FIELD: engines and pumps.
SUBSTANCE: invention relates to combined internal combustion engines (ICE). Present invention consists in that in outlet pipe of piston ICE is fitted with nozzle-injector operating in pulse mode, which sprays in high-temperature combustion products flow evaporating fluid, and turbine running on energy of steam-gas mixture. Evaporating liquid used can be liquefied carbon dioxide, air, alcohol, water, a mixture of water with an alcohol, etc. To provide operation of unit without large pulsations of outlet pipe is divided into multiple separate pipes of smaller cross-section located opposite working blades of turbine. To prevent propagation of steam-gas mixture pressure towards engine ahead of nozzles-injectors in discharge pipes are check valves, which are a rotary disc with holes for direct passing of exhaust gases.
EFFECT: reduced heat losses and improved ecological compatibility.
