Title:
HIGH-PRESSURE INJECTOR CONTROLLER
Document Type and Number:
Japanese Patent JP2016113955
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a high-pressure injector controller capable of suppressing variation of an injection amount.SOLUTION: A high pressure injector controller 1 controlling drive of an injector includes a booster circuit, pressure rise time detection means 20, pressure rise capacity calculation means 21, and injection time correction means 22. The booster circuit accumulates energy in a capacitor on the basis of voltage supplied from a battery. The pressure rise time detection means 20 calculates pressure rise time ΔT required for changing of a capacitor voltage from a battery voltage to a target pressure rise voltage. The pressure rise capacity calculation means 21 calculates pressure rise capacity α of the booster circuit on the basis of the pressure rise time ΔT. The injection time correction means 22 corrects injection setting time of the injector on the basis of the pressure rise capacity α.SELECTED DRAWING: Figure 7
