FIELD: mechanical engineering; internal combustion engine with delivery of fuel through nozzle and carburetor engine. SUBSTANCE: compressed gas and air is delivered into engine cylinders according to firing order from starting bottle thus providing starting of engine. After first flashes in cylinders gas and air delivery is cut off using engine cylinder operating as compressor and then as engine or only as engine. Compressed gas with air is delivered through spark plugs provided with starting valves. Bottles are charged with mixture of air and gas generated in engine through charging spark plug furnished with return-starting, bypass and air-gas takeoff valves. EFFECT: improved reliability of starting, possibility of getting compressed air during engine operation without use of special compressor. 32 cl, 7 dwg
