Title:
インジェクタ駆動制御装置
Document Type and Number:
Japanese Patent JP4110751
Kind Code:
B2
Abstract:
The invention relates to an injector driving control apparatus (0) that operates with minimum power consumption while ensuring linearity (proportionality between the current supply duration and fuel injection volume of the injector) in a wide fuel pressure range. Providing a coil current feedback circuit and controlling the current feedback duration according to fuel pressure after applying the current at a boost voltage. The present invention enables optimal control of the injector (8) and hence, the improvement of its fuel injection volume characteristics (linearity) and the reduction of the heat generated in the injector driving control circuits (7).
