  • Engine testing microwave transmission device
    Patent number: 4403504
    Abstract: A microwave transmission device for transmitting microwave signals into and out of the combustion chamber of a spark ignited internal combustion engine. The device comprises a circular metallic waveguide that is adapted to encompass a resistor-type spark plug of the engine. An antenna element is disposed in the waveguide which excites it in the TE.sub.11 mode whereby the internal resistor does not substantially attenuate microwave transmission. The waveguide has means for securely attaching it to the exterior of the spark plug such that the waveguide and spark plug have a common longitudinal axis.
