  • Oil-cooled engine assembly
    Patent number: 6659051
    Abstract: An oil-cooled engine assembly is provided for cooling lubricating oil, which has lubricated movable parts of an engine and subsequently recirculating cooled lubricating oil to the movable parts. The engine assembly includes a lubricating oil pump contained in the engine, and a hollow frame body which supports the engine. The hollow frame body has an oil passage through which lubricating oil flows. The lubricating oil pump is connected to the oil passage. Lubricating oil, which has lubricated the movable parts of the engine is air cooled with the frame body. Cooled lubricating oil is circulated again to the movable parts of the engine.
