汽油滤芯到底应该更换一次？
Should the gasoline filter element be replaced once?
汽滤更换周期比较长，一般3-5万公里更换一次，具体需要根据你的保养手册或者实际使用情况。同时，还要根据平时使用的汽油质量情况而定。如果燃料杂质含量大，汽油滤清器堵塞的机率就会大大增加，更换周期就要适当缩短。另外需要注意的是，如果汽车出现以下现象，又排除了其他原因，可能你的汽油滤清器过脏或堵塞，是时候该换了。
The replacement cycle of steam filter is relatively long. Generally, it is replaced once every 30000-50000 km. The specific needs depend on your maintenance manual or actual use. At the same time, it should be determined according to the quality of gasoline used at ordinary times. If the content of fuel impurities is large, the probability of gasoline filter blockage will be greatly increased, and the replacement cycle should be appropriately shortened. In addition, it should be noted that if the following phenomena occur in the car and other reasons are eliminated, your gasoline filter may be too dirty or blocked. It's time to change it.
1.急加速无力，且汽车大载荷运行时动力下降明显:汽油滤芯轻度堵塞，一般会使发动机供油不畅，导致发动机功率会有所下降。
1. The rapid acceleration is weak, and the power drop is obvious when the vehicle is running under heavy load: the gasoline filter element is slightly blocked, which will generally make the engine oil supply blocked, resulting in a decrease in engine power.
2.怠速时发动机抖动:汽油滤芯中度堵塞，不仅不使汽车动力变差，还会使汽车怠速时出现发动机抖动现象。
2. Engine jitter at idle speed: the gasoline filter element is moderately blocked, which not only does not deteriorate the vehicle power, but also makes the engine jitter when the vehicle is idling.
3.启动困难或直接启动不着车:汽油滤清器严重堵塞时，汽车会出现启动困难甚至无法启动的现象。像有时候需要打火2-5次才能打着。
3. Difficult to start or unable to start the car directly: when the gasoline filter is seriously blocked, the car will be difficult to start or even unable to start. Like sometimes it takes 2-5 times to fire.
当然，以上故障现象都是需要在排除其他故障后，才能判断出是燃油滤清器的问题，因为由燃油滤清器问题引起的故障现象和燃油系统故障(如喷油嘴堵塞等)大同小异。
Of course, the above fault phenomena can only be judged to be the problem of the fuel filter after other faults are eliminated, because the fault phenomena caused by the problem of the fuel filter are similar to those of the fuel system (such as blocked fuel injection nozzles).
提醒车友们，多数发动机上装的都是一次性不可拆洗式的纸质滤芯汽油滤清器，在更换汽油滤芯的时候，一定要选购好的滤芯，并按照厂家的指导规程来进行操作。
Remind motorists that most engines are equipped with disposable non removable paper filter elements and gasoline filters. When replacing the gasoline filter element, be sure to buy a good filter element and operate according to the manufacturer's guidelines.
如果使用劣质的滤芯，不但材质差，而且过滤效果差，长时间在汽油内浸泡，滤芯本身会有过滤层脱落，堵塞油路，造成燃油系统压力异常，直接导致发动机动力不足或燃烧不充分，后续的结果会让你“意想不到”!
If the inferior filter element is used, not only the material is poor, but also the filtering effect is poor. If you soak in gasoline for a long time, the filter element itself will fall off and block the oil circuit, resulting in abnormal pressure in the fuel system, which will directly lead to insufficient engine power or insufficient combustion. The subsequent results will make you "unexpected"!
