Title:
INTERNAL COMBUSTION ENGINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/152065
Kind Code:
A1
Abstract:
In the present invention, air-intake reduction suppression control, which is for suppressing a reduction in the amount of air taken in by an engine, is executed if a tracking delay occurs for an actual fuel pressure with respect to a target fuel pressure when an engine decelerates. As a result of increasing the air intake amount using this air-intake reduction suppression control (reducing the amount by which air-intake is reduced), a required injection amount is increased and an injection time is consequently made longer so that the injection time will not fall below a prescribed value (a minimum injection time or a value slightly larger than such time). Further, ignition retarding control for retarding the ignition timing of the engine is carried out, and carried out is power generation increase control for increasing the amount of power generated by an alternator driven by the motive power of the engine. Due to this configuration, the increased amount of engine torque due to the air-intake reduction suppression control is absorbed by the decreased amount of engine torque due to the ignition retarding control and the increased amount of load torque due to the power generation increase control.
