When your vehicle emits black smoke, it can be a symptom of a number of different incidents.
Here are some common causes of car-related black smoke:
1. Too much fuel is sprayed
One of the main reasons why vehicles issue black smoke is because the amount of fuel provided to the engine is too much compared to the air needed to completely burn.
This often occurs when the fuel injection system is broken or the fuel control unit (ECU) is not working properly.
When the fuel spraying system is not working effectively, the fuel will not be completely burned, creating black smoke and reducing the performance of the engine.
2. Dilapidated or damaged air leak
A dirty or congested wind leak will prevent enough air to mix with the fuel before entering the engine. This makes the combustion process ineffective, leading to fuel not being completely burned, creating black smoke.
When there is not enough air to supply the engine, the ratio of fuel in the mixture is too high and the result is black smoke.
3. Turbo system broken
Vehicles using turbo engines may encounter problems if the turbo is broken or does not work properly.
Turbo helps compress air to put into the engine, providing the perfect mixture of gas and fuel for the combustion process.
When this system is faulty, the air supply to the engine will decrease, causing the fuel to not be burned, leading to black smoke.
Turbo is an important part of increasing engine performance, and when it has a problem, the engine can operate poorly and release black smoke.
4. Dirty or too much engine oil
If the engine lacks oil or the engine oil is dirty, the internal parts will not be properly lubricated, leading to friction and high temperatures. This can make the combustion process imperfect, creating black smoke.
Engine oil not only helps lubricate but also cools parts. When it is not of good quality, the engine's performance will decrease and can cause black smoke discharge.
5. Damaged fuel filter
The fuel filter is responsible for removing dirt and impurities from the fuel before it enters the engine. When this filter is stuck, fuel will not be supplied properly, causing black smoke.
Therefore, you should replace the fuel filter periodically to avoid unwanted incidents.
