  • Patent number: 8689751
    Abstract: The disclosed structure achieves a desired balance between higher-rigidity and weight saving in a connection-type rocker arm which integrally rocks a plural of arm portions. The rocker arm has a plurality of arm portions integrally formed on a swinging base end side of the rocker arm which are forked and extend towards a swinging end of the rocker arm, a connecting portion which integrally connects each swinging end of the arm portions, and a concave thinning portion which overlaps a swinging trajectory of the connecting portion, when viewed in the axis direction of the pivot shaft of the rocker arm.

  • Patent number: 8584645
    Abstract: A vehicle includes a variable intake pipe length device capable of adjusting the length of an intake pipe according to the condition of an engine, the intake pipe being provided in an intake passage for inducing air from an air cleaner box to an intake port of the engine, the intake pipe including a fixed funnel and a movable funnel movable relative to the fixed funnel by a driving force of an actuator. A rotating pipe as a part of the intake pipe is rotationally driven by the actuator, and the movable funnel is moved by rotating the rotating pipe, thereby varying the length of the intake pipe.

  • Patent number: 8413623
    Abstract: An internal combustion engine is equipped with a variable valve control system which is operable to selectively actuate an engine valve using one of two cams of a camshaft, by sliding a rocker arm in the axial direction of a rocker-arm shaft. The system is capable of restricting the axial-direction movement of the rocker arm within a predetermined range, using a simple structure without unduly increasing the number of component parts. Position-restriction portions are formed in a rocker arm, and abut on a trigger arm to restrict sliding movement of the rocker arm within a predetermined amount, when the trigger arm is disengaged from the rocker arm.

  • Patent number: 8205588
    Abstract: In an internal combustion engine, a variable valve-actuating mechanism includes a trigger pin operable to permit axial movement of a rocker arm concurrently with a axial movement of a rocker arm shaft. A retention member has an insertion aperture formed therein, in which the trigger pin is inserted, and which slidably supports the trigger pin in the inserting direction. The trigger pin includes upper and lower expanded portions disposed on both sides thereof in the inserting direction. The upper and lower expanded portions of the trigger pin are operable to disable sliding motion of the trigger pin, relative to the retention member, beyond a predetermined range. The upper and lower expanded portions allow the trigger pin to be integrally assembled in the insertion aperture of the retention member, so as to be selectively retained therein.

  • Patent number: 8136492
    Abstract: An internal combustion engine includes a variable valve control system which is operable to switch actions of an engine valve by slidably moving a rocker arm in the axial direction of a rocker-arm shaft, and which is capable of removing a restriction on the sliding movement of the rocker arm at accurate timings while employing a simplified configuration. When a trigger arm swings by a predetermined amount to the opposite side of a rocker arm, a left-hand engagement nail in engagement with an engagement groove disengages from the engagement groove, but a right-hand engagement nail still engages with an engagement groove. The left-hand engagement nail is placed on top of a left-hand deck-like portion. After that, when an action of the rocker arm makes the trigger arm further swing to the opposite side of the rocker arm, the right-hand engagement nail disengages from the engagement groove.

  • Patent number: 7980213
    Abstract: The invention provides an internal combustion engine equipped with a variable valve control system which switches the actions of an engine valve by sliding a rocker arm in the axial direction of the rocker arm shaft, while enabling the restriction on the sliding movement of the rocker arm to be removed in accordance with the timings of the actions of the rocker arms irrespective of the engine speed. The internal combustion engine includes an actuator that moves a rocker arm shaft in its axial direction, a trigger arm that engages with a rocker arm to prohibit the sliding movement of the rocker arm, and a trigger pin which is configured to be activated by an axial movement of the rocker arm shaft to bring the trigger arm into action, and to disengage the trigger arm from the rocker arm.
