FIELD: mechanical engineering; heat internal combustion engines with power takeoff output shaft. ^ SUBSTANCE: according to proposed method, operation of separate individual functional compression, heat supply and expansion systems, interconnected both in series and in parallel, at carrying out thermodynamic processes of compression, heat supply and expansion are backed up, and mechanical work is divided to fulfill demands of heat engine and to overcome external load. In process of operation heat losses of engine are recovered by components of fuel mixture. In binary operating cycle of heat engine main and additional components of fuel mixture are used which are fed in process of compression by pumps and compressors along main lines of functional systems of engine through successive row of check valves into heat exchange sections where fuel mixture components are stored and prepared by heat exchange processes for fuel injection. Heat supply in gas distributing mechanism of combustion chamber is preceded and combined with completion of process of compression, and process of homogenization of fuel mixture is intensified. Process of compression is completed with formation of fuel charge in combustion chamber. In process of internal combustion heat supply in combustion chamber, ignition is backed up and combustion of fuel mixture is maintained. External combustion heat is supplied to combustion chamber with combination expansion nozzle, and water used in engine open cooling system is gradually heated, process of expansion of working media is combined with process of supply of external heat and heated water is converted in steam generator into super heated steam. Combination binary steam-gas flow is formed whose tangentially directed summary force pulse acts onto triple-shaft piston rotor where it is converted into binary cycle of working media large pressure in small sealed expansion volumes and small pressures of working media in large non-sealed expansion volumes are converted into mechanical work. Self-adjustable combination binary operating cycle of engine is formed in which both inner and outer supply of heat is effected. Stable operation of heat engine under automatic operating conditions self-adapting to changes of external load with self-adjusting redistribution of fuel mixture formation within the range of external performance characteristics of engine is provided. In "man-machine" control system, using manual control of engine operation, preset mixture formation is changed and heat release in combustion chamber at discretion of operator are provided. Proposed method can be used in heat internal combustion engine. ^ EFFECT: increased efficiency of heat internal combustion engine. ^ 3 cl, 8 dwg |
