Important components of a Diesel Engine Turbocharger A turbocharger can significantly increase an engine’s horsepower without adding significant weight. It enhances engine performance by forcing more air into the combustion chamber, enabling better fuel combustion. A turbocharger is made up of two main sections: The turbine and the compressor.  The turbine consists of the turbine wheel and the turbine housing.  It is the job of the turbine housing to guide the exhaust gas into the turbine wheel. The energy from the exhaust gas turns the turbine wheel, and the gas then exits the turbine housing through an exhaust outlet area. The compressor also consists of two parts: the compressor wheel and the compressor housing.  The compressor’s mode of action is opposite that of the turbine. The compressor wheel is attached to the turbine by a forged steel shaft, and as the turbine turns the compressor wheel, the high-velocity spinning draws in air and c...

Turbocharger A turbocharger can significantly boost an engine's horsepower without significantly increasing its weight. It compresses the air flowing into the engine, allowing the engine to squeeze more air into a cylinder. More air means more fuel can be added, leading to increased power from each explosion in each cylinder. Crankcase The crankcase ventilation system is designed to maintain a balance between the engine crankcase air pressure and atmospheric pressure. Excessive pressure variations can negatively affect component life, the lubrication system, and overall engine emissions. Proper ventilation ensures optimal engine performance and longevity. Electronic Control Panel (ECP) The Electronic Control Panel (ECP) plays a crucial role in managing engine speed and fuel flow: A magnetic pickup sensor detects engine speed at the flywheel ring gear, generating an AC voltage proportional to the engine speed. The actuator controls fuel flow from the fuel pump to the inj...
