The rocker is operable to rotate about a fixed axis and the cam follower includes a set of lower rollers operable to follow one cam lobe and an upper roller operable to follow another cam lobe. A leaf spring can be used to couple the cam follower with the rocker. A cam shaft can have a nested configuration that includes an inner shaft, an intermediate tube, and an outer tube. Cam lobes can be fastened to the cam shaft by fastening through each of the inner shaft, intermediate tube, and outer tube. The cam lobes can be attached by at least two devices inserted from either side of the cam shaft and that are not inserted at least through the inner shaft.

Abstract: An internal-combustion engine with two intake valves for each cylinder is provided with a system for variable actuation of the intake valves, including a single solenoid valve for each cylinder that controls communication of a pressurized-fluid chamber of the system with an exhaust channel. The solenoid valve is a three-way, three-position solenoid valve, including an inlet permanently communicating with the pressurized-fluid chamber and with the hydraulic actuator of an intake valve, and two outlets communicating, respectively, with the actuator of the other intake valve and with the exhaust channel. The solenoid valve has a first position, in which the inlet communicates with both of the outlets, a second position, in which the inlet communicates only with the aforementioned outlet connected to the actuator of an intake valve and does not communicate, instead, with the outlet connected to the exhaust channel, and a third position, in which the inlet does not communicate with any of the two outlets.

Abstract: While an operating angle or a lift of an engine valve (211) is modified within a predetermined operating angle range or lift range, variation in an opening timing of the engine valve (211) is suppressed by displacing a rocker shaft (216b) relative to a drive shaft (213) such that an opening timing variation of the engine valve (211) accompanying angular variation in a straight line linking a center of the drive shaft (213) and a center of the rocker shaft (216b) and an opening timing variation of the engine valve (211) accompanying variation in a distance between the center of the drive shaft (213) and the center of the rocker shaft (216b) cancel each other out.

A gas exchange valve has the transmission arrangement act thereon. A valve-lift adjusting device comprises a rotatable adjusting element with an eccentric element having two base points and a peak contour, and at least one further eccentric element. The valve-lift adjusting device acts on the transmission arrangement so that different valve-lift positions are settable. The transmission arrangement is connected to the valve-lift adjusting device and to the camshaft. The at least one further eccentric element of the rotating adjusting element is arranged so that at least two peak contours are provided so that, depending on a rotational angle α of the rotating adjusting element, the eccentric element or the at least one further eccentric element engage with the transmission arrangement.

Abstract: A method is provided for diagnosing a multi-mode valve train device which selectively provides high lift and low lift to a combustion valve of an internal combustion engine having a camshaft phaser actuated by an electric motor. The method includes applying a variable electric current to the electric motor to achieve a desired camshaft phaser operational mode and commanding the multi-mode valve train device to a desired valve train device operational mode selected from a high lift mode and a low lift mode. The method also includes monitoring the variable electric current and calculating a first characteristic of the parameter. The method also includes comparing the calculated first characteristic against a predetermined value of the first characteristic measured when the multi-mode valve train device is known to be in the desired valve train device operational mode.
