Engine with heat dynamic balance heat exchange system

Abstract

The invention discloses an engine with a heat dynamic balance heat exchange system. The engine comprises a machine shell, a crankshaft set, a piston assembly, an gas distribution assembly and an auxiliary cylinder body, wherein the crankshaft set is arranged at one end in the machine shell, the gas distribution assembly is arranged at the other end in the machine shell, the piston assembly is connected with the crankshaft set and slides along the inner wall of the machine shell, in the machine shell, the area between the piston assembly and the gas distribution assembly is a working cavity, the auxiliary cylinder body is arranged in the machine shell, the wall face of the auxiliary cylinder body exchanges heat with working gas in the working cavity, the machine shell is provided with a gasinlet and a gas outlet at the end of the gas distribution assembly, and the gas distribution assembly controls the gas inlet and the gas outlet to be opened and closed. According to the engine, the medium in the auxiliary cylinder body is separated from the working cavity, heat exchange can be conducted through the wall face, the compression expansion process of the working cavity is opposite tothat in the auxiliary cylinder body, the changing curve of the compression process is flat, and the compression ratio is larger; and when the working cavity expands to do work, heat in the auxiliary cylinder body is discharged, and heat of gas in the working cavity can obtain one more way.

Description

technical field [0001] The invention relates to the field of engines, in particular to an engine with a heat dynamic balance heat exchange system. Background technique [0002] The engine is a prime mover commonly used in industry and an active rotating structure in many occasions. The engine has experienced hundreds of years of development, from the initial external combustion to the current common internal combustion, which has been applied in various fields. [0003] In the prior art, the engine has only one working chamber, and the multi-cylinder engine is only stacked to superimpose the pistons, cylinders, etc. 1. The work of expansion is within a single stroke. Therefore, the initial stage of work of expansion is very high temperature. In order to relieve the high temperature, the engine often needs to be equipped with a reliable heat dissipation structure. From the overall analysis, the energy released by fuel combustion needs to be subtracted from the exhaust heat. ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the engine has only one working chamber, and the multi-cylinder engine is only stacked to superimpose the pistons, cylinders, etc. 1. The work of expansion is within a single stroke. Therefore, the initial stage of work of expansion is very high temperature. In order to relieve the high temperature, the engine often needs to be equipped with a reliable heat dissipation structure. From the overall analysis, the energy released by fuel combustion needs to be subtracted from the exhaust heat. 1. The heat discharged by heat dissipation and related mechanical losses are the working energy. High exhaust temperature and high heat dissipation mean that the efficiency of the whole machine is low. How to improve engine efficiency is a very economical technical problem.
