A sealing portion deformation reducing type engine oil pan having a main compartment portion for storage of engine oil, may include a pan bottom portion configured to surround a bottom of the main compartment portion; a pan side portion configured to surround a side of the main compartment portion; and a flange portion configured to be formed at an upper portion of the pan side portion and mounted with a sealing gasket, wherein a reinforcing rib is disposed at a lower portion of the flange portion while being formed at an opening of the fan side portion.

The oil pan assembly includes an oil pan and a slideable cover. The oil pan includes a base and a sidewall which surrounds the base wherein the base and the sidewall are configured to retain a pool of oil. The oil pan further includes a peripheral flange operatively configured to be coupled to an engine block. The slideable cover is affixed to the oil pan and is configured to maintain the pool of oil proximate to the base of the oil pan.

An oil pan for trapping oil of an engine comprising: a curved portion connecting a flat portion and a side wall portion and including a rib-free region where a first reinforcing rib provided on the flat portion and a second reinforcing rib provided on the side wall portion are not connected to each other.

A method of forming a structural oil pan via lost core molding is disclosed. The structural oil pan comprises a bracket portion configured for mounting to the vehicle, a pan portion integrated with the bracket portion and defining an oil reservoir, and a structural section formed via lost core molding and defining a cavity. The method comprises the step of lost core molding by forming a metal core, molding the bracket portion and/or the pan portion about the metal core, and removing the metal core to form the structural section in at least one of the bracket portion and the pan portion. The method also includes co-molding the bracket portion and the pan portion together to form the structural oil pan.

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.

An article manufactured from a polymeric material filled with fibers has an exterior surface having an impact portion with an arcuate configuration to impart impact resistance to the article. The article also includes a plurality of ribs orientated and configured in a unique manner to also impart impact resistance to the article. The ribs extend from the exterior surface of the article. A fillet having a fillet radius interconnects the ribs and the exterior surface. The fibers of the polymeric material are aligned within the article parallel to a flow of the polymeric material when injected into a mold during a molding process. The ribs are oriented in a pattern relative to the fibers to maximize the impact resistance of the article.

A non-metallic lubricant pan for a vehicle that includes a body and a structural reinforcement member that is positioned within and secured to the body. The structural reinforcement member includes a drainage column that is generally aligned with a drain hole in the body and ribs that extend between the body and the drainage column such that the drainage column interconnects the ribs.
