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.

烧机油看起来事小，严重时又会造成很大的隐患，因此要学会一些分辩的常识。

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、如何判断自己的车辆有烧机油现象?

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

发动机烧机油的表象是什么?

What is the appearance of engine oil burning?

1、凉车烧机油。

1. Cool the car and burn the engine oil.

每天早晨次着车时，后排气管会有比较浓的蓝色烟雾排出，但过一段时间蓝色烟雾就会消失，之后一般不会再有类似的情况发生。

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

2、加速时烧机油。

2. Burn oil when accelerating.

在车辆行驶时猛踩油门或原地着车时猛踩油门时，从排气管会排出大量蓝烟，严重时可以从排气管一侧的反光镜中看见蓝色烟雾。

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.

烧机油对车辆的危害非常大，车辆氧传感器过快损坏，导致燃烧室的积碳增加、怠速不稳、加速无力、油耗上升、尾气排放超标等等严重后果。更严重时会因发动机润滑不足，使引擎造成难以修复的损伤甚报废，造成维修成本大幅升高，甚存在事故隐患。

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.

如何判断发动机是否存在烧机油现象?

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

1、眼观：烧机油的主要表现是行车时尾部排出蓝色尾气，这表示过多的机油进入燃烧室参与燃烧。

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.

具体的操作有以下几点：

The specific operations are as follows:

(1)清晨冷车启动后，查看排气管是否会冒蓝烟。

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

在清晨冷车时进行检测排气管是否冒蓝烟是因为发动机长时间不运转时，机油就会在重力的作用下通过气门油封的间隙流入汽缸。一启动发动机，汽缸内的机油就会在高温高压的作用下燃烧，产生大量蓝色烟雾。

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)在车辆行驶中或者原地猛踩油门时，排气管是否有大量蓝烟冒出。

(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.

这种检测方法主要是检查发动机活塞环与汽缸壁之间是否存在密封不严。车辆在急加速时，活塞环上下运动频率加快，汽缸壁上残存的润滑油容易被活塞环带入燃烧室，导致“烧机油”。

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)除了排气管外，也要观察机油口是否会不时冒蓝烟。

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

如果在任何情况下，排气管都有蓝烟冒出，而且机油口不时冒出蓝烟，说明发动机的磨损情况已相当严重，车辆需要及时进行大修，否则会造成严重的事故隐患

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
