Embodiment 1

[0056] Such as figure 1 The shown single-cylinder three-type gate entropy cycle engine includes a cylinder-piston mechanism 1, the cylinder of the cylinder-piston mechanism 1 is provided with an air inlet 11 and an exhaust port 12, and the air inlet 11 and the exhaust port The air port 12 is respectively provided with a corresponding intake valve 13 and an exhaust valve 14, and also includes a working medium channel 2, and a reciprocating flow port 15 is set on the cylinder of the cylinder-piston mechanism 1, and at the reciprocating flow port 15 A corresponding reciprocating flow control door 16 is established; one end of the working fluid channel 2 communicates with the reciprocating flow port 15, and the other end is sealed; a cooler 3 is arranged on the sealing end of the working medium channel 2; The cylinder of the cylinder-piston mechanism 1 is provided with an internal combustion chamber 21 .

[0057] The working process of the engine in this embodiment is that the cy...

Embodiment 2

[0059] Such as figure 2 The difference between the shown single-cylinder three-type gate entropy cycle engine and Embodiment 1 is that a heat recovery is provided on the working medium channel 2 between the cooler 3 and the cylinder of the cylinder-piston mechanism 1 device 4, and the cylinder-piston mechanism 1 is provided with an ignition device 7.

[0060] The specific working process of the single-cylinder three-type door entropy cycle engine in this embodiment is: first, the cylinder-piston mechanism 1 works in the working form of an internal combustion engine: open the intake valve 13 to enter the intake stroke, and close the intake valve 13 complete the air compression stroke and the explosion work stroke. After the explosion stroke ends, the reciprocating flow control door 16 is opened to enter the heat engine cycle: when the piston goes up, the working medium is filled into the working medium passage 2, and the temperature is lowered at the sealing end of the workin...

Embodiment 3

[0063] Such as image 3 The shown single-cylinder three-type gate entropy cycle engine, on the basis of Embodiment 2, further includes a turbine power mechanism 5 , the working medium inlet of the turbine power mechanism 5 communicates with the exhaust port 12 .

[0064] The exhaust gas discharged from the exhaust port 12 is used to drive the turbine power mechanism 5 to perform work.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a single-cylinder three-type gate entropy cycle engine. Background technique [0002] At present, a heat engine is a Stirling engine, which generally includes a hot cylinder and a cold cylinder, as well as a working medium passage between the two cylinders. The piston in the center outputs work to the outside. The function of the cold cylinder in the prior art is to cool the working medium and return the working medium to the hot cylinder, which results in the complicated structure and high cost of the current Stirling engine. Therefore need to invent a kind of heat engine with simple structure. Contents of the invention [0003] In order to solve the above problems, the technical scheme proposed by the present invention is as follows: [0004] Scheme 1: A single-cylinder three-type gate entropy cycle engine, including a cylinder-piston mechanism, the cylinder-piston ...
