问:当汽车关闭气体气味。没有泄露或2010宝马328 i

听起来你可能泄漏油箱通风系统中可能导致烟雾逃脱燃料箱。这可以发生在通风管在油箱泄漏或者当一个叫做清洗阀泄漏。这可能是与你EVAP排放系统和一个叫做分流阀电磁阀。EVAP系统防止油箱的燃油蒸汽泄漏到大气中。EVAP系统收集和临时存储燃油蒸汽活性碳罐。活性碳罐充满了活性炭颗粒能够吸收燃料蒸气。发动机运行时,罐和燃烧的燃料气体清除引擎。排气控制阀(电磁)控制外部空气流的活性碳罐。这不是正常工作时,你可能会体验到加油站关闭过早导致花费很长的时间来填满你的油箱。这是由于存在多余的燃料蒸汽清洗电磁阀不正常工作时释放蒸汽。 The gas pumps at the fuel station have automatic sensors on them (for safety reasons) that shut off automatically when too much fuel vapor is present. I would recommend having an expert from Your Mechanic come to your home to take a look at your car to诊断你EVAP清洗电磁阀。
