A double sump oil pan includes a separator made of plastic that partitions the interior of the oil pan into an inner sump and an outer sump, a plate, and an elastically deformable sealing member attached to the plate. The sealing member closely contacts the inner wall of the oil pan and seals the outer sump. The plate and the separator are fixed to each other.

An apparatus is described for heating oil for an internal-combustion engine. The apparatus includes a heat-exchanger arranged within an oil sump of the internal-combustion engine, which is flowed through or capable of being flowed through by a thermal medium for the purpose of emitting heat to oil in the oil sump. The apparatus further includes a heat-source in fluidic communication with the heat-exchanger, which is designed to heat the thermal medium outside the oil sump and outside the internal-combustion engine.

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.

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 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.

An oil pan may include a pan body forming a dual chamber including a primary chamber and a secondary chamber, and a mesh. The primary chamber and the secondary chamber each contains a different amount of oil, and the mesh allows a different amount of oil permeation discharged from the secondary chamber to the primary chamber based on temperature of the oil.

As a further improvement of the technique of minimizing or preventing excessive cooling of an oil separator, an effective blow-by gas heating apparatus which minimizes or solves the problems due to frozen blow-by gas in an engine externally equipped with an oil separator is provided. The blow-by gas heating apparatus includes: a heat emitting structure abutted onto an oil separator configured to trap and remove oil from blow-by gas. The heat emitting structure has a heat emitting case including inside a passage for engine cooling water. The heat emitting case includes a ceiling wall being in surface-contact from below with a bottom surface of the oil separator.

The oil circulation system of an internal combustion engine comprises: a high temperature side oil circulation path provided with a high temperature side oil pan, a high temperature side part supplied with oil, and a heating part, and circulating oil among these; a low temperature side oil circulation path provided with a low temperature side oil pan and a low temperature side part supplied with oil, and circulating oil between the low temperature side oil pan and the low temperature side part supplied with oil; an oil transport mechanism transporting oil between the low temperature side oil circulation path and the high temperature side oil circulation path; and a control device configured to control transport of oil by the oil transport mechanism while the internal combustion engine is operating.

Provided are oil reservoirs and engine oil circulation systems including an upper sump capable of receiving oil from an engine, a lower sump disposed vertically below the upper sump, a valve-controlled orifice (VCO) penetrating the upper sum bottom, an oil chimney capable of receiving oil and communicating oil to the lower sump, and an oil conduit capable of extracting oil from the lower sump. Methods for operating systems include maintaining the VCO in an open position for a draw down duration temporally proximate an engine cold start, subsequently circulating oil between the engine and the oil reservoir, actuating the VCO to a closed position subsequent to the draw down duration for a warmup duration, and actuating the VCO to an open position subsequent to the warmup duration. Methods can further include actuating the VCO to an open position during the warmup duration in response to an increased oil demand event.
