    摘要: A main rocker arm is supported for swinging motion to operate one of the intake and exhaust valves of an internal combustion engine. A high-speed rocker arm is supported on the main rocker arm for swinging motion according to rotation of a high-speed cam rotating in synchronism with engine rotation. The high-speed rocker arm has a slip surface for engagement with the high-speed cam. The high-speed rocker arm is drivingly connected to the main rocker arm for swinging motion in unison with the main rocker arm when the engine is operating at a high speed. The driving connection is released to permit swinging motion of the main rocker arm according to rotation of a low-speed cam independently of the swinging motion of the high-speed rocker arm when the engine is operating at a low speed. The slip surface of the high-speed rocker arm is made of an alloy tool steel having carbide deposited and dispersed to provide a hardness of HRC55 or more to the slip surface. A hard coat is formed through physical vapor deposition on the slip surface of the high-speed rocker arm.

    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.

    摘要: A variable compression ratio engine. The engine includes a piston disposed in a cylinder bore and constituting a combustion chamber, a variable compression ratio mechanism connected to the piston and causing a top dead center position of the piston to vary, an actuator connected to the variable compression ratio mechanism to actuate the variable compression ratio mechanism, and a controller connected to the actuator to control an engine state and the actuator. The controller performs operations including setting the compression ratio corresponding to a state of the engine, actuating the actuator so that the compression ratio is set, determining whether a state of the engine is either a state allowing actuation of the actuator, or a state limiting actuation of the actuator, and limiting actuation of the actuator in the state limiting actuation of the actuator.
