From naturally aspirated to turbocharged, more and more car owners find that burning oil has become a common symptom of their cars, especially European and American models. So, what's the matter with burning engine oil? What effect does it have on your car? How can we deal with it correctly?

Oil burning is a "chronic disease"

If the car owner finds that the oil consumption of his car is too fast and other abnormalities during daily use, there are generally two situations: oil leakage or oil burning. The former can be solved as long as the cause of leakage is found, and the problem is generally small; However, if it is engine oil burning, the owner needs to pay attention to it, which may lead to serious consequences.

Oil burning means that oil enters the combustion chamber of the engine and participates in combustion with the mixture.

There are many reasons for oil burning.

First of all, some brands of vehicles use special process design inside the cylinder to strengthen the lubrication inside the cylinder, but at the same time, it will also make the engine increase the demand for oil. The piston will bring oil into the combustion chamber, resulting in excessive consumption of oil.

Secondly, the engine is strong and powerful, so the compression ratio is high and the operating temperature is relatively high. At this time, if the stability of the oil product is poor, it will evaporate at high temperature, which will also lead to oil consumption.

In addition, if there is too much carbon deposit, the wear between the piston and the cylinder wall will be aggravated, resulting in excessive clearance, and the oil entering the combustion chamber will also cause oil burning.

Common disease

In terms of working principle, oil burning has the following effects:

1. The combustion of engine oil will cause a large amount of carbon deposition in the combustion chamber. If it accumulates on the surface of spark plug electrode, it will affect the ignition intensity; Accumulation on the surface of fuel injector (direct injection in cylinder) will affect the atomization of fuel; Accumulation on the intake and exhaust valves may affect the sealing of the cylinder; Accumulation in the piston ring groove will have an impact on the piston ring, resulting in poor sealing of the combustion chamber and even cylinder pulling.

2. If there is too much carbon accumulation, it will also change the engine compression ratio, resulting in frequent engine knock and engine overhaul.

3. In addition, the exhaust gas after oil combustion will also make the oxygen sensor of the exhaust pipe invalid, which will make the control of the engine ECU deviate, affect the normal fuel supply, and in serious cases, affect the fuel consumption and power performance.

The engine oil exhaust gas will also pollute the three-way catalytic converter in the exhaust pipe, and serious burning of engine oil will cause the three-way catalytic converter "poisoning", leading to failure.

In a word, the harm of burning engine oil is still great, which needs the attention of car owners.

Early detection and early "treatment"

The light blue exhaust gas discharged from the exhaust pipe is the main characteristic of engine oil burning. Once you find that your car burns oil, you should deal with it in time to avoid causing more damage to your car.

Choose better quality gasoline. After the oxidation of additives in gasoline, colloidal substances will be formed. After entering the combustion chamber through the fuel injection nozzle for combustion, carbon deposits will be formed in the intake valve, piston top, piston ring groove, combustion chamber, spark plug and other parts, which will aggravate the aging of these parts and cause "oil burning". Therefore, selecting high-quality gasoline can reduce the phenomenon of "burning engine oil".

Avoid the engine running at high power for a long time. In daily use, the engine should be kept at high power for a long time as far as possible to reduce the chance of oil film fracture and avoid poor lubrication and dry grinding of rotating parts.

Select high-quality oil to prevent oil burning. The quality of oil directly affects the operation of the engine and plays a vital role in engine protection. High quality, stable and reliable oil can effectively reduce oil consumption, reduce engine wear, extend the oil change cycle and effectively prevent oil burning.
