As you probably know, modern diesel cars and trucks are great pieces engineers are lightweight, powerful and easy to use the also offers good fuel economy, and that’s all well and good until something like this happens.
Black smoke clouds come out from the exhaust when the vehicle is stationary or when you accelerate while driving the not only looks bad, it’s also not good for the environment and other drivers plus, black smoke from exhaust is a sign something is wrong engine, so in this article we will learn why a diesel engine produces black smoke and what are causes block smoke and how to fix it.
How is Diesel Engine Work? (Diesel Engine Function)
For causes and fixes, we need to briefly explain how diesel engines apparently work. The has many similarities with its petrol counterparts, including piston valves and many other mechanical components. One of the differences is the diesel engine. There is no spark plug to ignite the mixture in the, but fresh air enters the cylinder.
The is stalled at high power by the piston and then the fuel injection pump. fills the fuel into the cylinder, where it ignites and causes a fire The diesel engine does not need to be plugged in, another important difference is the speed of the diesel engine. In gasoline vehicles, is checked when the engine body suitable for this diesel engine is found.
The relies solely on fuel injection to regulate its speeds very simply The’s petrol engine starts quickly and shifts up when it produces too much black smoke. Exhaust fumes from a diesel car, the engine is most likely rich, this can happen when the engine fails not getting enough air if too much fuel is pumped into the cylinders or something shuts off air fuel mixture and now, we will read the most likely causes.
Causes Of Black Smoke from Exhaust
- Dirty Engine Filter
- Bad MAF Sensor
- Carbon Buildup
- Clogged Fuel Filter
- EGR System
- Fuel Injectors
- DPF Filter Regeneration
1) Dirty Engine Filter
This is where the air filter comes into play, at the beginning of the workplace. it serves as a dam removing dust dirt and other particles from the Airstream that goes towards the engine and with time these contaminants will create buildups on the filter surface consequently obstructing airflow in a diesel engine a dirty air filter may cause clouds of black smoke from the exhaust.
During accelerations this is because there is not enough fresh air to go with the extra fuel injected when you put your foot down other symptoms aside from black smoke include a lack of power sluggish acceleration and poor fuel economy if experiencing all this you should take the engine air filter out and inspect it if it looks dirty and clogged replace it.
To ensure Optimum performance on average air filters only cost between 10 and 75 dollars and changing it is something you can do on your own as it only takes a few minutes. The air filter should be changed as a part of your regular maintenance check your owner’s manual to find out how often should this be done but most car makers recommend every 12 to 15 000 miles.
2) Bad MAF Sensor
A modern diesel engine has a mif sensor is an abbreviation for mass air sensor, whose job is to accurately measure air mass they will use this information and adjust the fuel injection together with the vehicle’s ECU It works fine but the MIF sensor may be faulty or the sensor sending incorrect data may have been disabled this function also provides less air-oil mixture when more fuel is needed.
The injected will not burn completely causing a bad MF sensor with black smoke usually activates a check engine light. This means that a fault code is registered in the car. memory, but in most cases, it will just be dirty and can be sold with a simple cleaning, if a new mif sensor is needed it will cost you between $150 and $300 depending on what.
On cars you still need to replace the MF sensor. This is usually a simple job you can do yourself. In most cases you will need to remove the cable and loosen a terminal or two. complete carbon fiber parts can be installed in the engine of an old or new car.
3) Carbon Buildup
If this has been largely neglected in the past, it can restrict airflow and hinder the combustion process. The results in reduced performance and unfortunately produces black smoke from the exhaust in most cases. This carbon build-up can often be removed by using suitable additives if necessary. No miracle worker who can create miracles by melting can fill the engine from death units of carbon were collected over the years.
Make sure you choose one It is best to add added diesel fuel such as Molly’s or Lucas water to the oil. Its price is between 10 to 20 rupees and it is not expensive just because it is cast the petrol is also easy to use, but you’ll need to read the instructions to find out which bottles to use and what much water to add to the previous steps.
Another part of the oil mixture that we must not forget is the part of the air and diesel receiver that is injected into the fuel system of the cylinder. Whose task was to supply this oil in bulk Episode and some of these can be challenging but obviously you want to start there the first simple thing is the fuel filter which you can find somewhere.
4) Clogged Fuel Filter
A dirty and clogged engine compartment can cause all kinds of injection problems. Black smoke is one of them, so if you don’t know when the fuel filter was last changed, this could be the case. It’s a good idea to buy a new one, with prices ranging from $20 to $50, depending on the car’s fuel. Filters are inexpensive and replacement is generally a simple job.
5) EGR System
This is the abbreviation for gas recirculation of partial emission control device The gas burner returns to the intake only occasionally to make the car more manageable, especially in diesel engines, EGR controls the flow of gas in the system can be hard due to carbon buildup. When this happens, you will see a lot of black smoke coming out.
High speed fatigue may occur if you close the EGR valve and other components. Cleaning the is not a difficult job, we have fuel injectors and the pub that feeds them with.
6) Fuel Injectors
Diesel is highly compressed and must be in good condition or it will not burn will not be good. The most common problem is dirt accumulation in front of the injector.
Here affecting their ability to inject enough oil into the cylinders for the repair ways to get estimates compared to DIYers and pros This isn’t a cheap job either, as all prices are usually in the thousands of dollars. Most modern cars use a DPF filter in place of. diesel filters.
7) DPF Filter Regeneration
This honeycomb filter sits inside the exhaust pipe where it catches suit and other unburned particles but with time it would get clogged up which would obstruct the flow of exhaust gases to prevent this from happening car makers have developed a procedure called DPF regeneration during which extra fuel is added during the combustion process which then Burns off the accumulated particles inside the DPF filter this however should only happen in certain situations such as when cruising.
on the highway some drivers not aware of this feature may get alerted by excessive smoke pull over and turn off the engine this however stops the Regeneration process which will then again restart when the conditions are right so if you see a lot of black smoke and a message on your dashboard saying something about regeneration just keep on driving, I really hope these tricks.
