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 spark plug firing is induced in the secondary winding whenever the primary winding is excited with an alternating current generated by a gated power oscillator. The high voltage induced in the secondary winding is permitted to form a spark across the spark plug gap as long as the primary winding is so excited and the transformer core halves are magnetically coupled.
An ignition assembly in combination with a rotary piston engine having a triangular piston which has three corners and which rotates within a housing whose internal cross section is epitrochoid in shape, a combustion chamber being formed by first and second corners of the triangular piston and a predetermined portion of the housing, both first and second corners being adjacent the predetermined portion of the housing, said ignition assembly comprising:
An ignition assembly in combination with an internal combustion engine having first and second components which define a combustion chamber and move through repetitive cycles relative to one another, said ignition assembly comprising:
A method for igniting a fuel-air mixture in an internal combustion engine having a first component and a second component which define a combustion chamber and which move through repetitive cycles relative to one another, the first component having attached to it a first half of a transformer core and its primary winding and the second component having attached to it a second half of a transformer core and its secondary winding such that the core halves are in proper alignment for magnetic flux coupling during a predetermined portion of the relative movement, the secondary winding being electrically connected to a spark plug whose electrodes extend into the combustion chamber, said method comprising the steps of moving the first and second components through one cycle including the predetermined position and energizing the primary winding with an alternating electric current.
