| Abstract(E) | Our turbulent combustion model had provided turbulence distributions in a cylinder using random digits, and it was able to simulate combustion cycle-by-cycle variations in gasoline engines. However, fluctuations of the EGR ratio and the internal EGR distribution were not able to be calculated. So a multi-zone combustion model has been developed to deal with them. This calculation model makes us know how the fuel distribution in a cylinder effects the cycle-by-cycle variations. From this calculation results, it can be understood that the fluctuations of the EGR ratio and the internal EGR distribution do not have significant effect on the cycle-by-cycle variations. Some calculation results and the details of the multi-zone combustion model are shown here. |
