Turbochargers are essentially air compressors designed to increase intake air volume by compressing it. They harness the inertia of exhaust gases expelled by the engine to spin a turbine within the turbocharger housing, which in turn drives a coaxial compressor wheel. This compressor wheel pressurizes air supplied through the air filter, forcing it into the cylinders under increased pressure. As engine RPM rises, the exhaust velocity and turbine speed increase synchronously, enabling the compressor to force more air into the cylinders. The resultant increase in air pressure and density allows for the combustion of more fuel, thereby boosting engine output power by adjusting fuel quantity and engine RPM accordingly. Turbochargers enhance engine power by utilizing exhaust energy.
The working principle of an automobile muffler is primarily based on the principles of acoustic interference and energy absorption to reduce the noise generated by the engine during vehicle operation.
