CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINES

Title:

CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINES

Document Type and Number:

WIPO Patent Application WO/2016/088190

Kind Code:

A1

Abstract:

A control device for internal combustion engines, having: a first fuel injection valve that injects fuel directly into a combustion chamber; and a pressure regulator capable of changing the fuel pressure supplied to the first fuel injection valve. When prescribed fuel cut conditions are met, a fuel cut is implemented whereby fuel injection by the first fuel injection valve is stopped. When prescribed fuel cut recovery conditions are met during fuel cut, fuel injection by the first fuel injection valve is recommenced. When fuel injection is recommenced after fuel cut, the fuel pressure supplied to the first fuel injection valve is set higher than the normal fuel pressure determined in accordance with the driving state. As a result, spray atomization and vaporization are promoted and the exhaust particle discharge amount and the number of discharged exhaust particles can be suppressed, when recommencing fuel injection after fuel cut has ended.
