External combustion engine with Stirling open Cycle

Industrial engines using open cycles are generally described in terms of Otto or Diesel cycles. We are attempting to develop an open-cycle engine approximating the Stirling cycle, while conserving external combustion. Our open-cycle Stirling engine is- being built on a motorcycle Vengine; of course the heat exchangers have been designed from scratch. Some thermodynamic considerations justifying the use of the open cycle have been developed. A numerical simulation of the proposed open cycle has been carried out. An optimization of the heat exchanging system has been attempted, making use of an entropic parameter. By now, the complete design of the experimental motor has been carried out, waiting for experimental testing to verify the cycle effectiveness and the optimization criteria.
