turbine wheel

The purpose of a turbocharger is to compress the air flowing into the diesel engine, this lets the engine squeeze more air into a cylinder and more air means that more fuel can be added. The engine burns air and fuel to create mechanical power, the more air and fuel it can burn the more powerful it is. In simple terms, a turbocharger comprises of a turbine and a compressor connected by a common shaft supported on a bearing system. The turbocharger converts waste energy from an engine's exhaust gases into compressed air, which it pushes into the engine. This allows the engine to burn more fuel producing more power and improve the overall efficiency of the combustion process.
