Overview
Black smoke is a clear sign of poor engine health and leads to many issues in the engine. Black smoke indicates engine problems and is not good for the environment and feels embarrassed on the road. If you don’t understand the cause of black smoke, no need to worry about it. We can help you to identify the reason behind this and what are the causes of black smoke from the exhaust. We simply mean the black smoke is imbalanced fuel and air ratio or maybe some serious issue in the engine. But is an avoidable point. You should notice how your vehicle running to protect the car from any incident. Usually, we didn’t notice the color of the smoke but it doesn’t matter. The noticeable point is smoke indicates an engine problem and you need to stop the car on the safe side of the road and check the problem if you have an idea or call an expert.
Causes formation of Black Smoke
Let go heading towards the reason behind the black smoke from the tailpipe. Before forwarding to the cause let you know black smoke is a fume consisting of dirt and it blows out from the tailpipe Recognize the reason behind this, notice the vapor. If there is thick and black color vapor its means the engine is running with less amount of air and burning an excessive amount of fuel. Now let’s discuss what causes the formation of black smoke.
Clogged Air Filter
The air filter sends a sufficient amount of air to the cylinder and the dust blocking the air filter blocks the process and the engine burns excessive fuel. This ultimate blockage of the air filter is caused by black smoke from the exhaust. Besides, the other reason for black smoke is when you put a heavy load on a vehicle and feel that accelerating is hard.
Damage Fuel Injectors
The fuel injector spread equal droplets of fuel in the cylinder for the smooth working of all parts. If the fuel injectors are not working well or are clogged and never close on time it can cause to inject more fuel in a certain area which is called the rich mixture area of the car. An equal amount of fuel is important to keep the working well of all parts. The block injector is also caused to cut off a sufficient amount of air.
Bad MAF Sensors
Mass Airflow Sensors are fixed to evaluate the amount of air entering the engine in return it’s measuring the amount of fuel to be injected into the cylinder. MAF works with injectors to spread the maximum amount of fuel to be dropped in a cylinder. The entire work is important for the smooth working of the engine and controls the friction.
Bad EGR Valve
EGR valve is fixed to re-circulating the exhaust gas and to control dangerous substances. EGR valve is responsible to take exhaust gas and put some of it back into the combustion chamber. When the EGR valve is damaged this process cant keep working and causes black smoke.
How to Fix Black Smoke from Exhaust
It is not difficult to understand how o fix black smoke from the exhaust. Follow the useful tips mentioned below and save your engine and money.
Clean Air System
Make sure the air system is working perfectly and provides sufficient air to the engine. The air blockage system cause of burning excessive fuel and reduce black smoke from the tailpipe. If the black smoke blows, first you should check the air system isn’t clogged. If the air system expired replace it with a new one. It’s not cost you high compared to the engine problem.
Use Rail Fuel Injection System
A rail fuel injection system is an advanced-tech injection system. This high-pressure injecting system drops fuel directly to the solenoid valves. The advanced rail fuel injection reduces the risk of black smoke from the tailpipe. The latest diesel cars come with this new fuel injection system.
Replace Mass Airflow Sensors
If the MAF sensors answer wrong information and an excessive amount of fuel is injected into the cylinder it’s time to replace it. If the damaged MAF keeps working in an engine it can not only cause black smoke but also damage the sensitive parts of the engine which could be costly to you.
Conclusion
Not only is a black smoke alert sign for a driver but the any of smoke color can cause to damage the engine parts. Engine parts are very sensitive and also costly. Keep eyes on the tailpipe to recognize the issue before it becomes big. Follow the above-mentioned precaution and replace the damaged parts on time to protect the engine and save money from big expenses.
