Abstract :In automotive industry the new combustion processes focused on clean diesel combustion, decrease emissions such as particulate matter, NOx emission, unburned hydrocarbons insert ignore into journalissuearticles values(HC); and carbon monoxide insert ignore into journalissuearticles values(CO); emissions. At this point, prediction of in-cylinder combustion behavior, effects of turbulence levels, flow structures and emission modeling have an importance to design efficient engines. In this study, diesel engine combustion was modeled by a development combustion model Extended Coherent Flame Models 3 Zones insert ignore into journalissuearticles values(ECFM-3Z);. During this modeling, a calculation was made about an engine configuration with compression, spray injection, combustion and emission of the diesel engine with direct injection. Effects of in-cylinder flow structures, fuel injection and design parameters were investigated for the engine performance and emission results. The results agree qualitatively with experimental and also zero dimensional computational studies.
