  • Fuel and air charge forming device
    Patent number: 12429019
    Abstract: A charge forming device for a combustion engine includes a throttle body having a throttle bore, an air passage having at least a portion in which air flows separate from the throttle bore and a throttle valve with a valve head movable relative to the throttle body. A nozzle body has a fuel passage and a feed passage, the fuel passage is arranged to receive fuel that exits a fuel outlet of a fuel metering valve, and the fuel passage is communicated with a fuel chamber through which fluid flows into the throttle bore, and the feed passage is communicated with the air passage to receive air from the air passage and the feed passage is communicated with the fuel passage upstream of the fuel chamber, wherein air in the feed passage is mixed with fuel in the fuel passage upstream of the fuel chamber.

  • Fuel and air charge forming device
    Patent number: 11802529
    Abstract: A throttle body has a throttle bore with an inlet, an outlet and an air passage. A throttle valve has a valve head received within the throttle bore. A fuel metering valve is mounted on the throttle body and has a valve element and a fuel outlet, the valve element is movable relative to a valve seat to control fuel flow through the fuel outlet. And the nozzle body is carried by the throttle body and has a fuel passage and a feed passage. The fuel passage is arranged to receive fuel that exits the fuel outlet, and is communicated with a fuel chamber through which fluid flows into the throttle bore. The feed passage is communicated with the air passage and with the fuel passage upstream of the fuel chamber. Air in the feed passage is mixed with fuel in the fuel passage upstream of the fuel chamber.
