What s going on with the white smoke of the light of Wuling

White. Body performance: When the car is on, a large amount of white water vapor can be seen coming out accompanied by the engine running unsmoothly, even if the engine is preheated to reach the normal working water temperature, a large amount of water vapor still comes out. (except in winter).

Cause of failure: The white smoke may be due to the wear of the cylinder gasket of the engine cylinder, which produces a certain gap, resulting in a large amount of water from the heat dissipation system entering the combustion chamber. Water cannot be burned, and when heated, water vapor is generated, which is discharged directly from the exhaust pipe.

Solution: 1Check whether there is damage to the engine block and head gasket, and check whether there is water in the fuel tank.

2.Check the car manual and add the correct gasoline in strict accordance with the manufacturer's regulations.

Note: When the car is warmed at low temperature, a small amount of white exhaust gas will come out, which is a normal phenomenon of cold and heat exchange, and the white smoke will disappear naturally after the car is warmed up, which is a normal phenomenon.

Blue smoke. Body performance: The explosive power of the vehicle decreases, the acceleration is weak, the noise becomes louder, the exhaust pipe has blue smoke discharge, and the smell of burnt oil caused by the combustion of organic oil.

By checking the oil scale, it will also be found that the consumption of oil is too large, under normal circumstances, after 7500 kilometers of maintenance, the consumption of oil should be within the normal range, no need to replenish halfway.

Cause of failure: Blue smoke is mostly due to internal faults in the engine, resulting in oil channeling into the combustion chamber for combustion, and there are generally two common situations:

One is severe wear and tear. 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.

In addition, overfilling of engine oil can also easily lead to oil burning. Some car owners mistakenly think that the more oil you add, the better, but they don't know that excess oil will also be brought into the cylinder for combustion, resulting in the phenomenon of burning oil; At the same time, excess oil can also hinder the normal operation of the crankshaft arm, allowing it to do extra work and increase energy consumption.

Solution: 1For older vehicles, the sealing of cylinder blocks, pistons and other components should be checked frequently, and when blue smoke is found, it should be repaired at the maintenance station in time to prevent greater losses.

2.Add an appropriate amount of engine oil, too much or too little is not advisable.

3.Check the oil usage regularly, and if you notice any abnormal oil consumption, check it immediately.

This is the exhaust gas processor is broken, repair the handle.

It's normal for the weather to be cool and white smoke, but the blue smoke burns the engine oil.

Check that the injector is working properly.

Haha, the engine is ready for an overhaul.

In fact, it is not necessarily said that the white smoke from the exhaust pipe is a mechanical failure, we need to consider it on a case-by-case basis.

1. Cold start.

When the exhaust pipe suddenly emits a large amount of white smoke. This situation is very normal, because there is too much moisture in the gasoline when the car starts cold, so the moisture will evaporate after the start, resulting in a lot of white smoke in the exhaust pipe, and we only need to warm up the engine fully after this situation will disappear;

2. Blue smoke comes from the exhaust pipe. This is not the case, and blue smoke is usually evidence of engine oil burning.

Phenomenon, the co-combustion of engine oil and gasoline leads to increased pollution. The main reason for burning engine oil is that the engine piston ring is aging and the air tightness is reduced, and the engine oil has the opportunity to enter the combustion chamber to participate in the combustion process;

3. Black smoke comes from the exhaust pipe. Most of the smoke in the exhaust pipe is caused by the fuel not being fully combusted, so you can choose to drive to the repair shop to check it. Of course, poor quality gasoline can also cause this phenomenon.

The cylinder liner has cracks or the cylinder gasket is damaged, along with the cooling water.

As the temperature and pressure rise, the cooling water enters the cylinder. Water mist or water vapor can easily form when venting.

2. The atomization of the injector is poor, the injection pressure is too low, and there is a dripping phenomenon. In the cylinder, the fuel mixture is uneven, the combustion is incomplete, a large number of unburned hydrocarbons are produced, and water mist or water vapor is easy to form when exhausting.

3. The oil supply angle is too small and leaks. Too little fuel is injected into the cylinder before the piston goes up to the cylinder top, forming a thinner combustible mixture, and the late injection reduces the amount of premixed fuel in the front block, and the amount of premix is reduced. The pre-mixture gas is reduced, the combustion rate is reduced, the combustion ends late, and the combustion forms a large amount of water vapor smoke.

Due to wear and tear on the gasket of the engine cylinder.

On January 18, 2010, SAIC-GM-Wuling, the largest microbus enterprise in China, took the lead in making efforts to replace the new Wuling Light, a replacement product of the classic microbus Wuling Light, was officially listed in Jinan, aiming at the largest mid-range microbus market. Yuan Zhijun, deputy general manager of SAIC-GM-Wuling, said that the new Wuling Light, as the company's main product in 2010, will promote the product replacement of the mid-end micro-passenger market.

It is understood that the cumulative production and sales volume of Wuling Light has reached 2.16 million units in the past seven years, which is currently the fastest growing and largest single-platform model in China. In 2009 alone, Wuling Light's sales volume was close to 600,000 units, becoming the backbone of SAIC-GM-Wuling's annual production and sales of more than 1 million units. The total sales volume of Wuling Rongguang, which was launched on the basis of the Wuling Light platform, has approached 300,000 units in less than two years after its launch, making it the fastest growing model in China.

1. There is a problem with the air filter. When the car's air filter is stained and the air intake is insufficient, there will be white smoke from the exhaust pipe.

2. The carburetor is faulty.

3. There is a problem with the oxygen sensor in the exhaust pipe, which causes the sensor to not provide correct information.

4. There is too much water in gasoline.

Causes of white, black, and blue smoke from cars:

White smoke: mainly water vapor, which is very obvious when the cold car is on the car in the winter when the temperature is low, if it disappears after a period of time, it is normal, but if the peel pomace fruit emits white smoke for a long time, and there is water dripping out of the exhaust pipe, it may be that the person who opened the door to open the water and enter the water.

Blue smoke: mainly engine oil, if the engine emits blue smoke, it is basically the engine burning oil, and at the same time, the oil level will be low, it is best to go to the 4S shop to check.

Black smoke: The mixture is too thick, which means that the fuel injection volume is not up to standard, and there may be a leak in the fuel injector, a plug in the oil pipe, or too much carbon in the engine.
