1 4t is the high oil consumption or the burning of engine oil

Causes of excessive oil consumption and how to prevent it.

The engine oil itself has a certain amount of consumption, and excessive consumption is the problem of burning engine oil. There are many factors that affect the burning of engine oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc., the following reasons will aggravate the oil consumption and cause the burning of engine oil, so that the vehicle appears:

1. Carbon deposition occurs in the combustion chamber, which makes the gas ring of the piston ring stuck, and the sealing is poor.

2. Oil sludge is generated in the lubrication system, and the oil sludge blocks the oil return hole of the oil ring and weakens the oil scraping performance.

3. Wear occurs between the piston and the cylinder wall.

4. The valve seal is corroded and aging, and the sealing performance fails.

In addition, cars now have crankcase ventilation systems (exhaust valves), which can also exacerbate oil consumption if there is a problem.

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 main reason for burning engine oilThe main reason for burning engine oil in French cars is two aspects, one is the problem of accessories, and the exhaust valve and valve cover of French cars are integrated, which is easy to affect the burning of engine oil. The second is that the oil circuit is not cleaned for a long time, the anti-rotten freeze is not replaced in time, the oil service life is too long, and the piston ring is stuck, and the more common situation is that the piston ring is stuck.

Causes of piston ring seizureStagnation starts from the oil circuit, the oil bears the temperature at 110 degrees, and the high temperature caused by the long-term unclean oil circuit makes the oil at a temperature of 120 degrees or higher for a long time, so that the oil will fail in advance, the small hole of the oil ring is very small, and the oil inside will be dried and scabbed for a long time, and a cylinder stuck is a liter of oil for 5000 kilometers, at this time, the working conditions of other cylinders will also begin to be bad, and soon the 4 cylinders are stuck, and it will become a liter of oil for 1000 kilometers or even hundreds of kilometers. Therefore, in order to solve the problem, we must start from the root oil circuit, which is the way to remove the root.

ResolutionThere are two ways to solve the problem of burning engine oil, one is overhaul, and the second is PNF repair agent. The cost of overhaul is very high, the vehicle depreciates quickly, and the later run-in is also very troublesome. First of all, you have to find out the reason for your burning oil, and some riders have used repair agents to repair the leakage, you can refer to it.

408 does not overhaul to solve the problem of burning engine oil.

Summary and solutions for burning engine oil for various models.

Preface: Volkswagen's cars burn a lot of engine oil, and there are also the phenomenon of burning engine oil, and the consumption is higher than the normal wear. There are pros and cons to burning engine oil or gasoline in cars.

But there are also a lot of cars that are naturally aspirated, such as the boss's Santana. However, after the wear and aging of the turbocharged engine, it may cause a relatively large consumption of engine oil. <>

But the turbocharger doesn't break down easily, and there is no problem with 100,000 kilometers of normal use. In daily life, many cars burn engine oil, domestic traffic jams, many traffic lights, vehicles go away or spine stop, the engine is easy to be in an idle state. Therefore, there is a lot of oil remaining in the cylinder mesh.

The Volkswagen burns engine oil mainly because of design defects, and the second-generation EA888 burns engine oil very powerfully. <>

Only cars with a high number of kilometers will have obvious oil burning, and serious oil burning is excessive wear, as long as the piston is replaced. And now many cars will burn the oil, but the German car burns the oil is more serious, Volkswagen's oil and gas separator is an officially recognized problem, in order to solve this problem, so it caused the engine to burn the oil, and the Volkswagen car oil and gas separator is easy to break, so the oil burning is more serious, pay attention to replacement. Moreover, Volkswagen's engine internal temperature is often high, especially for German BMWs, after the engine is turned off, the engine cooling fan will still be dissipating heat, and many owners think that it is a failure of the engine.

In fact, because the engine at high temperature is easy to cause internal oil loss, and the old high temperature aging of rubber parts, so it is easy to burn oil. Volkswagen's engine cylinder liners are made of a mesh design, so that when the piston is not oily, the oil can be hung for heat dissipation and lubrication, which will make the engine life longer. Therefore, the mesh design not only dissipates heat and lubricates, but also reduces friction.

But such a design is also very easy to consume oil.

Volkswagen burns engine oil mostly on EA888 engines, but EA211, EA211 burns engine oil very rarely.

Because the higher the displacement, the more the engine will burn up, which is directly proportional, and the engine will burn particularly fully.

Because this engine has some improvements, there is some oil burning, but it is still relatively energy-saving.

It is because other brands of Volkswagen use Qinmeng turbo engines, and then the amount of technology is also relatively high, and the engines at the same time are generally in some cars with a relatively small displacement, and they will not burn the first oil.

Volkswagen engine generally does not burn oil, the important reason for burning engine oil is that the oil quality is too poor, the poor quality of the engine can not be the engine when the engine is working to suck the dust in the air and the carbon deposits formed after combustion to clean off, if the carbon deposits are deposited in the engine, it will cause poor lubrication, aggravated wear, increased fuel consumption and decreased power. An engine is a machine that converts other forms of energy into mechanical energy, and it can be applied to both the power generation unit and the entire machine including the power plant. Take Volkswagen Sutar as an example:

It has a length, width and height of 4753mm, 1800mm and 1462mm, with a wheelbase of 2731mm and is equipped with a 7-speed dry dual-clutch transmission.

The concept of burning engine oil is that the car runs 1000 kilometers and the oil consumption exceeds the liters. The engine is worn to a certain extent, and the phenomenon of burning engine oil will occur. Volkswagen engines don't burn much oil.

How do I avoid burning engine oil?

1. Choose the right engine oil.

Proper use of engine oil can minimize engine oil burning, but many people have a misconception about engine oil, believing that the higher the engine oil price, the better. In fact, engine oil is like human blood, and the key to whether it is good or not is to see if the model is the right number. However, consumers have a very little knowledge about engine oil, first of all, the label of engine oil represents the viscosity, for example, the viscosity of the label 5w-40 is higher than that of 5w-30.

Compared with 5W-40, the low temperature fluidity of the former is better. Generally, 0W grade oil is more suitable for use in northern areas, and 5W is widely used.

2. Avoid intense driving in new cars.

Generally speaking, the current new car does not need to be deliberately run-in, but in the first 2000 kilometers, the engine, gearbox and other internal parts need a process to achieve a better fit. In this process, avoid rough driving behaviors such as floor oil and high rpm (over 4000 rpm). This avoids oil burning caused by poor coordination of engine internal parts.

Generally, oil is not burned. Strictly speaking, there is no precise answer to this question. Because there is no guarantee that there will be no exceptions.

Volkswagen's well-known oil-burning phenomenon is the second-generation EA888 engine. The latest third-generation EA888 engine has been improved a lot. Due to the addition of an oil wiper ring on the piston, the chance of burning oil can be reduced.

One thing to know here is that real oil combustion refers to the oil leaking into the engine and burning in the dismantling and simplification combustion chamber. The phenomenon is that the exhaust gas turns blue and smelly, and the exhaust pipe mouth is sticky, otherwise it is not burning engine oil.

At the beginning of the design of German car engines, they tend to make cars with better acceleration and handling, so they consume more oil. It can be understood in this way: one aspect is prominent, and the other aspect becomes a shortcoming.

Attached is a brief introduction to the public:

Volkswagen (German: Volkswagen) is an automobile manufacturing company, headquartered in Wolfsburg, Germany, and is the nuclear trouser of the Volkswagen Group, one of the world's four largest automobile manufacturers.

Volks means "citizen" in German, and Wagen means "car" in German. The full name means "national car", so it is often referred to as "Volkswagen". Taiwan Province is translated as fosscar, and Hong Kong, Macao, Taiwan and mainland China are translated as Volkswagen or Volkscar, which means "people's car".
