Abstract: A pivoting piston machine includes a housing, a first piston and a second piston arranged in the housing, the first and second pistons being pivotable away from one another and toward one another about a pivot axis. The machine has a working chamber arranged between first and second piston. The working chamber increases and decreases in size in alternating fashion during pivoting of the first piston and of the second piston. The machine also has a inlet mouth for admission and discharge of the working medium. A closing element for closing and opening the inlet or the outlet has a valve disk interacting with a valve seat. Either the inlet mouth or the outlet mouth is arranged within the working chamber between the first end surface and the second end surface, and the valve seat and the valve disk are arranged at either the inlet mouth or the outlet mouth.

Abstract: A startup/shutdown control module selectively generates an engine startup command when an engine of the vehicle is off. A starter control module applies power to a starter motor when the engine startup command is generated. A valve control module, in response to the generation of the engine startup command: operates intake valves of cylinders of the engine in a low lift mode when an engine temperature is less than a predetermined temperature; and operates the intake valves of the cylinders of the engine in a high lift mode when the engine temperature is greater than the predetermined temperature.

Abstract: A unitary cam follower and valve preload spring for a desmodromic valve mechanism having opening and closing cams mounted in parallel on an overhead camshaft so as to facilitate positive bidirectional drive of a valve. The device comprises a generally tubular spring member of oblong transverse cross-section, a shaped extension spring, preferably a band or basket. The spring member is configured to be nonrotatably mounted on the camshaft with its longitudinal axis parallel to the camshaft axis and its major axis aligned with the valve stem axis, substantially surrounding the opening and closing cams circumferentially and engaging the valve stem and closing cam so as to pull the valve stem in response to an upward force applied to the upper portion of the spring member by the closing cam. The spring member is further configured to elongate along its major axis in response to tension applied thereto during assembly so as to preload the valve stem, and it has an effective spring rate which varies depending on conditions.
