Abstract: A valve train for an internal combustion engine that uses motors to open/close intake valves of cylinders. The motors drive the intake valves for each of a plurality of groups of cylinders that perform an explosion stroke at substantially equal crank angle intervals. Since the intake valves 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.

Abstract: Engine starting apparatus comprising a one way clutch. A first oil seal is located on the outer side of a second oil seal in the radial direction of a ring gear. Upon starting of an engine, the time that the first oil seal is slid on the ring gear is short, and after the start of the engine, the first oil seal is not slid on the ring gear. The second oil seal is located on the inner side of the first oil seal in the radial direction of the ring gear. Therefore, the second oil seal hardly deteriorates even if slid on a flywheel at high speed after the start of the engine. By locating the first and second oil seals at different positions in the radial direction of the ring gear, it is possible to improve the startability and the lifetime of a starting apparatus. At least one oil seal has a taper shape in order to generate a thrust force which forces the ring gear away from the flywheel.

Abstract translation: 发动机起动装置，包括单向离合器。 第一油封位于第二油封的外侧沿齿圈的径向方向。 在发动机起动时，第一油封在齿圈上滑动的时间短，在发动机起动之后，第一油封不会在齿圈上滑动。 第二油封沿着齿圈的径向位于第一油封的内侧。 因此，即使在发动机起动之后高速地在飞轮上滑动，第二油封也几乎不劣化。 通过将第一和第二油封定位在环形齿轮的径向上的不同位置，可以提高起动装置的起动性和使用寿命。 至少一个油封具有锥形形状，以产生迫使齿圈远离飞轮的推力。

Abstract: An internal combustion engine including a variable valve mechanism that can avoid an unnecessary friction increase while preventing a hydraulic lash adjuster from pumping up. When a first engine speed is a critical rotation speed at which the inertia force of the variable valve mechanism exceeds the maximum load on a lost motion spring and a second engine speed is a critical rotation speed at which the inertia force of a valve and rocker arm exceeds the maximum load on a valve spring, the maximum loads are set such that the first engine speed is lower than the second engine speed.
