ABSTRACT:
The prime mover is a high power output, environmentally clean, efficient, multi-fueled, external combustion, closed regenerative cycle piston engine with practically no dirt ingestion and minimal acoustic, thermal and smoke signatures. The engine consists of five major units: the heat exchanger, heater, accumulator, compressor and power units. The engine operates on one power stroke per revolution with an unidirectional mass flow of the working fluid decreasing engine design complexity. The engine's design concept incorporates a flexibility in the choice or design of the major units, and, therefore, offers an efficient and practical maintenance and repair program. The unique heater units have the capability of developing different types of thermodynamic cycles while using a variety of working fluids. The engine can be fabricated with off-the-shelf materials, ceramics or other adiabatic types of high temperature materials.
