筒エンジン。[Claims for Utility Model Registration] A shaft equipped with a medium for opening and closing the passage is rotatably disposed in each of the intake passages and exhaust passages of a plurality of cylinders to be deactivated, and the intake and exhaust passages of each deactivated cylinder are connected to the medium. intake passage and exhaust passage when closed by. A first cam for opening and closing a valve that opens and closes at least the passage portion on the communication side and the combustion chamber is configured such that a passage portion of at least one of the passages connected to the combustion chamber side can communicate with each of the idle cylinders, and A second cam having a diameter larger than the cam nose diameter and for stopping the operation of the valve in an open state is rotatably incorporated into the first cam, and 1. A means for rotationally driving the second cam separately from the first cam is provided, and the opening and closing of the intake and exhaust passages by the medium is controlled by the rotational movement of the second cam through an interlocking means for the operation of the second cam driving means. A variable cylinder engine characterized in that the variable cylinder engine is interlocked with the operation stoppage and release of the stoppage when the corresponding valve is in the open state.
