  1. Two cylinders at each end of a sliding shaft with a generator coil between. Pistons fire alternately to move the coil back & forth. Control provided by electronics so no crank and no cams.

  2. What about the voice coil direct injection 2 stroke? The coil injects a premixed rich air fuel load after the ports have closed. Tumbling air in the cylinder filters the rich primary fuel load. Variable valve controls the exhaust port timing and Reed valves control inlet air flow. Basically uses the primary air secondary air arrangements found in continuously fired biller burners.
