FIELD: engines and pumps.
SUBSTANCE: in an engine containing at least two cylinders, the air is compressed in a compressor cylinder, it is transferred through a heat exchanger where heat is regenerated from the combustion products, into the working cylinder, in which the fuel is injected, its combustion with carrying out of expansion work. The presence of a system for monitoring and maintaining the pressure in the air circuit of the heat exchanger is new for carrying out the thermodynamic cycle and ensuring the engine's operability. The system for maintaining the pressure in the air circuit of the heat exchanger includes an occasional pumping compressor, a compressed air receiver, and system monitoring and control equipment.
EFFECT: increase in the efficiency of the internal combustion engine.
