Burning oil means that the oil enters the combustion chamber of the engine and participates in combustion together with the mixture. If the vehicle burns engine oil, the oxygen sensor will be damaged too quickly, resulting in increased carbon deposition in the combustion chamber, unstable idle speed, weak acceleration, increased fuel consumption, excessive exhaust emissions and other adverse consequences. The most serious result of burning engine oil will be insufficient lubrication of the engine, resulting in irreparable damage or scrapping of the engine.

燒機油看起來事小，嚴重時又會造成很大的安全隱患，因此要學會一些分辯的常識。

Burning engine oil seems to be a small matter, but when it is serious, it will cause great safety hazards. Therefore, we should learn some common sense of discrimination.

一、如何判斷自己的車輛有燒機油現象?

1、 How to judge if your vehicle is burning oil?

發動機燒機油的表象是什么?

What is the appearance of engine oil burning?

1、涼車燒機油。

1. Cool the car and burn the engine oil.

每天早晨次著車時，后排氣管會有比較濃的藍色煙霧排出，但過一段時間藍色煙霧就會消失，之后一般不會再有類似的情況發生。

In the morning, the smoke in the back of the car will disappear after the first time.

2、加速時燒機油。

2. Burn oil when accelerating.

在車輛行駛時猛踩油門或原地著車時猛踩油門時，從排氣管會排出大量藍煙，嚴重時可以從排氣管一側的反光鏡中看見藍色煙霧。

When you step on the accelerator when you are driving or when you are landing, a lot of blue smoke will be emitted from the exhaust pipe. If it is serious, you can see the blue smoke in the reflector on one side of the exhaust pipe.

燒機油對車輛的危害非常大，車輛氧傳感器過快損壞，導致燃燒室的積碳增加、怠速不穩、加速無力、油耗上升、尾氣排放超標等等嚴重后果。更嚴重時會因發動機潤滑不足，使引擎造成難以修復的損傷甚至報廢，造成維修成本大幅升高，甚至存在事故隱患。

Burning engine oil is very harmful to the vehicle. The oxygen sensor of the vehicle is damaged too quickly, which leads to the increase of carbon deposition in the combustion chamber, unstable idle speed, weak acceleration, increased fuel consumption, excessive exhaust emissions and other serious consequences. In the most serious cases, the engine will cause irreparable damage or even scrapping due to insufficient lubrication of the engine, resulting in a substantial increase in maintenance costs and even the existence of accident risks.

如何判斷發動機是否存在燒機油現象?

How to judge whether there is oil burning in the engine?

1、眼觀：燒機油的主要表現是行車時尾部排出藍色尾氣，這表示過多的機油進入燃燒室參與燃燒。

1. Visual observation: the main performance of burning engine oil is the blue tail gas discharged from the tail when driving, which means that too much oil enters the combustion chamber to participate in combustion.

具體的操作有以下幾點：

The specific operations are as follows:

(1)清晨冷車啟動后，查看排氣管是否會冒藍煙。

(1) After the cold car starts in the morning, check whether the exhaust pipe will emit blue smoke.

在清晨冷車時進行檢測排氣管是否冒藍煙是因為發動機長時間不運轉時，機油就會在重力的作用下通過氣門油封的間隙流入汽缸。一啟動發動機，汽缸內的機油就會在高溫高壓的作用下燃燒，產生大量藍色煙霧。

When the car is cold in the morning, the exhaust pipe emits blue smoke because when the engine is not running for a long time, the oil will flow into the cylinder through the clearance of the valve oil seal under the action of gravity. Once the engine is started, the engine oil in the cylinder will burn under the action of high temperature and high pressure, producing a large amount of blue smoke.

(2)在車輛行駛中或者原地猛踩油門時，排氣管是否有大量藍煙冒出。

(2) Whether there is a large amount of blue smoke coming out of the exhaust pipe when the vehicle is driving or pressing the accelerator violently.

這種檢測方法主要是檢查發動機活塞環與汽缸壁之間是否存在密封不嚴。車輛在急加速時，活塞環上下運動頻率加快，汽缸壁上殘存的潤滑油容易被活塞環帶入燃燒室，導致“燒機油”。

This detection method is mainly to check whether the sealing between engine piston ring and cylinder wall is not tight. When the vehicle accelerates rapidly, the piston ring moves up and down quickly, and the remaining lubricating oil on the cylinder wall is easy to be carried into the combustion chamber by the piston ring, resulting in "oil burning".

(3)除了排氣管外，也要觀察機油口是否會不時冒藍煙。

(3) In addition to the exhaust pipe, also observe whether the oil port will emit blue smoke from time to time.

如果在任何情況下，排氣管都有藍煙冒出，而且機油口不時冒出藍煙，說明發動機的磨損情況已相當嚴重，車輛需要及時進行大修，否則會造成嚴重的事故隱患

If under any circumstances, blue smoke is emitted from the exhaust pipe and blue smoke is emitted from the oil port from time to time, it indicates that the wear of the engine is quite serious, and the vehicle needs to be overhauled in time, otherwise it will cause serious accident potential
