Abstract: FIELD: mechanical engineering; two-stroke internal combustion engines with slot scavenging. SUBSTANCE: engine has crankcase 1, crank chamber 2 formed in crankcase, one-throw shaft 3, cylinder 4 accommodating piston 5 with pin 6 coupled with shaft 3 by connecting rod 7, and spools 8 installed on ends of shaft 3. Scavenging ports 9 made in cylinder communicate with crank chamber 2 through bypass channels. Intake-exhaust 11 ports of cylinder communicate with intake-exhaust channels 12 in which spools 8 are installed for periodically placing intake exhaust channels 12 in communication with intake and exhaust main line. At the beginning of exhaust stroke exhaust gases are directed from cylinder 4 through intake-exhaust ports 11, intake-exhaust channels 12 and spool 8 into exhaust main line. Then piston 5 opens, by its upper edge, scavenging ports 9, and fresh charge gets into cylinder 4 from crank chamber 2, and scavenging of space of cylinder 4 takes place. After cleaning of cylinder space from exhaust gases spools 8 turn and cut off communication of space of cylinder 4 with exhaust main line. Further rotation of spools 8 provides communication of space of cylinder 4 with intake main line through the same gas distribution members through which exhaust gases have been evacuated, namely, intake-exhaust ports 11, intake-exhaust channels 12 and spools 8. Thanks to it delivery of fresh charge into cylinder 4 is provided through all ports made in cylinder, and cylinder is filled without losses of charge, with required degrees of precompression. Fresh charge is delivered into crank chamber 2 through ports 11, channels 12 and spools 8 only after port 11 has been opened by lower edge of piston 6 moving from bottom dead center. EFFECT: provision of maximum specific parameters at high economy, without affecting service life of engine owing to exclusion of charge losses at scavenging, possibility of supercharging of cylinders and provision of effective internal cooling of most heated parts of engine. 22 cl, 18 dwg
