Abstract: An oil pan for an engine comprises a containment portion of unitary construction. The containment portion has a circumferential component defining a circumferential extent of the containment portion and comprising a pair of mutually opposing side walls. The containment portion also comprises a base wall extending inwardly from a first portion of the circumferential component and defining a lower extent of the containment portion. The oil pan also comprises an attachment portion comprising an attachment surface at a second portion of the circumferential component; a first plug portion on an interior of a first one of the pair of mutually opposing side walls at a first location; and a second plug portion on an interior of a second one of the pair of mutually opposing side walls at a second location. The first and second plug portions are configured to receive an oil syphon connector and the attachment portion has a rotational symmetry such that the attachment surface is connectable to an engine block in a first orientation and in a second orientation. The first and second plug portions are located such that an oil tube having a fixed location relative to the engine block aligns adjacent the first plug portion on attachment of the attachment portion to the engine block in the first orientation and aligns adjacent the second plug portion on attachment of the attachment portion to the engine block in the second orientation.

Abstract: In one aspect, a system for coupling a fuel rail of a common rail fuel system to an internal combustion engine may include an engine wall having a plurality of openings. The fuel rail may have a main pipe portion located outside the engine wall, and a plurality of outlet pipes monolithically formed with the main pipe portion, each of the plurality of outlet pipes extending into a corresponding one of the plurality of openings of the engine wall. The system may further include a seal located in sealing engagement with each of the plurality of openings and a corresponding outlet pipe.
