Abstract: The invention proposes a valve train 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 an at least indirectly contacting pressure piston (5) of a hydraulic lash adjuster (6) of said tappet (7) that follows a periodic driving element, typically a cam. A second support (9) for a follower member (2), typically 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), wherein a pipette means (12) is installed in the tappet pushrod (1) for retaining a hydraulic medium column during a standstill of the internal combustion engine. Through the pipette means (12) of the invention, an additional volume of hydraulic medium is available for a rapid filling of the reservoir enclosed by the pressure piston (5) with pressure medium after a re-starting of the internal combustion engine, so that a proper lash adjusting operation is guaranteed from the very beginning.

Abstract: Disclosed is a camshaft, especially for an internal combustion engine of a motor vehicle, comprising at least one cam that is provided with cam segments (2, 3), which can be displaced relative to each other. The aim of invention is to create a compact camshaft structure while obtaining or ensuring good and stable guidance between the cam segments (2, 3) that can be displaced relative to each other. Said aim is achieved by placing the ends of the U-legs of the second cam segment (3), which has the shape of a horseshoe and is movable while the other cam segment (2) is connected in a fixed manner to the camshaft, entirely within the outer contour of the basic camshaft material located between the U-legs in the radially deployed position of the second cam segment (3), said U-legs resulting from the horseshoe shape of said cam segment (3) and extending in a free manner at the ends thereof.

Abstract: An actuator for a valve lift control device linearly moves a control shaft to change a valve lift in accordance with an axial position of the control shaft. A first and a second rotation cam integrally rotate around a common rotation axis by transmission of torque, so that a direct acting follower, which includes a first and a contact members, linearly moves with a control shaft. The first and a second rotation cams are respectively in contact with the first and the second contact members via a first and a second contact points. The first contact point is located on the opposite side of the second contact point with respect to the rotation axis. A sum of a first rotation cam lift of the first rotation cam and a second rotation cam lift of the second rotation cam is substantially constant in a predetermined rotation angular range of the first rotation cam and the second rotation cam.

Abstract: A diesel engine intake cam profile creates two intake valve events separated by a short dwell period each engine cycle. A relatively low valve lift during an engine exhaust event allows a portion of the exhaust gas to flow into an intake manifold and mix with intake air. The intake valve is then nearly closed for a dwell period until a normal intake valve opening occurs, drawing the mixture of air and exhaust gas back into the combustion chamber for compression and burning, upon closure of the intake valves.

Abstract: A valve deactivator assembly according to aspects of the present invention includes an inner body member that is slidably disposed in a longitudinal bore defined by an outer body member. Two diametrically opposed pistons are positioned in a transverse bore also defined by the outer body member. A pair of substantially identical latch members are outwardly biased against an inner end of the pistons by a compressed spring. The latch members are generally semi-cylindrical in shape and include flat truncated semi-circular upper and lower surfaces. The pistons apply radially inward force in response to engine oil pressure to adjacent latch member to move the latch member against the bias of the compressed spring to an unlatched position. The periphery of each latch member lower surface provides arcuate shoulder portions that engage angularly separated portions of a latching surface inside the outer body member.

Abstract: A valve timing adjusting apparatus comprises a first rotating body adjusting the opening/closing timing of the intake valves, and a second rotating body adjusting the opening/closing timing of exhaust valves. A first and a second driving force transmitting members respectively have first and second endless members for power transmission. The peripheral shape of the second rotating body comprises a circumferential shape portion and cutoff shape portions whose distance from the center of rotation is smaller than the circumferential shape portion's. When the first and second rotating bodies are assembled to an internal combustion engine, the cutoff shape portions are positioned in such a rotation angle position that the first endless member for power transmission can be inserted into the gap between the first and second rotating bodies.

Abstract: A rocker shaft holder that supports a rocker shaft and a camshaft holder that supports an intake camshaft and an exhaust camshaft in association with the rocker shaft holder are superimposed and connected to each other on the upper surface of a cylinder head, and a fuel pump that supplies fuel at high pressure to an injector is driven by a journal on a shaft end of the exhaust camshaft. The fuel pump is fastened to the cylinder head by means of a bolt; to the integral type camshaft holder, in which a plurality of bearings are integrally connected together via connecting parts, by means of a bolt; and to the rocker shaft holder by means of bolts, and the rigidity of that parts on which the fuel pump is mounted is thereby enhanced to reliably support the camshaft and the rocker shaft.
