How do you know that there is diesel in the engine oil, and how to tell if the diesel engine burns e

The way to check that there is diesel in the engine oil is: suddenly find that the engine oil suddenly becomes more, and there is a diesel smell in it, that is, there is diesel in the engine oil.

When you usually check and maintain the engine oil, take out the oil dipstick, and when you find that the engine oil suddenly increases, and there is a diesel smell in it, it may be that the diesel oil is in the oil. In addition, drip the oil from the dipstick onto the oil test strip or paper towel if the oil spreads out quickly and the area is large.

And when the outer ring is lighter, it also indicates that diesel may be in the oil. At this time, it should be noted that once diesel fuel is added to the engine oil, it will lead to a decrease in the viscosity of the engine oil, and will affect the lubrication performance of the engine oil, accelerate the wear of engine parts, and it is easy to pull the cylinder and hold the tile, and it will also affect the power of the car.

It can be seen from these aspects:

1) The position of the oil on the dipstick will be elevated (if the amount is small, it may not be easy to observe) 2) Smell the smell, the smell of diesel is still easy to identify.

3) If the oil is dropped on the paper, it will be in the middle of the drop, or the color of the oil (generally black), if there are signs of wetting around it, it is diesel.

There are several reasons why diesel fuel enters the engine oil.

The fuel pump is damaged, and the diesel fuel enters the diesel pump (commonly known as the big pump) through the oil transfer pump, and then enters the oil pan along the oil lubricating the camshaft of the diesel pump.

Poor atomization of the injector or faulty valves, resulting in poor atomization or insufficient combustion, as the combustion diesel fuel enters the oil pan along the cylinder liner wall.

If you drip the oil in the water and spread it out immediately, there will be diesel in it, and if the oil does not disperse, there will be no diesel in it.

The most intuitive phenomenon of diesel oil entering the engine oil is that the oil becomes thinner and smells of diesel.

Check that if there is fuel mixed in the oil, the ignition point of the oil will drop!

Hello, the reasons for the diesel engine diesel entering the oil are: 1. The sealing ring of the plunger sleeve of the fuel injection pump is damaged; 2. The gap between the piston ring and the cylinder wall is too large or the cylinder pressure is too low; 3. Caused by the failure of the oil seal or the failure of the fuel injector. Diesel oil into the oil treatment method:

The oil needs to be changed in time to avoid affecting the performance of the engine and causing damage to the vehicle. Engine oil is the engine lubricating oil, which can lubricate and reduce wear, assist cooling and cooling, seal leakage, rust and corrosion, shock absorption and cushioning for the engine. Diesel is a light petroleum product that is a mixture of complex hydrocarbons and is often used as fuel for diesel engines.

Solution: 1. Need to stop for 5 to 10 seconds and then take out the dipstick to check the height of the oil level to see if it meets the requirements; 2. Regular replacement and regular maintenance; 3. When adding and cleaning engine oil with an oil bath filter, you should pay attention to the height of the oil level, and add it to the middle of the upper and lower engraved lines; 4. When the supercharger fails, it should be repaired or replaced in time.

Identification method of burning engine oil:

1. Cool car burning engine oil: When you get on the car for the first time every morning, there will be a relatively thick blue smoke exhaust from the rear exhaust pipe. After a while, the blue smoke disappears, and there is generally no similar situation on the day.

2. Burn engine oil when accelerating: When the driver slams on the accelerator or steps on the accelerator when the vehicle is moving, a large amount of blue smoke is discharged from the exhaust pipe, and when the driver slams the accelerator when the vehicle is driving, the driver can see the blue smoke from the reflector on the exhaust pipe side.

3. Fill the vehicle with the phenomenon of "burning engine oil" with engine oil, let the owner go to the maintenance station to weigh the oil filter after driving 1000 kilometers, and then fill up the engine oil, and then let the owner drive 1000 kilometers. Repeated 3 times, to obtain an average value, after the run-in period of normal oil consumption can generally reach 1000 kilometers liters, if the standard is exceeded, there is a situation of burning oil.

Precautionary measures for burning engine oil:

1. Use high-quality engine oil

Engine oil is very easy to corrode and age in a long-term high temperature state, resulting in the oil film becoming thinner, and it is easier to escape to the combustion chamber to participate in combustion, so the use of high-quality engine oil can greatly delay this phenomenon.

2. Pay attention to the cleanliness of the fuel circuit

Fuel in the combustion process is indispensable to produce carbon deposits, and carbon deposits are the root cause of some car failures, such as the aging of valve seals, piston wall clearance, etc., all have a direct or indirect relationship with the formation of carbon deposits, considering the relationship between domestic oil products, it is necessary to use high-quality engine oil and (PNF) fuel additives to achieve, which is also the key to achieve no dismantling and repair to solve the problem of burning engine oil.

The simplest way to judge: look at the exhaust gas when starting, if there is blue smoke, there must be a little engine oil.

Blue smoke is to burn engine oil, and the thicker the blue, the more oil is burned.

1.Burn the engine oil in the cold engine. Generally, the oil burning in the cold engine refers to the burning of the engine oil when it starts for the first time in the morning.

Judgment method: When the diesel engine is started for the first time every morning, there will be a relatively thick blue smoke exhaust from the rear exhaust pipe. After a period of time, the blue smoke disappears, and there is generally no similar situation on the day (if the previous situation has been in place for a long time, there may be blue smoke when the engine is stopped in place for a long time).

The same problem occurred the next morning, and otherwise there was no blue smoke. If this happens, it is a cold engine to burn oil.

Reason: Due to the long-term use of the valve seal, the valve seal is aging and seriously worn, and it has been unable to achieve a good sealing effect. When the diesel engine is not running for a long time, the oil will flow into the cylinder through the valve oil seal under the action of gravity.

When starting the diesel engine, the oil in the cylinder will burn under the action of high temperature and high pressure, producing a large amount of blue smoke. When the diesel engine heats up, the valve oil seal will be heated to make the sealing effect better, so the phenomenon of burning engine oil in the hot engine disappears.

2.Burn the oil when accelerating. Burning engine oil during acceleration means that when the diesel engine accelerates, blue smoke comes out of the exhaust pipe, but after running at a steady speed, the blue smoke disappears.

Judging method: when the driver slams on the accelerator or when the accelerator is slammed on the accelerator when the vehicle is running, a large amount of blue smoke is discharged from the exhaust pipe, and when the driver slams the accelerator when the vehicle is moving, the driver can see the blue smoke from the reflector on the exhaust pipe side.

Reason: Due to the poor sealing of the piston ring and the cylinder wall on the piston of the diesel engine, the oil directly escapes from the crankcase to the cylinder during rapid acceleration, resulting in the burning of the engine oil.

Summary. 1.When you usually check and maintain the engine oil, take out the oil dipstick, and when you find that the engine oil suddenly increases, and there is a diesel smell in it, it means that the engine oil has diesel in it; 2.

Drip the oil on the dipstick onto the oil test strip or paper towel, if the oil spreads quickly, the area is large, and the color of the outer ring is light, it means that diesel fuel has been added to the oil.

1.When checking and maintaining the engine oil, the oil dipstick is extracted, and when it is found that the engine oil suddenly becomes more, and there is a diesel smell in it, it means that the engine oil has entered the chai hall; 2.Drip the oil on the dipstick onto the oil test strip or paper towel, if the oil spreads quickly, the area is very large, and the color of the outer ring is light, it means that diesel fuel has been added to the oil.

I am a trailer truck Auman 510 horsepower, just now suddenly alarmed the oil pressure abnormal, now pull out the oil dipstick and feel that the oil seems to be more than Xi I suspect that the wheel is into the diesel Liqinghong noodles, if the oil is abnormal, there is generally diesel into it.

Personally, I feel that it spreads very quickly.

Dear you go to the repair shop to check it out.

I was on the highway and just wanted to ask if there was a possibility that the diesel was leaking in.

Diesel fuel may leak in. The gasket is broken.
