A crankcase assembly for an engine comprising: a crankcase comprising a crank sump; the crank sump comprising primary and secondary sump volumes; one or more crankcase oil catchers, the crankcase oil catchers comprising surfaces to catch dispersed oil in the crankcase and direct the oil away from a crankcase casing wall and towards the crank sump, wherein the crankcase oil catchers are provided above a crankshaft and below a piston of the engine; and one or more guides to collect oil and guide the oil to the primary sump volume. At least a portion of the guide is movable between a first configuration in which the guide collects the captured oil that would otherwise have.

Oleophobic and/or oleophilic coatings to reduce heat loads on a gas turbine engine thermal management system are disclosed herein. An example method to reduce heat load in a gas turbine engine, the method including applying an oleophobic coating to an internal wall of a sump, the sump located in proximity to a heat generating element of the gas turbine engine, and applying an oleophilic coating to the heat generating element of the gas turbine engine.

A structural oil pan for a vehicle is formed from polymeric material, The structural oil pan includes a bracket portion configured for mounting to the vehicle, and a pan portion integrated with the bracket portion and defining an oil reservoir. The structural oil pan also includes a structural section defining a cavity within at least one of the bracket portion and the pan portion for reducing vibration.

The invention relates to a turbojet engine oil tank (30). The tank (30) comprises a main chamber and an envelope (34) delimiting the main chamber, and a fixing portion (44) for example with fixing flanges (46) and a branch (48). The envelope (34) features in particular an envelope part (34) relative to which the fixing portion (44) projects. The envelope part (34) and the fixing portion (44) are produced by layered additive fabrication so as to be in one piece. The invention also relates to a method of fabricating an oil tank (30).

[OBJECT] To provide a resin-made oil pan without breakage even when the oil pan strikes against an obstruction. [MEANS TO SOLVE] A bottom wall 2 of an oil pan 1 made of resin material has a front side wall section 5 that is located at a vehicle front side and a rear side wall section 6 that is located at a vehicle rear side with respect to the front side wall section 5 and continues to the front side wall section 5 at a predetermined angle. The front side wall section 5 is set so as to have an inclination so that as a position on the front side wall section 5 gets closer to the vehicle rear side, the position on the front side wall section 5 is located in a lower position in a vehicle up-and-down direction in a state in which the oil pan 1 is secured to a cylinder block mounted on a vehicle. As an external force absorption means, a plurality of lateral ribs 7, each of which has an almost rectangular shape in cross section and extends along a vehicle width direction, are formed on an outer wall surface 5a of the front side wall section 5.

An oil pan assembly includes a first portion formed of a first plastic, and a second portion formed of a second plastic that differs from the first plastic. The first portion is securely coupled to the second portion. The first plastic may be one of a thermoset or a thermoplastic. The second plastic may be the other of the thermoset or the thermoplastic.

A crankcase oil catcher configured for placement above a crankshaft and below a piston is described. In one particular example, the crankcase oil catcher has a contour that catches dispersed oil within the crankcase while directing the oil away from a casing wall and towards a crank sump along the contoured surface of the crankcase oil catcher. Inclusion of an aperture within the surface allows for passage of a connecting rod of the crankshaft while providing for a protruding lip around the perimeter of the aperture that prevents oil on the top surface from falling through the aperture.

An oil management system to reduce and remove the amount of soot, rust or other contaminating particles in oil used in an engine, the oil management system comprising an oil filter assembly including a filter element and an additive cartridge, the additive cartridge configured to provide a means for continuously dispersing a small quantity of additive into the oil; an oxidation prevention means to prevent or diminish oxidation of metal in the oil management system; and an oil condition monitoring sensor to measure various aspects of the oil in the oil management system.

A component and method for forming the component utilizing ultra-high strength steel is provided. The method includes the steps of providing a blank of ultra-high strength steel and forming the blank into an unfinished component. Next, heating the unfinished component and moving an inner tooling member and an outer tooling member relative to one another to sandwich the heated component therebetween. Further, moving a punch member from a withdrawn, unactuated position to an extended, actuated position to contact the component while sandwiched between the inner and outer tooling members to form a feature including at least one of a thickened region having an increased thickness relative to an adjacent region, a recessed annular groove, a recessed pocket, a through hole, a flange, a through hole having a tab extending outwardly therefrom, or spline teeth. Then, quenching the feature.

A joint assembly includes a first container portion, a second container portion, a band strip, and a fastener. The first container portion has a first flange including a first sealing surface and a first outer surface. The second container portion has a second flange including a second sealing surface and a second outer surface. The second sealing surface is configured to cooperate with the first sealing surface to form together a sealed connection. The fastener is configured to attach the band strip to one of the first and second container portions. An inner surface of the band strip is configured to engage at least one of the first and second outer surfaces such that the sealing surfaces of the first and second flanges are fixed with respect to one another when the band strip is attached to at least one of the first and second container portions.
