  • 枫下家园 / 爱车一族 / 尾气的颜色
    我看到过有一段话关于尾气的颜色:if your car only smokes grayish/white smoke at start-up you may have leaking valve seals. 如此冒白烟的车应该是有毛病的,但路上许多的车都somke white smoke.哪位大虾能给点道点道。
    • 白烟是坏的,白雾通常是好的。有区别的。
      • question: how to tell smoke from fog?
        • 点只烟,冒的是烟;端杯开水,放到阳台上,冒的是雾。这还能分不清?
    • Great! Everyone is high hand.
