| Abstract: | Electronic Fuel Injection(EFI) and Electronic Ignition(EI) system were designed based on Freescale MPC564 microprocessor to meet requirements for energy saving,emission reduction and anti-interference feature of four-cylinder gasoline engine.Control strategies based on the platform were realized,and flow diagram for injection and ignition was designed also.Direct driving for fuel injector and ignition coil with MC33810 chip was achieved in this paper.It was showed by experiments that the system had some characteristics,such as simple circuit,flexible driving mode,strong stability and long service life. |
