          寶馬保養后油耗反而增加了怎么回事?

          來源:http://www.webloomafrica.com/ 日期:2024-03-14 發布人:創始人

          有的車主有疑問,按理說汽車保養后,車輛工況應該更好了,油耗應該會降低啊,為什么很多時候油耗不降反增呢?而且是同一個人駕駛,路況也沒啥變化。下面分幾種情況簡單回答一下這個問題。

          Some car owners have doubts. In theory, after car maintenance, the vehicle's working conditions should improve and fuel consumption should decrease. Why does fuel consumption often increase instead of decreasing? And it's the same person driving, and the road conditions haven't changed much. Below, I will briefly answer this question in several situations.

          1、油耗微增,一般百增加0.5L左右,不超過1L,原因有:

          1. Fuel consumption has slightly increased, generally increasing by about 0.5L per 100 kilometers, not exceeding 1L, due to the following reasons:

          2、機油粘度變大:在排除用機油的情況下,就算一模一樣的機油,新換上的肯定比跑了1萬的機油粘度要高,這樣形成的阻力自然更大一些,相同路況相同駕駛的情況下,油耗自然會更多一些。這種情況一般跑個大幾百就會慢慢消失。

          2. The viscosity of the engine oil becomes larger: if the engine oil is not used, even if the engine oil is the same, the viscosity of the new engine oil must be higher than that of the engine oil that has run 10000 kilometers. This will naturally cause greater resistance. Under the same road conditions and driving conditions, the fuel consumption will naturally be higher. This situation usually disappears gradually after running a few hundred kilometers.

          3、更換了剎車片:更換新剎車片之后,摩擦間隙相對較小,相對來說剎車時形成的阻力相對較大,從而會造成油耗微增,過了剎車片的磨合期就好了,一般300左右。

          3. Replacing brake pads: After replacing the new brake pads, the friction clearance is relatively small, and the resistance formed during braking is relatively large, which can cause a slight increase in fuel consumption. After the brake pad's break in period, it will be better, usually around 300 kilometers.

          4、稍微加多了機油:機油過多,機油中的曲軸轉起來就需要更多的能量,這不就增加了發動機的負荷了嗎,油耗自然會有所增加。

          4. Slightly adding more oil: If there is too much oil, the crankshaft in the oil needs more energy to rotate, which increases the engine's load and naturally leads to an increase in fuel consumption.

          5、油耗增加挺多,原因有:

          5. The fuel consumption has increased significantly due to the following reasons:

          6、如果更換了火花塞/噴油嘴,可能安裝有問題或使用了錯誤型號:比如安裝沒按標準扭矩來上緊,容易產生漏氣,致使缸壓變小,發動機無力,從而增加油耗。

          6. If the spark plug/fuel injector is replaced, there may be installation problems or the wrong model may be used: for example, if the installation is not tightened according to the standard torque, it is easy to cause air leakage, resulting in a decrease in cylinder pressure, engine weakness, and increased fuel consumption.

          7、如果有清理積碳:

          7. If there is a cleaning of carbon deposits:

          有些情況跑著跑著就會正常,因為行車電腦需要一定的里程來適應清理后的工況。不過,如果清理積碳后,由于清理下來的積碳導致三元堵塞,也會導致油耗上升。

          In some cases, running will be normal because the driving computer needs a certain mileage to adapt to the cleaned working conditions. However, if the carbon deposits are cleaned up and cause ternary blockage, it can also lead to an increase in fuel consumption.

          8、清洗了節氣門:

          8. Cleaned the throttle valve:

          這種情況一般是清洗后忘記了匹配,去匹配后油耗就會正常。

          This situation is usually caused by forgetting to match after cleaning, and after matching, the fuel consumption will be normal.

          9、平均油耗被清零:保養時候平均油耗被重置,這樣重新計算油耗,如果你不是馬上走的是高速,重新計算的油耗前期都會很虛高,跑個幾百就會下來了。

          9. Average fuel consumption is reset to zero: During maintenance, the average fuel consumption is reset, so the fuel consumption is recalculated. If you are not driving on the highway immediately, the recalculated fuel consumption will be very high in the early stage, and it will come down after running a few hundred kilometers.

          保養后油耗增加的原因差不多就這些了,遇見了大家可以比照來看,應該能比較快速的找到問題所在。

          The reasons for the increase in fuel consumption after maintenance are basically these. If you encounter them, you can compare them and quickly find the problem.
