摘要： In a valve mechanism of an internal combustion engine having a cylinder with a pair of air-intake valves, the number of operation modes of the air-intake valves in accordance with engine operation region is increased to improve combustion nature in a combustion chamber and engine output and to miniaturize the valve mechanism. The valve mechanism comprises first and second drive rocker arms operatively connected with the respective air-intake valves, first, second and third free rocker arms coming into contact with first, second and third operation cams having profiles for making the air-intake valve perform opening-closing motion. The drive rocker arms are connected and disconnected with the free rocker arms in accordance with engine operation states, thereby a state in which both the air-intake valves are closed for pause, a state in which one of the air-intake valves performs opening-closing motion with a small lift and another air-intake valve is closed for pause, a state in which both the air-intake valves perform opening-closing motion with a small lift, or a state in which both the air-intake valves perform opening-closing motion with a large lift is obtained. Pipe members with fan-shaped cross-section are inserted in a rocker arm shaft to form oil-pressure supply passages for switching over the connection states.

摘要： A lubricating oil discharge port is provided that is improved so well that a quick supply of lubricating oil is not disturbed and that film lubrication is not lost when the engine is started. The lubricating oil discharge port 18a for allowing lubricating oil to flow out of a lubricating oil passage 18 in which an oil pressure source is provided at a lower portion thereof into a bearing bore 12 for a camshaft 10 of an engine is made to open in a top surface of a boss 19 provided so as to protrude from a bottom of a recessed well 15 acting as a lubricating oil reservoir provided in an inner circumferential surface on a lower side of the camshaft bearing bore. With this construction, the level of lubricating oil retained in the recessed well formed in the lower side of the bearing hole can be raised considerably high, and therefore even in an operating condition where the discharge pressure of an oil pump is not sufficiently increased resulting immediately the engine is started, the lubrication of the camshaft can be effected with lubricating oil retained in the lubricating oil reservoir.

摘要： In a variable stroke engine comprising a plurality of links (60, 61) connecting a piston (11) with a crankshaft (30), a control member (65) disposed on an engine main body so as to be moveable in two directions over a prescribed range relative to the engine main body, a control link (63) connecting one of the plurality of links with the control member and an actuator (AC) for displacing the control member, the actuator comprises a ratchet mechanism that utilizes a force transmitted from the piston to the control member as an actuating force for the control member. By providing a spring member (73, SP, 121) that applies a biasing force to the control member, an appropriate actuating force can be applied to the control member in either direction.

摘要： A rocker arm (63) is provided with a valve connecting portion (63a) into which tappet screws (70) abutting against a pair of engine valves (19) are screwed so that their advance/retract positions can be adjusted, and the rocker arm (63) has a cam abutting portion (65) which abuts against a valve operating cam (69) and is interlocked and connected to the engine valves (19). The rocker arm (63) turnably connects to one end of a first link arm (61) turnably supported at a fixed position of an engine body and to one end of a second link arm turnably supported by a displaceable movable support shaft (68a). The rocker arm (63) is formed so that the valve connecting portion (63a) has a larger width in a direction along a rotating axis of the valve operating cam (69) than in the remaining part. This enables the lift amount of the engine valves to be continuously varied. It is also possible to reduce the size of the system, while ensuring follow-up ability of the opening/closing operations.

摘要： In an engine in which a lift amount of a valve can be changed continuously, an engine valve operating system including a valve lift-changing mechanism is capable of increasing and decreasing the lift amount of the valve without changing an opening angle for the valve and capable of decreasing a tappet clearance in accordance with a decrease in lift amount of the valve. Thus, it is possible to prevent the ratio of the tappet clearance to the lift amount at a low valve lift from being increased to minimize the influence of the dispersion of the tappet clearance and to reduce the seating speed of the valve at the low valve lift to prevent the generation of a noise. It is also possible to prevent a reduction in performance of the engine at a high valve lift due to the dispersion of the tappet clearance and to decrease the seating noise of the valve at the low valve lift.
