ABSTRACT:
Several embodiments of cooling arrangements for the pistons of an internal combustion engine operating on a two-cycle, crankcase compression principle. The cooling arrangement comprises a passage that is formed in the piston and which communicates the ports of the engine with each other when the piston is in confronting relationship with them so as to effect a cooling air flow across the piston through the communicating passage.
