汽车费油的原因很多，但大体可以分为两类，一是由于车子本身原因，二是由于驾驶员的驾驶习惯。下面
济南奥迪汽车保养人员来讲讲车子本身原因。
There are many reasons for car fuel consumption, but they can be generally divided into two categories: one is due to the car itself, and the other is due to the driver's driving habits. Next, the Jinan Audi car maintenance personnel will talk about the car itself.
胎压过低
Low tire pressure
小时候骑自行车都遇到过爆胎或漏气的情况吧，这时候再骑的话，蹬起来老费劲了，因为胎压过低会造成轮胎与公路的接触面积增加，车轮的滚动阻力增加。所以，为了避免增加油耗，胎压一定要合理，目前家用车的胎压一般维持在2.3kPa，根据实际用车情况不同可以小幅度上下调整。
When I was a child, I used to ride a bicycle with a flat tire or air leak. It would be hard to pedal at this time, because too low tire pressure would increase the contact area between the tire and the road, and increase the rolling resistance of the wheel. Therefore, in order to avoid increasing fuel consumption, the tire pressure must be reasonable. At present, the tire pressure of household vehicles is generally maintained at 2.3kPa, which can be adjusted up and down slightly according to the actual situation.
机油问题
Oil problem
有人会发现车子刚保养完油耗会有小幅度的上升，很可能与更换的机油粘度有关，机油粘度越高，发动机越费油。此外，机油加多了也会对油耗有影响，所以更换机油一定按照要求更换合适的机油，而且别贪，机油不是越多越好。
Some people will find that the fuel consumption of the car will increase slightly just after maintenance, which is probably related to the viscosity of the oil replaced. The higher the oil viscosity, the more fuel the engine uses. In addition, adding more oil will also affect the fuel consumption, so you must change the oil according to the requirements. Don't be greedy. The more oil, the better.
发动机积碳
Engine carbon deposit
积碳的产生是不可避免的，再贵的车也有积碳。由于油品、个人驾驶习惯等问题发动机在运转的过程中产生积碳，积碳造成燃烧不充分，车子自然而然费油。市面上有很多清洁产品，效果褒贬不一。当然，你也可以去4S店专门做一个清积碳大保健。
Carbon deposition is inevitable. No matter how expensive the car is, there is carbon deposition. Due to oil products, personal driving habits and other problems, the engine generates carbon deposits during operation, which causes insufficient combustion, and the car naturally consumes fuel. There are many cleaning products on the market, and the effects are mixed. Of course, you can also go to the 4S store to do a special carbon cleaning health care.
火花塞损坏
Spark plug damaged
火花塞的作用是点燃气缸内的可燃气体，火花塞的点火功率下降会直接导致燃油燃烧不充分，如果火花塞坏掉不工作则会出现发动机缺缸的情况。
The function of the spark plug is to ignite the combustible gas in the cylinder. The reduction of the ignition power of the spark plug will directly lead to insufficient fuel combustion. If the spark plug is broken and does not work, the engine will be out of cylinder.
活性炭罐破损
The activated carbon canister is damaged
汽油具有高挥发性，所以活性炭罐的目的是为了吸附收集气化的汽油，在常温的情况下，燃油箱充满着汽油蒸汽，为了抑制它无故浪费，这个时候通过活性炭罐的吸附储存，在汽车启动的瞬间，再喷出燃烧。所以如果活性炭罐失效，也会造成燃油消耗增加。
Gasoline is highly volatile, so the purpose of the activated carbon canister is to adsorb and collect the gasified gasoline. At room temperature, the fuel tank is full of gasoline vapor. In order to prevent it from being wasted for no reason, the activated carbon canister is used to adsorb and store the gasoline and then eject it for combustion at the moment when the car starts. Therefore, if the activated carbon canister fails, the fuel consumption will also increase.
The above are some common cases of car fuel consumption. You can continue to add. Come to our website for more information http://www.lutongqixiu.com Consult!
