Abstract:
1. An injection plate assembly for an internal combustion engine that includes a manifold and a carburetor, for injection of a primary fuel into each throttle bore of the manifold having at least one throttle bore, and for injection of a secondary fuel thereinto for admixture with the primary fuel, comprising: an assembly including a lower plate having a lower surface to be adjacent a manifold, an upper plate having an upper surface to be adjacent a carburetor, and an intermediate plate interposed between the lower plate and the upper plate, the assembly having at least one aperture therethrough aligned with each respective throttle bore; the lower plate including an inlet port for the primary fuel, and a runner in fluid communication with the inlet port and extending to an array of primary injection gates about each of the at least one apertures of the assembly; the upper plate including an inlet port for the secondary fuel, and a runner in fluid communication with the inlet port and extending to an array of secondary injection gates about each at least one aperture of the assembly; one or more of the secondary injection gates of the upper plate being associated with one or more respective primary injection gates of the lower plate to define peripherally spaced apart groupings of gates located around the at least one aperture, in each of the groupings of gates, at least one of the secondary gates is peripherally offset from at least one of primary gates that is positioned thereabove, with the at least one of the primary gates being oriented in a direction toward the at least one primary gate in the grouping of gates; and the secondary injection gates each defining a discharge angle for the secondary liquid distinctly downwardly into the throttle bore associated with each of the at least one apertures while the primary injection gates each discharge the primary fuel into an atomized spray plume of secondary liquid discharged from the associated secondary injection gate or gates, whereby the primary fuel is also atomized and induced into the throttle bore.
