Thermal efficiency of a prime mover is a function of the delta T the engine operates over and is implemented in any engine using pressure change by a ratio of volume called compression ratio. That is why the diesel is the king and if the Bourke was available it would hold the crown. I think the stirling's claim to fame is solar or solid fuel. If you have a fuel that can be internally combusted efficiency says use a diesel. Kirk
