摘要： An apparatus for detecting a vehicle having a vapor recovery system having a fuel dispenser configured to deliver fuel to a fuel tank of a vehicle, a vapor recovery system operatively associated with the fuel dispenser having a vapor path for removing fuel vapor expelled from the fuel tank of the vehicle during a fueling operation, and a hydrocarbon vapor sensor associated with the vapor path for sensing the fuel vapors in the vapor path, wherein when the vapor sensor does not sense fuel vapor during the fueling operation, the fuel dispenser determines the vehicle contains an onboard vapor recovery system. Once a vehicle having an onboard vapor recovery system is detected, the vapor recovery system is either shut off or adjusted during the fueling operation to minimize fugitive emissions.

摘要： An apparatus for dispensing volatile liquid fuel with recovery of fuel vapors includes a fuel delivery system having a fuel delivery line and a pump in the line to pump fuel there-along to a nozzle. A vapor recovery subsystem includes a vapor return line from the nozzle and a vapor impulsion means to induce vapor to flow through the vapor return line at a vapor flow rate comparable to the liquid flow rate through the fuel delivery line during most of a fueling operation. A vapor impulsion booster boosts the vapor flow rate above the liquid flow rate early in a fueling operation.
