The relationship between turbocharger failure and oil burning

Smoke from the exhaust pipe: blue smoke is burning engine oil; Black smoke is the incomplete combustion of fuel; White smoke is boiling water!

There are many reasons to boil water: a small amount of water that enters along the intake air on a rainy day; In winter, the cold air in the cylinder is the cause of the boiling water in the cylinder. Just think of the white smoke that pulls from the back of all the cars in winter!

On top of that, diesel fuel and water can be easily dissolved together. So it's obvious that your car is boiling water, and it's probably caused by this!

Many petrol stations have just put two large truckloads of diesel fuel into underground storage tanks, and if you add that first shot of oil, you have a good chance of winning the lottery! Because transporters often mix it with water!

Recommendations:1Open the drain valve under the diesel filter and press the hand oil pump to achieve the purpose of draining water!

2.Replace the diesel filter and the symptoms should be able to get **!

3.Change the diesel filter regularly and drain the water!

4.Go to the repair yard to check the ignition timing, and don't get it yourself!

Finally, some advice on turbocharging:

The Qingling turbocharged engine model is 4JB1 T C, and its turbocharging device uses lubricating oil supplied by the engine. Therefore, you must use "supercharged diesel engine oil" for maintenance to ensure that the supercharger can get sufficient lubricating oil supply. And after each start, keep idling for about 2 minutes to allow the engine to fully supply the oil to the supercharger!

Otherwise, the supercharger impeller can reach 7,500 rpm due to a little refueling, and it is very easy to form dry grinding without lubricating oil. You should also keep idling for about 2 minutes before extinguishing the car, so as to avoid the sudden loss of lubricating oil supply, cooling and increased wear of the high-speed supercharger impeller caused by engine stopping!

Why does a turbocharger burn oil? When the rotor in the exhaust gas turbocharging is working at a high speed of more than 100,000 revolutions in a high-temperature working environment of more than 600 degrees, the oil lubricating the rotor and the air filter element that filters the air will be incorrectly selected or not maintained in time, which will lead to the turbocharging and burning the oil!

The main reason for burning engine oil is that the turbocharging technology is not up to par, the pressure and temperature of the engine at work are greatly increased, so the engine life will be shorter than the engine with the same displacement without supercharging, and the increase in pressure directly leads to the increase in temperature The oil becomes very dilute at high temperature, and at the same time, it is easy to vaporize through the cylinder wall under the action of high temperature pressure into the cylinder combustion chamber, and burn off with the fuel.

It is very likely that the valve cover gasket is not well sealed, there is a gap between the cylinder and the piston, the turbocharger is damaged, the quality of the oil is not very good, etc., it may also be the cause of the German car, the German car has a problem, that is, it is easy to burn the oil, usually it may be because the engine is not maintained in time, the engine has carbon deposits, and the spark plug is blocked.

There are two ways to solve the problem of burning engine oil

Overhaul. PNF restoratives.

Benefits of this one:In the case of overhaul, the cost is very high, the vehicle depreciates quickly, and the later run-in is also very troublesome. First of all, you need to find out the reason for your burning oil, oil circuit blockage, carbon deposits, piston ring stagnation can be repaired with PNF repair agent, there are many riders who have successfully repaired through PNF repair agent, you can refer to it.

The pressure and temperature of the engine are greatly increased when it is working, the turbocharging technology is not up to par, the valve cover gasket is poorly sealed, the turbocharger is damaged, and inferior oil is used.

This is because there is a problem with the cylinder and piston, which may be caused by a large gap, or by temperature, or by poor sealing.

At present, there are more turbocharging and piston ring anomalies. It is best to measure the cylinder pressure. If there is nothing wrong with the cylinder pressure. That might be taking into account the turbocharging aspect.

Reasons for burning engine oil: long-term unclean oil circuit, untimely replacement of antifreeze, and too long oil service cycle.

The harm of burning engine oil: it will continue to generate greater carbon deposits, which will seriously pull the cylinder. The three-way catalytic converter is completely damaged in the poor combustion exhaust gas,,, and the continuous life-sustaining oil will eventually cause the engine to burst the cylinder.

The three points of the car that burn the engine oil will inevitably occupy one point, and the most important point is the high temperature caused by the oil circuit not being effectively cleaned.

Causes of piston ring seizure.

The oil used for the stuck piston ring will be caused by the oil scraping not clean and remaining on the cylinder wall, causing the oil to participate in combustion and burn the oil. Among them, the cylinder wall will be seriously worn due to the delay in processing, and the engine will have to be disassembled.

In fact, the treatment principle of piston ring stagnation should start from the oil circuit, the reason for the stagnation is the beginning of the oil circuit, the oil bearing temperature is 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 be exhausted 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 5000 kilometers of a liter of oil, at this time, the working conditions of other cylinders will also begin to be bad, and soon the 4 cylinders will be stuck. It becomes a liter of engine 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.

At present, the effective method is to use the oil burning oil repair agent of the original solution of the company to clean the oil circuit and the cylinder, and release the carbon sludge stuck in the piston ring by penetrating into the piston ring. For most of the vehicles where the piston ring does not have a counterpart, the stagnation can be completed as long as it is repaired in this way, and the oil wiping function can be restored to improve the phenomenon of burning oil.

My colleague's car is also burning engine oil, the exhaust valve is fine, planning to release the piston ring, directly using the Si Youpu stock liquid type of burning engine oil repair agent, after 5 times in a row, from the previous 1200 kilometers plus a liter of engine oil to the current 6000 kilometers without adding oil, the price comparison, overhaul is the most such an effect. The cost is only one-tenth of that of an overhaul, and the residual value of the car is maintained.

"High temperatures" are the biggest test for turbocharger operation. When the turbine is running, the first contact is the high-temperature exhaust gas (the first heat source) discharged from the engine, which pushes the turbine wheel and drives the compressor wheel on the other side to run synchronously. The rotation speed of the entire blade axle is often 120,000-160,000rpm.

Therefore, the heat generated by the high-speed rotation of the turboshaft is very impressive (the second heat source), and the temperature of the air compressed by the compressor impeller (the third heat source) is the most severe high temperature burden of the turbocharger. The turbocharger becomes a self-contained operating system with high-temperature components. So "heat dissipation" is very important for turbochargers.

There are special oil channels (heat dissipation and lubrication) inside the turbine body, and many of them are designed with organic oil channels and water channels at the same time, which reduce the temperature of the supercharger through dual heat dissipation of oil cooling and water cooling.

Due to the high temperature, the oil seal will age quickly, the sealing performance will decline, the oil will enter the engine with the air flow for combustion, and the turbine due to the high speed, the fine impurities in the air will also cause the impeller to lose its roundness, and the oil seal will also be poorly sealed, which will cause the oil to burn.

Turbocharging tends to cause oil burning, and it is not simply due to the manufacturing process. Here's why:

1.There is more clearance between the cylinder and the piston.

When the turbine is running, the gap between the cylinder and the piston of the engine is reduced due to the rapid increase in temperature due to the thermal expansion and contraction of the metal. Therefore, at the beginning of the design of turbocharged engines, compared with naturally aspirated engines, it is necessary to reserve a wider gap between the cylinder and the piston, so that when the car starts running, more oil and gas will escape into the combustion chamber and form engine oil.

Solution: It is recommended to replace or repair the cylinder and piston.

2.Process issues with air-oil separators.

With the current technology, the oil-gas separator is not completely separated, and a part of the oil and gas and the mixture enter the combustion chamber for combustion. Turbocharged engines, on the other hand, have higher requirements for the material and design of the oil-air separator, so it is relatively easier for turbocharged engines to burn oil.

Solution: It is recommended to check the problem of gasoline dismantling and dismantling in time.

3.The rotor is lubricated and cooled by oil.

A turbocharger is mainly composed of a pump wheel and a turbine. The pump wheel and turbine are connected by a rotor, which rotates at a high speed. Therefore, turbochargers generally use full floating bearings, which are cooled by oil lubrication, which also causes excessive oil consumption.

Solution: It is recommended to check the rotor and lubricating oil for the problem. Millions of car purchase subsidies.

During the design and manufacture of the engine, some gaps are reserved between the various components, between the piston and the cylinder, so as not to cause the parts to be crushed and damaged after high temperature expansion. When the engine starts, when the water temperature and engine temperature are still relatively low, a small part of the engine oil will flow into the combustion chamber through these gaps, which will also cause the situation of burning engine oil.

Similarly, in order to reduce friction and ensure the high-speed operation of the turbine, the oil seal of the foot pin should not be too tight, so a small amount of oil will enter the turbine at both ends through the oil seal, and then enter the intake pipe and exhaust pipe, so it will cause the oil to burn.

The main reason for burning engine oil

There is a problem with the fittings, the wastegas valve, the valve seal, the cylinder is pulled in the cylinder, and the cylinder pressure is insufficient.

If the oil circuit is not cleaned for a long time, the antifreeze is not replaced in time, the oil life cycle is too long, the piston ring is stuck, and the more common situation is that the piston ring is stuck.

What is piston ring seizure

The stagnation is the land crack pin from the oil circuit, the oil temperature is 110 degrees, and the oil circuit is not clean for a long time caused by the high temperature, so that the oil is at a temperature of 120 degrees or higher for a long time, so that the oil will be exhausted in advance, the small hole of the oil ring is very small, the oil inside will be baked dry and scabbed for a long time, a source of no cylinder stagnation is 5000 kilometers of a liter of oil, at this time the working conditions of other cylinders will also begin to be bad, and soon the 4 cylinders are stuck, It becomes a liter of engine oil for 1000 kilometers or even hundreds of kilometers.

Turbocharger Oil Burning Symptoms If the turbocharger burns oil, the engine's oil consumption will be abnormal, and the turbocharger needs to be repaired or replaced with a new one. Engine oil is something that every car owner will come into contact with, and engine oil is very important for the engine of a car.

Engine oil not only plays a lubricating role in the engine, but also plays a role in cleaning, sealing, buffering, rust prevention, and heat dissipation.

When the engine is running, the oil will form a layer of oil film on the surface of the various parts in the engine, which can prevent the friction caused by the direct contact of the various parts in the engine.

If the various parts within the engine come into direct contact and cause friction, it will increase the wear and tear of the engine and can also cause the engine to overheat.

The performance of the engine oil will be reduced after a long period of use, so the engine oil needs to be changed regularly.

If you don't change the oil for a long time, it will also exacerbate the wear and tear of the engine.

It is recommended that you change the oil regularly when you use the car, and change the oil filter element every time you change the oil.

The oil filter is used to filter the oil, and if there is no oil filter, the oil will become dirty after a period of use.

When buying engine oil and oil filter cartridges, be sure to buy them from regular channels, and be sure to choose the best products from big brands.

When maintaining, be sure to go to a professional organization to find a professional for maintenance.

Turbocharger burns oil symptoms.

If the turbocharger burns oil, it will cause the engine to consume more oil and will also cause the turbocharger to lack lubrication. When this happens, it should be repaired immediately. Turbocharging technology has been used in car engines for a long time.

Turbocharging technology can increase the air intake of the engine without increasing the engine displacement.

The engine is fueled by a mixture of fuel and air, and if the amount of air intake is increased and the amount of fuel injected is correspondingly increased, it is equivalent to the amount of fuel in the cylinder of the engine is supercharged.

The turbocharger is composed of two parts, one is the compression turbine and the other is the exhaust turbine.

The exhaust turbine and compression turbine are coaxially connected, and the exhaust turbine is connected to the exhaust manifold of the engine, and the compression turbine is connected to the intake manifold of the engine.

When the engine reaches a certain speed, the exhaust has enough energy to push the exhaust turbine to rotate, and the compression turbine of the engine can also rotate at this time.

When the compression turbine rotates, it compresses and delivers air into the cylinders of the engine.

Some cars use a supercharging system in their engines, which works differently than turbocharging. (Photo by Q&A: Q&A called the beast) @2019
