Title:
CONTROL DEVICE FOR ENGINE
Document Type and Number:
Japanese Patent JP3441471
Kind Code:
B2
Abstract:
PURPOSE: To prevent any deviation of a fuel injection amount owing to lowering of an intake air negative pressure when an on-off valve is opened and to prevent the dry deviation of a fuel injection amount owing to the operation delay of the on-off valve, in an engine provided with a D-jet port system electronic control fuel device and an on-off valve to open and close an intake air delay close port for reducing any pumping loss.
CONSTITUTION: A control device for an engine comprises an on-off valve target opening computing circuit 34, a first correcting circuit 37 to correct a fuel injection amount based on the target opening of an on-off valve, a means to detect the actual opening of the on-off valve, a circuit 38 to compare the target opening of the on-off valve with the actual opening; and a second correcting circuit 39 to further correct a fuel injection amount based on comparison by the comparing circuit 38.
