ABSTRACT:
The four cycle external combustion closed regenerative cycle piston engine is an environmentally clean, multi-fueled, efficient, conventional designed device. The engine consists of four major units: the heater, heat exchanger, accumulator, and power units. The engine operates on one power stroke per two revolutions with an unidirectional mass flow of the working fluid minimizing complexity. Each valve of the power unit's four valves per cylinder communicates to its respective major unit, synchronously opening/closing with the piston's position in the power unit cylinder. The intake and compression stroke of the four cycle engine is synchronized with the intake and compression valves and performs the function of a compressor unit reducing the size, weight, cost and complexity of the engine.
