    摘要: A valve characteristics varying mechanism for a valve operating device has a valve operating cam supported by a camshaft and a drive mechanism for oscillating an interlinking mechanism about the camshaft, the interlinking mechanism oscillating the valve operating cam by a drive cam integral with the camshaft. An engine valve starts to open and close at a cushioning section of the valve operating cam, and the drive mechanism oscillates the valve operating cam through the interlinking mechanism to control an opening and closing time of the engine valve. A cam mountain section of the drive cam has constant speed sections at which a lifting speed is constant, and the constant speed section is set across an angle width where an opening time is included at the most advanced angle position at the opening time of the engine valve and where an opening time is included at the most delayed angle position of the opening time.

    摘要: The present invention provides a variable valve mechanism that includes a drive cam for supplying a driving force, a link mechanism that opens and closes a valve by transmitting the driving force to the valve and has a plurality of rocking levers connected in sequence by respective joints so as to be relatively rotatable, and a variable mechanism that changes an opening and closing amount of the valve by displacing the link mechanism. One of the rocking levers of the link mechanism is provided with a length adjustment mechanism for adjusting a length of the one rocking lever in which the length adjustment mechanism is provided, and the opening and closing amount of the valve can be adjusted by adjusting the length using the length adjustment mechanism.

    摘要: While an operating angle or a lift of an engine valve (211) is modified within a predetermined operating angle range or lift range, variation in an opening timing of the engine valve (211) is suppressed by displacing a rocker shaft (216b) relative to a drive shaft (213) such that an opening timing variation of the engine valve (211) accompanying angular variation in a straight line linking a center of the drive shaft (213) and a center of the rocker shaft (216b) and an opening timing variation of the engine valve (211) accompanying variation in a distance between the center of the drive shaft (213) and the center of the rocker shaft (216b) cancel each other out.

    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.
