What s the deal with the blue smoke from the engine but not the oil?

Poor engine combustion can also emit blue smoke. Inadequate combustion produces large amounts of carbon monoxide.

Carbon monoxide is burned during the emission process, and the exhaust gases are blue in the light. This is not due to the blue smoke caused by the oil entering the combustion chamber, so the oil is not consumed too quickly. However, the engine temperature will increase, the fuel consumption will increase, the engine performance will be weak, the operation will be unstable, the acceleration will be slow, and there will be abnormal noise.

The causes of poor combustion are complex, such as air cleaners.

Blockage, poor atomization of the nozzle, insufficient cylinder pressure due to valve leakage, insufficient cylinder pressure due to cylinder wear, timing errors, damaged advance device, spark plugs.

Damage, lack of cylinder, and system feedback errors lead to excessive fuel injection, low ambient temperature, and low machine temperature, resulting in poor combustion 、......It is recommended to send the factory to be solved from shallow to deep.

The blue smoke from the engine is basically burning the engine oil, and there are many reasons for this, roughly the following situations:

1. If the back pressure of the oil return oil circuit of the supercharger is too high, check whether the supercharger is leaking and whether the oil return pipe is blocked.

2. The exhaust gas valve is damaged, and the oil and gas cannot be separated, and it re-enters the combustion chamber for combustion.

3. The valve oil seal is aged, damaged or damaged, and the gap between the valve and the guide is too large.

Fourth, the oil exceeds the upper limit, so that the crankshaft throws the oil into the combustion chamber to participate in the combustion during high-speed operation.

5. The engine is severely worn, resulting in too large a gap between the piston and the cylinder wall, and the oil enters the combustion chamber through the gap.

Sixth, the piston ring is stuck, and the cylinder wall oil participates in the combustion. This is the reason why most cars burn engine oil.

The solution to burning engine oil.

Dismantling the engine for overhaul will 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.

With the progress of science and technology, the current dismantle-free repair technology has been very mature and has gradually been recognized and accepted by the majority of car owners. It not only saves the cost of car maintenance, but also protects the original car accessories. With exclusive patented technology, the company has universal non-destructive repair technology, which repairs and releases piston ring stuck oil while driving, and the effect is remarkable.

1) The piston ring is butt or held; (2) The gap between the piston and the cylinder wall is too large; The piston and cylinder are pulled out of the groove, and the end clearance, side clearance and backlash of the piston ring are too large; (3) The valve lifter and valve guide are seriously worn, and the gap increases; (4) The air filter is blocked (including the crankcase ventilation air filter), so that the cylinder has a vacuum; (5) The most effective way to diagnose the engine "burning oil" is to open the oil filler cap and observe whether the oil filler is poured out or smoked. If the oil filler is pouring out or smoking, the problem may be: too much gap between the piston and the cylinder wall; The cylinder is strained (grooved); The piston is encircled or counterparted; The piston ring of the newly assembled engine is reversed or the elastic force is too weak.

It's okay for the car engine to emit blue smoke, maybe it's a little more oil filling. It's okay to open for a while, don't be nervous, this should be normal. Reduce the oil a bit. It's okay if the engine is blue, as long as it doesn't emit black smoke.

It may be that the back pressure of the supercharger lubricating oil return is too high.

Check whether the supercharger is leaking oil, including the supercharger itself, and the supercharger oil return line. If the oil return line of the supercharger is blocked, resulting in poor oil lubrication and oil return, the oil will enter the intake line and enter the combustion chamber to burn and emit blue smoke.

The reason for the blue smoke is that too much oil is involved in combustion, which should be too much oil filled, and too much oil will be carried to the air filter through the crankcase snorkel (the crankcase snorkel is connected to the air filter) and burned by the air flow into the cylinder.

Basket smoke is a manifestation of burning engine oil, since it does not burn engine oil, then check whether the oil has entered the fuel tank from the oil pipe.

This is due to the fact that the engine may be new, and it is normal for the machine to be unusable.

This is a precursor to the burning of the machine.

Hello! How long does it take to get a car Most of the problems may be with the valve seals, check the valve seals** There is a problem.

The engine burns oil in two situations, one is that the oil enters the cylinder and burns it, and the other is that the oil is consumed in other places.

Automobile engine oil burning, refers to the oil used for lubrication, which flows to the combustion chamber and burns off together with the combustible mixture. As long as the situation is judged to burn the engine oil, the exhaust pipe emits blue smoke. The situation that you said about burning engine oil without emitting blue smoke can only mean that the car only burns engine oil slightly, so it can't be seen with the naked eye.

It is best to also check whether there is any oil leakage, and the occurrence of oil leakage will also reduce the engine oil.

What's the matter with the car burning engine oil and not being able to see the blue smoke?

1) The piston ring is butt or held;

(2) The gap between the piston and the cylinder wall is too large; The piston and cylinder are pulled out of the groove, and the end clearance, side clearance and backlash of the piston ring are too large;

(3) The valve lifter and valve guide are seriously worn, and the gap increases;

(4) The air filter is blocked (including the crankcase ventilation air filter), so that the cylinder has a vacuum;

5) The crankcase ventilation check valve is blocked or the check valve spring is broken.

It means that there is a slight oil leakage in the engine oil, and the idle state can not be seen, and there will be blue smoke only when accelerating at high speed, so it is usually not visible, and the reduction of the oil level is either oil leakage or burning engine oil, and it will not be for no reason.

The vehicle does not emit blue smoke, but the oil loss is very large, if it is determined that there is no oil leakage around the engine, the engine may really burn the oil, generally in the low load state can not see the engine exhaust blue smoke, only when some continuous uphill or vehicle load is relatively large, there may be a feeling.

The engine oil itself has a certain consumption, and excessive consumption leads to the problem of burning engine oil. Cars now have three-way catalytic converters, which can filter out some of the exhaust gases, and only when the oil consumption is relatively large, will there be blue smoke. There are many factors that affect the burning of engine oil, such as:

Fuel quality, driving conditions, driving habits, maintenance habits, etc., the above reasons will exacerbate oil consumption and cause oil burning. The following is the specific introduction: 1. Carbon deposition in the combustion chamber:

The air ring of the piston ring is stuck, and the sealing is poor. 2. Oil sludge generated in the lubrication system: The oil sludge blocks the oil return hole of the oil ring and weakens the oil scraping performance.

The engine burns the oil does not necessarily have to emit blue smoke, sometimes the oil is burned directly and the blue smoke is invisible, the place where the oil is burned is generally the oil leakage, the valve oil seal aging, the piston ring stagnation, the piston and the cylinder wall gap is too large and so on.

The engine oil itself has a certain amount of consumption, and excessive consumption is the problem of burning engine oil. Cars now have three-way catalytic converters, which can filter out part of the exhaust gases, and only when the oil consumption is relatively large, will there be blue smoke.

Burning engine oil is caused by the following factors, as long as the following problems are solved, burning engine oil can be solved.

There are many factors that affect the burning of engine oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc., the above reasons will aggravate the oil consumption and lead to the burning of engine oil, making the vehicle appear:

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.

As we all know, blue smoke from the exhaust pipe means that the engine burns oil, but only when the engine burns oil to a very serious level, the exhaust pipe will emit blue smoke, so the possibility of engine burning oil is not ruled out; In addition to the possible cause of burning engine oil, it may also be the phenomenon of oil leakage and oil leakage in the engine. Of course, whether it is engine oil burning or oil leakage and oil leakage, it is not something we can solve, and it is the right thing to go to the 4S shop for inspection and maintenance in time.

When the oil consumes a relatively large amount, it will emit blue smoke, and the gap between the valve and the duct may be too large. Hope it helps.

Hello! If this happens, it proves that your vehicle is burning engine oil at high speeds. Because when driving at high speeds, you may not be able to see if the exhaust pipe has a blue face, I hope it can help you.

Engine oil is generally white smoke, blue smoke is mainly due to some reason caused by a large amount of oil involved in combustion (such as excessive oil filling, etc.), if there is no white smoke or blue smoke in the case of oil reduction, it may be oil pan wire leakage or oil filter is not fastened oil leakage.

The engine burns engine oil but does not emit blue smoke, which may be due to the fact that the engine oil itself has a certain consumption. If you consume too much, you may have the problem of burning engine oil, and there will be no blue smoke.

It is normal to burn engine oil without blue smoke, and the amount of oil burned in this case is not large and can be ignored. If there is blue smoke, it means that the engine burns oil very seriously, and only overhaul can solve the problem.

Hello: 1, the problem of engine oil 2, the problem of the engine 3, the oil consumption is too small, only when the oil consumption is relatively large, there will be blue smoke.

The valve lifters and valve guides were heavily worn, the gap increased, and the air filters were clogged, including the crankcase ventilation air filters, causing a vacuum in the cylinders.

Not necessarily the design oil will emit blue smoke, you are now saying, well, how much oil is lost in an oil change cycle, this is the most important, if it is more than one and a half liters, it is worth the family car, and then it should be repaired, well, the key problem you have to analyze whether the valve oil seal is burned or the steel is less, if this is the case, you look at it is to say that if the valve oil seal has no solution, it can only be said to carry out decoupling maintenance, if it is a steel drum ring burning, you can add a repair agent to try.

If you find that the car's oil is always decreasing, but it does not emit blue smoke. It is likely that there is an oil leak, it may be that the oil seal is leaking, or the gasket is broken. Hope.

The engine burns oil but does not emit blue smoke, which means that the horsepower of your car is very large, and the fuel consumption is very large, which is normal.

The engine burns the engine oil but does not emit blue smoke, because the oil can still be burned off just after burning, so it does not emit blue smoke.

Generally speaking, blue smoke is a phenomenon of burning engine oil, and it is unlikely that your engine oil will have a slight oil leak elsewhere or that the temperature is high and the engine oil is consumed.

If your car engine burns oil but does not emit blue smoke, it means that your engine oil is not too bad, as long as you control the oil too much, then it will definitely emit blue smoke.

If the engine burns oil, what if it doesn't emit blue smoke? If it's possible, it's probably a bit of a problem with the frozen engine.

If only the public is normal!! Half of the vehicles of the general brand are high mileage wear and tear before burning the engine oil.

Under normal circumstances, I think that if the engine always appears but does not emit oil, it will smoke, in this case, now you can start it again, and after turning it on, you can make a product.

Summary. Hello, dear, if you smoke blue, it doesn't have to be burning engine oil, this is right, dear. If you emit blue smoke, you can't rule out the problem caused by the damage to the engine exhaust valve.

If the exhaust valve is damaged, it will cause the vehicle to emit blue smoke, and there is our fuel system, if the fuel system used is relatively low, there are more impurities. It will also lead to the problem of blue smoke in our engine, and if the problem is solved, the first thing to do now is to check whether the carbon deposit on the spark plug is much. If there are not many eggs on the spark plug, it is not to burn engine oil, you can replace the exhaust valve of this vehicle, and I wish you a happy life, everything goes smoothly, and everything goes well.

<> blue smoke is not necessarily burning engine oil.

Hello, dear, judging Duan Duan This refers to blue smoke, not necessarily burning engine oil, this is right, dear. If you emit blue smoke, you can't rule out the problem caused by the damage to the engine exhaust valve. If the exhaust valve is damaged, it will cause the vehicle to emit blue smoke, and there is our fuel system, if the fuel system used is relatively low, there are more impurities.

It will also lead to the problem of blue smoke in our engine, and if there is a solution to the problem of reputation, now the fault can first check whether the carbon deposit on the spark plug is much. If there are not many eggs on the spark plug, it is not to burn engine oil, you can replace the exhaust valve of this vehicle, and I wish you a happy life, everything goes smoothly, and everything goes well. <>

<> you are in a round shirt, dear, if you are troubleshooting in this inspection now, you can now remove the spark plug if you have time, and see if there is a lot of carbon on the spark plug. If there are not many, replace the fuel standard of this machine valve, and raise the fuel mark. If there is too much carbon on the spark plug in the gear cavity, it is a problem of burning engine oil.

In the case, we have to overhaul the piston ring and the engine to solve this problem, dear. Pro-<>

<> my car is coming up with blue smoke. But the oil is normal.

Hello, dear, if it is normal for the bridge to collapse and burn at that oil level, it is to emit those blue smoke. I'll give it to you, then you can replace our engine waste valve, waste valve. It's okay to replace this discarded valve alone, dear. <>

<>Yes, just clean him on the side of the fuel injector, and if you use fuel, raise the mark a little, and this problem can be solved. <>

Smile Lu Elimination Ruler] <>

Is there a problem with the spark plug that emits blue smoke?

Hello, dear, in this spark plug orange type, if the ignition gap is too large, and there is too much carbon on the upper area, it will lead to the problem of blue smoke caused by bad combustion, you can disassemble it and take a look, if the old fruit round guesses that the black carbon on the surface of the spark plug is too much, you can also solve this problem by replacing the spark plug for him, dear. <>
