摘要： To provide a variable valve operating apparatus for an internal combustion engine which can reduce a range where heat treatment is required, thereby favorably suppressing distortion which occurs in a camshaft during heat treatment, to a low level. A changeover mechanism is provided which includes a slide pin which is adapted to move within a predetermined reciprocating range thereby switching between operational states of a variable mechanism, and a guide rail provided in an outer peripheral surface of the camshaft and guides the movement of the slide pin from one end to a remaining end of the reciprocating range. A projection part which is engageable with the guide rail is provided in the slide pin. Restriction means which performs at least one of a restriction of contact between a top surface of the projection part and a bottom surface of the guide rail opposing the projection part, and a restriction of movement of the slide pin beyond a distance from the above-described one end to the above-described remaining end.

摘要： Provided is a variable valve operating apparatus for an internal combustion engine, which can switch, based on an actuation of a single actuator, operating characteristics of valves for a plurality of cylinders collectively and smoothly using a rigid member, while suppressing an increase in wear of a guide rail and reducing the number of delay mechanisms.A changeover mechanism to switch operating characteristics of valves for each cylinder of first and second cylinder groups is provided. The changeover mechanism includes link shafts as a rigid member which is displaced when being engaged with a helical guide rail as a result of the actuation of an electromagnetic solenoid. The changeover mechanism includes a delay mechanism, which delays the displacement of the second link shaft in a cylinder in which the valves are lifting when the electromagnetic solenoid is actuated, at some point in the link shafts between the first cylinder group and the second cylinder group.
