Abstract: A method of assembling a variable valve timing apparatus includes steps of temporarily fixing a driven-side rotation body to a base member in a first rotation restricting state by a process of engaging a first projecting and retracting member with the base member of a driving-side rotation body and the driven-side rotation body followed by a process of rotating either the base member or the driven-side rotation body, providing a supplementary member of the driving-side rotation body to the driven-side rotation body to establish a second rotation restricting state by a process of installing the supplementary member to the base member in a state where the second projecting and retracting member engages with the supplementary member and the driven-side rotation body followed by a process of rotating either the supplementary member or the driven-side rotation body, and fastening the supplementary member and the base member by using a fastening member.

Abstract: In valve timing control after issuance of an engine stop instruction with a prescribed value set as a target phase, an ECU delays permission of an engine stop process within a prescribed time period while an intake valve phase has not yet reached the target value, so that a valve timing control operation is continued while the engine operation is continued in an idle state. After the lapse of a prescribed time period from the issuance of the engine stop instruction, however, the ECU permits the engine stop process no matter whether the intake valve phase has reached the target value or not. As a result, the amount of valve timing that can be changed by the valve timing control in the engine stop operation can be increased, without causing any uncomfortable feeling of the driver.

Abstract translation: 在以规定值设定为目标相位的发动机停止指示发出后的气门正时控制中，在进气门相尚未达到目标值的情况下，ECU在规定时间内延迟发动机停止处理的许可， 在空转状态下继续发动机运转时继续进行气门正时控制动作。 然而，在从发动机停止指令发出规定的时间段之后，ECU不管进气阀相位是否达到目标值，都允许发动机停止。 结果，可以增加可以通过发动机停止操作中的气门正时控制而改变的气门正时的量，而不会引起驾驶员的任何不适感。

Abstract: A camshaft phaser including a locking clearance setting pin is provided. The camshaft phaser includes a stator including a first plurality of pin holes extending axially in at least one of the radially inwardly extending lobes arranged along an arcuate path. A locking cover engages against a first axial end face of the stator and includes a locking pin bore and a second plurality of pin holes arranged along the arcuate path and angularly spaced apart from one another by a different angular spacing than the first plurality of pin holes. A pin extends through a respective one of the first plurality of pin holes and a corresponding one of the second plurality of pin holes, such that a location of the pin sets an angular adjustment of the locking pin bore relative to the stator.

Abstract: A gear meshing system is disclosed. The gear meshing system includes a pair of gears engaged with each other through a first plurality and a second plurality of teeth thereon. Each gear has a mark which is oriented in a predetermined relationship with a timing slot on the gear. Each gear of the pair of gears is identical to the other. Accordingly, by utilizing a marking scheme in accordance with the present invention the same gear part can be used with multiple shafts and thereby assure accurate meshing/timing upon assembly. Accordingly, the need for additional part numbers will be minimized and excessive part proliferation will be avoided.
