External combustion engine and transmission mechanism thereof

Abstract

The invention discloses an external combustion engine and a transmission mechanism thereof. The external combustion engine comprises a hot gas assembly, the transmission mechanism and a crankshaft; the hot gas assembly comprises four groups of heaters, heat regenerators and coolers and four cylinders arranged in a rectangle; disconnected cold and hot cavities are formed in each cylinder; each hot cavity is communicated with a cold cavity gas circuit of a group of heater, heat regenerator and cooler and the other cylinder to form a gas passage; the transmission mechanism comprises a swinging rod group and a connecting rod group; the swinging rod group comprises a first swinging rod and a second swinging rod, the swinging planes of which are mutually parallel; the connecting rod group comprises four connecting rods, namely a first connecting rod and a second connecting rod with equal length, and a third connecting rod and a fourth connecting rod which are extended downwards from a second pivot and a first pivot respectively and have equal length; and the upper ends of the third connecting rod and the fourth connecting rod are hinged with the first connecting rod and the second connecting rod respectively, and the lower ends of the third connecting rod and the fourth connecting rod are hinged with a connecting rod neck of the crankshaft. The external combustion engine has low cost, and is convenient 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...
