This model is developed based on the concept of Hiroyasu's multizone combustion model. It takes nozzle injection (spray) parameters, induction swirl, air and fuel composition into consideration. The models of zone velocity, air entrainment rate, fuel droplet evaporation rate, mixture combustion rate are upgraded according to the latest papers. Various parameters, such as cylinder pressure, heat release rate, NOx and soot emissions, etc. are simulated. The simulated zone velocity and spray tip penetration are compared with those computed by Hiroyasu. The simulation results show good agreement with the experimental data.
