| Abstract: | The single zone model in combination with detailed mechanism of chemical kinetics was used for simulation to predict the cylinder pressure,NOx emission and concentration of several radicals.Experimental and simulation results were compared.The results showed that the simulation could accurately predict the start of combustion and reasonably estimate the peak cylinder pressure and concentration of NOx emission.The model is applicable to optimizing engine parameters and achieving controlled combustion. |
