摘要： A valve operating mechanism for operating a pair of valves of an internal combustion engine, includes a camshaft rotatable in synchronism with rotation of the internal combustion engine and having a first low-speed cam, a second low-speed cam, and a high-speed cam which have different cam profiles, respectively, the first and second low-speed cams being disposed one on each side of the high-speed cam, a rocker shaft, and first, second, and third rocker arms rotatably mounted on the rocker shaft and held in sliding contact with the first low-speed cam, the second low-speed cam, and the high-speed cam, respectively, for operating the valves according to the cam profiles of the cams. A selective coupling is operatively disposed in and between the first, second, and third rocker arms for selectively interconnecting the first, second, and third rocker arms to allow angular movement thereof in unison and disconnecting the first, second, and third rocker arms to allow separate angular movement thereof.

摘要： Blow-by gas passages are formed on one side of the cylinder block and cylinder head of an internal combustion engine and spaced longitudinally of its crankshaft. The passages extend from the interior of the crankcase to a location above an upper face of the cylinder head, one of the passages being provided with a mounting port for an oil separator. The other blow-by passage is also connected to the separator, and the separator is connected to the intake system of the engine.

摘要： In an internal combustion engine, an intake manifold has a main distributing chamber and an auxiliary distributing chamber disposed to overlap with the main distributing chamber at a location inward thereof. The main distributing chamber is divided by a partition wall into a primary distributing chamber and a secondary distributing chamber. The partition wall has a boss through which is formed an intake guide passage having one end opening in the auxiliary distributing chamber and directed toward a substantially central location of the chamber. The primary distributing chamber, the secondary distributing chamber and the intake guide passage leading to the auxiliary distributing chamber have respective mixture-inlet ports opening in a carburetor-mounting surface formed on the outer surface of the intake manifold and arranged thereon in a compact array. Thus, the intake guide passage has a simplified configuration, and also the intake manifold can have a compact size.

摘要： A control system for a variable valve actuating mechanism for an internal combustion engine for varying the lift or timing of intake or exhaust valves in response to engine operating conditions. The control system includes sensors for detecting the pressure in the combustion cylinder and the temperture at the mounting seat of the spark plug. A warning device and fail safe conditions can be activated when an abnormal condition is detected by one of the sensors.

摘要： A valve operating mechanism for an internal combustion engine having a pair of intake valves or exhaust valves in each cylinder with a first and a second rocker arm corresponding to the pair of valves and a cam for pivoting the first rocker arm. The rocker arms are provided with a connecting mechanism having a piston assembly which is movable between a position in which both said rocker arms are connected and a position in which both said rocker arms are disconnected from each other whereby either both valves of the pair or only one valve may be selectively actuated. A trigger member in the first rocker arm selectively restricts the movement of the piston and a timing cam engages and actuates the trigger member.
