  • Patent number: 10508616
    Abstract: An engine is provided with a cylinder block and a ladderframe having a portion of an oil conduit and a deflector. The engine has a metal-to-metal seal positioned between the ladderframe and block to circumferentially surround the oil conduit, and has a gasket seal positioned between the ladderframe and block to be outboard and spaced apart from the oil conduit. The deflector is positioned between the metal-to-metal seal and the gasket seal. An engine component is provided with a member having a deflector and forming an oil conduit. The deflector has an arcuate deflector surface following an outer wall of the oil conduit to redirect oil escaping the oil conduit. A ladderframe is configured to provide a deflection surface, with the deflection surface positioned to guide high pressure oil away from adjacent RTV seals.

  • Patent number: 10054042
    Abstract: An engine assembly is provided, the engine assembly comprising an engine cover configured to cover a portion of an engine housing. The engine cover comprises: a coupling region provided around a periphery of at least a portion of the engine cover, the coupling region configured to mate with a corresponding coupling region on the engine housing so as to form a seal between the engine cover and the engine housing, and an engine cover boss provided on a planar region of the engine cover and spaced apart from the coupling region, the engine cover boss comprising a contact surface configured to receive an adhesive to couple the engine cover to a corresponding contact surface of the engine housing.
