The present disclosure relates to a vehicle fuel system including a turbocharger having a compressor disposed on an intake line of an engine. The compressor selectively compresses intake air supplied to the engine. The fuel system has a canister configured to capture fuel vapor discharged from a fuel tank; and a purge control valve configured to open or close the purge line according to the pressure of the intake line. The fuel system has a check valve disposed on the purge line that prevents fluid from moving from the intake line to the canister. The fuel system has a controller that performs control such that, when damage to the check valve is detected during driving of the vehicle, the purge control valve operates in a closed mode to prevent intake air in the intake line from being introduced into the fuel tank.

    本公开涉及一种车辆燃料系统,该燃料系统包括涡轮增压器,该涡轮增压器具有设置在发动机的进气管路上的压缩机。压缩机选择性地压缩供应到发动机的进气。燃料系统具有罐,被配置为捕获从燃料箱排放的燃料蒸汽;以及净化控制阀,被配置为根据进气管路的压力打开或关闭净化管路。燃料系统具有设置在净化管路上的止回阀,该止回阀阻止流体从进气管路移动到罐。燃料系统具有控制器,该控制器执行控制,使得在车辆的驾驶期间,当检测到止回阀的损坏时,净化控制阀以关闭模式操作以防止进气管路中的进气被引入到燃料箱中。
