汽車費油的原因很多，但大體可以分為兩類，一是由于車子本身原因，二是由于駕駛員的駕駛習(xí)慣。下面
濟南奧迪汽車保養(yǎng)人員來講講車子本身原因。
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.
胎壓過低
Low tire pressure
小時候騎自行車都遇到過爆胎或漏氣的情況吧，這時候再騎的話，蹬起來老費勁了，因為胎壓過低會造成輪胎與公路的接觸面積增加，車輪的滾動阻力增加。所以，為了避免增加油耗，胎壓一定要合理，目前家用車的胎壓一般維持在2.3kPa，根據(jù)實際用車情況不同可以小幅度上下調(diào)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.
機油問題
Oil problem
有人會發(fā)現(xiàn)車子剛保養(yǎng)完油耗會有小幅度的上升，很可能與更換的機油粘度有關(guān)，機油粘度越高，發(fā)動機越費油。此外，機油加多了也會對油耗有影響，所以更換機油一定按照要求更換合適的機油，而且別貪，機油不是越多越好。
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.
發(fā)動機積碳
Engine carbon deposit
積碳的產(chǎn)生是不可避免的，再貴的車也有積碳。由于油品、個人駕駛習(xí)慣等問題發(fā)動機在運轉(zhuǎn)的過程中產(chǎn)生積碳，積碳造成燃燒不充分，車子自然而然費油。市面上有很多清潔產(chǎn)品，效果褒貶不一。當(dāng)然，你也可以去4S店專門做一個清積碳大保健。
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.
火花塞損壞
Spark plug damaged
火花塞的作用是點燃氣缸內(nèi)的可燃氣體，火花塞的點火功率下降會直接導(dǎo)致燃油燃燒不充分，如果火花塞壞掉不工作則會出現(xiàn)發(fā)動機缺缸的情況。
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.
活性炭罐破損
The activated carbon canister is damaged
汽油具有高揮發(fā)性，所以活性炭罐的目的是為了吸附收集氣化的汽油，在常溫的情況下，燃油箱充滿著汽油蒸汽，為了抑制它無故浪費，這個時候通過活性炭罐的吸附儲存，在汽車啟動的瞬間，再噴出燃燒。所以如果活性炭罐失效，也會造成燃油消耗增加。
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.fmghkd.cn Consult!
