Have you ever seen smoke coming from a vehicle's engine? Maybe you have, maybe you haven't. However, any engine emits smoke. But they may not be visible to the eye. Some other types of smoke are visible to the eye. So, as a person who owns a vehicle, as a person who is looking to buy a vehicle, or as a person who drives a vehicle, you should be aware of the smoke emitted from these engines. That's why we at MotorGuide thought we would tell you today about the types of smoke emitted from engines that are visible to the eye.

What types of smoke are emitted from an engine?

If smoke is visible from an engine, there is some kind of problem with that engine. Sometimes it means that it is time to repair the engine. Generally, there are three basic types of smoke emitted from any engine.

  • White smoke
  • Blue smoke
  • Black smoke

What is this white smoke? Smoke?

Most of the time, white smoke comes out of an engine when a small amount of oil in the engine is burning. In addition, when you buy a water-cooled vehicle, most of the time, if the head gas cut is broken and water leaks into the cylinder, this white smoke comes out even when that water is burned. When white smoke comes out of a water-cooled vehicle, it means that the radiator is low on water, which means that the head gas cut of the engine is broken. The water that leaks into the cylinder through that head gas cut is the exhaust steam that burns and comes out in white.

When some vehicles start the engine in the morning, white smoke comes out of the engine. But that is not smoke coming out because of a problem with the engine. It happens because of the cold in the morning.

When white smoke comes out of the engine of an air-cooled vehicle, it means that a very small amount of engine oil is leaking into the cylinder. The smoke that comes out when that engine oil is burned is white.

If a very small amount of engine oil is leaking from an engine, the reason for that is the valve The seal is worn out. When this happens, oil leaks into the cylinder through the valve seal. In general, if the valve seal is worn out or the valve guide is worn out, or if there are problems with the head gas cut, the cylinder may leak engine oil. The end result is white smoke coming out of the engine.

What is blue smoke?

If a large amount of engine oil is burned, then blue smoke is emitted. When a large amount of oil is burned, this blue smoke usually comes from the moment an engine is started. What happens then is that a large amount of engine oil leaks into the cylinder of the engine. When that leak occurs, that engine oil burns and comes out as blue smoke. As mentioned earlier, this is also where engine oil leaks. But basically, the cause of engine oil leaking into the cylinder is the wear of the piston rings. In addition, another thing that can happen when blue smoke is emitted is that the plug is constantly burning.

Black smoke coming out of the engine What is colored smoke?

Like the white smoke we mentioned earlier, blue smoke is also emitted due to a problem with the engine. However, if this black smoke is emitted, it is not due to a problem with the engine. However, the damage that can be caused to the engine due to the emission of black smoke is much greater.

Usually, black smoke comes from an engine after the engine has reduced the amount of gasoline unnecessarily. We call it, the carburetor is clogged with oil. Reducing the amount of gasoline means that the air fuel mixture is lean. That is, the amount of gasoline in the air fuel mixture is reduced. Then a weak air fuel mixture goes into the engine. When a lean air fuel mixture is burned in this way, black smoke often comes out. When this black smoke comes out, the engine is overheating. You should definitely know that. Because there is a chance that it will cause a mechanical failure of the engine. So if black smoke is emitted, it is a problem caused by the lean air fuel mixture in the carburetor. Therefore, the air fuel mixture You need to get it back to normal and tune the carburetor to normal. So when you see black smoke, you need to know, "This is not a problem with the engine, but if black smoke continues to come out like this, it can cause serious damage to the engine."

These are the types of smoke that are visible to the eye from the engine. We hope that this article will give you a good understanding of what causes smoke and what kind of damage some of the smoke can cause to the engine. So from now on, if any of the types of
