In order to study the influences of plateau environment on the performance of OPOC twostroke diesel engine, the combustion processes of OPOC engine at different altitudes were investigated with 3D simulation method. The influences of plateau environment on the airfuel mixing process inside the cylinder of OPOC two-stroke diesel engine were quantitatively analyzed according to the mixture characteristic parameters. Through the analysis of combustion characteristic parameters, the influences of plateau environment on the combustion process and performance of OPOC two-stroke diesel engine were studied. The results show that the mean in-cylinder pressure decreases, the mean in-cylinder temperature increases, the combustion process deteriorates, the fuel consumption and soot emission increase and the NOx emission shows an unobvious decrease in plateau environment.
