FIELD: mechanical engineering; manufacture of engines. SUBSTANCE: engine has housing with cylinder 1 which receives first piston 2 and second piston 3 which form together with cylinder 1 above-piston working chamber, compressor chamber 16 and buffer chamber 17, respectively. Rod 4 of first piston is connected with crankpins of two cranks 13 and 14 and rod 5 of second piston 3 is connected with main journals of cranks 13 and 14 which are mounted on eccentric 9 and 10 of bevel wheels 11 and 12 connected with sun bevel wheel 15 and with output shaft.
