At the same time, the fulcrum side of the rocker arm of the intake valve and the operating end side of the plunger are connected, and inside the hydraulic cylinder mechanism, pressurized oil penetrates into the oil chamber under the plunger in the high speed range of the engine. A variable intake valve mechanism that incorporates a controller that closes the exhaust port of the engine to lock the plunger, and opens the exhaust port in the low rotation range to set the plunger in a free state.
