摘要： Provided is a control apparatus for an internal combustion engine that can suppress deterioration of a catalyst that is ascribable to a control delay of a variable valve operating apparatus when transitioning to a valve stopped state accompanying a fuel-cut operation, or when transitioning from the valve stopped state to a combustion limit operating state. An intake variable valve operating apparatus capable of changing the operating state of an intake valve to a valve stopped state by continuously changing a lift amount and working angle of the intake valve is included. When the temperature of a catalyst is equal to or greater than a predetermined temperature, fuel injection is executed to supply fuel into an exhaust passage during a period in which the operating state of the intake valve transitions to the valve stopped state, during a period in which a fuel-cut operation is executed in the valve stopped state, or during a period in which the operating state of the intake valve transitions from the valve stopped state to a return limit operating state.

摘要： The present invention makes it possible to favorably change valve-opening characteristics of a valve using a simplified configuration without leading to an increase in the number of components and also without causing an increase of friction due to sliding, in a valve operating apparatus for an internal combustion engine in which the valve-opening characteristics of the valve are variable. A changeover mechanism for switching the connection/disconnection of rocker arms disposed between cams and a valve is provided. When a slide pin reaches a displacement end in the retreating direction of changeover pin, the biasing force of a return spring acting on changeover pins is received by an engaging part between a notch part provided in the slide pin and a lock pin in a state separated from a camshaft.

摘要： A variable valve operating device that makes it possible to reduce the loss in driving force transmission from a camshaft to a valve during a valve lift is provided. The rotary motion of a drive cam is transmitted to a swing member via intermediate rollers. A coupling member couples the intermediate rollers, to a swing fulcrum that is fastened to a control shaft. The swing fulcrum is positioned eccentrically to the center of the control shaft. Further, when the control shaft is positioned at a predetermined rotation position, the swing fulcrum is positioned so that the control shaft is placed between the swing fulcrum and the intermediate rollers. Preferably, the swing fulcrum, the control shaft, and the intermediate rollers are aligned.

摘要： Disclosed is a variable valve mechanism for an internal combustion engine. The variable valve mechanism accurately adjusts the valve operating angle although its structure is simple. The variable valve mechanism includes a control pin 48, which is inserted into a pin insertion hole 38 in a control shaft 16; a bearing hole 44, which is formed in a control member 26; and an adjustment pin 50, which is rotatably supported by the bearing hole 44. The adjustment pin 50 comes into surface contact with the control pin 48 to inhibit the control member 26 from rotating relative to the control shaft 16. The valve operating angle is adjusted by replacing the adjustment pin 50 with another having a different dimension B. Such adjustment pin replacement changes the distance A between the center line of the bearing hole 44 and the center line of the control pin 48, thereby changing the relative angle θ between the control shaft 16 and control member 26. When the adjustment pin 50 rotates within the bearing hole 44, the surface contact between the adjustment pin 50 and control pin 48 is maintained irrespective of the magnitude of the relative angle θ.
