Prediction of Mixture Formation and Heat Release in Diesel Engines 780225
A multi-zone model is developed to predict the rate of heat release in direct injection diesel engines. By considering the complete air-fuel jet mixing process and temperature dependent reaction rates in each zone, the model also enables subsequent spacial and temporal history of burning rate, local temperature and air-fuel ratio etc. to be calculated.
It is shown that the model is capable of predicting realistic rate of pressure rise and heat release rates and responds sensibly to changes in injection timing, swirl ratio and air temperature.
