ABSTRACT:
A spark plug adapter has a tubular member provided with an enlarged upper portion internally threaded to receive a spark plug and the spark gap thereof and a smaller lower portion externally threaded and adapted for threading into a spark plug receiving bore of an internal combustion engine there providing a preliminary combustion chamber with an enlarged upper portion surrounding the spark gap and with a smaller lower portion opening into the internal combustion engine. The spark plug adapter is further provided with a relatively thin transverse member which extends diametrically across the tubular member below the spark gap for dividing the preliminary combustion products into two separate and substantially equal streams and to impart a turbulence thereto as they pass into the internal combustion engine. The lower portion of the tubular member terminates in an annular ledge providing a restricted opening for the passage of preliminary combustion products from the preliminary chamber into the internal combustion engine and the transverse member is spaced from said ledge and supported thereon by support means extending upwardly therefrom along and adjacent the wall of said lower portion up to said transverse member.
