Study of air intake system of turbo charged diesel engines

This paper was to analyze the air intake system of turbo charged diesel engine. This was done by measuring the pressure drop across the air filter in the air intake system. Both static and dynamic measurements were conducted with the help of pressure measuring devices such as U — tube manometer and vacuum gauge. The point of measurement was at the tapping provided for restriction placed in between air filter and turbocharger compressor. Vehicles from various categories such as passenger vehicles, light commercial vehicles (LCV) and heavy commercial vehicles (HCV) were taken up and analyzed.
