ABSTRACT:
A piston type internal combustion engine of novel three cycle variety, in which the intake and compression functions are divorced from the combustion cylinder entirely and are carried out by a separate high pressure compressor; with a high pressure charging cycle, a power cycle and an exhaust cycle carried out in the combustion chamber in a positive manner. The gas charge is pre-compressed to maximum permissible value and injected into a varying volume combustion chamber, without any appreciable change in pressure. Power output is varied by varying the initial volume of the combustion chamber. Executed in radial cam driven and crank driven versions. Intended to replace conventional variable output engines.
