ABSTRACT:
An Ericsson-Stirling type engine is disclosed having a semi-open regenerative working fluid system employing intermittent internal combustion. The regenerator is modified to act also as a catalytic combustor and is located at the terminal end of the unswept clearance volume most adjacent the high temperature chamber or hot swept space. The clearance volume is reduced and engine efficiency increased by (a) elimination of any leak path around the regenerator (b) positive exhaust purging, and (c) lower peak combustion temperature.
