1. An injection plate assembly for an internal combustion engine that includes a manifold and carburetor or throttle body, for injection of a primary fuel and an accelerant into a throttle bore of the manifold, the injection plate assembly comprising:

  • a lower plate having a main aperture adapted to be aligned with a throttle bore of the manifold, with fuel runners defined in the lower plate for carrying the primary fuel from fuel inlet ports to the main aperture;

    an intermediate plate located on the lower plate that includes an aligned main aperture, and a plurality of fuel injection ports are defined in a lower face of the intermediate plate which established a fluid path with the fuel runners in the lower plate in order to allow fuel to be injected into the main aperture;

    an upper plate located over the intermediate plate that includes accelerant runners in fluid communication between accelerant inlet ports and injection gates located around a main aperture in the upper plate, the main apertures in the lower plate, intermediate plate and upper plate are aligned with the throttle bore of the manifold in order to inject a high pressure accelerant and fuel into the main aperture, the injection gates in the upper plate are located above and in aligned positions with the fuel injection ports defined between the intermediate plate and the lower plate forming a plurality of fuel injection port/accelerant gate pairs, and in order to equalize injection of both the primary fuel and the accelerant, the lower plate includes the fuel inlet ports that deliver the primary fuel via the fuel runners at opposing sides of the lower plate, the accelerant inlet ports deliver the accelerant via the accelerant runners at opposite sides of the upper plate, with the accelerant inlet ports being located on different sides of the injection plate assembly from the fuel inlet ports.
