    Abstract: Monitor system of explosion pressure for internal combustion engine(ICE) is developed based on the MCS-51 microcontroller.The system realizes acquisition of explosion pressure,calculation for explosion pressure and pressure rise rate,display on the LED and communication with the host computer.With timer interrupt mode,the system may achieve acquisition of explosion pressure with no crank angle signal.Test results prove that the system meets the monitor requirements while I.C.E in different conditions and gets good results.
