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 the external combustion type, and the fuel use efficiency is also low. Therefore, in order to improve the fuel use efficiency of the existing internal combustion engine and heat engine, it is necessary to provide a fuel Use an efficient engine

Abstract

The invention discloses a cylinder internal combustion Stirling engine which comprises two cylinder piston mechanisms and a cooler. Cylinders of the two cylinder piston mechanisms are communicated through a reciprocating channel, and the reciprocating channel is provided with a heat regenerator. An internal combustor is arranged inside at least one cylinder of the cylinder piston mechanisms, and the internal combustor is provided with a fuel feeding mechanism. An air distribution opening is arranged at least at one position of being on the cylinders of the cylinder piston mechanisms and in the reciprocating channel, and an air valve is arranged at the position of the air distribution opening. A reciprocating air distribution valve is arranged at the position of a reciprocating air distribution opening where the cylinder piston mechanisms of the internal combustor and the reciprocating channel are communicated. According to the cylinder internal combustion Stirling engine, the circulation of a combustion engine and the circulation of a thermomotor are combined, and so that the thermal efficiency of the engine is improved. The cylinder internal combustion Stirling engine is beneficial to energy saving, simple in structure, and strong in practical applicability, thereby having a wide application prospect.

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.
