Abstract
We had developed and designed original gamma-type circulating flow stiffing engine (CFSE) with two lead valves in operating gas flow, for application of waist heat recovering. Meanwhile, present CFSE prototype has new pulse converters in substitution for the lead valves. Though the pulse converters are incomplete preventing reverse flow compared with lead valve, they are simpler, low pressure loss and wide section area. A method of pulse converter, valve less design applied for present CFSE with two-cylinders, 600W electric output by linear motor- generator, and prediction of the performance in low temperature differential cases are introduced.
