摘要： An engine unit includes a valve driving mechanism in which a cam having its cam profile axially varying continuously is slid along the axis of the cam shaft to control continuously a lift characteristic of an intake valve to be steplessly variable. In the control device of the engine, when the engine is, determined to be in a idling state by an idling-state determining unit, a target cam position is obtained according to a target valve lift amount calculated based on the cooling water temperature by a target cam position calculated unit, and the target cam position is corrected according to atmospheric pressure, an engine oil temperature, an ATF temperature, and an intake temperature, so that an engine rotation will be stabilized in the idling state.

摘要： A three-dimensional cam of a three-dimensional map state, having uncountable cam profiles continuously ranged along a rotation axis direction, and a valve lifter following a cam surface of the three-dimensional cam are included, and a lift characteristic of a valve is continuously controlled by relative motions of the three-dimensional cam and the valve lifter. The three-dimensional cam has cam top portions formed to have a smoothly ranged edge line substantially along the rotation axis direction thereof, and a part of the edge line includes at least one valley portion to take on a row of peaks. The cam peak portion of the cam top portion which forms the valley portion of the edge line is moderately set to be deviated toward a delayed side with reference to the rotation direction of the cam from the other cam peak portions.
