Abstract:A predictive model of heat release rate was established by means of BP neural network. After testing, the prediction model was proven to have high precision and could be used as a new means for the heat release calculation of the dual fuel engine. At the same time, the effeets of speed and load on the heat release rate were also studied. The results show that with the decrease of the speed, both the ignition timing and the corresponding phase of the top heat release rate of biogas-diesel dual fuel engine come earlier. But when the speed is fixed and the load increases, the ignition timing advances, the ignition delay period shortens, the maxium heat release rate increases, and its corresponding crank advanees with a serious phenomenon of post-combustion.
