Abstract

When the rotation speed of an in-cylinder injection engine 1 reduces to a rotation speed for increasing the amount of air which has been set on a higher rotation speed side than a fuel supply-return rotation speed, the amount of air is increased. Thereafter, when the rotation speed of the in-cylinder injection engine 1 reduces to the fuel supply-return rotation speed, the supply of fuel is resumed in the fuel cut mode to securely prevent the rotation speed from lowering and to reduce a torque down during resumption of fuel-supply and deteriorated fuel consumption.
