Title:
CONTROL DEVICE, CONTROL METHOD, AND PROGRAM FOR FUEL INJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/199577
Kind Code:
A1
Abstract:
It has not been possible to minimize combustion fluctuation when the injection amount of a fuel injection device varies from cylinder to cylinder. A control device 150, which controls a fuel injection device 101 that injects fuel multiple times in one combustion cycle, is provided with a control unit 500 that calculates the fuel injection amount at each injection performed in one combustion cycle, and performs control so that as the injection amounts of injections performed before the final injection become larger than the injection amount of the final injection in one combustion cycle to a greater extent, the injection pulse width of an injection pulse supplied to the fuel injection device 101 at the final injection is made less than the injection pulse widths of injection pulses supplied to the fuel injection device 101 at injections performed before the final injection to a commensurately greater extent.
