PERFORMANCE ANALYSIS OF A DIESEL ENGINE WITHIN A MULTI- DIMENSIONAL FRAMEWORK
PERFORMANCE ANALYSIS OF A DIESEL ENGINE WITHIN A MULTI- DIMENSIONAL FRAMEWORK
In this study, large-bore diesel engine combustion was modeled using development combustion modelExtended Coherent Flame Models 3 Zones (ECFM-3Z). During this work, the study was made about an engineconfiguration 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 animportance in designing efficient engines. Effects of in-cylinder flow structures, fuel injection and designparameters were investigated for the engine performance and emission results. The results agree broadly withexperimental and computational studies. As a result, it is aimed to find out the flow structure, spray, combustionand emission characteristics of the large-bore diesel engine. In a precombustion chamber structure, it is seen thatcontrolled combustion starts and then high-pressure gas mixture uniformly spreads into the main combustionchamber.
