FIELD: engine building.
SUBSTANCE: invention relates to engine building, specifically to two-stroke internal combustion engines. Two-stroke engine with slot blowing comprises cylinder (1) accommodating piston to divide cylinder (1) chamber into working chamber (12) and sub-piston chamber (13). Piston has a trunk and a head connected to it. In cylinder (1) there are purging (5) and at least one outlet (6) openings, overlapped by the edge of the piston head, besides, there is at least one inlet opening (7) overlapped by the trunk edge and intended for the fresh charge inlet into the sub-piston cavity. Inlet opening (7) is located in the same longitudinal plane passing through geometric longitudinal axis of cylinder (1), in which outlet opening (6) is located. Inlet opening (7) is located on the same side of cylinder (1) as outlet opening (6). Piston is equipped with a means of sealing part of the surface of cylinder (1), on which outlet (6) and inlet (7) openings are located.
EFFECT: reduced heat intensity of the engine.
