當遇到緊急事情用車時，因為受到油表的“欺騙”而誤事，難免會讓人氣急敗壞，下面
濟南奔馳汽車保養(yǎng)廠家簡單的聊一聊油表工作的原理。油表失靈主要的原因是油位傳感器惹的禍。通常，油表刻度不準確會出現(xiàn)以下幾種情況：
When using a car in an emergency, being deceived by the fuel gauge can inevitably lead to a loss of popularity. Below, Jinan Mercedes Benz automotive maintenance manufacturer briefly discusses the principle of fuel gauge operation. The main reason for the malfunction of the oil gauge is caused by the oil level sensor. Usually, inaccurate oil gauge scales can lead to the following situations:
癥狀一：油表刻度時快時慢
Symptom 1: The oil gauge scale is fast and slow
具體變現(xiàn)：油表刻度顯示時快時慢。
Specific realization: The oil gauge scale displays fast and slow.
分析：這種油表失靈的現(xiàn)象比較常見。一般情況下，在前半段很多車型的油表會下降得比較慢，而過了中間刻度之后，就會下降得比較快。這個主要是和用來反應(yīng)油量的油泵設(shè)計有關(guān)，它不能很均勻地反映汽油的消耗變化，畢竟這種勻速變化很難實現(xiàn)，也不容易通過維修更換配件來改變。
Analysis: This phenomenon of oil gauge malfunction is quite common. In general, in the first half of many car models, the fuel gauge will drop relatively slowly, and after passing the middle scale, it will drop relatively quickly. This is mainly related to the design of the oil pump used to reflect the fuel quantity, which cannot reflect the changes in gasoline consumption evenly. After all, this uniform change is difficult to achieve and cannot be easily changed through maintenance and replacement of accessories.
癥狀二：油表刻度突然下降到零
Symptom 2: The oil gauge scale suddenly drops to zero
具體表現(xiàn)：半路上明明看到尚余兩格，可是行駛了一段距離后竟然直接下降到零。
Specific performance: On the way, I saw that there were still two spaces left, but after driving for a distance, I actually dropped directly to zero.
分析：油表的指示幾乎完全取決于油位傳感器，所以油表指針其實只是油位傳感器的一種直觀的表現(xiàn)方式。出現(xiàn)這種問題，那就說明車輛的油位傳感器有問題。一般是由于油位傳感器出現(xiàn)污漬，需要及時清洗。由于汽油里邊含有很多的雜質(zhì)，而油位傳感器一直浸泡在里邊，時間長了就會被污染，直接影響到指示的準確性。要是車輛已經(jīng)使用了5年以上，出現(xiàn)這種油表指示不準的情況，就很可能是油位傳感器發(fā)生了物理磨損，無法繼續(xù)正常工作。
Analysis: The indication of the oil gauge almost entirely depends on the oil level sensor, so the oil gauge pointer is actually just an intuitive representation of the oil level sensor. If this problem occurs, it indicates that there is a problem with the vehicle's oil level sensor. Usually, the oil level sensor is stained and needs to be cleaned in a timely manner. Due to the presence of many impurities in gasoline, the oil level sensor remains immersed in it for a long time and can become contaminated, directly affecting the accuracy of the indication. If the vehicle has been in use for more than 5 years and the oil gauge indication is inaccurate, it is likely that the oil level sensor has physical wear and cannot continue to function normally.
癥狀三：油表刻度上升
Symptom 3: The oil gauge scale rises
具體表現(xiàn)：油表的指針一直停留在某個位置上不動，有的甚行駛一段距離后，刻度顯示數(shù)值竟然有所上升。
Specific performance: The pointer of the fuel gauge remains stationary at a certain position, and some even drive a certain distance, and the displayed value on the scale actually increases.
分析：造成這種情況的原因主要是位于油位傳感器和浮子之間的連桿被卡住，使浮子不能正常地上下浮動，從而導致傳感器不會發(fā)生變化，所以油表指針就定格在某一個位置。
Analysis: The main reason for this situation is that the connecting rod between the oil level sensor and the float is stuck, preventing the float from floating up and down normally, resulting in no change in the sensor. Therefore, the oil gauge pointer is fixed at a certain position.
如何讓油表說真話？
How to make the fuel gauge tell the truth?
，盡量選擇油品較好的汽油。清潔的汽油會使油泵里面的雜質(zhì)較少，大大降低油表發(fā)生故障的概率。
Firstly, try to choose gasoline with better oil quality. Clean gasoline will reduce the impurities in the oil pump, greatly reducing the probability of oil gauge failure.
其次，定期清洗油路和油箱，車輛每隔行駛了5000km左右，使用油路清潔劑對汽車的油路進行一次清洗，同時每隔兩年就清洗一次油箱。由于長時間使用，油箱底部會出現(xiàn)很厚的一層淤泥，這也會間接影響到油表的準確性。多事項就來我們網(wǎng)站

Secondly, regularly clean the oil circuit and fuel tank. After the vehicle has driven for about 5000km, use an oil circuit cleaner to clean the vehicle's oil circuit, and also clean the fuel tank every two years. Due to prolonged use, a thick layer of sludge may appear at the bottom of the fuel tank, which indirectly affects the accuracy of the fuel gauge.
