Experience in looking at exhaust smoke to diagnose car problems
(Baonghean.vn) -Just by observing the color of smoke coming out of your car's exhaust pipe, you can diagnose some "diseases" your car is having to quickly fix them.
Excess smoke emissions indicate a problem with the car's engine. Even for diesel cars (which emit more smoke than gasoline engines), owners should pay attention to the color of the smoke because, according to car care and maintenance experts, this is the simplest way to detect a car's problem.
1. Thick white smoke

Usually we don't have to worry about white smoke if it is thin like vapor. This is a normal phenomenon due to the accumulation of gas in the exhaust pipe.
Thicker smoke, however, is more serious and could be related to engine coolant. This could be the result of a blown head gasket or a damaged cylinder head, or a cracked engine block. Repairs can be expensive.
2. Blue exhaust smoke
 |
This phenomenon occurs when your car engine is burning lubricating oil. This happens because the cylinder is damaged, the piston is loose, causing lubricating oil to leak into the combustion chamber, causing the sensors to deteriorate.
Although blue smoke is rare, if you experience it and continue to drive your vehicle, it can lead to serious damage to your vehicle.
The first thing to do is to check the oil level; if the oil is low, add more oil immediately. Do not let the engine run too much without lubrication, it will cause more serious damage to the engine.
3. Black exhaust smoke

Black smoke from a car indicates that the engine is burning too much fuel during operation. For gasoline engines, you need to have the carburetor adjusted or the electronic fuel injection system re-tuned.
Black smoke can also be caused by other reasons such as a faulty vent valve or cylinder head. Leaking oil or coolant into the combustion chamber can also cause black smoke.
4. Gray smoke
 |
When the car emits gray smoke, the owner should check the coolant system for oil when the engine is cold. If there is oil in the coolant tank, the car's cylinder head needs to be repaired quickly.
No matter what color your car's smoke is, if it appears in dense concentrations you need to take your car in for timely maintenance and repair.
Toxic substances in car exhaust affect humans as well as the environment. Carbon monoxide (CO):Inhaling too much of this gas will reduce the ability to absorb oxygen, cause serious tissue damage, and risk death. Carbon monoxide is the leading cause of death in gas poisoning cases with symptoms such as feeling lightheaded, headache, nausea, difficulty breathing, and slowly falling into a coma. Benzene (C6H6):Benzene is a volatile organic compound found in gasoline and vehicle exhaust. It is dangerous because it destroys the blood. It prevents the bone marrow from producing enough red blood cells, while it damages the immune system by not producing enough white blood cells. Sulfur dioxide (SO2):This colorless gas has an unpleasant odor and penetrates the respiratory tract, causing coughing and difficulty breathing. Over a long period of time, this gas can lead to asthma and other similar health conditions. Carbon black:Soot is the black gas emitted from car exhaust. It has been linked to flu, asthma, and even cancer. Carbon black also has a negative impact on the environment, as in fact, carbon black accounts for more than 25% of toxic pollution in the air. |
