A lubrication system for internal combustion engines, in particular for vehicles with a rideable saddle, said system comprising a crank chamber in which at least one connecting rod is accommodated, and a basin or pan for collecting a lubricating liquid, wherein said crank chamber and said collection basin or pan are put in mutual communication by means of a first opening obtained in said crank chamber, wherein the flow of said lubricating liquid through said first opening from said crank chamber into said basin is adjusted by means of a first adjusting element adapted to be switched to an open position so as to allow the discharge of said lubricating liquid from said crank chamber into said collection basin or pan at a predetermined switching gas pressure value inside said crank chamber.

A cooling system for an outboard motor of a marine vessel is provided. The cooling system includes an oil sump housing having an inner housing wall and an outer housing wall. The inner housing wall defines a transmission mounting cavity, and the inner housing wall and the outer housing wall defines an oil containment cavity that at least partially surrounds the transmission mounting cavity. The cooling system further includes a first sprayer nozzle and a second sprayer nozzle. Both the first sprayer nozzle and the second sprayer nozzle are coupled to the oil sump housing and configured to spray cooling fluid within the transmission mounting cavity onto an inner surface of the inner housing wall.

An engine assembly includes an oil pan including an oil pan body defining a cavity. The oil pan body includes a dividing wall separating the cavity into a first compartment and a second compartment. The dividing wall defines a compartment opening extending therethrough, and the compartment opening fluidly interconnects the first compartment and the second compartment. The engine assembly also includes an oil pump at least partially disposed inside the first compartment of the oil pan. The oil pump includes a pump pickup conduit in fluid communication with the first compartment. The engine assembly additionally includes a temperature sensor disposed inside the pump pickup conduit of the oil pump. The temperature sensor can measure the temperature of oil flowing into the oil pump. In other words, the temperature sensor can sense the temperature of the oil pumped in the engine.

The present invention relates to automotive products, as well as uses thereof, which can facilitate warming of engine oil in an energy efficient and, therefore, more environmentally friendly manner. More specifically, a fluid reservoir is disclosed that includes a double walled vessel that defines a fluid containing compartment and has a self-contained region that shares a wall with the fluid containing compartment. A composition in the self-contained region at least partially covers the shared wall surface, and one or more light sources are positioned in the self-contained region to induce a phase change in the composition. The composition includes a phase-change material (PCM) and a molecular switch material. This fluid reservoir can be used to heat oil in an engine or oil pan.

A housing for a drive system. The housing defines a motor cavity, an electronics cold plate, an oil cavity, and a coolant cavity. The coolant cavity defines a first coolant flow path configured to provide cooling to the motor cavity and the oil cavity. The coolant cavity defines a second flow path configured to provide cooling to the motor cavity and the cold plate. The housing defines a coolant inlet and a coolant outlet fluidically coupled to the first coolant flow path and the second coolant flow path, such that the first coolant flow path and the second coolant flow path are parallel fluid paths. In some applications the coolant paths can be connected in series. In some examples, the housing is configured to cause a counter-flow heat exchange between an oil flowing in the oil cavity and a coolant flowing in the first coolant flow path.

The invention relates to an oil sump (1) comprising a lower shell (2) intended for containing lubricating oil of an engine, in which a flow of oil, referred to as suction oil flow (I), is sucked up via a suction tube (44) to supply a lubricating circuit, and an oil flow, referred to as returning oil flow (II), falls into the oil sump (1). The oil sump (1) comprises an anti-emulsion plate (8) arranged located at the mouth of the suction tube (44) during a transitional period in which the temperature of the oil is lower than an optimal operating temperature.

A hydraulic control system includes a primary sump and an auxiliary sump. When the transmission fluid is warm, fluid remains in the auxiliary sump reducing the volume of oil in circulation throughout the transmission to reduce parasitic losses. An oil control valve is designed to block flow of oil from the auxiliary sump to the primary sump when the fluid is warm and to allow flow when the fluid is cold. The oil control valve also responds to transmission line pressure. At moderate temperatures, fluid is held in the auxiliary sump when the engine is running but drains back to the primary sump when the engine is off.

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.
