Problems solved by technology

[0002] Under the premise of a certain working fluid pressure and a certain temperature difference between the hot and cold ends, the main factors affecting the performance improvement of the hot air machine are the heat shuttling loss of the hot and cold end working fluid back and forth, and the useless volume loss. The volume of the traditional heater passes through the regenerator. The volume and the volume of the cooler are connected to each other, that is to say, when the heater heats and expands the working medium in the expansion chamber to push the p...

Abstract

The invention discloses an efficient double-piston hot-air engine. The efficient double-piston hot-air engine comprises an expanding cavity and a compression cavity, wherein the expanding cavity communicates with the compression cavity through a heat regenerator; an expanding piston is arranged in the expanding cavity; a compression piston is arranged in the compression cavity; the expansion piston and the compression piston are separately connected with a power output end; a heating counter bore and a cooling counter bore are separately formed in the expanding cavity and the compression cavity; a heater sealing door is arranged in the expanding piston; a heater compression spring is arranged in a heater sealing door mounting cavity; a cooler sealing door is arranged in the compression piston; a cooler compression spring is arranged in the cooler sealing door mounting cavity; and cylindrical grooves which communicate with the heat regenerator are separately formed in the expanding piston and the compression piston. After the structure is adopted, the purpose that the volume of a cooler is closed during working by heating and the volume of a heater is cooled during cooling compression is realized; besides, a phase angle between crankshafts on the power output shaft can be fine adjusted, so that the engine reaches the optimal working state.

Description

technical field [0001] The invention relates to a double-piston heat engine, in particular to a high-efficiency double-piston heat engine. Background technique [0002] Under the premise of a certain working medium pressure and a certain temperature difference between the hot and cold ends, the main factors affecting the performance improvement of the hot air machine are the heat shuttling loss of the hot and cold working medium airflow back and forth, and the useless volume loss. The volume of the traditional heater passes through the regenerator. The volume and the volume of the cooler are connected to each other, that is to say, when the heater heats and expands the working medium in the expansion chamber to push the piston to do work, another part of the high-temperature working medium gas is neutralized and cooled by the cooler through the regenerator, which is wasted and mainly useless The volume includes the sum of heater volume, regenerator volume, and cooler volume,...
