    Abstract: 在发出发动机停止指令(在S100为“是”)之后且规定值(CA#)被设定为目标相位(S110)的气门正时控制中,ECU在进气门相位(IV(q))尚未达到目标值(CA#)(在S120为“否”)的情况下在规定时间段内延迟允许发动机停止处(S130),使得在怠速状态下继续发动机运转的同时继续气门正时控制工作(S150)。然而,在从发动机停止指令发出起经过规定时间段之后(在S140为“是”),不管进气门相位是否已经达到目标值(CA#),ECU都允许发动机停止处理(S130)。结果,能增大在发动机停止运转中能由气门正时控制改变的气门正时量,且不会给驾驶员带来不舒适的感觉。

    Abstract: 一种阀定时调节装置(1),具有将第1旋转体(2)与第2旋转体(7)的相对转动约束在第2旋转体(7)的最大提前角位置、且由流体控制压力进行动作、解除所述约束的锁定销(14),还设有旋转体启动延迟装置,在第2旋转体(7)从最大提前角位置向延迟角方向开始转动时,由流体控制压力将锁定销(14)向两旋转体(2、7)的约束解除方向动作,然后将第2旋转体(7)朝延迟角方向启动,旋转体启动延迟装置将对第1旋转体与第2旋转体的滑接部进行密封的密封片的摩擦阻力设定成比作用于锁定销的旋转体约束解除方向的流体控制压力更大。采用本发明,在无工作油供给的状态下的内燃机停止时或启动时,对第1旋转体与第2旋转体的相对转动进行约束的锁定销不会因凸轮反作用力而咬合,在第1旋转体与第2旋转体开始相对转动之前,可解除锁定销对上述两旋转体的约束,能始终进行稳定控制,且可靠性高。

    Abstract: A timing pin module for an engine is disclosed herein. The timing pin module includes a mount end, an engagement end, an adapter, a pin, and a resilient member. The adapter, with a through hole is disposed on the mount end and is mountable to the housing cover. The pin has a longitudinal axis, a first end disposed on the engagement end, and a second end disposed on the mount end. The pin is slideably disposed in the through hole of the adapter and moves between an extended position and a retracted position. The resilient member has a first end engaged with the pin and a second end engaged with the adapter. Further, the first end of the pin engageably retains the flywheel in the top dead center position while extended, and makes sliding contact with a portion of the flywheel that is in the retracted position.

    Abstract: A camshaft phaser attachment system is provided for attaching a camshaft phaser to a camshaft of an internal combustion engine. The camshaft phaser attachment system includes a camshaft phaser for controllably varying the phase relationship between a crankshaft and the camshaft. The camshaft phaser attachment system also includes a camshaft phaser installation tool having a handle with a head sized to be inserted through an opening of a cover of the camshaft phaser. A plurality of notches formed on a rotor of the camshaft phaser interfit with a plurality of tangs of the head. The head includes a recess on the periphery to provide clearance relative to a bias spring capture flange extending radially inward from the opening. The head also includes a central passage extending through the head to allow a tightening tool to tighten a bolt used to hold the camshaft phaser to the camshaft.
