Description

technical field [0001] The invention relates to the field of engines, in particular to a deep compression unit engine. Background technique [0002] The U.S. Patent Document No. 5050570 discloses an engine, which includes a cold cylinder and a hot cylinder. The gaseous working medium is compressed by the cold cylinder and enters the hot cylinder through a regenerator. After the radiator cools down, the engine is less efficient. The applicant's research found that the reason for the low efficiency of the engine is that the cold cylinder cannot provide high-pressure gas with high pressure. [0003] The cold cylinder of the engine in this document is set to be compressed by a one-stage piston compressor. If a high-pressure gas with a relatively large pressure is provided after being compressed by the one-stage piston compressor, the efficiency of the piston compressor will be very low, and it will take It's huge and expensive to make. [0004] The gas pressure provided by th...
