Abstract
1,259,653. Hot gas engines. ATOMIC ENERGY OF CANADA Ltd. Sept. 22, 1969 [Feb. 14, 1969], No.46598/69. Heading F1S. [Also in Division G6] A method of converting energy available in a thermal source into mechanical energy in a continuous closed cycle sequence utilizing a working medium which is at all times gaseous comprises: - (a) compressing the working medium in a first space having a lower mean temperature by a compression ratio "r" (b) adding heat at substantially constant pressure to the compressed medium, (c) adding further heat from the source to the compressed medium at substantially constant volume, (d) expanding the medium into a second space having a higher mean temperature and pressure by an expansion ratio 'R' where R is greater than r, (e) extracting an amount of heat nominally equivalent to Hr from the expanded medium at substantially constant pressure, the amount of heat Hr providing that heat required in step (b), (f) cooling the medium at substantially constant pressure and (g) utilizing the work done by the medium during the expansion step (d) to provide firstly that work required for the compression step (a) and secondly a mechanical output. The following gases were investigated as to their performance as working media in the engine: Air, Nitrogen, Carbon dioxide, Hydrogen, Helium, Argon, Sulphur Dioxide. Air and Carbon dioxide result in a better performance than the rest, with Carbon dioxide giving the best overall performance. The Fig. shows the piston on its upward stroke with the valve V 2 open. Hot gas is displaced into the cooler through the regenerator. In the space below the piston cool gas from the cooler is sucked in. On the downard stroke the gas to which heat energy has been added in the heat source expands. In the space below the piston the cool gas which has been sucked in is compressed and displaced into the heater through the regenerator, the valve V 4 being open.
