Abstract
An axial piston type internal combustion engine of novel three cycle variety, wherein the complete combustion process within the combustion chamber consists of three distinct cycles, accomplished over two distinct strokes of each piston, the three cycles being: the high pressure charging cycle, the power cycle, and the postive total exhaust expulsion cycle. The aspiration is controlled by a rotary disc valve, while the fresh gas charge is pre-compressed to high pressure by a separate high pressure charger. The conventional intake stroke and compression stroke, normally directly or indirectly carried out by the power piston in conventional two stroke or four stroke engines, is entirely divorced from the functions of the power piston and its power train components. Intended to replace conventional engines when high specific output, high power to weight ratio, and economy of operation are paramount.
