ABSTRACT:
An integrated engine guard oil cooler is mounted to a motorcycle. The cooler is a hollow tube having an inlet, an outlet, a plurality of cross-sectional restrictions in its interior, and a plurality of radial cooling fins on its exterior. The tube has a shape such that, when the inlet and the outlet are mounted on opposite sides of the lower frame of a motorcycle, the tube extends outwardly from each side of the frame, then extends upwardly, and then extends inwardly to join and form an enclosed passageway. When the inlet and the outlet communicate with the oil reservoir of the engine, oil flows through the tube with successive pressure increases and pressure decreases as it passes the cross-sectional restrictions and heat from the oil is transferred to the ambient air through the radial cooling fins.
