【Abstract】 Control system software and hardware design of a MPI LNG engine is carried out. The ECU is composed of 32 bit high performance CPU MC68332. An engine manage system (EMS) software is setup with the real time multitask technology, and programmed with the combination of C and assemble language. Details of the system hardware as well as the structure of the EMS are both described.更多还原
