| Abstract: | Miller cycle is an effective way for deducing NOx emissions of diesel engine.A miller cycle thermodynamic model for turbocharged diesel engines was established in this paper.The effects of geometric and effective compression ratio,air fuel ratio,boost pressure and turbocharger efficiency on engine performance were analyzed.Considering the limits of maximum cylinder pressure and NOx emission,engine performances were optimized.The results showed that miller cycle thermal efficiency only can be improved under ... |
