Abstract: A vehicle system includes a vehicle engine, a plurality of intake and exhaust valves coupled to the vehicle engine configured to adjust performance of the vehicle engine, and a camshaft coupled to the plurality of intake and exhaust valves and configured to control timing of the intake and exhaust valves. The vehicle system also includes a camshaft phaser configured to adjust the position of an engine's camshaft. Moreover, the vehicle system includes a vehicle processor. The vehicle processor is configured to store data including vehicle data, and apply increased oil pressure to the camshaft phaser based on vehicle data such that oil pressure is increased at a predetermined vehicle data range of camshaft phaser instability to prevent future camshaft position instability.

Abstract: A pump includes a first gear plate and a first pair of counter rotating gears positioned on a first side of the gear plate. The pair of counter rotating gears draws fluid from an inlet and transfers the fluid into an outlet of a common manifold. The gear plate has a cutout to increase the flow of fluid into the common manifold.

Abstract: A method for exhaust braking includes monitoring, by a controller of a vehicle, an engine speed of an internal combustion engine; comparing, by the controller, the engine speed with the a predetermined braking speed threshold to determine whether the engine speed is greater than the a predetermined braking speed threshold; and, in response to determining that the engine speed is greater than the a predetermined braking speed threshold, switching the vehicle to an exhaust braking mode.

Abstract: An internal combustion engine has a variable intake manifold with one or more intake manifold tuning valves. Controlling the intake manifold tuning valve(s) involves determining an operating mode switching point of the intake manifold tuning valve(s). The operating mode switching point initiates opening and closing movements of the intake manifold tuning valve(s). The operating mode switching point is determined based in part or more upon temperature of intake air in the variable intake manifold.

Abstract: A temperature responsive valve includes a housing and a cylindrical structure disposed within the housing. The housing defines an inlet passageway and an outlet passageway wherein the cylinder body of the cylindrical structure is disposed between the inlet passageway and the outlet passageway. The cylindrical structure includes a first layer so that the cylindrical structure is configured to expand from a decreased diameter to an increased diameter when the first layer of the cylindrical structure is exposed to an increased pre-determined temperature range causing the cylindrical structure restricts the inlet passageway and the outlet passageway at such increased pre-determined temperature range.

Abstract: A gear pump can be equipped in an engine oil system. The gear pump has a housing, a first gear, and a second gear. The housing has an outlet passage for exiting oil, and has one or more outlet openings for exiting air. The first gear has a set of first teeth with multiple first roots and first tips. The second gear has a set of second teeth with multiple second roots and second tips. The outlet opening(s) is situated in the housing so that it can communicate with a first clearance, with a second clearance, or with both the first and second clearances. The first clearance is established at the confrontation of one of the first roots and one of the second tips. And the second clearance is established at the confrontation of one of the second roots and one of the first tips.

Abstract: A variable displacement pump is provided which better distributes stress across the rotor structure thereby reducing the risk of the rotor cracking and/or failing. The variable displacement pump includes a housing, a vane control ring, a rotor, a plurality of vanes, a slider ring, a biasing means, and a regulator valve. The housing defines an inlet port and a discharge port. The rotor may be rotationally driven by a drive shaft and coaxially aligned with the drive shaft. The rotor may define a plurality of primary ribs and a plurality of corresponding secondary ribs with an aperture defined between each primary rib and secondary rib. Each primary rib defines a primary rib thickness and each secondary rib defines a secondary rib thickness which is less than the primary rib thickness.

Abstract: A method and apparatus that detect a leak of vehicle fluid are provided. The method includes determining whether leak detection is active, capturing a first image of an area while parking a vehicle into the area if the leak detection is active, capturing a second image of the area while the vehicle is exiting from the area, comparing the first image and the second image to detect whether the leak is present, and outputting a notification indicating a leak is present if the comparing detects the leak.
