Abstract: Apparatus and method for controlling valve movements in an internal combustion engine that has at least one inlet valve (12) and at least one exhaust valve for controlling the connection between the combustion chamber in the cylinder and an inlet system and an exhaust system respectively. A rotatable camshaft is provided that has a cam curve including a rising ramp (10a) and a falling ramp (10b) that is designed to interact with a valve mechanism (14) for actuation of the inlet or exhaust valve (12) under the action of a valve spring (13). The valve mechanism (14) includes control members (21, 22, 23, 24, 25 and 26) that allow return movement of the valve mechanism to be controlled during the closing phase of the inlet valve (12) or the exhaust valve, independently of the falling ramp (10b) of the cam curve. The control members (21, 22, 23, 24, 25 and 26) are arranged so that the closing of the valve can be delayed for an adjustable period of time by means of a hydraulically adjustable force counteracting the closing force of the valve spring.

Abstract: A fault detection system for detecting a fault in a lifter oil manifold assembly (LOMA) of a displacement on demand engine that is operable during transition from activated and deactivated modes includes a first fluid circuit of the LOMA that selectively provides pressurized fluid to regulate operation of the engine between activated and deactivated modes. The fault detection system further includes a sensor that is responsive to fluid pressure of the LOMA and that generates a pressure signal based thereon. A control module outputs a control signal to switch operation of the engine between the activated and deactivated modes. The control module further determines a pressure differential based on a first pressure prior to switching between the modes and a second pressure after switching between the modes.

Abstract: A rocker arm is adapted for use with an engine including a push rod, a valve unit and a pivot ball disposed on a supporting frame. The rocker arm is connected pivotally to the supporting frame, and includes a main plate having a central opening defined by an upper edge, a horizontal lower edge disposed under the upper edge, and two curved lateral edges interconnecting the upper and lower edges. The lower edge has an intermediate portion formed with an outwardly flared recess that defines an upwardly facing socket engaging the pivot ball. A first arm plate is connected integrally to a lateral side of the main plate and is driven by the push rod. A second arm plate is connected integrally to an opposite lateral side of the main plate and operates the valve unit.
