    Abstract: A detent assembly and a method of assembling the detent assembly are disclosed. The detent assembly includes a first shaft rotatable about a longitudinal axis and has an outer surface. The first shaft defines a cavity having an opening defined by the outer surface. The detent assembly further includes a camshaft defining an aperture along the longitudinal axis to present an inner wall of the camshaft that circumscribes the longitudinal axis. The inner wall defines a plurality of recesses spaced from each other. The detent assembly also includes a self-contained plunger unit that is secured to the first shaft in the cavity as a unit. A plunger of the self-contained plunger unit engages the inner wall as the camshaft is disposed over the self-contained plunger unit so that the plunger rests in one of the recesses of the camshaft to selectively secure together the first shaft and the camshaft.

    Abstract: The present invention relates to a variable valve timing system for an internal combustion engine which cyclically opens and closes a port providing fluid communication between a combustion chamber and a conduit leading thereto and which delays the closure of the port in response to a signal indicative of the power output required of the engine in order to vary the ratio of the mass of fluid inducted into the chamber to the mass of fluid expelled from said chamber during the period the port is open so that the mass of fluid retained in the chamber after closure of the port can be controlled without the use of a throttle valve.

    Abstract: A slide cam system includes a camshaft comprising a carrier shaft with slide cam elements that each comprise a slotted switching member having a switching groove. The slide cam elements are displaceable axially relative to the carrier shaft by an actuator pin. A displacement element is arranged parallel with a longitudinal axis of the carrier shaft, and the displacement element is axially displaceable in a direction of the longitudinal axis. The displacement element has a first coupling pin arranged in a region of the first slide cam element and a second coupling pin arranged in a region of the second slide cam element. The coupling pins cooperate with a slotted switching member of the associated slide cam element such that as a result of the displacement element a movement initiated by the actuator pin of the first slide cam element can be transmitted to the second slide cam element.

    Abstract: A variable valve-operating device for an internal combustion engine has a cam carrier with cam lobes formed therearound to act on an engine valve and with a speed increasing side lead groove and a speed decreasing side lead groove formed therearound to be engaged with a speed increasing side switching pin and a speed decreasing side switching pin, respectively, to axially shift the cam carrier, to selectively make one of the cam lobes to be operative. A speed increasing side entry lead groove portion of the speed increasing side lead groove is formed in a position axially overlapping a low speed steady position lead groove portion of the speed decreasing side lead groove. A speed decreasing side entry lead groove portion of the speed decreasing side entry lead groove is formed in a position axially overlapping a high speed steady position lead groove portion of the speed increasing side lead groove. The variable valve-operating device can thus be miniaturized by reducing the axial width of the cam carrier.

    Abstract: A method for operating an electromagnetic actuator (10) with an actuating pin (9) is proposed which comprises the following steps:—determining a pin actuation actual dead time (t11), during which the magnetic armature (15) is substantially immobile while a magnetic coil (12) is supplied with current, wherein the actual dead time ends with the current break-in at the magnetic coil, as a result of counter induction of the magnetic armature overcoming the magnetic force threshold;—determining, before a subsequent pin actuation, the starting time of the magnetic coil current supply, wherein the starting point of the current is advanced compared with that of the target movement start of the pin out of the actuator housing (13) and the determined actual dead time.

    Abstract: The present disclosure provides a shift gate for a sliding cam system with at least two shifting grooves for engaging at least one actuator pin. The shifting grooves extend in a circumferential direction of the shift gate. The two shifting grooves are at least partially separated from one another in an entry region of the actuator pin. In a transition region adjacent to the entry region, they converge on each other in such a manner that they merge into each other and form a common groove. The shifting grooves each comprise at least one groove flank, in particular a lead flank and/or a runoff flank, which narrows the shifting grooves at least in the transition region, in such a manner that a groove width of the shifting grooves in the transition region is smaller than a groove width of the shifting grooves in the entry region of the actuator pin.
