Turbocharger Parts

Turbocharger Parts A turbocharger is an exhaust-gas driven forced induction device used in internal combustion engines to improve engine performance by forcing compressed air into the combustion chambers, allowing more fuel to be burned and resulting in a larger power output. A turbocharger consists of a turbine and a compressor linked by a shared axis. The turbine inlet receives exhaust gases from the engine exhaust manifold causing the turbine wheel to rotate. This rotation drives the compressor, compressing ambient air and delivering it to the air intake of the engine. The objective of a turbocharger is to improve upon the size-to-output efficiency of an engine by solving one of its cardinal limitations. A naturally aspirated engine uses only the downward stroke of a piston to create an area of low pressure in order to draw air into the cylinder. Since the number of air and fuel molecules determine the potential energy available to force the piston down on the combustion stroke and because of the relatively constant pressure of the atmosphere, there will ultimately be a limit to the amount of air and consequently fuel filling the combustion chamber.
Advantages of a turbocharger
more specific power over naturally aspirated engine
more power from same engine volume
more thermal efficiency over both naturally aspirated and supercharged engine
more mileage for same power output, due to the fall in the temperature of the exhaust gases in a turbocharger - thus energy saved is used to boost the intake
However, a turbocharger does load the engine by creating back pressure, but not as much as a superchargers mechanical drag.
