摘要
Abstract
Diesel soot, NOx and noise emissions have restricted the diesel engine application, through commercial CFD software FIRE designed a combustion chamber model, emphatically of high-pressure co rail diesel engine mixture formation and combustion process were studied,shrink mouth low emissions combustion chamber structure advantages,the mixed gas from the parameters of the spray and combustion chamber matching problem on the optimization control of the direct injection,injection pressure and matching injector in the cylinder of the two-phase flow and combustion characteristic, using high-pressure co rail diesel machine was analyzed, thus to ensure the diesel engine's power and economy based on,reduce soot and NOx and noise emissions.关键词
