Problems solved by technology

[0002] Traditional internal combustion engines generally discharge high-temperature exhaust gas directly, resulting in serious heat loss
However, the gas working medium in the traditional heat engine needs heat to heat, the conventional heating method is external combustion, and the fuel usage efficiency is also low. Therefore, for the fuel efficiency of the existing internal combustion engine and heat engine, it is necessary to provide Engines for further utilization of waste heat from engine exhaust

Abstract

The invention discloses a three-cylinder hot-air engine. The three-cylinder hot-air engine comprises two cylinder piston mechanisms, the two cylinder piston mechanisms are provided with air inlets and air outlets, and the two cylinder piston mechanisms are communicated through two reciprocation communication channels. One of the cylinder piston mechanisms in combustion engine burning action stroke is used as a hot cylinder of a Stirling engine, and the other cylinder piston mechanism is used as a cold cylinder of the Stirling engine, wherein gas working media for Stirling circulation are high-temperature gas after burning action stroke. Thus, a combustion engine and the Stirling circulation can be combined organically, and system heat efficiency can be improved greatly.

Description

technical field [0001] The invention relates to the field of thermal power, in particular to a heat engine. Background technique [0002] Traditional internal combustion engines generally discharge high-temperature exhaust gas directly, resulting in serious heat loss. However, the gas working medium in the traditional heat engine needs heat to heat, the conventional heating method is external combustion, and the fuel usage efficiency is also low. Therefore, for the fuel efficiency of the existing internal combustion engine and heat engine, it is necessary to provide a An engine that further utilizes the waste heat from the engine exhaust. Contents of the invention [0003] In order to solve the above problems, the technical scheme proposed by the present invention is as follows: [0004] Scheme 1: A three-type door hot gas engine, including a cylinder-piston mechanism A and a cylinder-piston mechanism B, the cylinders of the cylinder-piston mechanism A and the cylinders ...
