摘要： During a fuel cut, a recommended reactivated cylinder and a reactivatable cylinder are determined based on the stopped positions of an intake valve and an exhaust valve (step 104). A fastest reactivatable cylinder is then determined based on the crank angle, from among the recommended reactivated cylinder and the reactivatable cylinder (step 108). Also, the rotating direction of a motor when a variable valve drive apparatus starts to be driven again when the fastest reactivatable cylinder is made the reactivated cylinder is also determined. When a reactivation command is output, operation resumes from the fastest reactivatable cylinder when the situation calls for rapid reactivation (step 124). When the situation does not call for rapid reactivation, operation resumes from the recommended reactivated cylinder (step 118).

摘要： A first arm member and a second arm member are provided. The first arm member is positioned between a cam and a valve body to oscillate in synchronism with the rotation of the cam. The second arm member changes the angle of the first arm member in accordance with the rotation angle of a control shaft. The temperature prevailing in the neighborhood of the control shaft and cam is detected. The rotation angle of the control shaft is corrected so as to avoid the influence of the detected temperature.

摘要： The rotary motion of a camshaft is transmitted from a first drive cam to a slide surface of a swing cam arm via intermediate members so that the swing cam arm lifts a valve. In this instance, the operating characteristic of the valve changes when the rotation position of a control shaft changes to change the positions of the intermediate members on the slide surface. When the operating characteristic control mode for the valve is to be changed from variable control to fixed control, coupling means couples the swing cam arm and input arm, thereby causing a second drive cam to swing the swing cam arm. The setting for the lift amount of the valve that is obtained when the second drive cam swings the swing cam arm is not smaller than a maximum lift amount setting for a situation where the first drive cam swings the swing cam arm.

摘要： A valve train for an internal combustion engine (48) according to the present invention is a valve train (48) for an internal combustion engine (10) that uses motors (54A, 54B) to open/close intake valves (36) of cylinders. The motors (54A, 54B) drive the intake valves (36) for each of a plurality of groups of cylinders that perform an explosion stroke at substantially equal crank angle intervals. Since the intake valves (36) are driven for each of the plurality of groups of cylinders that perform an explosion stroke at substantially equal crank angle intervals, the explosion stroke is performed regularly even when an operation is conducted with only a particular group of cylinders. This makes it possible to inhibit driveability deterioration.
