AB - The traditional mechanical fuel supply system has already been no way to  satisfy the requirement of more stringent fuel consumption and emission  legislation. For the past few years, it has been the hot topic to improve  combustion and emission performance of diesel engine through optimizing the  fuel injection strategy. All kinds of spray, combustion and emission models  were studied and then a new 3D spray model coupled with the cavitating flow  inside the nozzle was put forward to well consider the primary atomization  induced by cavitating flow and turbulence in nozzle holes. The model,  combined with combustion and emission models were used for simulating the  single-injection combustion of 1015 diesel engine and validated through  comparing the results from simulation with those from experiment. With the  above verified models, different injection strategies were further  investigated to reveal the effect of pilot injection (PI) timing, quantity  and main injection (MI) timing on combustion noise and exhaust emission of  diesel engine.
