    Abstract: A gaseous fuel-air mixer includes an outer shell, an inner shell, and a fuel chamber rib. The outer shell includes an air intake and a fuel intake. The air intake is configured to receive air. The air intake has an air outlet. The fuel intake has a fuel inlet that is configured to receive fuel. The inner shell includes an inner shell intake that is configured to separately receive the air from the air outlet and the fuel from the fuel intake and to provide a gaseous fuel-air mixture. The inner shell cooperates with the outer shell to define a fuel intake collecting chamber that is configured to receive the fuel from the fuel inlet and a fuel intake concentrating chamber that is configured to receive the fuel from the fuel intake collecting chamber and provide the fuel to the inner shell intake.

    Abstract: A multi-fuel carburetor with gas switching valve structure includes a carburetor body having a throat; a gas jet pipe formed on the carburetor body, the gas jet pipe having one end extended to the throat to connect with it and another end extended out of the carburetor body; and a gas switching valve and a gas adjustor mounted on the carburetor body respectively, the gas switching valve having one end mounted on the carburetor body to connect with the gas jet pipe and another end connected with the gas adjustor, and the gas switching valve having a gas measurement hole for measuring the flow rate of gas. A gas jet pipe is added to provide multiple choices for multiple fuels. Further, a gas measurement hole is set on the switching valve, thus it's easy to choose the corresponding position to meet the gas demand for the engine.

    Abstract: An insert for engine intake gaseous fuel mixing device. A body defines a longitudinal axis, leading end, trailing end, and exterior surface profile from the leading to the trailing end. Supports extend radially from the body, each support extending parallel to the axis to define separate longitudinal intake passages. The exterior surface profile of the body includes a nose section in which diameter increases from a minimum value at the leading end to a maximum value at a downstream end of the nose section. The nose section is followed by a flat section and a curved tapering section in which the profile converges toward the axis at an increasing rate from the flat section in a direction of the axis toward the trailing end. The diameter at the trailing end is at least 15 percent less than a maximum diameter of the body.

    Abstract: A system and method controls a flow of vent gases to a combustion engine. The system includes an inlet for receiving the vent gases, a pressure relief device that enables the vent gases to escape to atmosphere when a pressure in the inlet exceeds a predetermined relief pressure, a flow-restricting orifice, and a back pressure regulator disposed downstream of the orifice. A shut-off valve disposed between the back pressure regulator and the air intake is set to only open when an intake pressure falls below a predetermined negative intake pressure.
