Abstract
An adapter for coupling microwave energy or both microwave and spark energy into the combustion chamber of a gasoline engine through the chamber spark plug comprising a sleeve adapted at one end to be tightly received over the spark plug insulator housing, and a connector carried at the opposing sleeve end and adapted for connection to a spark plug lead for transmitting spark energy to the spark plug electrodes. A microwave antenna is carried externally of the sleeve for transmitting microwave energy in a waveguide mode through the sleeve and through the insulator housing into the engine chamber while substantially bypassing the spark energy conduction path. The antenna, which may comprise a square loop antenna disposed in a plane parallel to the sleeve and spark plug axes, is adapted to be coupled to a source of microwave energy for monitoring of engine ignition events, etc.
