    摘要: A lower link for a piston crank mechanism of an internal combustion engine includes an upper section, a lower section, and a crank pin bearing section disposed between the upper section and the lower section, and mounted on a crank pin of a crank shaft. One of the upper section and the lower section is formed with a bolt inserting hole. The other of the upper section and the lower section is formed with an internal thread portion including an open end. One of the bolts passes through the bolt inserting hole, is screwed into the internal thread portion, and includes an end bared from the open end which is formed in a surface perpendicular to a bolt center axis. The other of the upper section and the lower section includes a recessed portion formed in the surface to divert a stress transmitting path.

    摘要: In an internal combustion engine, a piston reciprocating in a cylinder and a crankshaft are linked with each other by a piston-crank linking mechanism. The crankshaft includes a counterweight. When the piston is located in the proximity of a bottom dead center, an outermost portion of the counterweight crosses an imaginary extension line extended from a piston pin in an axial direction of the piston pin.

    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.

    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.
