Diesel engines are frequently thought of as noisy and dirty. While black smoke could appear to be a normal event with these engines however, it’s not a normal occurrence. There’s no reason to be concerned if you notice black smoke coming from your diesel engine, since the majority of the causes are simple solutions.
We examine the top four causes that smoke can occur. We also discuss methods to reduce the black smoke that comes from diesel engines.
1. Replace the Air Filter

The first thing you need to do if you wish to cut down on black smoke coming from the diesel engine, is to examine the air filter, and replace it in the event that it’s dirty.
Smoke from black is an evident sign of the fact that fuel is burning in a small portion of the chamber of combustion. When the diesel engine is functioning, it burns the fuel CO2 and water remains in the combustion chamber. Check out the Toyota sienna 2009 price in Nigeria. The black smoke indicates that something is blocking the fuel from fully burning usually due to an imbalanced ratio of air to fuel.
The first thing to check is the air mix that is entering the combustion chamber. The simplest fix is to change the engine’s air filter, which could be blocked. If there’s no air that is going into your engine, then the ratio of air to fuel will run high and leave the fuel that was not burned off.
Signs of a Clogged Air Filter
Apart from the black smoke that emanates from the diesel vehicle you may also be experiencing other signs. The imbalance can cause a loss of power, particularly in acceleration, or when you push the motor to the limit.
If the engine isn’t functioning properly it will result in an increase in the fuel efficiency. It is possible to take the air filter off and examine it. If it is filthy and blocked, you should change it to ensure better performance.
Cost to replace the Air Filter
A typical air filter costs between $10 to $75. Changing the air filter is something that you can perform on your own and takes only just a few minutes.
2. Clean or replace the MAF Sensor
Sensors for Intake and Maf
Another factor that may cause a problem with the ratio of fuel to air is a malfunctioning MAF sensor.
If the MAF sensor malfunctions it may be reading the incorrect amount of airflow that is entering the system, leading to the fuel system to add more to the system than is needed. What you end up with are black smoke from burned fuel, and extractor fan prices in Nigeria.
If you’re lucky, it’s often enough to scrub the MAF sensor thoroughly using the help of an electronic cleaning agent. However, you must be extremely careful to ensure that you don’t damage the sensor.
The Signs of a Poor MAF Sensor
Usually, whenever the MAF sensor is damaged it is when The “Check Engine Light comes on. It should be possible to identify the problem codes using an OBDII scanner.
But, you may see black smoke coming from the exhaust, or you may have difficulty getting your car to accelerate. A defective mass airflow sensor may cause an unsteady idle, low performance and fuel economy, as well as a hard start.
Labor is only approximately $45-$70 of the replacement cost. It’s not too difficult to replace many MAF sensors by yourself with a few basic knowledge of mechanics.
3. Use Diesel Additive
The last option to eliminate black smoke could be the most straightforward solution, but it’s not capable of solving all your engine issues.
But, you must ensure that you use a top quality diesel additive such as Liqui Moly or Lucas.
The Engine May Need an Additive for Diesel
Diesel additives can be useful to do more than solving the black smoke issue.
For instance, you could decide to apply an additive to your fuel prior to winter to help stabilize the fuel. You could also choose one that contains detergents to make your engine cleaner that will help prolong its life.
Cost of Diesel Additif
Most diesel-based additives cost less than $15 per bottle.
The most appealing thing about the use of diesel fuel additives is that it’s easy to utilize. You just need to pour the contents from the bottle into your tank of fuel when you are filling it up. The additive should reduce the amount of black smoke, and also helps to ensure that your diesel engine is in top state of repair.
4. Inspect the Fuel System

The second component of the air-fuel mix is the diesel that is the fuel itself. It is composed of many parts that could be responsible for the problem. You should take a look at the most obvious and simple parts first.
Begin by replacing your fuel filter EGR mechanism or timing of the injector. It is also possible that a blocked injector may be at fault. If a cleaner for the fuel injector isn’t working, you’ll have to replace the injector.
The most effective way to regulate the system that controls fuel is to check the trouble codes using the help of an OBD2 scanner. Modern diesel engines regulate everything electronically, and typically they will inform you when something is wrong in the fuel system too.
Signs of a poor Fuel Delivery
If the diesel engine is getting the incorrect amount of fuel there could be black smoke coming out of the exhaust. Additionally, you could be able to notice a rough idle as well as an overall poor performance.
Furthermore, the vehicle is likely to have a lower efficiency of fuel because the engine isn’t operating at its maximum. It’s possible that you can feel the smell of fuel if it’s not burning correctly.
Cost to repair Diesel Fuel System
The cheapest repair could be to change the filter in your car. On average, a new fuel filter costs between $50-$100 for components.
