Abstract:

A plurality of ultrasound engine whistles used in an internal combustion engine. The whistles may be placed inside a carburetor, inside a cylinder head, around an engine valve stem and other locations inside the engine. The whistles provide for greatly improved air fuel mixture prior to ignition. Also, the whistles allow for increased engine performance and acceleration, improved fuel mileage and a cleaner burning air fuel mixture for reduced fuel emissions into the environment. The ultrasound whistles include a whistle body having a first end portion and a second end portion. A whistle hole with whistle lip therearound is formed in the first end portion of the whistle body. The whistle hole has a depth in a range of 0. 032 to 0. 050 inches. Also, the whistle hole has a diameter in a range of 0. 031 to 0.

Abstract:

A firing apparatus includes a firing pin on a longitudinal axis and biasing means to urge the pin in a firing direction. A central trigger body with a pull end and base end extends along the axis and includes a fruste-conical surface surrounding the axis and expanding toward the base end to a base edge. An outer trigger body includes a base portion having a sheath with an inner cylindrical surface surrounding the inner body and extending to a base edge. Cooperating screw threads on the inner and outer bodies allow adjustment of the bodies longitudinally, one relative to the other, such that the inner and outer base edges are separated by a selected longitudinal distance. A sear for restraining the firing pin has a head with a face abutting the fruste-conical surface and a back surface opposing the cylindrical surface such that, only when a sufficient longitudinal pulling force is exerted upon the trigger body, the sear head is squeezed between the base edges to release the trigger body from the sear, displacing the head away from the axis and thereby freeing the firing pin to move in the firing direction.
