  • Gaseous fuel-air mixer with higher mixture uniformity
    Patent number: 12292018
    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.
