External combustion engine and transmission mechanism thereof

Abstract

An external combustion engine comprises a hot gas assembly, a transmission mechanism and a crankshaft (7). The hot gas assembly comprises four heater / regenerator / cooler (HRC) groups and four cylinders (11, 12, 13, 14), said cylinders being arranged in a rectangular array. Each cylinder is provided with a hot chamber (112, 122, 132, 142) and a cool chamber (113, 123, 133, 143). The hot chamber and cool chamber are not in communication with each other. Each hot chamber is in communication with one HRC group and with a cool chamber gas conduit of another cylinder, thereby forming a gas passage. The transmission mechanism comprises a set of swing rods and a set of connecting rods, wherein the set of swing rods comprises a first swing rod (51) and a second swing rod (52) in mutually parallel swing planes, and wherein the set of connecting rods comprises four connecting rods. A first connecting rod (61) and a second connecting rod (62) having the same length extend downwards or upwards from a second pivot shaft (54) and a first pivot shaft (53), respectively. The upper ends or the lower ends of a third connecting rod (63) and a fourth connecting rod (64) having the same length are hinged with the first connecting rod (61) and the second connecting rod (62), respectively, whereas the lower ends or the upper ends thereof are hinged with a connecting rod neck (72) of the crankshaft (7). The external combustion engine is low in cost and easy to manufacture.

Description

technical field

[0001] The invention relates to an engine, in particular to an external combustion engine and its transmission mechanism. Background technique

[0002] The external combustion engine is a closed cycle reciprocating piston heat engine with external combustion. Because it was invented by Stirling in Scotland in 1816, it is also called the Stirling engine, also known as the heat engine. The medium substance (usually high-pressure gas) that transfers energy in the external combustion engine is called working medium, and can be filled with the working medium of certain volume in one, two, four or more closed cylinders. One end of the cylinder is a hot chamber and the other end is a cold chamber. The working medium is compressed in the low-temperature cold chamber, and then flows into the high-temperature hot chamber to be heated rapidly and expand to do work. The heat brought by the continuous combustion of the fuel in the combustion chamber outside the cylinder...
