Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2012/098671
Kind Code:
A1
Abstract:
An ECU (70A) is applied to an in-cylinder fuel injection internal combustion engine (50) equipped with a fuel injection valve (56) that injects fuel into a combustion chamber (E), an intake valve (54) and an exhaust valve (55) provided for the combustion chamber (E), and VVTs (57, 58) capable of causing valve overlap between the intake valve (54) and the exhaust valve (55). The ECU (70A) is equipped with an injection pressure setting unit that sets a lower injection pressure for the fuel injected by the fuel injection valve (56) when the VVTs (57, 58) cause valve overlap between the intake valve (54) and the exhaust valve (55) and the combustion chamber (E) is scavenged than when valve overlap between the intake valve (54) and the exhaust valve (55) is not caused.
