About C71 SP

EX CO The invention of otHtJcurcH to a 1UH machine building, namely engine building and, in particular, to methods of operating an internal combustion engine with gas turbine blowing, with heat recovery and with a lower heat sink. Methods are known for operating an internal combustion engine by injecting fuel into a cylinder, burning it in a cylinder, performing work cycles, passing exhaust gases from a cylinder to a turbine of a turbocompressor, cooling exhaust gases after a turbine in a heat exchanger, compressing air in a supercharger, and separating the flow of air. after the compressor to the working and to the blower flows, feeding the latter into the cylinder, and the working flow to the heat exchanger, heating the working flow in it and feeding it into the piston-cylinder cavity for perfecting extra work i. However, not enough heat is recovered from the combustion of the fuel, and a considerable part of it is accumulated on the heating of the cylinder components and is lost in cooling systems. The process of s1x1rani fuel in the engine of such engines occurs at constant temperatures, which leads to a decrease in the efficiency and efficiency of the engine. In addition, in the case of such methods of operation in engines with a low heat sink (in adi & bat engines), in which there may be a high temperature of exhaust gases before the turbine, the reliability of the latter and of the engine as a whole are reduced. The aim of the invention is to increase efficiency by increasing the degree of heat utilization. . To achieve the goal, according to the method of operation of the internal combustion engine by injecting fuel into the cylinder, C1x wounds it in the cylinder, performing working cycles, supplying exhaust gases from the cylinder to the turbine, turbo-compressor, cooling the outflow gases after the turbine; compressing the air in the supercharger compressor, dividing the air flow after the compressor into the working and supercharging flows, feeding the latter into the cylinder, and the working flow into the heat exchanger, heating the working flow in it and feeding it into the piston chamber of the cylinder to do additional work, The working air flow is additionally heated with the help of the heat of the used gases, and the charge air flow is heated with the heat of the cylinder components. The drawing shows the scheme of the engine, which can be implemented in the proposed “1st method. The engine for carrying out the method comprises a composite piston 1, a cylinder 2, an exhaust manifold 3, an exhaust gas heat exchanger 4, a turbocharger turbine 5, an exhaust gas heat exchanger 6 and a supercharger 7. CYLINDER 2 contains a piston cavity 8 and an over piston cavity 9 in which a nozzle (not shown) is installed for fuel injection. The engine also contains an additional sleeve 10 connected (down to the center 2, in which the slider 11 is installed, which is part of the composite piston 1. In the piston cavity 8, the inlet 12 and the outlet 13 are filled. The engine is injected into cylinder 9 above piston cavity 2. Compressed fresh air, combustion of fuel, performance of working cycles, flow of exhaust gases from cylinder 2 to exhaust manifold 3 and to turbine 5 of turbocharger, cooling of exhaust gases after turbine 5 to warm The air pressure gauge 6 and compressed air in the compressor supercharger 7. Compressed air is separated after compressor 7 into working and charge streams, the latter is fed into the cylinder, and the working flow is transferred to the heat exchanger 6. The working flow is heated in the latter and fed through the inlet 12 into the piston cavity 8 of the cylinder 2 to perform additional work, and then through the outlet 13 is released into the atmosphere. To improve the efficiency of the engine, the working air flow is additionally heated in the heat exchanger 4 with the help of heat tavshih gases and the charge air flow - using the heat of the cylinder parts. For this, the charge air can be directed to a special casing (not shown) located around cylinder 2. The additional sleeve 1O and the slider 11 are designed to improve the reliability and efficiency of the engine and thereby reduce the lubricant flow rate. oils.

This embodiment solves some of the problems of lubricating adiabatic engines.
