Abstract: Provided is a heat treatment method for a cam piece, and the cam piece has an insertion hole into which a cam shaft is inserted, a base portion configuring a base circle of a cam, and a nose portion configuring a cam ridge. The heat treatment method for the cam piece includes: a first step of using a jig formed into a shape having a cavity, the jig being inserted into the insertion hole such that the cavity is located between an inner circumferential surface of the nose portion of the cam piece and a central axis of the jig; and a second step of heating the cam piece from an outer circumferential surface side by high-frequency induction heating in a state in which the jig is inserted in the insertion hole of the cam piece.

Abstract: A valve train for an internal combustion engine that uses motors to open/close intake valves of cylinders. The motors drive the intake valves for each of a plurality of groups of cylinders that perform an explosion stroke at substantially equal crank angle intervals. Since the intake valves are driven for each of the plurality of groups of cylinders that perform an explosion stroke at substantially equal crank angle intervals, the explosion stroke is performed regularly even when an operation is conducted with only a particular group of cylinders. This makes it possible to inhibit driveability deterioration.

Abstract: No-load valve lift correction curves of opening and closing cams are set by offsetting no-load curve sections of basic valve lift curves of the cams in such directions as to increase a clearance between the curves, and they are connected with remaining sections of the curves to provide normal valve lift curves of the cams. Cam profiles of the cams are set on the basis of such normal valve lift curves. The cam profiles are set so that an ultimate speed difference between jumping and landing speeds of a follower on an ultimate valve speed curve determined from ultimate valve lift curves, having first and second shift sections where the follower shifts from the opening cam to the closing cam and from the closing cam to the opening cam, is smaller than a basic speed difference between jumping and landing speeds on a basic valve speed curve.

Abstract: A valve operating mechanism for an internal combustion engine for an automobile in which friction is decreased without an increase in the mass to be moved by the valve closing spring. The valve operating mechanism has a roller arranged on an actuation spindle. The roller cooperates with a bearing surface on a component of the mechanism that is connected to the valve, at least during valve opening, so that deviations of the valve lift curve from the desired valve lift curve are eliminated. Connection between the actuation spindle, through the roller, and the valve is maintained only during the valve-open cycle.

Abstract: A system for varying valve timing; i.e. the rotational angle of the crankshaft during which an intake or an exhaust valve of a cylinder of a reciprocating internal combustion engine is open which results in varying valve overlap, and for varying valve lift of such intake and exhaust valves. A desmodromic cam and cam follower convert rotation of a cam shaft to reciprocating rotation, or oscillation, of the cam follower. The reciprocating rotation of the cam follower is converted by the interaction of a secondary cylindrical cam, a cylindrical control ring, and a reciprocating member to linear motion of the reciprocating member which reciprocating member is operatively connected to a poppet valve. Timing and lift of the reciprocating member and valve are variable over predetermined limits as a function of engine rpm and load by rotation of the cylindrical control ring. Each valve train positively closes as well as opens its associated valve.
