Air supplemental heat transfer engine

Abstract

The invention discloses an air storing and heat exchanging engine, mainly comprising hot air cylinder, heater, air storing room I, compressor and air storing room II. The compressor is connected with the cooling system. When the engine works, the high-temperature heat source transfers heat to the air in inner cavity of heater pipes and on the cover of heat cylinder there is a microcomputer control valve mechanism. The theoretical cycle of engine comprises two equal temperature processes, two equal cubage processes and a moving process. In the moving process energies can not be exchanged in system and the work that the outside puts to system is zero. So the cycling efficiency is equal to carnot cycle efficiency. Compared with the linkage-crank internal combustion engine the open engine, which works in the cycle, can save energy by more than 10%. Compared with prior stirling engine the transmission structure of closed engine is simple.

Description

Technical field [0001] The invention relates to an engine, especially an air storage type heat exchange cycle engine whose theoretical thermal efficiency is equal to the efficiency of the Carnot cycle. Background technique [0002] Internal combustion engines are widely used in various machinery or transportation machinery that needs to move. The theoretical cycle efficiency of the existing internal combustion engines is lower than the Carnot cycle efficiency, and the current internal combustion engines mainly use a connecting rod crank mechanism to convert the movement of the piston into rotation. This reciprocating mechanism has problems such as large sliding friction losses, so The efficiency is only 30% to 40%. In recent years, engines without connecting rod crank mechanisms have been studied both at home and abroad, such as microcomputer-controlled rack engines, 0410022121.2, rolling screw engines, ZL01214405.3, ZL02221857.2, all of which have problems such as lower th...

Problems solved by technology

In addition, the ideal motion of the engine piston is a continuous motion, so the external heating closed engine of the present invention can solve the technical problem that the ideal motion of the piston in the existing heat engine is a discontinuous motion.
