Abstract:
1. A combustion chamber system for a combustion-powered linear motor comprising: a primary combustion chamber in communication with a secondary combustion chamber; first and second openings between the primary and secondary combustion chambers; a spark igniter located within the primary combustion chamber and arranged for generating a flame front and an accompanying faster moving compression wave; the primary combustion chamber being shaped for guiding the compression wave along a path through the first opening from the primary combustion chamber into the secondary combustion chamber in advance of the flame front; the primary combustion chamber also being shaped to support propagation of the flame front for forcing unburned fuel and air in advance of the propagating flame front; and the secondary combustion chamber being shaped for reflecting the compression wave back through the first opening into the primary combustion chamber in a direction that compresses the unburned fuel and air advanced by the propagating flame front and that discharges the flame front through the second opening into the secondary combustion chamber for accelerating combustion.
