我們列出了7種汽車經常出現的小問題，采訪了多位老駕以及具有多年維修改裝汽車經驗的技師，一下是我們整理的7個汽車常見的故障原因以及保養方式給到大家：
We have listed the common problems of 7 kinds of cars and interviewed a number of old drivers and technicians with many years of experience in repairing and refitting cars. Here are 7 common fault causes and maintenance methods of cars:
汽車啟動時，發動機點不著火
When the car starts, the engine does not ignite
原因：發動機的啟動是靠電瓶的電流推動火花塞點火完成的，造成發動機突然點不起火可能會有以下兩個原因，首先很可能是由于電瓶生銹或者電瓶滴漏所造成，其次就是下雨天發動機火花塞受潮引起的。
Cause: the engine is started by the spark plug ignition driven by the current of the battery. There may be the following two reasons for the sudden ignition failure of the engine. Firstly, it is likely to be caused by the rust or leakage of the battery, and secondly, it is caused by the moisture of the engine spark plug in rainy days.
保養方法：每一兩個月要查看電瓶內的電瓶液是否充足。觀察時如果液面位于上下2條刻線之間則認為合適。同時也應該檢查各槽的液面差。如果液面不足，可以擰下蓄電池上面的蓋子，倒入蒸餾水補足液面。隨后還要檢查蓄電池的接線端子，使用鐵刷子刷除接線端子上的積污。如果接線卡箍嚴重污損，可以用砂紙順著內壁擦動，磨掉污物。如果是火花塞受潮，可將其拿出，用打火機進行烘烤，以便盡快地使其上面的水分蒸發。
Maintenance method: check whether the battery liquid in the battery is sufficient every two months. It is considered appropriate if the liquid level is between the upper and lower scribed lines during observation. At the same time, the liquid level difference of each tank should also be checked. If the liquid level is insufficient, unscrew the cover on the battery and pour distilled water to make up the liquid level. Then check the terminal of the battery and remove the dirt on the terminal with an iron brush. If the wiring clamp is seriously damaged, wipe it along the inner wall with sandpaper to remove the dirt. If the spark plug is damp, take it out and bake it with a lighter, so as to evaporate the water on it as soon as possible.
汽車排氣噪音增加廢氣排放量增加超標
Automobile exhaust noise increases and exhaust emission exceeds the standard
原因：出現這種原因，可能是由于發動機的廢氣經高溫發生氧化作用，導致排氣系統泄漏。
Cause: this may be due to the oxidation of engine exhaust gas at high temperature, resulting in leakage of exhaust system.
保養方法：定期檢查排氣系統的管路、接口處(特別是消音器等)是否被廢氣腐蝕，接口墊有沒有被沖壞。若發現排氣系統泄漏應及時到4S店進行修理或更換泄漏的部件。每年檢查一次不僅可以保證排氣系統正常運轉，更重要的是減少尾氣中有害物質對環境的污染。
Maintenance method: regularly check whether the pipelines and interfaces (especially silencers) of the exhaust system are corroded by waste gas and whether the interface pads are washed out. In case of leakage of the exhaust system, timely go to the 4S store for repair or replace the leaking parts. Checking once a year can not only ensure the normal operation of the exhaust system, but also reduce the environmental pollution caused by harmful substances in the tail gas.
汽車油耗莫名增加
Car fuel consumption increases inexplicably
原因：油耗增加的原因很多。但常見又容易被車主忽略的是對輪胎氣壓的檢查。輪胎胎壓不足不僅會導致行駛阻力增加，造成油耗上升，還會影響輪胎的使用壽命。
Reasons: there are many reasons for the increase of fuel consumption. But the common and easily ignored by car owners is the inspection of tire pressure. Insufficient tire pressure will not only increase driving resistance and fuel consumption, but also affect the service life of tires.
保養方法：在開車時，多留意一下各個車胎是否有氣，并定期檢查輪胎氣壓。當然切記不要忘記備胎的檢查，以免急需更換輪胎時，才發現備胎已經沒氣了。氣溫高時胎壓會比平時高一些，因此在冷天或陰涼處測量胎壓比較準確。時常輪胎每行駛1萬公里要互換位置，避免前后磨損程度相差太大。如果需要更換磨損嚴重的輪胎，兩個或4個一起更好，紋路相同的輪胎可以前后交叉更換。另外，折線花紋的輪胎有助于節省燃油。
Maintenance method: when driving, pay more attention to whether each tire is inflated, and check the tire pressure regularly. Of course, remember not to forget the inspection of the spare tire, so as not to find that the spare tire is out of gas when it is in urgent need of replacement. When the temperature is high, the tire pressure will be higher than usual, so it is more accurate to measure the tire pressure in cold days or in the shade. Often, the tires should be interchanged every 10000 km to avoid too much difference between the front and rear wear. If you need to replace severely worn tires, two or four tires together are better. Tires with the same grain can be replaced crosswise. In addition, broken line tires help to save fuel.
汽車發動機性能明顯下降伴隨油耗增加
The performance of automobile engine decreases obviously with the increase of fuel consumption
原因：這很可能是由于長時間未更換機油、機油濾清器、空氣濾清器和汽油濾清器造成了油料燃燒不充分、發動機積碳增多等問題引起的。
Cause: This is probably caused by insufficient fuel combustion and increased engine carbon deposition due to the long-term failure to change the oil, oil filter, air filter and gasoline filter.
保養方法：機油、機油濾清器，每行駛約5000公里就要更換一次，而空氣濾清器和汽油濾清器每行駛1萬公里時需要進行更換，否則空氣、燃油和機油中的雜質會造成零件磨損和堵塞油路，從而影響發動機正常運轉。
Maintenance method: the engine oil and oil filter shall be replaced every 5000 km, while the air filter and gasoline filter shall be replaced every 10000 km, otherwise the impurities in the air, fuel and oil will cause parts wear and block the oil circuit, thus affecting the normal operation of the engine.
汽車油泵損壞
Damage of automobile oil pump
原因：加油時的不合理行為有可能造成油泵損壞。
Cause: unreasonable behavior during refueling may cause damage to the oil pump.
保養方法：車主在給汽車加油時，盡量不要等燃油報警燈亮了再加油，這樣做是會縮短油泵的使用壽命，存油太少或燃油耗盡都可能會燒毀油泵。如果常行駛于市區且加油比較方便則不必一次加滿，因為這樣可能會導致油浮及傳感器失靈、油表失真并增加油耗，所以建議車主在燃油消耗差不多的時候就要加油。
Maintenance method: when the owner refuels the car, try not to wait until the fuel alarm light is on. This will shorten the service life of the oil pump, and the oil pump may be burned if there is too little fuel or the fuel is exhausted. If you often drive in the urban area and it is convenient to refuel, you do not need to top up at one time, because this may lead to oil floating, sensor failure, fuel gauge distortion and increase fuel consumption. Therefore, it is recommended that car owners refuel when the fuel consumption is almost the same.
蓄電池不穩定
Unstable battery
原因：電解液的非正常變化會影響蓄電池的性能和可靠性。
Cause: abnormal changes of electrolyte will affect the performance and reliability of battery.
保養方法：夏季行車，蓄電池會出現過充現象，電解液蒸發快，板易損壞。因此，需要經常檢查蓄電池的液面高度和電解液比重(電解液比重較冬季應小些)，要經常向蓄電池加注蒸餾水；冬季盡量避免蓄電池完全放電，并注意電解液是否凍結。
Maintenance method: when driving in summer, the battery will be overcharged, the electrolyte will evaporate quickly, and the plate is easy to be damaged. Therefore, it is necessary to frequently check the liquid level height of the battery and the specific gravity of electrolyte (the specific gravity of electrolyte should be smaller than that in winter), and always fill the battery with distilled water; Try to avoid complete discharge of the battery in winter, and pay attention to whether the electrolyte is frozen.
雨刮刮洗玻璃效果不佳
The effect of wiper cleaning glass is poor
原因：雨刮片出現破損，會造成刮洗的不干凈。
Cause: the wiper blade is damaged, which will cause unclean scraping.
保養方法：首先車主需要改正干刮的不良習慣，還是先噴點水再開雨刮為好，這樣有利于保護雨刮片。其次，雨刮有時候會發出咯咯的響聲，這個時候如果雨刮片是完整的，那么車主需要到4S店進行雨刮角度的校正。如果車輛長期停放，車主可以找泡沫條或者木條之類的小東西，墊在雨刮下，使雨刮片與擋風玻璃相互分離，這樣可以延長雨刮的使用壽命
Maintenance method: first of all, the owner needs to correct the bad habit of dry scraping. It's better to spray some water before turning on the wiper, which is conducive to protecting the wiper blade. Secondly, the wiper sometimes makes a clucking sound. At this time, if the wiper blade is complete, the owner needs to go to the 4S store to correct the wiper angle. If vehicles are parked for a long time, the owners can search for small items such as foam sticks or wooden sticks, and pad them under the rain to separate the wiper blades from the windshields, thus prolonging the service life of the wipers.
