Abstract: A guide rail (1, 22) for valve tappets (2) of an internal combustion engine is provided. The guide rail (1, 22) has receptacle spaces (4), which are each used for receiving one of the valve tappets (2) and in which there are flattened sections (6) interacting in a positive-fit connection with key surfaces (7) of the valve tappets (2), such that each of the valve tappets (2) is protected from rotating about its longitudinal axis, with the flattened sections (6) permitting alignment of the valve tappet (2) parallel to the flattened sections (6). Here, the guide rail (1, 22) is formed as a metal carrier (3, 25) and rotational protection elements (8, 9, 23), which are fixed on this carrier, have the flattened sections (6) which also permit alignment of the valve tappet (2) orthogonal to the flattened sections (6), in that each flattened section (6) belonging to one of the receptacle spaces (4) can be displaced relative to the metal carrier (3, 25).

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 valve control mechanism is provided for an overhead valve, internal combustion engine having a camshaft moving a pushrod to move a rocker arm that in turn moves the valve. Three aligned rollers are fastened to the end of the pushrod adjacent the rocker arm. The outer two rollers roll along parallel profiled surfaces that control at least the valve lift and ramp. The middle roller rolls along an engaging surface on the rocker to move the rocker arm in a motion determined by the configuration and location of the profiled surfaces and the engaging first and second rollers. The outer rollers rotate in a direction opposite the middle roller.

Abstract: A four stroke engine has a camshaft driven by a crankshaft. A decompression member is disposed on the camshaft. The decompression member is movable between a decompression position and a non-decompression position. A portion of the decompression member generally places the valve at an open position when the decompression member is placed at the decompression position and releases the valve from the open position when the decompression member is placed at the non-decompression position. A regulating member is disposed on the camshaft. The regulating member regulates the decompression member to prevent movement of decompression member from the decompression position when the regulating member is placed at a first position. The regulating member releases the decompression member from the decompression position when the regulating member is placed at a second position. A bias member is arranged to urge the regulating member toward the first position. The regulating member is movable toward the second position against the urging force of the bias member when a rotational speed of the camshaft exceeds a predefined speed.

Abstract: The invention provides a valve train for an internal combustion engine, comprising an elongate anti-rotation bridge (16) acting as a retention device and a mounting aid and comprising receptions (18) for valve lash adjusters arranged spaced behind one another. A valve adjuster configured as a roller tappet (17) is arranged in each reception (18) while being directed through a tappet roller (22) toward a cam of a camshaft. The roller tappet (17) is retained for longitudinal displacement in the reception (18) and is secured against rotation through flat key surfaces arranged on its outer peripheral surface that bear against corresponding inner surfaces of the anti-rotation bridge (16). An opening (28) of the anti-rotation bridge (16) for allowing a passage of a tappet pushrod that is supported on an end of the roller tappet (17) is associated to each reception (18), and a support surface (27) limiting each reception (18) is configured in the anti-rotation bridge (16) for supporting that end of each roller tappet (17) that faces away from the tappet roller.

Abstract: The invention concerns a mounting and anti-rotation device (mounting aid) (1) for roller tappets of a valve train of an internal combustion engine in which gas exchange valves are activated by roller tappets. The roller tappets comprising a substantially cylindrical tappet body are retained in receptions (7, 8) of the mounting aid (1) that is made of plastic. With the help of opposing parallel anti-rotation surfaces that are arranged symmetrically to the longitudinal axis of the roller tappet and are disposed on the end of the tappet body that is oriented away from a roller, the roller tappets are guided secured against rotation in the mounting aid during the operation of the internal combustion engine. This is achieved by the fact that the inner profile of the receptions (7, 8) is matched to the outer profile of the roller tappets. To avoid mixing up the switchable with the non-switchable roller tappets during assembly, the distances between the anti-rotation surfaces on the different roller tappets, and thus also the inner contours of the corresponding receptions (7, 8) are chosen so as to differ markedly from each other. To achieve the correct orientation of the switchable roller tappets, for example, relative to an oil gallery, the anti-rotation surfaces of the switchable roller tappets and the corresponding receptions (8) of the mounting aid (1) are arranged asymmetrically to the longitudinal axis of the tappet body and comprise a groove (32) or a rib (35), respectively.

Abstract: The invention proposes a valve train (1) of an internal combustion engine comprising a tappet (7) and a tappet pushrod (1) that is actuated by said tappet (7), said tappet pushrod (1) being at least partly hollow and comprising on one end (3), a first support (4) for a pressure piston (5) of a hydraulic lash adjuster (6) of said tappet (7).that follows a periodic driving element such as a cam. A second support (9) for a follower member (2) such as a rocker arm is arranged on a further end (8) of the tappet pushrod (1). The first support (4) comprises a passage (10) for hydraulic medium that can be routed out of the pressure piston (5) during operation of the internal combustion engine into an interior (11) of the tappet pushrod (1), a one-way valve means (12) being installed in the tappet pushrod (1) for retaining a hydraulic medium column during a standstill of the internal combustion engine. In this way, an additional reservoir for hydraulic medium is created that serves for the rapid filling of the pressure piston (5) immediately after a re-starting of the internal combustion engine.

Abstract: An oil lubrication and control system, for an engine having cylinder deactivation switching lifters operated at the pressure of the full oil system, is provided with an auxiliary pressure relief valve which opens to control maximum oil pressure in the system whenever the engine speed and temperature conditions lie beyond the ability of the oil pump pressure control unit to maintain the maximum pressure limit. Addition of the auxiliary pressure relief valve allows extended operation of the switching lifters, which are limited by their construction to operation below a prescribed pressure limit. In a preferred embodiment, the auxiliary pressure relief valve is mounted in the engine crankcase in a bore connected directly with the main oil gallery to provide mounting and actuation of the auxiliary pressure relief valve with a minimum of modifications to the engine oil system design.
