| Abstract: | The fuel injection dynamic model can well describe how to accurately control the fuel supplied to the engine and can provide the main control parameters.The development and application of the compressed natural gas(CNG) multipoint injection(MPI) system based on the fuel injection dynamic model for the gasoline and CNG bi-fuel vehicle are discussed.The results indicate that the compressed natural gas multipoint injection system can meet the emission requirement and can effectively reduce the power loss and f... |
