摘要： In a variable valve timing mechanism, a valve-lifting cam member is fitted, slidably in tile circumferential direction, onto a camshaft that is driven to rotate in synchronization with a crankshaft of a four-stroke cycle internal combustion engine. An eccentric collar is set between a driving collar fixed on the camshaft and the valve-lifting cam member. A driving projection is formed in the driving collar and engages with one of sandwiching portions of the eccentric collar. A driven protrusion is formed in the valve-lifting cam member and engages with another one of the sandwiching portions of the eccentric collar. A linkage mechanism includes the eccentric collar, the drive, and the driven protrusions. The variable valve timing mechanism adjusts the timing of opening and closing of the valve while the rotational phase of the valve-lifting cam member is cyclically varied relative to the camshaft by the eccentricity of the eccentric collar.

摘要： A cooling control unit for a water-cooled multi-cylinder internal combustion engine having a cylinder deactivation mechanism for controlling the flow of coolant to prevent the internal combustion engine from being incompletely warmed up when the internal combustion engine returns to its operating condition with all of the cylinders being activated. A communicating passage communicates with a normally activated cylinder coolant jacket as a coolant passage formed for normally activated cylinders and a deactivation-programmed cylinder water jacket as a coolant passage formed for the deactivation-programmed cylinders to communicate with each other, and through which the coolant flows. A bypass passage diverges from the communicating passage and bypasses the deactivation-programmed cylinder coolant jacket. A diversion control valve is provided in a diversion section where the bypass passage diverges from the communication passage. A control member controls the diversion control valve in accordance with the operating state of the internal combustion engine.

摘要： There is provided an engine for a small vehicle where driven sprockets, around which a cam chain for transmitting power from a crankshaft is wound, are provided at one end of camshafts that form a part of a valve system provided with hydraulic valve-operation mode changing mechanisms; and a valve-moving hydraulic pressure control device, which controls hydraulic pressure applied to the valve-operation mode changing mechanisms, is provided in the engine body. In the engine, it is possible to increase the degree of freedom in disposing the oil passage between the valve-operation mode changing mechanism and the valve-moving hydraulic pressure control device while avoiding the increase in the number of parts and assembly man-hours. A valve-moving hydraulic pressure control device is mounted on the side surface of the engine body on the side opposite to a cam chain in an axial direction of a camshaft.

摘要： An engine includes engine valves disposed on intake and exhaust sides of a combustion chambers with a valve operating device for opening and closing the engine valves and an engine valve disabling mechanism for disabling opening and closing movement of the engine valves in response to hydraulic pressure. An oil pump is disposed in a lower portion of the crankcase, for supplying hydraulic pressure to the engine valve disabling mechanism. A hydraulic pressure control valve controls the supply of hydraulic pressure to the engine valve disabling mechanism depending on a vehicle operating state. An oil passage extends to the hydraulic pressure control valve and can easily be formed without affecting mounts for functional components. A pipe for delivering working oil from the lower portion of the crankcase to the hydraulic pressure control valve is disposed on a front surface of the engine.
