What is the reason for the reduction of engine oil Master, please advise

It's ......This ......It doesn't seem to be a non-class problem between computers and networks, right?

Hehe! It doesn't hurt either. Usually, engine oil is only used on machinery, usually on internal combustion engines. There are three main reasons for the reduction of engine oil:

1.The body is not well sealed and there is a leak.

2.Severe wear of mechanical components, such as cylinders of internal combustion engines, pistons and piston rings, leads to the so-called "burning of engine oil".

3.Due to the wear of the cylinder of the internal combustion engine, the piston and the piston ring are seriously worn, the combustion gas is channeled into the gearbox, the pressure in the gearbox increases, the exhaust valve is opened, and the gas and oil are sprayed out from the exhaust port, which promotes the loss of oil spray.

It is inevitable that the oil that plays a lubricating role between the piston and the cylinder wall in the motor will participate in combustion, as long as it does not exceed one liter within 5,000 kilometers, it is normal oil consumption, and vice versa.

Burning engine oil is basically caused by piston ring stagnation. As long as there is no serious strain on the cylinder wall, it does not need to be overhauled. Changing the maintenance of high-viscosity engine oil is only an expedient measure to treat the symptoms rather than the root cause, and it will do more harm than good.

The solution to burning the oil.

In the habitual thinking of car enthusiasts, they always think that burning engine oil should be overhauled, so that they not only have to bear high maintenance costs, but also bear the unpredictable risks and depreciation losses brought about by the overhaul. Destroy the airtightness and precision of the engine. And there is a possibility that the engine oil will burn again after tens of thousands of kilometers, so overhauling the engine is not sustainable.

Now the no-dismantling technology has been very mature and gradually accepted by the majority of car owners. In particular, the non-destructive repair products containing PNF patented technology have completely gotten rid of the technical shackles of burning engine oil and having to go to the auto repair shop for overhaul, without removing a screw, repairing and releasing the piston ring stuck engine oil while driving, with remarkable results.

For example, in a maintenance cycle, the amount of oil consumed from the upper limit of the dipstick to the lowest limit is the abnormal consumption of oil, and the abnormal consumption of oil is common for the following reasons;

1. Oil leakage from the sealing parts of the engine crankshaft front and rear oil seals, valve chamber cover gaskets, etc., is usually more common in old models that are about 5-6 years old or more, and the treatment method is to replace the relevant oil seals and gaskets.

2. The forced ventilation valve of the crankcase is abnormal, the internal pressure of the crankcase is too high, and the oil and gas enter the engine through the intake pipe for combustion, or the piston ring has excessive carbon deposition and hairpin, resulting in part of the oil film on the cylinder wall entering the combustion chamber for combustion.

3. Wear of engine cylinders, pistons and piston rings may lead to abnormal oil reduction.

If there is no oil leakage on the surface of the engine seal during the maintenance cycle of the vehicle, and there is abnormal oil consumption, it is recommended to go to the repair shop or 4S shop for a detailed inspection.

2. After refueling, do you check the fuel level after starting and then stopping? Some high-end cars are electronic dipsticks, which can be seen on the dashboard, and some masters don't know how to look at them? Is there any work to do this step?

Some of the car oil grid is relatively large, check the oil level before departure, check the oil level after departure, check the oil level is less, generally speaking, our factory requires the master to stop after the departure, and then check whether the oil level is normal. Prevent this from happening.

3. Is there any water seepage or leakage in the oil pan screw and oil grid? There are quite a few cars that have this phenomenon.

4. Whether there is water seepage or leakage in other places.

5. Engine burns oil? Generally speaking, it won't be so fast, right? It's only a day less? It is estimated that the first four scenarios are more likely.

There are the following situations: 1. The oil on the wall of the piston sports cylinder liner participates in combustion. 2. The piston ring sealing problem, a small amount of oil is burned out of the cylinder by the piston ring.

3. The oil filtration function of the respirator, part of the oil becomes oil and gas leaked by the respirator. 4. Engine sealing problems, oil leakage.

Because the oil will be sent to the cylinder for lubrication and cooling, although there is an oil ring on the piston to prevent the oil from entering the combustion chamber, it is not absolute, as the wear gap of the ring increases, there will always be some into the combustion chamber and burned.

I didn't find any burning oil, I couldn't smell the exhaust at all, there was no problem with the power, and the sound of the engine was normal.

During the use of the vehicle, the owner regularly checks the oil content to ensure that the oil is sufficient, so that the engine parts can have a good lubricating effect. So what's the deal with the lack of oil?

The main reason for the decrease in oil is caused by improper adjustment of the fit between the components, such as too large the gap between the piston and the cylinder, too large the gap between the intake valve stem and the valve guide, and poor ventilation of the crankcase. When the engine is working, it is normal for the oil volume to decrease due to high temperature and heat dissipation, but if the oil consumption is abnormal, it is necessary to investigate the cause of the fault in time.

In addition, in the process of using the vehicle, we must choose high-quality engine oil, if the quality of the engine oil is not up to standard, it will lead to the thinning of the oil film in the process of use, infiltrating into the combustion chamber to participate in combustion, and high-quality engine oil can delay the occurrence of this phenomenon. It is recommended that car owners regularly clean the oil circuit of the fuel to avoid the accumulation of serious carbon deposits.

<> "There may be several reasons for the reduction of motor oil in automobiles:

1.Oil spills. Oil pipes or oil pans may leak due to aging or damage, resulting in a decrease in oil. Oil leaks can also be caused by aging or damaged oil seals, cracks or wear in the oil pump or oil pan.

2.Engine wear. Engine wear can lead to an increase in oil consumption. If the car has a long driving range, the engine may experience wear and tear, which can lead to an increase in oil consumption.

3.The oil circuit is blocked. If the oil line or oil filter is contaminated or blocked, the flow of oil may be reduced, resulting in a decrease in oil.

4.The dipstick reading is inaccurate. Inaccurate dipstick readings can cause the oil to look like it's gone, but it's not actually going to be a decrease.

5.Incorrect oil grade. If the incorrect oil grade is used, the consumption of oil may increase, resulting in a decrease in oil.

When a decrease in oil is found, it should be checked and the problem should be solved in time. If the oil reduction causes the engine to fail, it can lead to more serious problems or even damage to the engine. Therefore, it is advisable to check the oil level regularly and change the oil and oil filter as recommended by the car manufacturer to ensure the proper operation of the engine.

The following are the main reasons for the sudden decrease in automobile oil: 1. Tumbling into the combustion chamber and combustion: when the gap between the piston ring and the cylinder wall is too large, the sealing condition of the combustion chamber becomes poor, and the engine oil will flow into the combustion chamber for consumption.

Aging or malfunctioning valve seals can also allow excess oil to flow into the combustion chamber and be consumed. 2. Oil leakage: the oil will be continuously circulated inside the engine to lubricate the parts of each part, in order to prevent the oil from seeping out of the engine, the parts between the engine and the outside of the engine will have gaskets or oil seals to isolate the oil, and the oil will flow to the surface of the engine to form oil stains after the aging of these gaskets or oil seals.
