Design of Automobile Electron Ignition System Based on single chip

A kind of electronic ignition system based on single chip is designed in this paper.The control unit of the system is AT89C2051 single chip.By the crank position sensor,the temperature sensor,the knocking meter,the damper opening sensor and the corresponding circuit,the state data of the running motor is obtained.After processing the data,single chip calculates the ignition angle of advance and gives the firing signal.The firing signal controls the firing circuit to fire the mixture of air and oil.The design of system hardware and system software is accomplished.The system has been debugged successfully.
