A control device of an internal-combustion engine
Document Type and Number:
Japanese Patent JP6187709
Kind Code:
B2
Abstract:
There are provided a first fuel injection valve arranged to directly inject a fuel into a combustion chamber. When a predetermined fuel cut condition is satisfied, a fuel cut by which a fuel injection by the first fuel injection valve is stopped is performed. When a predetermined fuel cut recovery condition is satisfied during the fuel cut, the fuel injection of the first fuel injection valve is restarted. At the restart of the fuel injection after the fuel cut, the pressure of the fuel supplied to the first fuel injection valve is increased to be greater than a normal state fuel pressure determined in accordance with a driving state. With this, it is possible to promote atomization and vaporization of spray at the restart of the fuel injection, and to suppress the discharge amount of the exhaust particulate and the discharge number of the exhaust particulate.
