Abstract

1. A piston-cylinder assembly for a two cycle internal combustion engine, having first recesses or grooves (9, 20, 31) longitudinally extending in the cylinder liner (3, 21, 36) and directly connecting the inner portion of motor crankcase with the motor combustion chamber when said piston (11) is in positions near its bottom dead center, characterized in that said first grooves cooperate with second grooves or recesses (17, 23, 32, 39) longitudinally extending in the piston liner (12, 24, 33, 38), in correspondence with the cylinder grooves, so as to conjointly form ducts or passages (19, 25, 34) which are adapted to ensure a sweeping of the motor combustion chamber, without involving any main gas feeding passage, said second grooves (17, 23, 32, 39) extending from the lower edge of said piston liner up to a position below the piston seats (14) for seating the piston rings.
