This document describes a student project to design an open cycle gas engine that uses a turbocharger. It is submitted by five students under the supervision of Mr. Bhupender Gahlot. The engine will run on LPG or CNG and power the turbocharger through exhaust gases, making it more efficient than traditional engines. It has several main components including an outer casing, flame chew, copper chew, and turbocharger. The fuel is ignited inside the flame chew and the hot gases spin the turbocharger before exiting.
