Title:
CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2018003652
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine which can improve the control accuracy of injection amounts of both partial lift injection and full lift injection.SOLUTION: A control device 40 of an internal combustion engine is employed to the internal combustion engine having a fuel injection valve 19 and a fuel supply system 30, and performs partial lift injection in which a valve body of the fuel injection valve 19 is not opened up to a full-open position, and full lift injection in which the valve body is opened up to the full open position. The control device 40 of the internal combustion engine comprises an electricity-carrying time setting part 41, a fuel pressure calculation part 42 and a smoothening processing part 43. The electricity-carrying time setting part 41 sets an electricity-carrying time in the full lift injection on the basis of smoothening fuel pressure which is calculated by the smoothening processing part 43, and sets an electricity-carrying time in the partial lift injection on the basis of fuel pressure which is calculated by the fuel pressure calculation part 42.SELECTED DRAWING: Figure 1
