Abstract: A sealing interface configured to prevent galvanic corrosion of a container having parts made of dissimilar materials includes a first part, a second part, and a sealant. The first part has a first sealing surface and a first exterior surface substantially perpendicular to the first sealing surface. The second part has a second sealing surface and a second exterior surface substantially perpendicular to the second sealing surface. One of the parts includes an external sealing chamfer on the respective sealing surface extending to the respective exterior surface. The sealant at least fills a space formed between the external sealing chamfer and the sealing surface of the other of the parts when the parts are connected, forming a barrier between the parts such that the exterior surfaces of the parts are not in contact and are separated by the sealant. The exterior surfaces may be flush when the parts are connected.

Abstract: A first target module determines a first target output pressure of an engine oil pump based on a speed of the engine oil pump and an oil temperature. A second target module, based on a runtime period of an engine, sets a second target output pressure of the engine oil pump to one of greater than and equal to the first target output pressure. A third target module, based on an engine load, sets a third target output pressure of the engine oil pump to one of greater than and equal to the first target output pressure. A selection module selects one of the second and third target output pressures, sets a selected target output pressure based on the selected one of the second and third target output pressures, and controls displacement of the engine oil pump based on the selected target output pressure.
