In this paper, simulation of a light duty direct injection diesel engine using a three dimensional numerical method is presented in order to analyze flow characteristics, injection, and combustion phenomenon. A solid model is constructed after analyzing the specification of the subject engine, and moving meshes are generated for various crank angles. Flow fields of the combustion chamber generated at the intake stroke are analyzed, and the behavior of swirl and tumble is studied. Heat flow characteristics of the diesel engine is also studied through analyzing injection and combustion considering chemical reaction. The result is used to analyze temperature, velocity, pressure, and exhaust gas component of the combustion chamber.
