Fuel bowl

A carburetor system comprising:

• a fuel regulator configured to receive and deliver a gaseous fuel;
• a fuel bowl in fluid communication with said fuel regulator, said fuel bowl including a body having an interior and an exterior opposite said interior, a first side opposite a second side, a third side opposite a fourth side, and a bottom opposite at least one opening, said at least one opening configured to be in fluid communication with at least one of a carburetor and an adaptor and at least one fuel inlet port disposed in at least one of said first side, said second side, said third side, said fourth side, said bottom, and said at least one opening of said body, said at least one fuel inlet port configured to receive said gaseous fuel from said fuel regulator, wherein said gaseous fuel expands and contracts within said body;
• a final fuel metering restriction device disposed in at least one inlet supply port of at least one cylinder of at least one of said carburetor and said adaptor, said final fuel metering restriction in fluid communication with said opening of said fuel bowl;
• and
• a venturi disposed in said carburetor, wherein said venturi includes a venturi length and said final fuel metering restriction device are configured to cooperate with each other, said venturi having
• a restriction configured to draw said gaseous fuel into said carburetor system, mix said gaseous fuel with air and discharge a fuel air mixture for combustion, said restriction including a restriction diameter
• an air inlet coupled within said restriction, said air inlet configured to reduce a flow area from an air inlet first end to an air inlet second end;
• a fuel air outlet coupled within said restriction, said fuel air outlet configured to increase said flow area from a fuel air outlet first end to a fuel air outlet second end, said fuel air outlet first end proximate said air inlet second end;
• a throat coupled within said restriction between said air inlet second end and said fuel air outlet first end;
• a gaseous fuel supply passage in fluid communication within said restriction and proximate said throat, wherein said gaseous fuel supply passage is located between said air inlet first end and said fuel air outlet second end from 40 percent to 55 percent of said venturi length measured from said fuel air outlet second end;
• wherein the venturi length comprises a distance from said air inlet first end to said fuel air outlet second end;
• a ratio between said restriction diameter and said length comprising at most 1.38 to 1;
• and
• wherein said air inlet and said gaseous fuel supply passage are configured as one of said air inlet having a radius with said gaseous fuel supply passage formed as slots, said air inlet having a radius with said gaseous fuel supply passage formed as bores, and said air inlet having a taper with said gaseous fuel supply passage formed as slots;
• and
• wherein said fuel bowl is a non-vented container when coupled to and in fluid communication with at least one of said carburetor and said adaptor, and
• wherein the fuel bowl is configured to deliver and evenly distribute the gaseous fuel from the fuel bowl to multiple cylinders.

A fuel bowl comprising:

• a body having an interior and an exterior opposite said interior, at least one side defining said interior, and at least one opening, said at least one opening configured to be in fluid communication with at least one of a carburetor and an adaptor;
• and
• at least one fuel inlet port disposed in said at least one side of said body, said at least one fuel inlet port configured to receive a gaseous fuel from a fuel regulator, wherein said gaseous fuel expands and contracts within said body,
• wherein the fuel bowl is a non-vented container when coupled to and in fluid communication with a venturi and at least one final fuel metering restriction device of at least one of said carburetor and said adaptor, wherein the venturi and the at least one final fuel metering restriction device are configured to cooperate with each other, and
• wherein the fuel bowl is configured to deliver and evenly distribute the gaseous fuel from the fuel bowl to multiple cylinders.
