Abstract

The invention makes it possible to increase the efficiency of an engine with an external heat supply. The engine contains a piston 1, which is installed in the cylinder 2 and divides its internal volume into an expansion cavity 3 and a compression cavity 4 connected through a heater 9, a regenerator 13 and a cooler 11. The latter are joined and form a single cylindrical block. Heat is applied by means of an evaporative-condensation device made in the form of a casing 5 with a nozzle 6 for entering the hot heat carrier of the toroidal chamber 7 and a nozzle 8 for releasing the heat transfer medium. The walls of the latter have a capillary-porous structure 14 impregnated with sodium. The use of an evaporative condensation device makes it possible to increase the efficiency of the engine. 2 Il.

The game is related to mechanical engineering, in particular, to dvgatelestroyeniyu, and can be used when creating engines with external heat input.

The purpose of the invention is to increase the efficiency of the engine.

FIG. 1 shows a diagram of the engine; on league. 2 - the same cross section.

The engine contains a piston 1 installed in the cylinder 2 and dividing the cylinder cavity into the expansion cavity 3 and the compression cavity 4, the condensation heat transfer device, made in the form of a heat-insulating Covering casing 5 with an inlet 6 that is hot. chambers 7 and a branch pipe 8 for the release of a heat transfer medium in which heaters are installed, made in the form of cylindrical chambers 9 connected by radial channels 10 with a cavity 3 of expansion. The engine also contains a cooler, made in the form of a cylindrical chamber 11, in a design similar to a cylindrical chamber 9 connected by radial channels 12 to a cavity 4 of compression, and a regenerator 13 installed between the heater 9 and cooler 11 to form a cylindrical block. The drains of the inlet 6 of the hot coolant, the toroidal chamber 7 and the inlet 8 of the heat transfer fluid have a capillary-porous structure 14 impregnated with a coolant, for example, sodium.

The engine works as follows.

Hot coolant, such as flue gases, from a heat source through pipe 6 enters chamber 7 and, after passing through it, exits through outlet pipe 8. The passage through pipe 6, chamber 7 and pipe 8, hot coolant heats the walls of the structure, which causes evaporation sodium from capillary-porous C1-arm 14, the vapors of which fill the space enclosed between iijijuwji-2 and the enclosing heat insulating casing 3. The vapor-like sodium condenses on the outer and inner walls of the heater produced in the form of chi. skyscrapers 9,
