends on the vehicle.

Turbochargers are used most commonly for small engines such as those with four cylinders.

Superchargers deliver their power at lower RPMs and a turbocharger works best at high engine speeds.

Turbochargers are quieter

Superchargers are somewhat more reliable.

Superchargers are also easier to maintain than the more complex turbocharger system.
