Abstract
Electrical control unit(ECU) is the intelligent kernel of the electronic fuel injection system.Its main function is to take control of ignition advanced angel and spray pulse signal on the basis of the throttle openness and rotational speed of engine and in combination with other parameters,thus optimizing the engine combustion process.This paper,taking MAP working state as a example,introduces the development of ECU system based on PIC microprocessor and its principle and hardware.
