Methods and systems are provided for an oil heater of a hybrid electric vehicle. The oil heater comprises a metal foam comprising a plurality of pores. The oil heater is activated during a regenerative braking event where an oil temperature is less than a predefined temperature.

A system includes a valve actuation system, a pre-lubrication pump coupled to a lubrication circuit and configured to provide oil to the valve actuation system, a catalyst for receiving and treating exhaust gasses, and a controller. The controller is configured to identify an engine start request and determine whether the catalyst temperature is below a first threshold value. In response to determining that the catalyst temperature is below the first threshold value, the controller actuates the pre-lubrication pump to direct lubricant to the valve actuation system, controls the valve actuation system to deactivate at least one cylinder of an engine, and, subsequent to deactivating the at least one cylinder of the engine, cranks the engine.

Systems and apparatuses include a generator set including an alternator, a transmission coupled to the alternator and structured to receive power from an engine, and an oil heating system including an oil pan structured to provide lubricating oil to the engine and including an oil outlet and an oil inlet, a plurality of immersion heaters positioned at least partially within the oil pan, a return line positioned within the oil pan, coupled to the oil inlet, and including a plurality of apertures for providing oil into the oil pan, each aperture aligned with a corresponding one of the plurality of immersion heaters, and a pump receiving oil from the oil outlet, and providing oil to the oil inlet.

A vehicle heating/cooling system has first and second fluid circulation loops for circulating engine coolant and automotive fluid. A first heat exchanger transfers heat from the coolant to air for the passenger compartment. A second heat exchanger transfers heat between the coolant and automotive fluid. A first valve has first and second inlets for receiving coolant from hot and cold coolant sources, and an outlet for discharging coolant to the second heat exchanger. A second valve has an inlet for receiving coolant from the first coolant source, and an outlet for discharging coolant to the first inlet of the first valve. The valve positions change with temperature of the coolant and the automotive fluid, providing preferential heating of the passenger compartment during cold start-up of the vehicle. The second heat exchanger and valves may be provided in a temperature control module.

A component for a motor vehicle, with at least one receiving space for structural elements of the drive component, with at least one first wall that delimits the receiving space at least partially, by way of which at least one collecting region for collecting a lubricant for lubricating the structural elements is delimited at least partially, and with at least one second wall, which is arranged on a side of the first wall that faces away from the collecting region, and which is spaced apart from the first wall at least in a partial region, so that, between the walls, an intermediate space that is delimited at least partially by the walls is formed. For setting a heat transfer coefficient between the walls, a liquid can be introduced into the intermediate space and discharged out of the intermediate space.

A control device for an internal combustion engine is provided which enables control of dilution of oil by fuel and water drops, i.e., control of the amount of so-called oil dilution. The control device for an internal combustion engine that is lubricated or cooled by oil includes: a variable displacement oil pump capable of varying the amount of discharge of the oil; an air-fuel ratio sensor for sensing an air-fuel ratio of the internal combustion engine; and an ECU for controlling the amount of discharge of the variable displacement oil pump. The ECU controls the amount of discharge of the variable displacement oil pump, based on the air-fuel ratio sensed by the air-fuel ratio sensor.

An exemplary fluid heating method includes, among other things, operating an engine of a vehicle to heat an engine fluid during a drive cycle if the vehicle is in a fluid maintenance mode, and heating the fluid prior to the drive cycle if the vehicle is in the fluid maintenance mode and the vehicle is electrically coupled to a grid power source. An exemplary fluid heating assembly includes, among other things, an engine of an electrified vehicle, and a fluid heater that is activated to heat a fluid of the engine in response to the electrified vehicle being in a fluid maintenance mode when electrically coupled to a grid power source.

A device for preventing dilution of engine oil includes an oil pan in which oil for lubrication of the engine is recovered with fuel. An exhaust purifier is provided on a rear end of the engine and purifying exhaust gas. A gas passage can guide flow of exhaust gas passing through the exhaust purifier to the oil pan. A gas valve can control flow rate of the exhaust gas flowing in the gas passage. A controller controls an opening ratio of the gas valve depending on a temperature of oil inside the oil pan to maintain the temperature of the oil equal to or higher than a temperature at which the fuel in the oil pan is vaporized.

Provided is an internal combustion engine, comprising at least one cooling device for cooling at least one operational liquid of the internal combustion engine during and/or after operation of the internal combustion engine. The at least one cooling device has at least one heat exchanger and lines for transporting the at least one operational liquid to and from the at least one heat exchanger. The heat exchanger exchanges heat with a cooling medium, which cooling medium has during the operation of the internal combustion engine a lower temperature than the at least one operational liquid of the internal combustion engine. Heat is exchanged by the heat exchanger between the at least one operational liquid and the cooling medium, which cooling medium has before and/or during a starting operation of the internal combustion engine a higher temperature than the at least one operational liquid of the internal combustion engine.
