摘要： A valve opening control device for use with an internal combustion engine having cam-operated cylinder valves comprises a cam-like member having a cylindrical surface concentric with a shaft about which the member rotates and a cam-like section extending tangentially therefrom. The control device shaft is positioned parallel to and adjacent a rocker arm shaft or otherwise perpendicular to the axis of travel of the cylinder valve and/or the plane defined by such axis of travel and the plane of travel of a cylinder valve rocker arm for such valve. The valve opening control device transmits an opening force from the rotating engine camshaft for a distance which is progressively proportional to the distance the valve lifter travels in response to the rotating engine camshaft.The amount of rotational displacement of the control device is regulated by a hydraulic valve lifter, the effective length thereof being regulated by fluid pressure such that a higher fluid pressure increases the effective length thereof, causing the cylinder valve to be open through a larger degree of camshaft rotation and for a greater maximum distance. This fluid pressure is regulated indirectly by the relative position of the engine throttle, so that higher throttle settings increase the fluid pressure to the hydraulic valve lifter to cause the cylinder valve to be open a greater distance and for a longer period of time.

摘要： A valve operating device that opens and closes a valve of an internal combustion engine by driving a valve stem in an axial direction includes a rocker cam that rocks in accordance with a rotation of a drive shaft and has a driving cam portion and a lift restricting cam portion; a cam follower that lifts the valve by contacting the driving cam portion slidingly; and a restricting member that prevents the cam follower from separating from the driving cam portion in cooperation with the lift restricting cam portion. A gap is formed between the restricting member and the rocker cam in a state where the cam follower is in contact with the driving cam portion and disappears such that the restricting member and the rocker cam come into contact with each other only when the cam follower separates from the driving cam portion.

The valve closing timing is determined such that an actual compression ratio of the engine is reduced relative to the actual compression ratio when the engine is operating in a high load condition. The valve lift amount is smaller when the engine is in the low load condition relative to the valve lift amount when the engine is in the high load condition. A method for controller an engine is also disclosed.

摘要： A paired counterweights of a crankshaft have projected inner surfaces which protrude toward each other defining a given space therebetween. A plurality of links are arranged to convert a reciprocating motion of a piston to a rotational motion of the crankshaft. One of the links is pivotally connected to other links through link connecting portions and swingably disposed on a crank pin of the crankshaft so that upon rotation of the crankshaft, a peripheral portion of the link passes through the given space. At least one of the link connecting portions is placed within an imaginary circle which would be described by a radially innermost part of the projected inner surfaces of the paired counterweights when the paired counterweights turn about an axis of the crank pin.

摘要： An internal combustion engine has an intake valve control device for controlling at least intake valves. The control device comprises a first mechanism which varies a working angle of the intake valve; a second mechanism which varies an operation phase of the intake valve; and a control unit which controls both the first and second mechanisms in accordance with an operation condition of the engine. The control unit is configured to carry out controlling variation in the open timing of the intake valve effected by the first mechanism to be larger than variation in the open timing of the intake valve effected by the second mechanism.
