Abstract: PROBLEM TO BE SOLVED: To suppress execution of rotation reduction preventing control along with reduction of a target rotation speed during a travel stopping process of a vehicle, and to avoid difficulty for quickly performing travel stop of the vehicle caused by sudden rise of an engine rotation speed due to the rotation reduction preventing control. SOLUTION: When an engine 1 shifts to idling operation in the travel stopping process of an automobile, the target rotation speed of idling rotation speed control is reduced only under a condition that a road surface has low friction coefficient, and a determination speed of the rotation reduction preventing control is also reduced along with the reduction of the target rotation speed. When an engine rotation speed is reduced along with the reduction of the target rotation speed thereby, the engine rotation speed is reduced by action of disturbance in an rotation stop direction to a driving wheel 6 (such as frictional force from a road surface side). The engine rotation speed is restrained from being equal to or lower than the determination rotation speed. Accordingly, when the target rotation speed is reduced during the travel stopping process of the automobile, the execution of the rotation reduction preventing control is restrained in association therewith.

Abstract: PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of reducing compression work of cranking, while securing combustion stability, when starting the internal combustion engine, by properly setting an intake valve opening characteristic on the basis of a piston stopping position, after stopping the internal combustion engine.
SOLUTION: The intake valve opening characteristic is set to intake valve delay opening on one cylinder group where the piston stopping position acquired after stopping the internal combustion engine is before intake TDC (Step 104). Among the other cylinder group, a cylinder where the piston stopping position is nearest to compression TDC before the compression TDC is specified (Step 106). When the piston stopping position of a specific cylinder is not included in a valve opening period in intake valve delay closing, the specific cylinder is set to the intake valve delay opening, and the other cylinder group except for the specific cylinder is set to the intake valve delay closing (Step 112).

Abstract: PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of separating a diluted fuel from an oil while ensuring the excellent emission characteristic when oil dilution occurs.
SOLUTION: When it is determined that oil dilution occurs, the rise of oil is generated by the in-cylinder negative pressure generated by delaying and/or advancing an intake valve, and a fuel is evaporated from the oil diluted with the fuel (Step 106). In this step 106, discharge of the evaporated fuel to an exhaust passage is prevented by stopping an exhaust valve in a closed state.

Abstract: PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine, which can suppress variation in an intake air amount between cylinders while sufficiently exerting the effect of improving fuel economy.
SOLUTION: When detected variation in lift amount and detected variation in working angle between cylinders are larger than a reference value, a mean value of valve closing timing of an intake valve on the most advanced side and valve closing timing of the intake valve on the most delayed side is calculated (a step 112). Target valve closing timing of the intake valve is set so that the calculated mean value becomes the bottom dead center (a step 114). Since the variation in position of a piston in closing the intake valve becomes minimum, the variation in intake air amount between cylinders is sufficiently suppressed. Valve closing timing of an exhaust valve is set to be the same as valve opening timing of the intake valve or to be on the more delayed side than the valve opening timing of the intake valve (a step 116).
