摘要： 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.

摘要： 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.

摘要： 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.

摘要： A gear having a high fatigue strength can be produced relatively inexpensively. The gear is produced by plastic working using a steel material containing C.ltoreq.0.01 wt %, Si.ltoreq.1 wt %, 0.05 wt %.ltoreq.Mn.ltoreq.0.5 wt %, P.ltoreq.0.1 wt %, S.ltoreq.0.03 wt %, 0.02 wt %.ltoreq.sol.Al.ltoreq.0.1 wt %, 0.8 wt %.ltoreq.Cu.ltoreq.1.7 wt %, and 0.02 wt %.ltoreq.Ti.ltoreq.0.1 wt %, the balance being Fe and inevitable elements. The gear is subjected to soft nitriding, serving as artificial aging, after a solution treatment. The resulting gear has a sufficiently deep, surface hardened layer. Further, the gear may be produced inexpensively since the simultaneous performance of the artificial aging and soft nitriding saves energy.
