摘　　要：以某自主品牌车型A为例,就碳罐电磁阀噪声的传播途径进行了探索,找到了碳罐电磁阀噪声传递到乘客舱的主要途径。在不改变整个系统工作策略和标定的情况下,通过阻隔噪声的传播途径,大大减小了驾驶室内的噪声,达到良好效果。In cold environment, the working noise of Purge control valve transfers into the pas- senger compartment and disturbs driver and passengers. The noise transfer paths are researched. With- out changing the whole system working strategies and calibration, by blocking the transmission of noise, the noise in compartment is decreased remarkably.
