What's wrong with the white smoke from the exhaust pipe of the diesel engine

The original white smoke from the diesel engine Because of the following points: the engine temperature is low. When the engine is just started or the outside temperature is low, white smoke is obvious. This is because the temperature of the engine itself is low, and the combustion chamber and gasThe temperature of the cylinder wall is also low, and the fuel mist cannot be completely mixed evenly with the air, which reduces the quality of the combustible mixture.

The reasons why the exhaust pipe has white smoke are: the temperature is not enough. Because the engine temperature is not enough, the mixture of fuel and air sprayed into the cylinder cannot be burned, and the exhaust pipe has white smoke.

Some diesel oil has not been burned and turns into oil vapor, with white smoke. 4) Poor atomization of the fuel injector. Poor atomization causes the diesel to not be completely burned, and the high-temperature exhaust gas discharged from the normal working cylinder converges in the exhaust pipe, resulting in white smoke. 5) The cylinder pressure is too low. Some diesel fuel turns into oil vapor without combustion, so white smoke comes from the exhaust pipe.

Diesel has poor atomization. The reasons are: the fuel injection pressure is too low, the fuel injector is seriously dripping, or the fuel injector pressure is adjusted too low, causing some diesel oil mist to fail to catch fire in the combustion chamber and make white smoke.

The air filter is not clean. If the air filter is not clean, it will cause an increase in resistance, a decrease in air flow, and a decrease inflatation efficiency, resulting in insufficient engine power. The diesel air filter element should be cleaned or the dust on the paper filter element should be removed as required, and the filter element should be replaced if necessary.

When the diesel engine is first started or in a cold state, the exhaust pipe has white smoke, which is caused by the evaporation of oil and gas at low temperatures in the cylinder of the diesel engine, especially in winter. When the diesel engine runs in cold weather, the temperature of the diesel engine is low, and the temperature of the exhaust pipe is also low. It is a normal phenomenon that the exhaust vapor condenses into water vapor to form white smoke exhaust.

Yunnei d25 engine exhaust pipe drips white smoke

The reasons why the exhaust pipe has white smoke are: the temperature is insufficient. Due to insufficient engine temperature, the mixture of fuel and air sprayed into the cylinder cannot be burned, and the exhaust pipe smokes white smoke.

Dripping from the exhaust pipe of the car is a good phenomenon, which proves that the fuel has been fully burned in the engine, and the exhaust pipe of the car will drip out. In fact, this is a very normal phenomenon.The reason why the exhaust pipe drips water is because the ambient temperature is relatively low, and water and carbon dioxide are produced after the complete combustion of gasoline.

Causes and solutions for white smoke from the engine exhaust pipe: Insufficient temperature: Due to insufficient engine temperature, part of the mixed gas formed by the fuel and air sprayed into the cylinder cannot burn the exhaust pipe to make white smoke.

Is it normal for car exhaust to have white smoke? What is the reason?

1. The reason for the white smoke in the exhaust of the car is that 1 the normal combustion of gasoline 2 the cylinder cushion is damaged. After the normal combustion of gasoline, water and carbon dioxide are produced, and the water becomes water vapor when it encounters high temperatures. When it is discharged from the exhaust cylinder, it will condense into water mist, and these water mists It's the so-called white smoke, which is a normal phenomenon.

2. The white smoke from the exhaust gas may be caused by the engine coolant entering the combustion chamber. There are many reasons for the white smoke from the exhaust of the car, one of which is that the coolant has entered the combustion chamber. When the coolant enters the combustion chamber, it will evaporate at high temperatures to produce white smoke.

3. The white smoke may be due to the wear of the cylinder pad of the engine cylinder, resulting in a certain gap, resulting in a large amount of water from the heat dissipation system entering the combustion chamber.

4. This is because gasoline contains moisture, and the engine is too cold. At this time, the fuel entering the cylinder is not completely burned, resulting in fog or water vapor to form white smoke. In winter or in the rainy season, when the car starts for the first time, white smoke can often be seen. It doesn't matter. Once the engine temperature rises, the white smoke will disappear. This situation does not need to be overhauled.

5. A large amount of white smoke from the exhaust gas of the car is that the piston of the engine is broken and the oil begins to burn.The dark white in the exhaust gas is naturally due to the high content of water in the exhaust gas. There is too much moisture in gasoline.

6. If it weren't for winter, it wouldn't be normal. It may be malfunctioning. The engine exhaust pipe of the car emits a lot of white smoke when driving. One is milky white, the other is water vapor white smoke, and there are water droplets at the outlet of the exhaust pipe.

What's wrong with the white smoke from the car

There are five reasons for the white smoke from the car's exhaust: the air filter of the vehicle is polluted, resulting in insufficient air intake. Solution: Clean the air filter in time. The carburetor fails, or the oxygen sensor in the exhaust pipe is contaminated, causing the computer to be unable to provide correct gas distribution information. Solution: Go to 4S for repair.

Car exhaust gasThe reason for white smoke is that 1 gasoline burns normally 2 the cylinder cushion is damaged. After the normal combustion of gasoline, water and carbon dioxide are produced, and water becomes water vapor when it encounters high temperature. When it is discharged from the exhaust cylinder, it will condense into water mist. These water mists are called white smoke, which is a normal phenomenon.

The white smoke from the exhaust gas may be caused by the engine coolant entering the combustion chamber. There are many reasons for the white smoke from the exhaust of the car, one of which is that the coolant has entered the combustion chamber. When the coolant enters the combustion chamber, it will evaporate at high temperatures to produce white smoke.

What's wrong with the white smoke from the exhaust pipe

The reason for the white smoke from the exhaust pipe is that the temperature is not enough, the engine temperature is not enough, forming a mixture of fuel and air injected into the cylinder, part of it cannot burn, and white smoke comes out of the exhaust pipe. .

When the exhaust pipe of the car has white smoke, it may be because the air filter of the vehicle is stained, resulting in insufficient air intake, or it may be due to the failure of the carburetor, or the oxygen sensor in the exhaust pipe is polluted, resulting in the computer's inability to provide the correct gas distribution. The information of.

Because of the low temperature, the engine exhaust pipe smokes white smoke. During the operation of the engine, the exhaust gas will condense instantly after encountering low temperatures in the outside world, and the resulting water vapor will produce a large amount of misty white smoke. The engine temperature is too low. Part of the diesel becomes oil vapor when it is not burned, and the exhaust gas is discharged from the exhaust pipe, emitting white smoke. There is water in the oil supply system.

The white smoke in the exhaust gas is caused by the engine burning coolant, which may be caused by cracks in the cylinder block or cylinder pad.In this case, check the cylinder block and cylinder pad. If the cylinder block is cracked, it should be replaced. If the cylinder pad is cracked, it should be replaced.

When the car is just on fire, the exhaust pipe and the air in the exhaust pipe are cold. When the water vapor is discharged from the cylinder, it will condense into water mist, which is white smoke.

One is milky white, the other is water vapor white smoke, and there are drops of water at the mouth of the exhaust pipe. Cause of failure: When the engine is running, the exhaust pipe discharges a large amount of white smoke. There are two situations: the exhaust pipe discharges milky oil mist. The main reason is that the fuel vaporization is poor, and it is discharged from the exhaust pipe without combustion, forming milky white smoke.
