Abstract
A fuel atomizing valve and cooperative engine intake manifold are disclosed wherein the air volumetric capacity of the atomizing valve is infinitely varied automatically as a function of engine demand and without external controls. Intake manifold size and volumetric capacity are likewise varied automatically according to engine demand to assure delivery to all engine cylinders a cool dense homogeneous charge with superatomization of the fuel in a near molecular state.
Claims14
A fuel delivery system for piston engines comprising an intake manifold having a manifold passage for delivering an air-fuel charge to cylinders of an engine from an external air-fuel source, a variable capacity engine demand responsive atomizing valve connected in the manifold passage and being in communication with said source, said valve including a biased atomizing screen assembly and coating fixed screen covering means whereby movement of the screen assembly against the biasing means in response to increasing engine demand causes a progressively greater atomizing screen area to be uncovered in the manifold passage, and a manifold passage variable closure means carried by the screen assembly and moving therewith and progressively increasing the effective cross section of the manifold passage as engine demand increases.
A fuel delivery system for piston engines comprising an intake manifold having a manifold passage for delivering an air-fuel charge to cylinders of an engine from an air-fuel source, and a variable capacity engine demand responsive atomizing valve connected in said manifold passage and being in communication with said source, said valve including a yieldingly biased atomizing screen assembly and a coating fixed screen covering means whereby movement of the screen assembly against the biasing means in response to increasing engine demand causes a progressively greater screen area to be uncovered in the manifold passage, said fixed screen covering means comprising a pair of fixed concentrically spaced sleeves within the screen assembly with the outermost fixed sleeve engaging telescopically in the screen assembly in close relationship thereto, the innermost sleeve being spaced substantially from the atomizing screen wall of the assembly to define a substantial jump space between the bore of the innermost fixed sleeve and said screen wall.
