    摘要: A multi-valve engine of the type having a line of cylinders, intake and exhaust camshafts, and rocker arms for operatively connecting valves to the camshafts includes a first valve group of three valves consisting of either intake valves or exhaust valves and a second valve group consisting of the other of either intake valves or exhaust valves. Each of the valves of the first valve group is oriented such that a valve stem thereof is inclined outwardly to one side of the line of cylinders, while each of the valve of the second valve group is oriented such that a valve stem thereof inclines outwardly to an opposite side of the line of cylinders. First hydraulic lash adjuster means for a centrally-located valve out of three valves of the first valve group is positioned closer to a bore center of the cylinder than the centrally-located valve, or on a delay side in the rotational direction of the camshaft. Second and third hydraulic lash adjuster means for side-located valves of the three valves of the first valve group are positioned farther from the bore center than the side-located valves, or on a leading side in the rotational direction of the camshaft.

    摘要: A power transmission system for a vehicle has a first power transmission path having a forward-reverse shift mechanism and a reduction gear, a second power transmission path having an infinitely variable gear, and a path switching mechanism which switches the power transmission path between the first and second power transmission paths according to the running condition of the vehicle. The infinitely variable gear is a toroidal speed change mechanism having an output disk fixed to the output shaft of the power transmission system, an input disk which can be displaced in the axial direction of the output shaft and a roller which is in contact with both the input and output disks to rotate about an axis in response to rotation of the input disk and transmit rotation of the input disk to the output disk, the transmission ratio of the toroidal speed change mechanism being changed by changing the inclination of the axis about which the roller rotates.

    摘要: A power transmission device for a vehicle comprises a first power transmitting path for transmitting engine output to a wheel side via a reduction gear, a second power transmitting path for transmitting engine output to the wheel side via a stepless speed change gear mechanism, a path switching clutch for switching between the paths to transmit by one of the paths, a switch-over control part for controlling switch-over operation of the clutch according to a driving condition of the vehicle, and a rotational condition abrupt change restraining part for restraining an abrupt change of a rotational condition of an engine output shaft at switch-over between the paths. The restraining part adjusts to conform rotating speeds of the input and output sides of the clutch to each other at switch-over of the clutch, or conform output torque to the wheel side between before and after switch-over of the clutch. Thus, an abrupt change of rotation of the engine output shaft is restrained to prevent a shock owing to switch-over, and the durability of a friction element is enhanced.

    摘要: A hydraulically operated stepless transmission has a first power flow path established so as to include a torque converter and a reverse and reduction gear and a second power flow path established so as to include a stepless transmission gear. The first and second flow paths are selectively available. A hydraulic control circuit, including at least one oil pump, causes a decrease in quantity of a lubrication oil delivered to the stepless transmission gear while the first power flow path is established, and causes a decrease in quantity of a working oil delivered to the torque converter while the second power flow path is established.

    摘要: A diesel engine intake system including a timing valve which is positioned in the intake system in engine starting and warming-up periods under a cold engine condition. The timing valve is opened in the final period of the intake stroke so that a strong suction pressure is produced in the combustion chamber before the timing valve is opened. When the timing valve is opened, the intake air as rushes into the combustion chamber at a high speed, whereby the intake air is compressed under the inertia of the high speed flow to thereby increase the temperature of the intake air. The engine is also provided with a blow-by passage and an exhaust gas recirculation passage, both opening to the intake passage upstream of the timing valve, so that it is possible to prevent the blow-by gas and the recirculated exhaust gas from being drawn under the suction pressure when the timing valve is closed.
