Abstract

FIELD OF THE INVENTION The invention relates to engine-building and allows an increase in engine efficiency. The engine contains a working cylinder 1 with a piston 2 forming a cavity 3 with a cover, a compression cylinder 4, a piston propeller 5. The latter is installed in cylinder 4 and divides its volume into hot and cold cavities 6 and 7. Cooler 9 and regenerator 10 are installed in line 8. A heater 12 and a regenerator 13 are installed in line 11, which is connected to line 8 between the compression cavity and the regenerator 13. Heat generated by compression of the working fluid in the working chamber occurs. When expanding, the working fluid passes into the working chamber only through the hot part of the regenerator, and when compressed, it passes into the compression chamber only through the cold part. 1 il.

The invention relates to mechanical engineering, in particular to engine-building, and can be used to create engines with an external supply tenlota.

The purpose of the invention is to increase the efficiency of the engine with external heat input.

The drawing shows a schematic diagram of the engine.

An engine with external heat supply contains a working cylinder 1, a hole 2 installed in the working cylinder and forming with it a cover a compaction floor 3, an pressure cylinder 4, a piston displacer 5 installed in the pressure cylinder and a partition of its third volume on a hot 6 and cold 7, a first line 8 with cooler 9 and a regenerator 10 installed therein, a second line 11 with heater 12 and a regenerator 13 installed in it, and a monlnum selection shaft 14 connected kinematically to pistons 2 and 5.

The engine works as follows.

During compression, the working fluid passes from the compression cavity 3 through line 8 to the cold 7 cavity of the cylinder 4 through the regenerator 10, to which the heat of compression of the working fluid is transferred, and cooler 9.

By the end of the compression, the piston propellant 5 begins to move to m / m. and the working fluid is distilled through cooler 8, regenerators 10 and 13, and heater 2 into the hot cavity 6 of cylinder 4 of the engine. The working fluid takes the heat of the regenerators 10 and 13 and the heater 12, its pressure rises.

After the piston reaches 2 in. M.t. the pacHiHren process begins. The working fluid flows from the hot cavity 6 into the compression cavity 3 through the heater 12 and the regenerator 13 through line I 1 and 8. The working volume of the engine increases, the pressure of the working fluid decreases. Towards the end of the expansion process, the piston propellant 5 moves in the opposite direction, moving the working fluid from the hot cavity 6 to the cold 7, through the heater 12, the regenerators 13 and 10 and the cooler 9 through the main lines 11 and 8. The temperature and pressure of the working fluid fall. after which the cycle is repeated.
