給油ノズル①Liquid mixture of gasoline
and air, are refueling fromthe nozzle tip.
②Gasoline liquid enters into thefuel tank, also already met thefuel in the tank is mixed with air.
③Fuel tank space is filled with airthat is entrained by the existedvapor and dispensing nozzle.
④And it filled the vapor is pushed
out from the fuel tank to the gas
vent pipe.
⑤And filled the vapor is passed
through the gas vent pipe, it will
be discharged from the fuel filler
to the atmosphere.
