Oil will always be consumed, how exactly do you tell if you are burning oil?

When the engine is running, the piston moves up and down in the cylinder at high speed, and the oil acts as a lubricant and protectant between the two.

In other words, when the engine is running, some oil will inevitably remain on the wall of the combustion chamber and be burned off. Vehicle driving for some time, the oil will reduce some, which is called "oil consumption".

First, why will burn oil

Is oil consumption the so-called oil burning? No, it depends on the degree of consumption, if too much oil into the cylinder, and with the mixture of gases involved in combustion, resulting in excessive oil consumption. This is called "oil burning".

Generally speaking, there are the following cases of abnormal oil ingress:

01

Valve oil seal

Valve oil seal is an important part to prevent oil leakage into the combustion chamber, but with the increase of the age of the car, the valve oil seal wear, aging, etc., will affect the sealing of the valve, so that the oil is easy to leak into the combustion chamber when the engine is running, the phenomenon of oil burning.

02

Excessive piston ring clearance

Older models, there will often be insufficient combustion of carbon adhering to the piston ring, if not cleaned up for a long time, it is likely to make the piston ring and the gap between the cylinder body to expand, resulting in oil into the combustion chamber, resulting in oil burning phenomenon, and even lead to engine "cylinder" phenomenon. So it is very important to clean up the engine carbon regularly, and it is also an effective way to prevent oil burning.

03

Too much oil

If the amount of oil added over the normal engine demand, the engine pressure is too high will make the excess oil into the combustion chamber.

Second, what is the harm of burning oil

Many people think that burning oil is costly, yes, burning oil is one of the most direct harm is costly, for a couple of thousand kilometers or so to burn a liter of car, at least one year extra consumption of about 1500 yuan of oil money, burning oil = burning money!

However, to focus on, in addition to burning money, there is another important issue, that is, excessive oil into the combustion chamber, it will be more likely to form carbon deposits, so that the emissions exceed the standard. At the same time the engine power, noise, fuel consumption and other aspects will also be affected.

Carbon deposits caused by oil burning can easily lead to piston ring se izing, and may also lead to accelerated wear of the piston and cylinder wall, resulting in poor piston sealing, laying the groundwork for the next step of oil burning and falling into a vicious cycle.

Serious cases will even appear cylinder pulling, engine scrap and other results. How about, hear this is not a shock; next came to the key question, how to know their car is not burning oil.

Third, how to determine the burning oil

01

Cold car oil burning

In the vehicle static a night or a longer period of time, to wait for the engine and other temperatures completely cooled down, this time with the car after the exhaust will be sprayed out of the thicker blue smoke. After a period of time blue smoke disappears, this situation is generally the vehicle engine oil burning signs.

The main reason should be due to the valve oil seal aging or broken, resulting in poor sealing effect, oil from the valve into the cylinder and caused.

This situation will not be too dangerous to go to the repair does not necessarily need a major repair, if the cylinder liner wear is not serious, generally only change the piston ring and valve oil seal and valve guide can be.

02

Oil burning during rapid acceleration

In the vehicle driving if the rapid acceleration or in situ when the car stepped on the gas pedal, the exhaust pipe discharges a large amount of blue smoke, the same is also a sign of the vehicle burning oil. At the same time, the vehicle will have weak acceleration power, increased fuel consumption and other phenomena.

The possible reason is that the cylinder wall and piston ring sealing effect is bad, generally do not need major repair.

03

Oil consumption is too fast

When the vehicle traffic computer prompts the oil quantity is insufficient, or in the maintenance of the vehicle is found to put out the amount of oil is relatively small, in the exclusion of oil leakage, then you can judge the car's engine appears to burn oil.

Generally speaking, the vehicle after the break-in period, the normal consumption of oil is about 1000 kilometers / 0.3 liters, if the consumption is greater than this value, then it means that the vehicle appears to burn oil. At this time, it must be sent for repair urgently to avoid more serious failures and damages.
