Warning: date() [function.date]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

最佳答案

热车抖的问题，主要可能是因为节气门、怠速马达、进气道、进气门和燃烧室积碳过多造成的。因为进气道的积碳、污垢过多，空气通道截面积发生变化，使得控制单元无法精确控制怠速进气量，造成混合气过浓或过稀，使燃烧不正常或起动后发动机抖动甚至无法起动情况的发生。同时还要对喷油嘴工作状态进行检查，喷油量的脉宽是否达标。
还要用内窥镜检查进气门和燃烧室的积碳是否过多。
建议您根据以上情况去4s店进行现场检查。
说明发动机磨损比较厉害了，机油在升温后流动性变好，无法起到填补磨损的细缝的作用。你要很注意了。
