Venting systems and methods are provided for a fuel system of an engine. In at least one example, the fuel system includes a fuel tank connected to a vapor recovery canister via a main conduit. The venting system includes an electrically actuated vent control valve, a plurality of sensors, and a control unit coupled to the sensors and to the electrically actuated vent control valve. The vent control valve is configured for being installed in the main conduit to thereby enable selectively opening or closing fluid communication between the fuel tank and the vapor recovery canister. The plurality of sensors are configured for providing data indicative of conditions relating to the tank. The control unit is configured for operating the electrically actuated vent control valve to open or close the fluid communication according to first predetermined criteria, wherein the first predetermined criteria include minimizing risk of liquid carry over (LCO) from the fuel tank to the vapor recovery canister. A corresponding method is also provided.

    一种用于发动机燃料系统的排放系统及方法。在至少一示例中,燃料系统包括经由主导管连接到蒸气回收罐的油箱。排放系统包括电启动的排放控制阀、多个传感器和连接到传感器和电启动的排放控制阀的控制单元。排放控制阀配置为安装在主导道,从而能选择地打开或关闭油箱及蒸气回收罐之间的流体连通。多个传感器配置用于提供指示与油箱相关的状况数据。控制单元配置用于根据第一预定标准操作电启动的排放控制阀,以打开或关闭流体连通,第一预定标准包括最小化从油箱到蒸气回收罐的液体携带(LCO)的风险,以及一种相应的方法。
