• FIG. 1 is a functional block diagram of the engine control system;
• FIG. 2 is a cycle sequence and timing diagram including schematic representations of the compressor and expander sections and the positions of the various cylinders during or at various points in the cycle;
• FIGS. 3, 4 and 5 show that engine can be designed to use single, double or triple lobe cam track embodiments;
• FIG. 6 is a longitudinal cross-section view through the axis of the engine to show specific features of construction and to further illustrate the operating principal thereof in an embodiment having single compressor and expander banks of pistons;
• FIG. 7 is a simplified cross-sectional view through the compressor section of the engine;
• FIG. 8 is a simplified cross-section view of the engine through the expander bank of cylinders;
• FIG. 9 shows an alternative embodiment with a single bank of pistons which act as both compressor and expander; and
• FIG. 10 shows an alternative embodiment with double banks of pistons in the compressor and expander sections.
