Abstract
An Hybrid combustion process is analysed by a multi-zone predictive model created from a multi-zone direct injection model and an autoignition prediction model.
Multi-zone direct injection model can explain the direct Diesel injection combustion and is closely connected with the heat provided from the intake fuel injection autoignition model.
This model can forecast the pressure chamber and the heat release of hybrid combustion process varying the intake fuel characteristics, the amount of total fuel introduced, the homogeneous and heterogeneous charge relation and the main start injection time.
By forecasting hybrid combustion characteristics will allow us to see the pressure and heat release evolution under different conditions, and will let us predict the fuel consumption, the NOx generation and the combustion noise variations respect to the standard direct injection combustion process.
