The FAW 4102 engine emits blue smoke from starting

The consumption of this lubricating oil is mainly caused by the blue smoke of the cool car

The upper combustion of the engine: the aging of the valve seal, the clearance of the valve guide is too large, the lower combustion of the engine is not working well of the crankcase ventilation check valve: the matching gap between the piston and the cylinder block is too large, the tension of the piston ring is reduced or stuck, and the strain of the cylinder wall In fact, the lubricating oil is also normal consumption in good condition, and the standard consumption is generally not more than liters per 1,000 kilometers.

But when the car is in poor condition, some cars will emit blue smoke from the exhaust, in fact, this means that the lubricating oil consumption is too large, generally speaking, the abnormal consumption of lubricating oil is nothing more than two situations, entering the combustion chamber to participate in combustion, or oil leakage.

In this case, you need to pay attention to whether there is blue smoke at the moment of start-up or a slight combustion during driving, at this time, you can use the sunlight ** when the engine speed is stable at about 2500 rpm when the sun is shining** whether the gas color of the exhaust pipe is blue. If it is, it means that the piston ring is not strong enough or stuck in the piston ring groove, if it is only an instant blue smoke, it means that the valve oil seal rubber is too hard and the seal is not tight.

In this case, it is recommended to check the valve oil seal and piston ring.

Hello. The engine burned oil.

Hello, there are generally two common cases of blue smoke from the engine:

1.Scratches on the inner wall of the cylinder, poor piston sealing, or severe wear of the valve will produce gaps, and the oil that was originally responsible for lubrication will enter the combustion chamber through these gaps to participate in combustion, and the oil that cannot be burned will produce blue smoke when it is discharged out of the car.

2.In addition, excessive oil filling will also easily lead to oil burning, excess oil will be brought into the cylinder for combustion, resulting in oil burning, and excessive oil will also hinder the normal operation of the crankshaft arm, allowing it to do additional work and increase energy consumption.

The engine used in the motor vehicle is a kind of machine that can convert other forms of energy into mechanical energy, when the engine of the motor vehicle is running, it is necessary to use oil to lubricate the internal parts, only when the parts are fully lubricated, the engine can run normally, once there is too much or too little oil, it will lead to the engine abnormality.

Yangchai seems to be a diesel engine with blue smoke (a tired engine will also have it).1.Loosen a little high-pressure pipe, look at the lower discharge pump, how the oil supply is, and remove the fuel injector for side test.

Detection of atomization).2.It is better to smell the smell of smoke, whether it is the smell of diesel, or the smell of engine oil (the smell of engine oil opens the cover and check the valve,) 3 diesel engine.

Burning engine oil and burning diesel fuel are white smoke weight (can only be inferred by taste) 4 Look at the water and oil in the tank. The two can be opened when they come together. 5. Check the ignition timing, (important,).

Causes of blue smoke from engine exhaust pipes:

1. Improper use of engine oil.

In many cases, the main reason for the white smoke emitted from the start of the car is that due to the use of substandard engine oil, the engine will be loaded under the long-term high-temperature operation of the car, the power of the oil pump pump is insufficient, and it will affect the life of the engine, and it will cause the engine to burn oil.

2. Poor piston sealing.

There is also a situation where there are scratches on the cylinder wall, poor piston sealing, and valve wear resulting in gaps, which enter the gasoline combustion chamber to participate in combustion, and when the combustion is not full. When it is divided, it produces blue smoke.

3. Wear and tear of pipes and valves.

When pipes and valves are worn, excess oil enters the combustion chamber and burns can lead to the formation of blue smoke from the exhaust pipe of the car.

It is normal for the new car to burn some oil, because the engine is not running-in, fortunately, the fuel injection of the injector is not smooth, this needs to be broken cylinder experiment, and there is to see if the oil is added too much, the oil dipstick has 2 scales, and the oil is added to the first scale and the second scale is just right.

Is there a decrease in engine oil, generally eating engine oil will cause blue smoke.

The blue smoke is mainly due to the excessive amount of engine oil burning in the combustion chamber, which is mostly related to engine wear, and may also be related to the incorrect selection of the viscosity of the engine oil, the specific situation is as follows:

1. Normal wear and tear of the engine.

Due to the age of the engine, the wear between the working parts is intensified, resulting in a larger gap and a decrease in sealing performance, and the oil is transferred to the cylinder through other parts to participate in combustion, resulting in blue smoke.

2. Abnormal wear and tear of the engine.

Due to the fact that the friction components are not fully lubricated during the use of the engine (long-term lack of oil or oil and filter; The engine is cooled and the throttle is working, etc.), resulting in abnormal wear and tear of the engine, causing oil leakage and combustion, and producing blue smoke.

3. The viscosity of the engine oil is not selected correctly.

It is manifested as no blue smoke when starting in the morning, after the hot car, there will be a small amount of blue smoke discharged, there was no blue smoke before, after changing another engine oil, the blue smoke is generated, and there is a speed acceleration function when accelerating, but the oil consumption is too fast, and the engine noise increases.

Blue smoke fault disposal:

1. If the engine starts in the cold engine state and emits blue smoke, the engine needs to be disassembled, the valve oil seal needs to be replaced, and the full set of valve oil seals is generally replaced.

2. If the engine emits blue smoke during acceleration, it needs to be disassembled to determine whether the specific cause is too large the gap between the piston and the cylinder, or the piston ring matching problem.

3. The engine is emitting blue smoke at any time. If the engine emits a lot of blue smoke no matter what the operating conditions are, it proves that the engine is already very worn and must be overhauled.

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.

In the inertial thinking of car friends, it is always believed that the piston ring stuck oil should be overhauled, so that it is not only necessary to bear the high maintenance costs, but also to bear the risk of unpredictable omen and depreciation losses caused by the overhaul of the vehicle. Destroy the airtightness and precision of the engine. Moreover, after tens of thousands of kilometers, there is still a rollable rolling energy to burn the engine oil again, so it is unsustainable to overhaul the engine.

Now the no-dismantling technology has been very mature and gradually accepted by the majority of car owners. In particular, the non-destructive repair products containing PNF patented technology have completely gotten rid of the technical shackles of burning engine oil and having to go to the auto repair shop for overhaul, without removing a screw, repairing and releasing the piston ring stuck engine oil while driving, with remarkable results.

The reason for the blue smoke of the diesel engine is generally caused by the oil participating in the combustion, which is commonly known as "burning engine oil", but there are also diesel engines that emit blue smoke not caused by burning engine oil, but due to poor atomization of the injector, the use of inferior diesel, the wrong time of fuel supply, and the lack of strict valve sealing.

The main reasons for the blue smoke of "burning engine oil" are as follows:

1. The oil level of the oil pan is too high. The high-speed rotation of the crankshaft will drive the oil to splash on the cylinder wall and enter the combustion chamber.

2. The oil level of the oil bath air filter is too high. If the oil level of an oil bath air filter is too high, the oil in the air filter will be drawn into the combustion chamber and the oil will burn.

3. The cylinder liner, piston and piston ring are seriously worn, and the clearance is too large. Serious wear of cylinder liners and pistons will cause the oil to flow up to the combustion chamber for combustion, at this time, the exhaust gas of the engine crankcase will increase, and the lower exhaust gas will appear, and the worn cylinder liners, pistons and piston rings should be replaced.

4. The piston ring is counterparted, the piston ring is broken, the piston ring opening gap is too large, the side clearance is too large, and the piston ring inner and outer incision (or chamfering angle) is reversed. These will cause the oil to enter the combustion chamber through the piston ring counterpart, fracture, opening gap, and side clearance, forming oil burning.

5. The gap between the valve and the valve guide is too large. The gap between the valve and valve guide will cause a large amount of oil to be sucked into the combustion chamber to burn, resulting in oil burning, at which point the worn valve and guide should be replaced.

6. Turbocharger leaking oil. The turbocharged engine appears exhaust blue, but the power of the engine has not decreased significantly, and the organic oil stain on the compressed air outlet of the turbocharger or the intake hose is mostly the turbocharger leakage, and the oil enters the combustion chamber with fresh air, resulting in the burning of oil, and the supercharger should be replaced at this time.

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

If there is no obvious fault in the engine, then the blue smoke is burning the engine oil.

The engine emits blue smoke, generally because the fuel combustion is not sufficient, the engine oil is burned, the three-way catalysis is not smooth, etc., it is recommended that you go to the repair shop to check.

1. Maybe add more engine oil. 2. The piston ring is overworn, and if the oil is burned, the engine is about to be overhauled!

It shows that the engine oil enters the combustion chamber to participate in combustion, the piston ring and the cylinder liner are not completely run-in, and the oil enters through the gap; The piston ring is bonded in the groove, and the cone surface of the piston ring is reversed, losing the effect of oil scraping; The piston rings are worn excessively, and the oil runs into the combustion chamber through the opening gap; The oil pan oil level is too high; The valves and tubes are worn out, and the clearance is too large. It can be solved by the following methods: the new car or overhauled locomotive must run in the engine according to the regulations, so that the parts can be meshed normally; Look at the assembly mark clearly and install the piston ring correctly; Replacement of qualified or oversized piston rings; Find out the reason for the increase in the oil pan oil level and release the excess oil from the oil pan; Reduction of oil in the filter pan; Replace the valve guide.

It is recommended to go to a professional repair facility to check and rule it out.

Hello, the blue smoke from the exhaust of the car is because during the working process of the engine, the oil enters the engine cylinder and burns together with the gasoline, so the exhaust gas will be black, which is what we often call "burning engine oil"! Generally, there are several reasons:

1. The gap between the piston and the piston ring becomes larger, the piston ring is too worn, and the cylinder liner is overworn, which causes "pump oil";

2. The gap between the valve guide sleeve and the valve stem is too large and leaks;

3. The cylinder gasket oil circuit hole is connected with the cylinder, referred to as "oil and gas mixing".

Hope it helps.

When you get up in the morning, the blue smoke is generally due to the failure of the valve oil seal, and it is generally necessary to repair it. If the cylinder pressure is normal, the oil pump injection time is too late, and the oil pump can adjust the fuel injection nozzle on the line. But now you have replaced the piston ring, the cylinder pressure should be normal, you have to take a closer look at the current emergency throttle is gray beam smoke or blue smoke, if it is gray smoke is normal, if the blue smoke is going to the repair shop to check the cylinder pressure, if the cylinder pressure is low may need to be repaired or overhauled, if the cylinder pressure is normal, change a set of gas rotten state door oil seals.

Summary. Hello, dear, I'm honored to answer for you! <>

When the weather is cold, the 4105 engine is not easy to start in the morning, and there is a phenomenon of blue smoke after starting, the reason is that the valve guide and the tube bearing hole are not tightly sealed, resulting in oil leakage into the combustion chamber; 2. Failure to maintain in accordance with regulations; 3. Long-term incorrect driving mode, long-term lack of engine oil, long-term overload operation, etc., resulting in premature aging and wear of the engine.

It's cold The 4105 engine is not good to start in the morning, and there is a phenomenon of blue smoke after starting, what is the reason?

Hello, dear, I'm honored to answer for you! <>

When the weather is cold, the 4105 engine does not start well in the morning, and there is a phenomenon of blue smoke after starting, the reason is that the valve guide and the catheter bearing hole are not tightly sealed, resulting in oil leakage into the combustion chamber; 2. Failure to set up and maintain the sedan car in accordance with the regulations; 3. Incorrect driving mode during the long sail period, long-term lack of engine oil, long-term overload operation, etc., resulting in premature aging and wear of the engine.

The blue smoke emitted from the engine cool start is the phenomenon of burning engine oil in the vehicle, which is manifested as: the exhaust pipe has a black and wet sludge accumulation, accompanied by particulate matter, and smells the organic oil smell. Blue smoke from cold start, proving that after the vehicle is turned off, the oil enters the combustion chamber, and when the engine is started, the oil in the cylinder will burn together with the mixed gas at high temperatures, resulting in blue smoke.

The reasons for the blue smoke from the cold start of the engine are: 1. The car uses unqualified engine oil or the engine oil has not been replaced for a long time: the oil in the car is too thin and the combustion is not sufficient, resulting in the phenomenon of blue smoke in the car.

2. The quality of the mixed gas involved in combustion is not good: the filter is damaged by aging and not being replaced. 3. The catheter and valve are seriously worn out in the process of work

The gap between the two is too large, and during the air intake, excess oil in the rocker chamber is sucked into the combustion chamber for combustion, resulting in the generation of blue smoke. The following are some other contents to imitate Qingshao: 1. Introduction and types:

An engine is a kind of machine that can convert the energy of other forms of holding into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. For example, the internal combustion engine usually converts chemical energy into mechanical energy. 2. Scope of application and history:

An engine applies to both a power generator and an entire machine including a power unit. The engine was first born in England, so the concept of the engine is also derived from the English language, and its original meaning refers to the "mechanical device that produces power".
