Method and apparatus for igniting air-fuel mixture in an engine

Abstract From the Canadian patent

A method and apparatus for igniting the air-fuel mixture within a rotary combustion engine. A primary transformer core half and its primary winding are positioned in the upper cover plate of a Wankel rotary engine. Three spark plugs are electrically connected to their own secondary transformer core halves and secondary windings in a hollow rotor piston. The transformer core halves are arranged so that whenever the rotor is in correct position for ignition to occur (around T.D.C.) the primary transformer core half and one secondary transformer core half are in proper alignment for magnetic flux coupling between the two transformer core halves. When so coupled high voltage necessary, for …
