摘要： A plurality of ultrasound whistles (24) formed into a ceramic core (22) of a conventional spark plug (10) used in a cylinder of a gasoline combustion engine for greatly improved air fuel mixture prior to ignition. The spark plug (10) with ultrasound whistles (24) provides for increased engine performance and acceleration, improved fuel mileage, and an improved air fuel mixture thereby reducing fuel emissions into the environment. The ultrasound whistles (24) are constructed in the form of whistle holes (26). The whistle holes (26) are disposed around a circumference of the ceramic core (22) in a spaced relationship from the spark plug's electrode (20). Around the top of the small closed end whistle holes are upwardly extending lips (28). The combined structure of the whistle holes (26) and the upwardly extending lips (28) increase the speed of the air fuel mixture creating a more homogenous air fuel mixture before and during ignition in the engine cylinder.
