FIELD: engines.
SUBSTANCE: invention relates to engine construction. Combined rotary piston internal combustion engine consists of piston internal combustion engine and arranged on its working shaft enclosed in a common chamber rotary engine and exhaust pump. Volume of rotary engine working chamber is greater than that of cylinder piston internal combustion engine so that, at end of working cycle of rotary engine gas pressure in working chamber of rotary engine is slightly below atmospheric pressure. In working chamber of rotary engine waste gases of internal combustion engine are removed. Exhaust pump removes waste gases from rotary engine, entering chamber common for rotary engine and exhaust pump, outside it.
EFFECT: technical result is design of combined engines of different power.
