Abstract
The invention disclosed herein is a cyclic power mechanism including means providing for a variable dwell between cycles of the mechanism. The mechanism produces energy during each cycle and stores the energy of each cycle for consumption. The variable dwell between cycles is terminated and a new cycle is initiated upon the consumption of a preestablished portion of the stored energy. A preferred embodiment of the mechanism is a free piston engine operation on an Otto cycle. The piston of the engine is restrained after each combustion cycle as the energy of that combustion is stored for use. When a preestablished portion of the stored energy has been consumed, the piston is released and forced into another compression and combustion cycle for further storage of the combustion energy.
