| Abstract: | The discrete particle ignition kernel(DPIK) model and one step combustion model are integrated into KIVA-3V code,and a multidimensional model for studying gasoline engine MAP is built.A simulation on the combustion process of gasoline engine is performed and an optimization on ignition advance and injection pulse-width is conducted with performance,fuel economy and indicated work as objectives and some parameters in the model are determined based on test data.The MAP obtained from the simulation can be taken as the original MAP of EFI gasoline engine. |
| Keywords: | Gasoline engine Electronic fuel injection MAP Multidimensional model Numerical simulation |
