The Difference Between Supercharging and Turbocharging

[DiAlina]

The differences between supercharging and turbocharging are as follows: 1. Supercharging utilizes the engine's own power to drive a compressor for pressurization, which consumes engine power. The speed changes with the engine speed, so there is no turbo lag. It performs exceptionally well at low engine speeds but is limited by the engine speed, resulting in insufficient pressurization at high engine speeds. 2. Turbocharging uses the exhaust gases produced by the engine to drive a turbine in the exhaust pipe, which in turn drives a turbine in the intake pipe for indirect pressurization, without consuming engine power. Turbochargers operate at extremely high speeds and provide several times more pressure than superchargers. However, due to the inertia of the turbine and the considerable resistance of the intermediate bearings, the turbine speed does not increase immediately when exhaust gases suddenly increase, which is known as turbo lag.
