Effects of fuel injection discharge curve and injection pressure on upgrading power and combustion parameters in heavy-duty (HD) diesel engine with computational fluid dynamics (CFD) simulation

In this study, the effects of fuel injection discharge curve and injection pressure onpower upgrade of heavy-duty diesel engine by simulation of combustion process in AVL-Fire software are discussed simultaneously. Hence, the fuel injection discharge curve is changed from semi-triangular to rectangular which is usual in common rail fuel injection system. Injection pressure with respect to amount of injected fuel and...
