Title:
INTERNAL COMBUSTION ENGINE CONTROL APPARATUS
Document Type and Number:
Japanese Patent JP2023108256
Kind Code:
A
Abstract:
To provide an internal combustion engine control apparatus with a deterioration of exhaust emission suppressed while securing the startability of an internal combustion engine.SOLUTION: An internal combustion engine control apparatus includes: an intermittent operation control part for executing automatic stop and automatic start of an internal combustion engine that has a port injection valve and an in-cylinder injection valve; a determination part for determining whether rich control is performed in which an air-fuel ratio is controlled to a rich side than a theoretical air-fuel ratio in automatic start, and whether an integral air-intake amount of the internal combustion engine since starting the automatic start is smaller than a given threshold; and an injection control part for executing, in a case where the determination by the determination part is positive, at least one of causing injection timing of the in-cylinder injection valve to approach timing of an intake stroke bottom dead point and decreasing a ratio of injection amount from the in-cylinder injection valve to a total fuel injection amount from the port injection valve and in-cylinder injection valve, compared to a case where the determination by the determination part is negative, thus executing suppressed injection control to suppress an exhaust amount of exhaust particulate from the internal combustion engine.SELECTED DRAWING: Figure 3
