FIELD: engine building.
SUBSTANCE: method is proposed in a two-stroke engine containing at least one cylinder (1) with piston (2) performing a reciprocating movement, limited combustion space (5), at least one outlet window (7) and inlet window (9) located above outlet window (7). Both windows (7, 9) are opened in a position of a lower dead point of the piston. Drive (8) is made with the possibility of opening valve (17) connected to it for intake of air for combustion to the combustion space through inlet tube (6) and the inlet window. Control system (15) after the position of the lower dead point of the piston gives a command to the drive to open valve (17). Valve (17) is opened, when the piston reaches inlet window (9) along the way to a position of its upper dead point. A two-stroke engine is also disclosed.
EFFECT: reduction in harmful emissions with exhaust gas, and increase in the engine efficiency.
