What is the purpose of adding a turbocharger to a car?
The purpose of a turbocharger is to increase the power of an engine by increasing its air intake without changing the engine structure.
The turbocharger is very simple, it is a blower that pumps air into the cylinder, turning the engine's natural intake into a forced intake and increasing the engine's air intake. The turbocharger in diesel cars is driven by exhaust gas from the exhaust pipe, while in petrol cars it is generally belt driven.
The role of car turbocharging is to increase the pressure of the intake air, so that the density of the intake air is increased, the intake air is correspondingly increased, so that more fuel can be burned to improve the power of the engine, and now car engines generally use exhaust gas turbochargers, driven by the engine's exhaust turbine rotation, driving the compressor work, the compressor to the intake pipe filled with pressurised air, the advantage is not more waste of engine power However, there is a lag, and it takes a short time for power to break out when the throttle is depressed. There is also a mechanical turbine driven by the crankshaft, which has the advantage of no lag, but at high revs it is not as effective and wastes a little engine power.
