摘要： PROBLEM TO BE SOLVED: To provide an operation control device for a variable intake valve suppressing abnormal noise generated from a vacuum tank communicating with an intake system.
SOLUTION: The operation control device for the variable intake valve of the engine is provided with a plurality of variable intake valves keeping communication/non-communication between a first intake air passage continuously provided to a first cylinder group of an engine and a second intake air passage continuously provided to a second cylinder group, and a vacuum tank communicating with the first intake passage or the second intake air passage and keeping vacuum in the intake air passage via a one-way valve, and controls opening and closing of the plurality of variable intake valves by using vacuum in the vacuum tank. The device is provided with a valve control means (steps S11 to S17) making closing timing or opening timing of the plurality of variable intake valves different when the plurality of variable intake valves are simultaneously switched from an opened condition to a closed condition, or from the closed condition to the opened condition matching increase of engine speed.
