Abstract

The invention discloses an improved miniature hot air engine, comprising a heater and an air cylinder which is arranged on a crank case, wherein a power piston in the air cylinder is connected with a crank through a connecting rod, an air distribution piston is installed in an air distribution cylinder in a matching manner, the heater is connected with the air distribution cylinder into a whole, a metal-shell cylindrical air distribution piston of which the external end surface is provided with an air vent is installed in the air distribution cylinder in a clearance fit manner, a piston rod fixedly connected on the external end face of the metal-shell cylindrical air distribution piston extends out of the air distribution cylinder and is in movable fit with a fit through hole arranged on the external end face of the air distribution cylinder in a sealing manner, the other end of the connecting rod hinged with the piston rod is hinged with one end of a V-shaped lever hinged on a fixed hinged point, the connecting rod hinged with the other end of the V-shaped lever is connected with the crank, an airway tube is connected with an air distribution hole arranged on the air distribution cylinder, and the other end of the airway tube is connected with an air cylinder cover air distribution hole of the air cylinder. The improved miniature hot air engine has simple structure, low manufacturing cost, low requirement condition on heat source for heating and wide applicable fuel range, and can use fire coal, crop straws and other solid fuels besides fluid fuel.

Description

technical field [0001] The invention belongs to an external combustion heat engine, in particular to an improved small heat engine. Background technique [0002] A heat engine is a closed-cycle reciprocating engine in which gas is periodically compressed and expanded at different temperatures by external heat supply. The power transmission mechanism of the heat engine generally adopts crank connecting rod transmission. A traditional heat engine generally has two pistons, the gas distribution piston and the power piston. When the hot air machine is working, the gas distribution piston reciprocates in the heater, regenerator and cooler to play the role of gas distribution. The power piston compresses the working medium, and at the same time, when the working medium is heated and expands, the working medium pushes the power piston to do work through the crankshaft of the connecting rod. At present, the structure of a kind of heat engine is that the gas distribution cylinder ...
