The invention relates to an engine oil system (1, 1, 101) for supplying oil to oil using components (3) in a vehicle (800). The engine oil system comprises an oil pan (10) for holding oil received from the oil using components, an oil pump (20) fluidly connected to the oil pan for pumping oil from the oil pan to the oil using components, and an oil filter (30, 30 130) configured for cleaning the oil. The oil filter has a filter inlet (32, 32, 132) for receiving oil to be cleaned, and a filter outlet (34, 34 134) for discharging oil from the oil filter. The oil filter is arranged in the oil pan such that, in use, the filter outlet discharges oil into the oil pan.

A contamination removing device for removing a contamination from oil for lubricating a rolling bearing supporting a rotary shaft of a turbocharger includes a body portion including an oil channel for the oil to flow, and a contamination removing element for removing the contamination from the oil flowing through the oil channel, the contamination removing element being provided in the oil channel. The body portion is configured to be detachable from the housing so that the oil channel and an oil supply channel for the oil to flow communicate with each other, the oil supply channel being formed in a housing of the turbocharger.

An engine is provided which includes an oil gallery, a base attaching seat in an engine frame wall, and a base for component mounting attached to the base attaching seat. An oil cooler and an oil filter are mounted on the base for component mounting, and the base attaching seat is provided with an oil inlet communicating with an upstream-side passage of the oil gallery, and an oil outlet communicating with a downstream-side passage of the oil gallery. Attaching the base for component mounting to the base attaching seat allows engine oil flowing into the oil inlet of the base attaching seat from the upstream-side passage of the oil gallery to pass the base for component mounting, the oil cooler, and the oil filter, and flow out of the oil outlet of the base attaching seat to the downstream-side passage of the oil gallery.

An oil separator unit including an upstream member having an opening through which the blowby gas passes, a downstream member having a hit portion hit by the blowby gas, and a porous member trapping the oil mist contained in the blowby gas that has passed through the through hole. The upstream member includes an upstream surface facing a first surface of the porous member, and a spacer projected from the upstream surface so as to generate a gap between the first surface and the upstream surface to support the first surface. The spacer includes a support portion supporting a side surface between the first surface and the second surface of the porous member at an end of the spacer.

A cover for an oil filter housing is disclosed comprising an elongated body defining an upper end portion and an lower end portion, and having a central axis extending therethrough, which delineates an axial length of the body, wherein an axial bore extends through the body of the cover from the lower end portion thereof to an interior end wall in the upper end portion thereof for accommodating an axial portion of an oil filter located within the housing, the axial bore of the body having an axial length that is about 90% to about 94% of the axial length of the body.

The present invention relates to a method for converting a full flow oil and/or fuel filter system into a bypass filter system comprising the use of a retro-fittable bypass filter configured to directly replace the pre-existing full flow filter, without the need for additional hoses or mounts etc. as in existing methods. Also described is a filter device for converting a full flow oil and/or fuel filter system into a bypass filter system comprising: an inlet for allowing fluid into the filter; a plurality of screens for filtering particles from the fluid; a cellulose element for filtering moisture from the fluid; an outlet for allowing fluid out of the filter; and a bypass for fluid to bypass the cellulose element and at least one screen and exit the filter, wherein the bypass filter is configured to directly replace the pre-existing full flow filter.

An oil filter assembly for an engine of an outboard motor includes a base having a high-pressure inlet port, a filter-mounting interface for receiving a filter, and a drain-back port for receiving a drain-back insert of the filter. The base includes an engine-mounting interface for mounting the base to the engine, which includes a high-pressure outlet port and a low-pressure outlet port providing oil to the engine. The base provides fluid communication between the high-pressure inlet port and an inlet side of the filter and between an outlet side of the filter and the high-pressure outlet port when the filter is installed and the drain-back insert is within the drain-back port. The base provides fluid communication between the drain-back port and the low-pressure outlet port when the drain-back insert is not within the drain-back port. A clean oil fill passageway is in fluid communication with the low-pressure outlet port.

An oil mist separator including a case having an inlet portion and an outlet portion of a blowby gas and forming a passage from the inlet portion to the outlet portion, and an oil separator unit disposed in the passage. The oil separator unit includes a first plate part having a narrowing portion reducing an area of the passage and a second plate part having a hit portion hit by the blowby gas that has passed through the narrowing portion. The narrowing portion is configured by a notch formed from a predetermined end surface of the first plate part, and an inner wall of the case includes a fitting portion in which an end portion having the predetermined end surface of the first plate part is fitted.

The disclosure concerns a liquid filter assembly. The filter assembly includes a filter and a drain pin coupled to a lower support plate of the filter. The Drain pin includes a body, a grip, a seal member, and a fixing block structured and arranged to secure the drain pin to the filter. According to an implementation, the lower support plate has a receiving groove, and the fixing block is coupled to the receiving groove for securing the drain pin to the filter.

A housing and valving assembly for providing pre-charged oil filters wherein the housing is capable of interfacing with a mount interface, wherein the housing is configured to retain a volume of contaminated oil upon removal, and wherein the valving assembly is configured to minimize oil leakage upon insertion and removal of the housing from the mount interface.
