Abstract: A variable displacement vane pump includes a housing, an expandable vane control ring, a rotor, a plurality of vanes, slider ring, and biasing means. The expandable vane control ring defines a gap. The plurality of vanes may be slidably disposed in the rotor. The slider ring is pivotally affixed to the housing via a pivot. The slider ring may form a plurality of pumping chambers with the expandable vane control ring, the rotor and the vanes. The distal end of each vane in the plurality of vanes is configured to abut and slide along an inner surface of the slider ring while the rotor rotates and the expandable vane control ring is configured to temporarily contract when intermittent friction is experienced between the inner surface and any vane in the plurality of vanes—so that the plurality of vanes continuously slide along an inner surface of the slider ring.

Abstract: A control methodology for a wireless oil level sensor includes mounting a wireless oil pressure sensor to the oil plug of an engine. The oil pressure sensor detects a pressure which is used to determine a volume or level of oil in the oil pan. The oil level sensor can include an accelerometer sensor that can be excited by the vibration caused by the starting of the engine to “wake up” the sensor. The sensor can take an initial pressure reading at start up and associate the pressure reading with an oil level that can then be transmitted to a vehicle control unit. The sensor can remain idle until the accelerometer sensor no longer detects engine vibrations. The sensor is activated to take pressure readings at predetermined time intervals and to transmit an associated oil level to the vehicle central processor unit until a predetermined time period has expired.

Abstract: A first target module determines a first target output pressure of an engine oil pump based on a speed of the engine oil pump and an oil temperature. A second target module, based on a runtime period of an engine, sets a second target output pressure of the engine oil pump to one of greater than and equal to the first target output pressure. A third target module, based on an engine load, sets a third target output pressure of the engine oil pump to one of greater than and equal to the first target output pressure. A selection module selects one of the second and third target output pressures, sets a selected target output pressure based on the selected one of the second and third target output pressures, and controls displacement of the engine oil pump based on the selected target output pressure.

Abstract: A hydraulic cam phaser includes at least one of an advance chamber and a retard chamber for receiving hydraulic fluid for advancing or retarding a rotational position of the camshaft. The hydraulic actuation system includes a hydraulic accumulator in selective communication with the at least one of the advance and retard chambers of the hydraulic cam phaser. A first system oil pump provides lubrication oil to the valvetrain system, and the hydraulic actuation system includes a second oil pump for supplying oil to the hydraulic accumulator. The second oil pump is controlled with a clutch device connecting the second oil pump to the engine drive system. The internal combustion engine includes a controller which controls actuation of the clutch device to actuate the clutch device during deceleration of the vehicle.

Abstract: A tensioner device, includes a housing defining a cylindrical bore. A plunger is disposed in the bore and has a non-cylindrical outer surface. A spring is engaged with the plunger for biasing the plunger in an outward direction and an oil passage is in communication with the cylindrical bore for delivering pressurized oil to the bore. The non-cylindrical outer surface provides hydraulic clearance areas between the plunger and the bore to provide improved damping without high damping force.
