    Abstract: A driving arrangement for a motor vehicle having a transversely disposed V-type four camshaft internal combustion engine. The camshafts are all driven in timed relationship with the crankshaft with a first flexible transmitter being operative to drive the intake camshafts of each cylinder bank at the same end of the engine from the crankshaft. The exhaust camshafts of each bank are driven by the intake camshafts at the opposite end of the engine.

    Abstract: An autotensioner and a tension adjustor are provided with a detector for detecting the timing for belt replacement. The bottom end of a metal ring of an oil seal for closing a top opening of a cylinder is exposed. A guide flange slidable along the inner surface of the cylinder is mounted on a pushrod. Due to contact of the guide flange with the metal ring, the limit position of the forward stroke of the pushrod is detected and the belt replacement timing is notified.

    Abstract: A personal watercraft features a four-cycle engine. The four-cycle engine has an intake valve and an exhaust valve. The intake valve and the exhaust valve are controlled through a use of a cam drive arrangement. The cam drive arrangement is contained within a protective housing. A number of waterjackets are provided to the housing to control the temperature within the housing. In addition, the watercraft features a protective housing in which a starter motor is mounted to the cylinder block. The housing features two members that can be mounted to the cylinder block together while one member can be removed for access to the starter motor.

    Abstract: Sprockets are fixed to ends of camshafts supported in a cylinder head via camshaft holders. A timing chain is wrapped around these sprockets. The relief oil from a hydraulic control valve for controlling a variable valve operating characteristic mechanism passes through an oil passage formed in the plane in which the cylinder head and the camshaft holder are joined and flows out of an oil drain hole, thus lubricating the section where the sprocket is meshed with the timing chain. The section where the sprocket of the camshaft is meshed with the timing chain can thereby be lubricated reliably by a simple structure.

    Abstract: In a valve-operating device with a breather system in an engine, in which a breather passage is defined in a cam shaft, a bearing cap is detachably secured to the engine body for supporting an outer peripheral surface of one end portion of the camshaft with a bearing. A breather chamber is provided in the bearing cap in order to communicate with the outlet of the breather passage. A pipe-connecting portion is integrally formed on an outer peripheral surface of the bearing cap; and a breather pipe connected to an intake system is connected to the pipe-connecting portion. Thus, a blow-by gas can be drawn through the breather passage in the valve-operating camshaft to the outside by utilizing a portion of a valve-operating camshaft supporting structure. It is thus possible to simplify the structure of the valve-operating device with the breather system.

    Abstract: A tensioner for a camshaft driving chain (a plunger device 17 shown in the first embodiment of the invention) and a hydraulic control valve 21 are disposed close to each other. An oil passage 31 for supplying an oil pressure to the tensioner is caused to branch off from a downstream side of an oil filter 27 provided at an inlet port 28 of the hydraulic control valve. With this construction, the arrangement of the oil passage can be simplified, and therefore not only can man hours required for forming the oil passage be reduced, but also the number of components required can also be reduced by commonizing the oil filter. Accordingly, it is possible to provide an improved assembling arrangement for a tensioner and a hydraulic control valve in an internal combustion engine without involving an increase in production costs.

    Abstract: A small planing watercraft including a hull, a propulsion unit mounted on the hull and a high RPM—high output engine for driving the propulsion unit, wherein the engine includes at least one intake valve and an intake valve timing control system for advancing the opening and closing of the intake valve when the watercraft is operating below a predetermined speed corresponding to a velocity at which the watercraft transitions from non-planing to planing motion. The engine may also include a long air intake passage for low-speed operation and a short air intake passage for high-speed operation, with an air intake control valve in the short air intake passage that is closed when the watercraft is operating below the predetermined speed. The engine may also include an exhaust control valve for constricting the exhaust passage, and a system for at least partially closing the exhaust control valve when the watercraft is operating below the predetermined speed. The invention increases the lower RPM output of a high RPM—high output engine to enable faster transition of the watercraft between non-planing and planing operations. Engine intake air flows over the intake valve timing control to provide a cooling effect.
