In this study, large-bore diesel engine combustion was
modeled using development combustion model Extended Coherent Flame Models 3
Zones (ECFM-3Z). During this work, the study was made about an engine
configuration with compression, spray injection, combustion and emission of the
diesel engine. Prediction of in-cylinder combustion phenomenon, effects of turbulence
levels, flow structures and emission modeling have an importance in designing
efficient engines. Effects of in-cylinder flow structures, fuel injection and
design parameters were investigated for the engine performance and emission
results. The results agree broadly with experimental and computational studies.
As a result, it is aimed to find out the flow structure, spray, combustion and
emission characteristics of the large-bore diesel engine. In a precombustion
chamber structure, it is seen that controlled combustion starts and then
high-pressure gas mixture uniformly spreads into the main combustion chamber.
