汽油濾芯到底應該更換一次？
Should the gasoline filter element be replaced once?
汽濾更換周期比較長，一般3-5萬公里更換一次，具體需要根據你的保養手冊或者實際使用情況。同時，還要根據平時使用的汽油質量情況而定。如果燃料雜質含量大，汽油濾清器堵塞的機率就會大大增加，更換周期就要適當縮短。另外需要注意的是，如果汽車出現以下現象，又排除了其他原因，可能你的汽油濾清器過臟或堵塞，是時候該換了。
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.急加速無力，且汽車大載荷運行時動力下降明顯:汽油濾芯輕度堵塞，一般會使發動機供油不暢，導致發動機功率會有所下降。
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.怠速時發動機抖動:汽油濾芯中度堵塞，不僅不使汽車動力變差，還會使汽車怠速時出現發動機抖動現象。
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.啟動困難或直接啟動不著車:汽油濾清器嚴重堵塞時，汽車會出現啟動困難甚至無法啟動的現象。像有時候需要打火2-5次才能打著。
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.
當然，以上故障現象都是需要在排除其他故障后，才能判斷出是燃油濾清器的問題，因為由燃油濾清器問題引起的故障現象和燃油系統故障(如噴油嘴堵塞等)大同小異。
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).
提醒車友們，多數發動機上裝的都是一次性不可拆洗式的紙質濾芯汽油濾清器，在更換汽油濾芯的時候，一定要選購好的濾芯，并按照廠家的指導規程來進行操作。
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.
如果使用劣質的濾芯，不但材質差，而且過濾效果差，長時間在汽油內浸泡，濾芯本身會有過濾層脫落，堵塞油路，造成燃油系統壓力異常，直接導致發動機動力不足或燃燒不充分，后續的結果會讓你“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"!
