CRANKCASE OIL CATCHER
First Claim
1. A crankcase oil catcher configured for placement above a crankshaft and below a piston of an engine, comprising:
- one or more contoured surfaces for catching dispersed oil in the crankcase and directing the dispersed oil along the one or more contoured surfaces of the crankcase oil catcher to a crank sump, anda first aperture for a connecting rod of the crankshaft to pass through.

Abstract
A crankcase oil catcher configured for placement above a crankshaft and below a piston is described. In one particular example, the crankcase oil catcher has a contour that catches dispersed oil within the crankcase while directing the oil away from a casing wall and towards a crank sump along the contoured surface of the crankcase oil catcher. Inclusion of an aperture within the surface allows for passage of a connecting rod of the crankshaft while providing for a protruding lip around the perimeter of the aperture that prevents oil on the top surface from falling through the aperture.

12. An engine, comprising:
-
one or more cylinders within a crankcase arranged above a crankshaft that extends through the crankcase, a piston positioned within each cylinder that is coupled to the crankshaft by a connecting rod, a crankcase oil catcher placed below each piston of the engine and above the crankshaft, the crankcase oil catcher configured to direct oil along surfaces of the crankcase oil catcher away from a crankcase casing wall and towards a crank sump, wherein the crankcase oil catcher includes a first aperture sized for passage of only the connecting rod, and the crankcase oil catcher is configured to maintain a spacing apart from the crankcase casing wall. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A crankcase oil catcher configured for placement above a crankshaft and below a piston, comprising:
-
a top surface having a contour that follows a contour of a crankcase wall while maintaining a substantially constant spacing therefrom, the top surface allowing dispersed oil in the engine crankcase to be caught and directed to a crank sump along the top surface of the crankcase oil catcher while preventing oil from contacting the crankcase casing wall, an aperture with a width smaller than a width of the piston associated with a connecting rod of the engine crankshaft, the aperture sized only for passage of the crankshaft, and a lip protruding in a direction of the piston that extends around a perimeter of the aperture for preventing oil on the top surface from falling through the aperture.
