Control system for controlling fuel injection into diesel engine of vehicle, has drive circuit for driving actuator based on fuel injection instruction information, where information is transmitted from control unit to injector

摘要

The system (10) has a drive circuit for driving a piezoelectric-type actuator (25) based on fuel injection instruction information, which is corrected on the basis of a correction value. An injection instruction valuation section is provided in an engine control unit (ECU) (11). An injection characteristic detection section, a correction value calculation section, an injection instruction value correction section and the drive circuit are provided in a fuel injector. The injection instruction information is transmitted from the ECU to the fuel injector.
