I was wondering if periodically closing the air intake during a burn, when closed, it generates a vacuum on dying burnt fuel, but the concept seems to me that it's the same as rotation in a circle, simple harmonic motion, or a piston going up and down, and if that could be used in an engine.
I designed a cylinder for an opposed force engine, the two pistons are half-hemispheres, that move laterally to the direction of the up-down cylinder (the drawing should show two pipes both perpendicular at the level where the two pistons are to accomodate their lateral movement). My question...
