  • Publication number: 20240077006
    Abstract: A lubrication system for an internal combustion engine includes a fluid flow control device at an outlet side of the pump that regulates pressure conditions at the outlet side of the pump upstream of the lubrication circuit in the engine. The fluid flow control device is located in a recirculation path, and opens in response to a fluid pressure at the outlet of the pump exceeding a first threshold to allow the fluid to pass from the outlet side of the pump back to an inlet side of the pump. The recirculation path includes a tuning device that maintains the fluid pressure at engine speeds above the first threshold. In response to engine speeds above a second threshold, the tuning device restricts fluid flow in the recirculation path so that the fluid pressure in the fluid flow path increases.

  • Patent number: 10737699
    Abstract: A system and method are disclosed for controlling shifting of a vehicle having an automated manual transmission. In the system and method, an amount of fuel being provided to a first grouping of cylinders is reduced, where the first grouping of cylinders are fewer than all of the available cylinders; the first grouping of cylinders are placed in an engine braking mode; a first gear of the vehicle transmission is disengaged; an amount of fuel being provided to a second grouping of cylinders which does not include the first grouping of cylinders is reduced; engine speed is reduced by braking; and a second gear of the transmission is engaged.
