cfd simulation of a wall film during fuel injection and combustion three cylinder turbocharged gasoline direct injection engine

In this research, a 3d-cfd model was created to investigate the behavior of spray and combustion in a three-cylinder gdi engine using six-hole nozzles’ injector. to validate the model, in-cylinder data pressure was conducted at iran khodro power train company (ipco) under wide-open throttle and 5500 rpm conditions. the obtained data were incorporated into the cfd model to simulate the spray evolution and combustion process inside the cylinder during fuel injection. drplet temperature and lambda distribution during 30 deg to 279 deg afte injection were displayed. temperatute distribution during 2 to 40 deg atdc temperatute distribution during 2 to 40 deg atdc were illustrated in the paper. finally, evaporated fuel and wall film of cylinder head, liner, piston. intake and exhaust valves were and equivalence ratio in combustion chamber have been studiewere illustrated in the paper. finally, evaporated fuel and wall film of cylinder head, liner, piston. intake and exhaust valves were and equivalence ratio in combustion chamber have been studied.
