A temperature regulating valve and a thermal management system provided with the temperature regulating valve are provided. The temperature regulating valve includes a filling state and a first working state, and a thermodynamic element is impelled to not abut against a first valve seat by means of providing a hot melt in an end cover of the temperature regulating valve. When a first valve port is in an open state, at said time the temperature regulating valve is installed in the thermal management system, and since the first valve port is in the open state, lubricating oil may then flow into a heat exchange device by means of a first interface channel, the first valve port, and a second interface channel during a process of filling the lubricating oil.

An oil circulation system of an internal combustion engine comprises a first oil pan and second oil pan, first oil supplied parts supplied with oil stored in the first oil pan, second oil supplied parts supplied with oil stored in the second oil pan, and a heating part. The heating part has oil paths through which oil flows and heats the oil flowing through the oil paths. The oil circulation system comprises a first circulation path circulating oil through the first oil pan, heating part, and first oil supplied parts, and a second circulation path circulating oil between the second oil pan and the second oil supplied parts.

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.

Methods and systems are provided for controlling a temperature of an oil used for lubricating an engine of a vehicle. In one example, a method comprises controlling an oil pump to pump oil at a first pressure, a second pressure or a third pressure in order to bias an oil cooler bypass valve to a first position, a second position or a third position, respectively, as a function of engine operating conditions. In this way, oil may be selectively routed through or around the oil cooler depending on engine operating conditions, which may serve to control oil temperature in line with the operating conditions and additionally improve fuel economy by reducing a load on the oil pump when operating conditions are such that the oil pump can be bypassed.

A system for collecting lube oil in an internal combustion engine with a rotating crankshaft assembly reduces lube oil aeration. The system includes a primary separation chamber arranged above an oil sump; an air interchange zone arranged above the primary separation chamber; an entrance aperture fluidly coupling the air interchange zone to the primary separation chamber; an exit aperture laterally spaced from the entrance aperture and fluidly coupling the primary separation chamber to the air interchange zone and for guiding air arising from the motion of the rotating crankshaft assembly from the primary separation chamber to the air interchange zone; and a main oil accumulation plate extending from the entrance aperture to the exit aperture and separating the primary separation chamber and the air interchange zone. The system further features a primary oil accumulation plate located above the exit aperture, extending towards the main oil accumulation plate at a first angle, and defining an airflow control aperture between the main oil accumulation plate and the primary oil accumulation plate through which fluids from the exit aperture are directed.

A marine engine comprises a powerhead having an engine block, a cylinder head and a crankcase containing a crankshaft. Operation of the marine engine causes rotation of the crankshaft. A crankcase cover encloses the crankshaft in the crankcase. A supercharger is on the crankcase cover, the supercharger being configured to provide charge air for combustion in the powerhead. A cooling passage conveys cooling fluid between the crankcase cover and the supercharger so that the cooling fluid cools both in the crankcase and in the supercharger.

An integrated flow control valve apparatus for controlling a flow rate of coolant in an engine cooling system for cooling an engine including a cylinder block and a cylinder head mounted above the cylinder block, includes a valve housing; a plurality of coolant ports formed at the valve housing and provided as inlets and outlets through which the coolant flows into and out of the valve housing; and valves configured for opening and closing the coolant ports, wherein the coolant ports include a first inlet port for introduction of the coolant from the cylinder block and a second inlet port for introduction of the coolant from the cylinder head into the valve housing; and the flow of the coolant at the first and second inlet ports is controlled by the valves configured to vary the flow of the coolant in the cylinder block and the cylinder head.

A vehicle includes an oil-cooling system arranged to circulate oil through an electric machine and an oil-to-coolant heat exchanger. A coolant system has conduit arranged to circulate coolant through an inverter, a heater core, and the heat exchanger. A climate control system is arranged to circulate an airstream through the heater core to heat a passenger cabin with waste heat from the electric machine and the inverter.

A method according to an exemplary aspect of the present disclosure includes, among other things, periodically adjusting powertrain operation of an electrified vehicle equipped with an internal combustion engine to progressively influence oil quality of oil of the internal combustion engine.

A filtration system includes a filter housing and a filter cartridge. The filter housing includes a base and a cover removably coupled to the base. The cover includes a retainer. The filter cartridge has a longitudinal axis and is movable between an installed position within the filter housing and an uninstalled position outside the filter housing. The filter cartridge includes a top endplate including at least one protrusion extending upwardly away from the top endplate. The protrusion includes a tab extending radially outward from the protrusion that is structured to interact with the retainer to removably couple the filter cartridge to the cover. The filter cartridge further includes a bottom endplate and a filter media extending axially between the top endplate and the bottom endplate.
