    摘要: A main rocker arm which is pivotally mounted on a rocker shaft has one or more sub-rocker arms pivotally mounted thereon. The main rocker arm is arranged to synchronously open and close two poppet valves. Each of the sub-­rocker arms can be selectively locked to the main one by way of hydraulically operated plunger arrangements. The main rocker arm is provided with a roller type cam follower which follows a low speed cam. The sub-rocker arms are provided with followers which engage high or very high speed cams. Lost motion springs which maintain the sub-rocker arms in contact with the cams are mounted on the main rocker arm.

    摘要: In a multi-cylinder internal combustion engine (1), intake air aspirated to a collector (4) from an intake passage (6) of circular cross-section is provided to the cylinders via branch pipes (5A - 5D) connected to the collector (4). The exhaust gas recirculation system has an exhaust gas recirculation pipe (7) which branches off from an exhaust passage (3) and is connected to the intake passage (6). An exhaust gas inlet (8) leads recirculated exhaust gas from the exhaust recirculation pipe (7) substantially tangentially into the intake passage (6). In preferred embodiments, there are two exhaust gas inlets (8,9) 180° apart.

    摘要: A cylinder head (1) of a DOHC internal combustion engine has a plurality of bearing sections which are located in the vicinity of each cylinder of the engine. Each of the bearing sections has a head bolt insertion-hole (16, 17) which vertically extends to pass through the bearing section and is connected with a head bolt hole (18, 19) located therebelow. Furthermore, Y-shaped rocker arms (2, 3) of the end pivot type are disposed on the cylinder head (1) so that each swinging end of the rocker arm (2, 3) for the intake valves (51) and that for the exhaust valves (52) are disposed opposite to each other. Therefore, an angle defined between the stems of the intake and exhaust valves can become small. This can make flatter the inclination of the upper surface of the combustion chamber, thereby contributing to setting the engine in a suitable compression ratio. Additionally, since the distance between the intake and exhaust camshafts (44, 45) can be suppressed relatively short, the lateral width of the cylinder head (1) becomes short.

    摘要: Main and sub-rocker arms (1,2) mounted on a common shaft and pivotally supported on a cylinder head by a pivot formed at the end of an adjust screw (3) which is provided at one of the main rocker arms. The main and sub-rocker arms are motivated by cams suited for low engine speed and high engine speed operation respectively. A hydraulically operated inter­locking device which selectively locks the main and sub-rocker arms to­gether, is controlled by a supply of hydraulic fluid by way of a passage structure (32,33) formed in the adjust screw (3) and a pivot seat (6) in which the pivot is received.

    摘要: A first rocker arm (101) is used to induce valve lift while a second one (102) used to move the valve back to closed position. The rocker arms are arranged to engage the valve top or retainer (114) surfaces at locations offset from the axis of the valve and to induce the valve to rotate during the lift and closing operations. Springs, hydraulic lifters or double adjust screw type arrangements are used to control clearances.
