Abstract: Embodiments for a cooling arrangement are provided. In one example, a cooling arrangement comprises a low-temperature circuit for charge-air cooling of a turbocharger of an internal combustion engine, an engine cooling circuit for cooling the internal combustion engine, and a charge-air cooler arranged in the low-temperature circuit and connected in a fluid-conducting manner on a coolant inlet side, via a first valve device, to the low-temperature circuit and to the engine cooling circuit, and on a coolant outlet side, via a second valve device, to the low-temperature circuit and to the engine cooling circuit. In this way, coolant from the engine may heat the charge-air cooler under certain conditions.

Abstract: A method for operation of a lubrication circuit in an internal combustion engine is provided herein. The method comprises during a first operating condition, operating an oil agitation device to increase the turbulence of oil in the lubrication circuit, the oil agitation device positioned downstream of an oil pump in a supply line in fluidic communication with a lubricant receiving component.

Abstract: An internal combustion engine is provided. The internal combustion engine includes an oil circuit and a pump in fluidic communication with a supply line and at least one lubricant receiving component and a liquid cooling system including a coolant circuit having an oil pressure actuated coolant valve and a coolant valve control line in fluidic communication with the pump and having a first configuration in which coolant may flow therethrough and a second configuration in which coolant is inhibited from flowing therethrough, the first and second configurations triggered in response to a change in oil pressure in the coolant valve control line.

Abstract: Embodiments for a lubrication system for an internal combustion engine are provided. In one example, a lubrication system for an internal combustion engine comprises a lubricant circuit, a radiator for cooling the lubricant, a heat accumulator arranged upstream of the engine for warming up the lubricant, the heat accumulator connected in parallel to the radiator, and a valve for switching over the lubricant circuit between the radiator and the heat accumulator. In this way, the oil may be rapidly heated during cold engine start conditions.

Abstract: A cooling system for an engine is provided. In one embodiment, an internal combustion engine comprises a cabin heat exchanger circuit including a connecting line opening on an inlet side into a cylinder block coolant jacket, a main coolant pump arranged in the cabin heat exchanger circuit, an auxiliary coolant pump arranged in the connecting line, and a check valve. In this way, additional cooling and/or heating may be provided to the engine and associated components by the auxiliary coolant pump.

Abstract: A method for operation of a high pressure exhaust-gas recirculation (EGR) system is provided. The method includes transferring heat from an exhaust flow through an EGR cooler to an engine coolant, the EGR cooler coupled to an EGR line fluidly coupled in parallel with a turbine and directing a controlled portion of the exhaust flow from the EGR cooler to an engine intake. The method further includes directing another controlled portion of the exhaust flow from the EGR cooler to the surrounding atmosphere.

Abstract: A cooling arrangement for an internal combustion engine is described, with a coolant balancing tank which is capable of being filled with coolant and the inlet side of which is connected via a first venting line to an internal combustion engine and/or via a second venting line to a cooler for cooling the coolant, and the outlet side of which is connected via a coolant return line to the inlet side of a pumping device for pumping the coolant through the internal combustion engine. The cooling arrangement has, furthermore, a flow control unit for variably limiting the coolant volume flow in the venting line.

Abstract: A system and method are provided for increasing heating of engine oil during a cold start. In one example, engine oil is returned directly to the oil pump inlet, thus bypassing the sump. In this way, a smaller volume of oil receives more heat and is used for lubricating engine components during a cold start, thus providing reduced friction earlier than otherwise possible.
