Abstract

In automotive industry the new combustion processes focused on clean diesel combustion, decrease emissions such as particulate matter, NOx emission, unburned hydrocarbons (HC) and carbon monoxide (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 (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.
