摘要：D.I. Diesel engines are the commercially used vehicles in daily practice. The performance of D.I. Dieselengine largely depends on the combustion dynamics inside the cylinder. Hence, such combustion is influenced by thespray characteristics, fuel content and then the motion of the piston. The main problem with diesel engines is emissionsof nitrogen oxides (NOx) and particulates. In order to minimize the emissions, it is necessary to design the dieselengine with better in-cylinder flow (air-fuel mixing) and combustion process. Computational Fluid Dynamics (CFD)simulation helps to understand the Diesel engine temperature distribution and NOx species concentrations with respectto time. A small direct injection (DI) engine was chosen for the study. CFD simulation results were compared with thatof engine emission tests. This paper also presents the simulation results of direct injection diesel engine in-cylinderflow (air fuel mixing) and combustion.
