Three situations in which the exhaust pipe smokes, be wary of the second one!

1. Black smoke from the exhaust pipe indicates that the mixture is too thick and the combustion is incomplete. The important reasons are: car engine overload; insufficient cylinder pressure; low engine temperature;Improper adjustment of the carburetor; blockage of the air filter; individual cylinder failure; ignition delay, etc.

2. There are generally three types of smoke from the car exhaust pipe: black smoke, blue smoke and white smoke. It is normal for the car exhaust pipe to produce white smoke, which is caused by the high temperature of the exhaust gas coming out of the exhaust pipe. It's not normal if there is black smoke.

3. The first reason is that the temperature is low. The gas discharged after the vehicle starts comes into contact with cold air, forming a low-pressure environment in an instant, and then a physical reaction occurs to form water mist or water droplets. The second reason is that after the vehicle is hot, some water droplets in the exhaust pipe will evaporate, resulting in the appearance of some fog.

4. White smoke The phenomenon of white smoke in cars is more common in autumn and winter, but different degrees of white smoke need to be treated differently. Once there is abnormal smoke, it needs to be paid attention to and repaired in time.

5. There are generally three types of smoke from the exhaust pipe: black smoke, blue smoke and white smoke. The exhaust pipe emits black smoke, and the car body will have a large engine shake, and the exhaust pipe will make an abnormal sound. At the same time, the black smoke will be discharged, and you will feel weak when accelerating. This is a real fault of the car body.

6. Black smoke from the exhaust pipe: it means that the engine mixture is too thick and the combustion is insufficient. When the air filter is too dirty, the spark plug is bad, the ignition coil fails, etc., it will cause black smoke from the engine.

What's wrong with the smoke from the car exhaust pipe?

1. It may be caused by the cylinder pressure of the car being too low, resulting in incomplete combustion. If gasoline is not completely burned, it will produce black smoke, which will be discharged from the exhaust pipe. There is a problem or malfunction of the car ignition system, such as spark plug leakage, too weak high voltage or weak jump fire, etc.

2. Black smoke from the exhaust pipe indicates that the mixture is too thick and the combustion is incomplete. The general reasons are that the car engine is overloaded, the cylinder pressure is insufficient, the engine temperature is too low, the carburetor is improperly adjusted, the air filter element is blocked, individual cylinders do not work, and the ignition is too late. After exclusion, it should be checked immediately whether the air barrier is fully open, and maintenance should be carried out if necessary.

3. The reason why the exhaust pipe smokes is: the air filter of the vehicle is stained, resulting in insufficient air intake; when the engine is running, the exhaust pipe discharges a large amount of water and white smoke; the high temperature in the cylinder will cause the gas to enter the oil sap shell; white smoke appears when the cold car starts, and as the temperature of the engine rises, the white smoke appears The elephant also disappeared.

4. Black smoke from the exhaust pipe: it means that the engine mixture is too thick, resulting in insufficient combustion. When the air filter is too dirty, the spark plug is bad, the ignition coil fails, etc., it will cause black smoke from the engine.

5. Teach you how to solve the problem of car smoke. Situation 1: Black smoke. Car body performance: The engine of the car shakes loudly, and the exhaust pipe makes an abnormal sound. At the same time, black smoke is discharged, and it feels weak when accelerating.

Teach you to solve the problem of car smoke

1. Valve oil leakage, valve oil leakage is generally caused by valve blockage or damage, and the solution is to replace the valve. 2. The connector is loose. The solution is to tighten the connector or replace it. 3. That is, there is something wrong with your pump and hydraulic oil pipe.

2. Treatment: Check whether the engine cylinder block and cylinder pad are damaged, and check whether there is water in the fuel tank. Check the car manual and add gasoline with the correct label in strict accordance with the manufacturer's regulations.

3. If the car smokes, you should immediately check whether the engine cylinder block and cylinder pad are damaged, and see if there is water in the fuel tank. Old vehicles should be repaired at the service station in time. There are three kinds of smoke from the car engine: white smoke, black smoke and blue smoke.

4. The solution to the smoke from the car burning oil: the choice of oil, the oil is very important for the vehicle's engine, which can not only lubricate, but also clean, cool, anti-rust, seal and other functions. If the vehicle has a slight burning of oil, using better quality oil can effectively relieve it.

5. The reason for black smoke is that the fuel is not fully burned or the empty air filter is too dirty, and the spark plug is not good. When the vehicle emits black smoke, the fault should be observed immediately. If the black smoke is caused by oil leakage, it should be treated according to the leakage location. For example, if the steering power oil leaks, the power box, oil pipe, etc. It should be checked and then tightened.
