Abstract

The invention relates to the technical field of reducing mechanical friction loss energy of external combustion engines, and discloses an external combustion engine for reducing mechanical loss energyby using the characteristics of thermal expansion and cold shrinkage. The external combustion engine comprises a shell, a sliding groove is formed in the shell, the surface of the sliding groove is slidably connected with a piston, the surface of the piston is fixedly connected with a shaft rod, energy storage grooves are formed in the portions, on the two sides of the piston, in the shell respectively, storage grooves are fixedly connected in the energy storage grooves, and diversion layers are formed in the surfaces of the storage grooves. Spring plates are movably connected with the tops of the storage grooves, push rods are movably connected with the surfaces of the spring plates, toothed plates are movably connected in the push rods, gears are movably connected with the surfaces of the toothed plates, connecting plates are movably connected with the surfaces of the gears, and twisting rods are fixedly connected with the surfaces of the connecting plates. The deflecting directionof booster rods is identical to the moving direction of the shaft rod, therefore, the force of the booster rods can neutralize the friction resistance generated during mechanical movement, and the effect of overcoming the friction resistance by using a thermal-shrinkage and cold-expansion material is achieved.

Description

technical field [0001] The invention relates to the technical field of reducing mechanical frictional energy loss of an external combustion engine, in particular to an external combustion engine that utilizes thermal expansion and contraction characteristics to reduce mechanical energy loss. Background technique [0002] The external combustion engine uses fuel combustion to heat the circulating working medium, such as a steam engine that transports the high-temperature and high-pressure water vapor generated by heating the water in the boiler to the inside of the machine to convert heat energy into mechanical energy. The typical work is the Stirling engine. The Stirling engine was invented by Stirling in 1816, which can avoid the problems of cylinder shock and insufficient combustion caused by internal combustion engines. [0003] With the continuous development of industrial technology, external combustion engines have been used in various fields, but the disadvantage of e...

Problems solved by technology

[0003] With the continuous development of industrial technology, external combustion engines have been used in various fields, but the disadvantage of existing external combustion engines is that while heat energy provides mechanical motion, part of the capacity is used to overcome various problems when mechanical equipment moves. The friction between parts and the resistance generated by friction will reduce the working effect of mechanical energy, and the existing technology adopts the method of artificially overcoming or increasing heat energy, which cannot fundamentally solve the problem. The external combustion engine with mechanical loss came into being
