What is the problem with a lot of blue smoke coming out of the oil filler

Hello, this is a series of gas, the oil is burned, the gap between the engine piston ring and the cylinder is too large, and part of the high-pressure gas passes through the gap to the crankcase, and a large amount of gas will come out of the oil port.

Buy a car, use a car, maintain a car, repair a car, and listen to Chen Gong talk about cars.

1. Reasons. 1.The flammable mixture is too thick.

2.There is too much oil in the engine fuel. 3.

Poor piston ring or crankshaft oil seal sealing. 4.There is moisture in the fuel.

5.Bad spark plug 6The air filter is too dirty.

2. Fault diagnosis and elimination.

1.For the inspection and diagnosis of excessive concentration of combustible mixtures, the carburetor and air filter should be checked.

2.The blend does not compare with the blend of the oil, or the wrong grade of oil is used. If the oil mixture contains too much oil or the oil quality is poor, the oil of the flammable mixture cannot be completely burned, resulting in black smoke.

The above phenomenon can also occur in two-stroke engines with separate lubrication and oil pump misalignment and excessive oil supply. At this time, the oil pump should be checked and adjusted according to the regulations to ensure that the lubricating oil is supplied proportionally at different throttle openings.

3.Excessive wear or breakage in a four-stroke engine, as well as too much oil in the crankcase, can cause oil to string into the combustion chamber and cause excessive oil in the mixture. If the crankshaft oil seal of a two-stroke engine is broken, it will also cause the oil from the transmission to string into the crankcase and enter the combustion chamber with the mixture.

4.One of the reasons for the mixing of water in the fuel is that the fuel in the fuel tank itself contains water, so the fuel tank should be cleaned and the fuel should be replaced. Another reason is that the cylinder gasket of the water-cooled engine is broken, and cold water enters the cylinder.

If, in the absence of leakage, the water in the tank is consumed too quickly, and the exhaust smoke from the exhaust pipe is slightly white, this is mostly the reason and the head gasket should be replaced.

Black smoke from gasoline engines is rare, black smoke is mainly not completely burned fuel in the combustion chamber, in the case of high temperature and lack of oxygen, diesel can not be completely and fully combusted, so decomposition and aggregation to form soot, it is a small diameter of the aggregate.

Because this aggregate reacts much slower than gasified fuel, due to the high temperature and anoxic environment of the combustion chamber, it cannot be fully burned again and is discharged through the exhaust pipe, so black smoke is presented.

The direct consequence of this phenomenon is that the fuel consumption of diesel engines is very high, the power is reduced, and at the same time, a large amount of carbon deposits exist in the piston and piston ring valves. In severe cases, the piston rings will be jammed, the valve seal is not tight, and the air leakage will be accelerated, and at the same time, it will also accelerate the wear of parts, thereby reducing the service life of the engine, so this aspect should be paid special attention.

Normal white smoke is because of the exhaust gas in the exhaust pipe discharge, when the temperature of these exhaust gases reaches a certain layer will condense into water droplets, if there is a large amount of white smoke, it may be that the piston of the engine is damaged, resulting in the burning of engine oil out of the thick white exhaust gas, or the gasoline contains too much water, and it may be caused by the damage to the gasket in the waterway.

Part of it is car oil vapor, and there is a high probability that part of it is water vapor. The temperature inside the car engine, the moisture that the gas in the car engine can hold. When the car oil cap is opened, the gas runs out, the temperature outside is low, and the working capacity of the gas to contain water is reduced due to the decrease in temperature, and a part of the water is saturated and precipitated in the form of water vapor.

Similar to everyone's winter exhalation of the aroma from the mouth, the basic principle is the same.

The solution is also very simpleAs long as the car buyer cultivates good travel habits. In the severe cold natural environment, heat the car for 3 to 5 minutes before traveling, so that the car engine can quickly reach the optimal operating temperature. If there is a standard, carry out more long-distance driving, so that the automobile engine can obtain sufficient heat engine, and the problem of increasing engine oil and automobile oil cap emulsion can certainly be solved.

Car buyers should also not forget to maintain and maintain the car engine regularly, so that they can better maintain the car engine.

The oil light is on: there is less oil in the car, in other words, the oil pressure is not reached, in other words, the sensor is false alarm. According to your description, the oil port of the car engine is smoking, that is generally less car oil, in this case, you should park immediately, and then fill the car oil to the standard part, and then start the shift, if the car oil lamp is not on, the engine sound is normal, then everything can be driven normally, but in the whole process of driving, you should pay attention to the oil lamp anytime and anywhere.

All in all, the quality of today's vehicles is relatively good, the key depends on how you maintain it, how you travel, if the maintenance is appropriate, pay more attention to travel, and the car engine basically does not need to be repaired.

Automobile oil cap smoke means that the automobile engine piston is not very well matched or has long been invalid, causes the engine combustion chamber and the crankcase ventilation communication, so the occurrence of opening the automobile oil cap smoke, generally this will be with the exhaust pipe "black smoke" (engine burns oil) situation, therefore this automobile engine to disassemble the engine piston again, cylinder head gasket, cylinder when necessary also to replace, to ensure the airtightness of cylinder engine combustion chamber, to avoid automobile oil channeling.

This white smoke is actually the result of the evaporation of water from the oil. The temperature inside the engine is high, and the gas in the engine can hold more water molecules, and when the oil cap is opened, the gas escapes and comes into contact with cold air, which will form white smoke.

Most likely, it is water vapor. When the water vapor inside is cooled, it turns into small droplets. Because the temperature difference between the inside and outside is relatively large, this phenomenon will occur.

It may be that the temperature is not high enough, so some of it cannot be fully burned before it turns white, or it may be because there is stagnant water in it.

That's because it's too hot, and there's a certain amount of oil evaporating, so that's why it's happening.

Summary. Dear, hello, I am happy to answer for you: the engine oil leaked the problem of smoke under the engine

It doesn't matter much, if the oil is dry, you don't have to worry about this will not catch fire, at most it will only smoke, when the temperature of the engine exhaust pipe rises, the oil will smoke, and the oil will be burned clean in ten minutes at most, which is okay and does not need to be treated.

The oil is leaking, and the smoke under the engine is a big problem.

Dear, hello, I am happy to answer for you: the oil leaks the problem of smoke under the engine Answer: It doesn't matter much, the oil is dry and you don't have to worry about this will not catch fire, at most it is just smoke, when the temperature of the engine exhaust pipe rises, the oil smokes, and the oil will be burned clean in ten minutes at most, which is okay and does not need to be treated.

If it is due to the oil leakage on the surface of the engine during maintenance, the blue smoke generated by the evaporation of the surface oil due to the high temperature after the engine is started will not affect the engine. However, if it is oil leaking when the engine is running, it should be repaired in time.

When it comes to the phenomenon of smoke coming from the oil filling port, everyone has different opinions. Some people think that everything is normal, while others think that something abnormal has been discovered and must be investigated.

In fact, it is normal for the oil cap to open and smoke, and it is necessary to understand that the temperature of the car engine is very high, and the oil will definitely be destroyed in the car engine to produce a part of the oil vapor. Therefore, if the oil cap is opened without completely cooling the car, smoke will occur. However, if it is accompanied by an unpleasant burning smell, it is likely that the engine oil has been burned, and it is necessary to go to the car repair shop as soon as possible to carry out an inspection.

Can you drive with a burning smell of smoke in front of the car?

If there is smoke in front of the car and there is a burning smell, it is best not to drive again. After all, the direct impact of burning engine oil is particularly large, not only the amount of oil will continue to decrease, but also will cause the oil to ignite insufficiently, and in the long run, it will accumulate a lot of carbon deposits at the cylinder and cylinder wall, resulting in car idling and shaking, abnormal noise, acceleration fatigue and sluggishness, and black smoke from exhaust gas. Secondly, it will accelerate the destruction of the vehicle's oxygen sensor, resulting in the blockage of the three-way catalytic converter, or even direct damage.

Engine oil plays a role in lubrication, heat dissipation, sealing, and cleaning in the engine and is very important for the engine.

During engine operation, a part of the oil turns into steam and enters the crankcase through the piston rings, which is separated by the oil-air separator in the crankcase's forced ventilation system.

If the oil-air separator fails, the engine burns oil.

The oil needs to be changed regularly. If it is not changed for a long time, the performance of the oil will deteriorate, resulting in abnormal wear and tear of the engine.

Each time you change the oil, you need to change the oil filter together. When buying an oil filter, you need to choose a product from a big brand. Some low-quality filters do not filter well and can damage the engine with long-term use.

When buying an oil, you should choose the type of oil that is suitable for your car's engine.
