摘要： In an internal combustion engine of variable compression ratio type, a piston control mechanism is employed which comprises a lower link rotatably disposed on a crank pin of a crankshaft of the engine, an upper link having one end pivotally connected to the lower link and the other end pivotally connected to a piston of the engine, a control link having one end pivotally connected to the lower link; and a position changing mechanism which changes a supporting axis about which the other end of the control link turns. When the piston comes up to a top dead center, a compression load is applied to the control link in an axial direction of the control link in accordance with an upward inertial load of the piston.

摘要： A valve operation changing system of an internal combustion engine, comprises a rocker arm (3, 3') to operate an intake or exhaust valve (2, 11), and a control device (19A, 19B, 22, 23, 24, 25, 26) for axially moving the rocker arm so as to selectively cause the rocker arm (3, 3') to engage with first or second cam (12, 13; 45A, 45B) in accordance with an engine operating condition. The control device includes an actuator having first and second hydraulic pressure chambers (19A, 19B; 50a, 50b) whose pressures move the rocker arm (3, 3') to engage with the first and second cams (12, 13; 45A, 45B), respectively. A flow direction changing valve (23) is provided to selectively supply the first or second hydraulic pressure chambers (19A, 19B; 50a, 50b) with oil from an oil pressure source (21), in accordance with the engine operating condition. A stopper device (26) is provided to restrict the movement of the rocker arm (3, 3'). Additionally, a timing lifter (25) is provided to release the rocker arm (3, 3') from the restriction by the stopper device in timed relation to the rotation of the first and second cams (12, 13; 45A, 45B), thereby accomplishing the axial movement of the rocker arm (3, 3') at a predetermined suitable timing and at a higher speed.

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： An engine intake control apparatus for an engine that comprises at least one combustion chamber operatively connected to an intake port and an intake valve associated with each intake port, wherein the intake valve is adapted to open and close the intake port is disclosed herein. The intake control apparatus comprises a variable valve operating mechanism and a controller. The variable valve operating mechanism is configured and arranged to selectively change a valve closing timing and a valve lift amount of the intake valve. The controller is configured and arranged to control the variable valve operating mechanism when the engine is in a low load condition. 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.

A piston pin connects the piston to an upper link, which is connected to a lower link by an upper link pin. A crank pin of the crankshaft rotatably supports the lower link thereon. A control link pin connects the lower link to one end of a control link, which is connected at another end to the engine block body by a control shaft. The upper link has an upper link axis that forms an angle with the cylinder axis, as viewed along a crank axis direction of the crankshaft, such that the angle reaches a minimum when a crank angle of the engine is within a range where the bottom end of a piston skirt is positioned below a topmost part of the bottom end of the cylinder liner.

The crankshaft (33) includes: a journal (33A) as a rotation center; a crank pin (33B) that is located eccentrically with respect to the journal (33A) and rotates integrally with the journal (33A), the crank pin (33b) connecting the piston (2) to the crankshaft (33); and a counter weight (33C) that is located eccentrically with respect to the journal (33A) in a direction opposite to the crank pin (33) and rotates uniformly with the journal (33A). A cutout (11) through which the counter weight (33C) passes is formed in a wall (1) of a cylinder bore that accommodates the piston (2) so as to be free to move reciprocally along the wall (1). As a result, the bottom dead center position of the piston can be lowered, and the overall height of the engine can be decreased.
