gas exchange entropy cycle engine

Abstract

The invention disclose a gas exchange entropy circulation engine which comprises a gas compression mechanism, a gas acting mechanism and a communicating passage. The gas compression mechanism is communicated with the gas acting mechanism through the communicating passage. A heat regenerator is disposed on the communicating passage. An oxidant inlet and a working medium outlet are formed in the communicating passage between the heat regenerator and the gas compression mechanism or in the gas compression mechanism. The oxidant inlet is communicated with an auxiliary gas compression mechanism. An oxidant control valve is disposed on the communicating passage between the oxidant inlet and the auxiliary gas compression mechanism. The working medium outlet is communicated with an auxiliary gas acting mechanism. A working medium discharge control valve is disposed on the communicating passage between the working medium outlet and the auxiliary gas acting mechanism. The gas exchange entropy circulation engine has the advantages that internal combustion heating is used to increase efficiency and power density, and accordingly energy can be saved effectively, and size, weight and manufacturing cost of the engine can be reduced greatly.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to an air exchange entropy cycle engine. Background technique [0002] In recent years, the problems of high energy consumption and high pollution emission of traditional 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. As we all know, it is difficult to obtain a higher temperature working fluid in the external combustion heating process, so 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. Moreover, in the working process of the heat engine, not only the working mechanism nee...

Problems solved by technology

As we all know, it is difficult to obtain a working fluid with a higher temperature in the external combustion heating process, thus causing a large amount of chemical loss

Not only that, due to the limited rate of external combustion heating, high requirements on materials, and poor load response, this severely restricts the single-unit power and overall power density of the heat generator, and ultimately severely limits the use of the heat generator

Moreover, in the working process of the heat engine, not only the working mechanism needs to be heated, but also the compression mechanism needs to be cooled to realize the temperature difference, so that the heat engine can perform external work, but this will cause the engine to waste a lot of energy that can be used
