摘要： A system and method for controlling a variable valve actuation system for an engine is provided. An engine valve is moved between a first position where the engine valve blocks a flow of fluid and a second position where the engine valve allows a flow of fluid. Fluid is provided to a chamber of a valve actuator adapted to operatively engage the engine valve. A parameter indicative of a viscosity of the fluid provided to the chamber of the valve actuator is sensed. Fluid is trapped within the chamber of the valve actuator to prevent the engine valve from moving to the first position. A response time of the valve actuator is determined based on the viscosity of the fluid provided to the chamber of the valve actuator. The response time indicates the time required to release the fluid from the chamber of the valve actuator to allow the engine valve to move to the first position.

摘要： A first camshaft (24) operates the exhaust valves (18) and a first intake valve (12) for each cylinder (8), and a second camshaft (38) operates the second intake valve per cylinder (14), the second camshaft further having a phase adjuster (62) for adjusting the timing of the second camshaft (38) relative to the first camshaft (24). Both the exhaust valves and the first intake valve arc actuated by rocker arms (30),(36), for providing a short and light-weight first intake valve rocker (36) having a high maximum operational speed capability and low friction.

摘要： A cam phaser is mounted on the intake camshaft of a diesel engine and is operable to selectively retard timing of only the intake valves relative to the crankshaft. The purpose of retarding timing of the intake valves is to retard valve closing sufficiently to shorten the effective compression strokes of the pistons and thus reduce the effective compression ratio. This occurs when the intake valves remain open past piston bottom dead center for a desired period into the normal compression stroke phase of engine operation. This reduces compression pressures so that combustion temperatures are reduced and exhaust emissions, primarily NOx, may be thus limited under conditions of warmed-up engine operation.

摘要： A fast-acting rotor-locking mechanism for a vane-type camshaft phaser. A straight-sided locking pin is disposed in a bushing in the rotor and is urged into a sprocket well by a return spring. A pad disposed at the bottom of the well is a travel stop for the pin. When the pin is fully seated against the pad, the pad covers a portion of the end of the pin. The uncovered portion of the pin end, exposed to oil pressure for unlocking the pin when it is fully seated, is decreased over the prior art pin, permitting use of a lighter locking spring having a lower spring rate. Because of the lighter locking spring, the pin accelerates more rapidly and unlocks significantly faster than in a comparable prior art phaser.
