Abstract:
1. A mixture-lubricated internal combustion engine comprising: a cylinder having a cylinder wall; a piston movably mounted in said cylinder; said cylinder and said piston conjointly delimiting a combustion chamber; a crankcase connected to said cylinder; said crankcase defining a crankcase interior space and having a mixture inlet into said crankcase interior space through which an air/fuel mixture flows into said crankcase; a crankshaft having an outer periphery and being rotatably mounted in said interior space of said crankcase; a connecting rod connecting said piston to said crankshaft to permit said piston to drive said crankshaft in a rotational direction causing said air/fuel mixture to flow in the region of said crankshaft; at least one flow conducting element fixedly mounted in said interior space of said crankcase at a predetermined location therein; and, said flow conducting element projecting into said interior space and being directed opposite to said rotational direction of said crankshaft so as to branch off a component flow of said air/fuel mixture flowing in the region of said crankshaft and diverting said component flow to said piston thereby cooling said piston during operation of said engine.
