    Abstract: In a case member mounting structure for mounting a chain case to an engine body, the chain case is fastened to the engine body by a number of bolts applied along the outer edges thereof and by bolts applied to portions in a central region thereof. The chain case has a plurality of central fastening boss portions in a central region of the inner wall surface, and bolt fastening holes are formed in the respective central fastening boss portions. An annular connection wall is formed in a projecting fashion to connect the central fastening boss portions such that the chain case is affixed to the engine body by putting the connection wall and the central fastening boss portions in abutment with the engine body. As a result, it is possible to fasten the chain case with fewer fastening bolts, enhance the rigidity of the central region of the chain case and prevent its vibrations.

    Abstract: An adjustable cam shaft sprocket for allowing small adjustments to a cam shaft. The adjustable cam shaft sprocket comprises an inner member and an outer member, the inner member being placed concentrically within said first circular member and held in place by a fastener. A series of openings located at the perimeter of the inner member and outer member are arranged such that only one pair of openings between the inner member and the outer member are aligned for each hole alignment. A shear pin is inserted through the aligned pair of openings to prevent the inner member from rotating with respect to the outer member. A small adjustment to the cam shaft is achieved by removing the shear pin, rotating the inner member with respect to the outer member so that a second pair of openings is aligned, and re-inserting the shear pin.

    Abstract: The combination comprises a valve controlled piston and cylinder internal combustion engine and a coolant system. The engine has an output shaft and a camshaft driven by the output shaft. The system includes a coolant flow path which passes through the engine in cylinder cooling relation and thereafter through a cooling zone. The system includes a coolant pump comprising a pump housing within the flow path, an impeller rotating structure, a pump impeller, and a damper assembly. The rotating structure is mounted directly to the camshaft so as to be rotatably driven thereby about an axis concentric to a rotational axis of the camshaft. The damper assembly is disposed within the pump housing and is rotatable to dampen torsional vibrations of the camshaft.

    Abstract: A method and a device for reducing the vibrations of a control chain in a camshaft drive of an internal combustion engine. At least one engine parameter is measured that is indicative of the vibrational state of the engine. The at least one engine parameter is used to determine the vibrational state and to adjust the tension of the control chain. Thus, the built-up of resonances and of strong vibrations may be avoided.

    Abstract: The reciprocating engine comprises a rocker valve gear, pistons (1) which are fastened to a connecting rod (2) and connected by crankshaft journals (3) to a crankshaft (4), a balancer (5), and a camshaft (10) which is driven by the crankshaft (4) and in turn actuates rockers (11), the mentioned elements being arranged in a crankcase having a cylinder head (24) and cylinder head cover (14). For substantially easier assembly and maintenance, the cylinder head (24) is provided with integrally cast or screwed-on receivers (16) serving for the attachment of the hollow camshaft (10) without requiring separately fastened bearing blocks. Correspondingly, the cylinder head (24) comprises further integrally cast or screwed-on receivers (15, 15-A, 25) which serve for the attachment of the hollow rockers (11) without requiring separately fastened bearing blocks. According to another embodiment of the invention, the camshaft (10), the tensioning wheel (7), and the counter-rotating balancer (5) are driven by the camshaft (4) through a single chain (8) arranged in line with the camshaft, thus allowing a compact construction.

    Abstract: In a fuel injection type multicylinder engine, both the mounting of a camshaft angle sensor, which is operable in response to angular movement of a valve driving camshaft to detect a timing of injection of fuel injected from a fuel injection valve, on the engine and maintenance of the resulting engine are improved. A camshaft angle sensor S is operable in response to an angular movement of an exhaust-side valve driving camshaft and is mounted on the engine E at one side surface exposed from the lower portion of a frame F. Mounting of a cam pulsar of the angle sensor S from the side of the frame F and the maintenance is possible without being obstructed by the frame F.

    Abstract: The object of the present invention is to facilitate an appropriate oil supply to the tensioner without a complex apparatus. A valve chamber 3A is formed in a cylinder head 3 which is connected to a cylinder block 2. An opening 23—for discharging the oil in the valve chamber 3A into a chain case 6 which is placed on the side of the cylinder block 2—is formed on a chain case mounting surface 20. Inside the chain case 6 on the chain case mounting surface 20 of the cylinder block 2 are placed a timing chain 15 and a tensioner 30 for applying tension to the timing chain 15. An oil dropping rib 24 for guiding the oil discharged through the opening 23 to the tensioner 30 is provided on the chain case mounting surface 20.
