Abstract

The invention discloses an entropy circulating engine which comprises a gas compressing mechanism, a gas working mechanism and a communication channel. The gas compressing mechanism is communicated with the gas working mechanism through the communication channel so as to form a working medium closed loop circuit. An internal combustion combustor is arranged inside the working medium closed loop circuit. A working medium guiding outlet is formed in the working medium closed loop circuit. At least one of the gas compressing mechanism and the gas working mechanism is arranged to be an impeller type, roots type or a screw type mechanism. The entropy circulating engine solves the problems that working medium temperature and pressure of an existing heat engine are difficult to heat to a deserved degree, so that efficiency of the heat engine is affected, and has the advantages of being high in efficiency and energy-saving.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to an entropy cycle engine. Background technique [0002] In recent years, the problems of high energy consumption and high pollution emissions of traditional internal combustion engines have become increasingly prominent. Therefore, heat engines have received extensive attention. However, heat engines heat the working fluid by means of external combustion heating. A working fluid with a higher temperature is obtained, therefore, causing a large amount of chemical loss. Not only that, due to the limited external combustion heating rate, high material requirements, and poor load response, the single-unit power and overall power density of the heat generator are severely restricted, and the use of the heat generator is severely limited in the end. Therefore, a new type of engine needs to be invented. Contents of the invention [0003] The invention provides an entropy cyc...
