FIELD: two-stroke internal combustion engines.
SUBSTANCE: cylinder-piston group of an internal combustion engine comprises a cylinder (1) with a groove (2) in its lower part, a block head (7) with an exhaust valve (8), a piston (12) rigidly connected to the rod (13), and a lower removable cover (9). One or more valves (16) are placed coaxially in the piston (12), rigidly connected to spring-loaded pushers (17). The spring-loaded pushers (17) have grooves aligned with the grooves of the rod (13) when pushers (17) and spring-loaded dampers (10) come into contact with the piston (12) in the lower position. The spring-loaded damper (10) is installed in the recess of the removable cover (9) or in the lug of the removable cover (9).
EFFECT: increasing the volume of air when moving it from the lower chamber to the upper chamber.
