GASEOUS FUEL MIXER FOR INTERNAL COMBUSTION ENGINE
First Claim
1. An internal combustion engine, comprising:
- an intake circuit including a mixer passage having a mixer passage axis and a gaseous fuel mixer positioned within the mixer passage and extending along the mixer passage axis, the gaseous fuel mixer including a frustoconical cone and an outlet element;
the frustoconical cone including a first end, an open second end having a diameter D and positioned downstream from the first end, an interior portion, and a height H, the outlet element being positioned in the interior portion and including a fuel passage and a plurality of transverse openings connecting the fuel passage to the interior portion, the plurality of transverse openings positioned in the interior portion to direct gaseous fuel into the interior portion; and
a gaseous fuel system connected to the intake circuit.

Abstract
A gaseous fuel mixer for an internal combustion engine includes a frustoconical cone and an outlet element extending from the frustoconical cone at an interior portion of the frustoconical cone. The outlet element and the frustoconical cone are located within a mixer passage of an intake system. The mixer passage has an internal diameter. The outlet element includes a plurality of transverse openings that connect a fuel passage formed within the outlet element to the interior portion of the frustoconical cone. The height and diameter of the frustoconical cone and the internal diameter of the passage form specific ratios that provide for uniform mixing of intake air and gaseous fuel prior to the mixture flowing into an intake manifold of the engine.
