  • Patent number: 10501309
    Abstract: A fuel vapor recovery control system includes a controller, a recovery electrical motor, a fuel vapor switching valve, a fuel vapor recovery pump, a fuel tank, a fueling pump, a fuel gun, and a temperature sensor connected in sequence. A fueling flowmeter is arranged on a fueling pipeline, in signal connection with the controller, the recovery electrical motor and the fuel vapor recovery pump in sequence. The temperature sensor is in signal connection with the controller for controling the recovery electrical motor and the fuel vapor recovery pump by temperature signals. The fuel vapor recovery control system includes a fuel vapor flowmeter for measuring the fuel vapor recovery amount, in signal connection with the controller for controling the recovery electrical motor and the fuel vapor recovery pump by fuel vapor recovery amount signals. The fuel vapor recovery ratio is between 1-1.4. A method of adopting the system is provided herein.
