What is the reason for the Cruze 3 cylinder misfire exhaust pipe emitting thick smoke?

Causes of smoke from the Cruze three-cylinder misfire exhaust pipe:

A misfire means that the three cylinders do not work and do not burn.

As a result, the fuel injected into the three cylinders is discharged directly into the exhaust pipe without combustion, and when it hits the high-temperature exhaust pipe, it ignites, so it produces a large and thick smoke.

Therefore, if this problem needs to be solved, it is necessary to solve the fault of the misfire of the three cylinders.

The lack of cylinders leads to insufficient engine power, and the engine automatically increases the amount of fuel injected.

1. Black smoke from the exhaust pipe: fault judgment: true fault. Cause analysis: It indicates that the mixture is too concentrated and the combustion is incomplete. The main reason is the car engine.

Overload, insufficient cylinder pressure, low engine temperature, carburetor.

Improper adjustment, air cleaner.

Blockage, individual cylinders not working and late ignition, etc. When excluding, check whether the choke is fully opened in time, and overhaul if necessary; After the flameout, look at the main nozzle from the carburetor mouth, if there is oil injection or oil dripping, the oil level of the float chamber is too high, it should be adjusted to the specified range, and the main measuring hole should be tightened or replaced; Air filter.

Blockages, which should be cleaned, unclogged or replaced.

2. The exhaust pipe of the vehicle emits blue smoke: fault judgment: true fault. Cause analysis: It is caused by a large amount of oil entering the cylinder and not being completely burned. Remove the spark plug.

Serious carbon deposits can be detected. It is necessary to check whether the oil level of the dipstick is too high; whether the gap between the cylinder and the piston is too large; Whether the piston ring is reversed; Whether the intake valve guide is worn or sealed.

whether it is damaged; Whether the cylinder head gasket is ablated, etc., should be repaired if necessary.

3. White smoke from the exhaust pipe of the vehicle, serious when the car is cold, and no white smoke will be emitted after the car is hot: fault judgment: false fault. Cause analysis: This is because the gasoline contains water, and the engine is too cold, at this time, the fuel entering the cylinder is not completely burned, resulting in fog spots or water vapor.

Produces the formation of white smoke. In winter or during the rainy season, when the car is first started, white smoke can often be seen. It doesn't matter, as soon as the engine temperature rises, the white smoke disappears. This condition does not need to be serviced.

4. The engine noise is large, and when the vehicle steps on the accelerator pedal in place, there is a "rumbling, rumbling" abnormal sound, and there is a sense of vibration in the engine compartment. Fault Judgment: Class faults are used.

Cause analysis: When lifting the vehicle, you can see that the bottom guard of the engine has bump marks. If there is an obstacle on the road and you force your way through, the underside guard will be bumped.

If the distance between the bottom pan and the engine oil pan becomes closer after deformation, the collision between the oil pan and the bottom guard plate during acceleration will make an abnormal noise and make the body vibrate.

There are two cases for this:1White smoke comes out of the exhaust pipe of the vehicle, and it doesn't come out when the car is hot:

Don't worry about this problem, because gasoline contains water and the engine is too cold, and the fuel entering the cylinder is not completely combusted, resulting in fog spots or water vapor to form white smoke. It is more noticeable in winter or during the rainy season. When the engine temperature rises, the white smoke will disappear, and this does not need to be repaired.

2.The hot car has not disappeared, that is, whether the antifreeze is enough, check and replenish it in time. It is also possible that the engine is boiling water, and the only reason for this is to replace the cylinder gasket.

Hello, glad your question, the reason for the black smoke from the Chevrolet Cruze engine 1The flammable mixture is too thick. 2.

There is too much oil in the engine fuel. 3.Poor sealing of piston rings or crankshaft oil seals.

4.There is moisture in the fuel. 5.

Bad spark plug 6The air filter has a dirty transport chain. You need to detect defeats.

Hope it helps.

Summary. Hello, happy to answer your <>

The Cruze engine could not add a little throttle, and the exhaust pipe emitted a lot of white smoke. There is organic oil in the intake branch pipe, and the spark plug is directly blackened Reasons: 1. When the engine is running, a large amount of water vapor and white smoke is discharged from the exhaust pipe, and whether there is water accumulation in the fuel tank, whether the cylinder gasket is damaged, whether the cylinder block is cracked, and whether the cylinder liner sealing ring is good.

2. The temperature is low and the cylinder pressure is insufficient, and the fuel atomization is not good, especially the exhaust smoke in the early stage of cold start. 3. The water content in the fuel is large, and white smoke comes out of the exhaust when starting cold.

The Cruze engine was unable to add a little throttle, and the exhaust pipe emitted a lot of white smoke. There is organic oil in the intake branch, and the spark plug is directly black. May I ask what is the reason for the Wang clan?

The Cruze exhaust emits a lot of white smoke.

Hello, happy to answer your <>

The Cruze engine could not add a little throttle, and the exhaust pipe emitted a lot of white smoke. There is organic oil in the intake branch pipe, and the spark plug is directly blackened Causes: 1. When the engine is running, a large amount of water vapor and white smoke is discharged from the exhaust sun-spine trachea, and whether there is water accumulation in the fuel tank, check whether the cylinder gasket is damaged, whether the cylinder block is cracked, and whether the cylinder liner sealing ring is good.

2. The temperature is low and the cylinder pressure is not sufficient, and the fuel atomization is not good, especially the exhaust smoke in the early stage of cold starting. 3. The water content in the oil seepage during combustion is large, and the exhaust gas emits white smoke when the cold starts.

Sometimes you can't fill up the gas, and the engine clatters a few times when the smoke is heavy.

Dear, there is a lot of white smoke from the Cruze exhaust is to check the spark plugs, and found that there is oil stain on the electrode keys of the 3rd and 4th cylinder spark plugs.

Dear, sometimes you can't add oil, and when the smoke is heavy, the engine clicks a few times, which is a problem with the throttle and cylinder volume carbon.

Appeared out of nowhere.

Lots of white smoke.

Is there water in the gasoline?

Kiss, if it suddenly appears, it is caused by water in it.

Kiss, if a lot of white smoke suddenly appears, it means that there is water in the gasoline.

Kiss, there's water in the gasoline.

Expansion: The automobile engine is the device that provides power for the car, and it is the heart of the automobile reform, which determines the power, economy, stability and environmental protection of the car. Depending on the power**, car engines can be divided into diesel engines, gasoline engines, electric electric motors, and hybrids.

Common gasoline engines and diesel engines belong to reciprocating piston internal combustion engines, which convert the chemical energy of fuel into mechanical energy of piston movement and output power to the outside world.

1.Blue Hall smoke is mainly caused by the combustion of engine oil in car engines. The oil will enter the engine in a variety of ways, burn in the engine, and the car will emit white smoke.

Replace the oil that is not qualified. 2.There is too much oil in the oil pool of the fuel tank, and the crankshaft when rotating at high speed will cause the oil to splash into the combustion chamber due to combustion; Extract the amount of oil that has been searched too much.

3.The valve seal is aging and the hardening cannot expand and contract with the thermal expansion and contraction of the valve temperature, resulting in cold oil entering the cylinder from the oil seal. Replace the valve.

Most of the cars on the market now burn engine oil, and most of them are French cars, German cars, and BMW cars.

The main reason for burning engine oilIt is the problem with the fittings, the wastegas valve, the valve seal, the cylinder pulling the cylinder, and the cylinder pressure is insufficient.

It is a long-term unclean oil circuit, the antifreeze is not replaced in time, the oil service life is too long, 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. 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 have to find out the reason for your burning oil, and you can refer to it if you have repaired it with a repair agent before.

Not a major overhaul to solve the problem of burning engine oil.

Summary and solutions for burning engine oil for various models.

Why does the Cruze engine compartment smoke, and the smell of oil smoke is often caused by burning engine oil.

Automobile engine smoke exhaust is often caused by burning engine oil, at this time, it should be checked whether the engine cylinder liner is worn, whether the sticky ring, ring alignment, valve seal ring aging and deformation, valve guide clearance is too large, etc.

Combustion problems, can not be fully burned after injection, but because the engine temperature is low and high idle speed is required, the signal given by the engine computer is more fuel injection, combustion is not sufficient, it is recommended to use brand gasoline, of course, it is also necessary to consider the spark plug mileage time is enough for 30,000 kilometers, it is recommended to replace the washing nozzle or something can be alleviated [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Blue smoke is the performance of burning engine oil, the combustion chamber of the cold car engine is not tightly sealed, part of the oil is mixed into the combustion chamber and burned, and there is no such phenomenon after the hot car is well sealed, in short, it is better to check it in the store.

1. The black smoke from the exhaust pipe is caused by excessive concentration.

2. Your car performs high suction power in the engine valve chamber cover, and black smoke comes out of the exhaust pipe. The biggest possibility is that the engine exhaust valve is damaged, causing the oil engine to enter the throttle position to produce carbon deposits, which in turn affects the air supply of the engine and the mixing ratio of the engine mixture.

3. A. Check whether the air release valve is damaged, and replace it with a new one if it is damaged; b. Clean the throttle and match the data for the throttle.

The black smoke is usually caused by the mixer being too thick, and it is estimated that your car is still running after the maintenance period. Excluding the factors of the circuit, there are reasons such as dirty throttle and carbon accumulation of spark plugs in the oil circuit.

If the PVC valve is broken, that is, the crankcase forced ventilation valve, the oil cap will not be pulled out at all when the fire is ignited, and all the oil will be sucked into the air intake, resulting in insufficient combustion.
