duce black smoke in diesel engines

Diesel engines have a reputation for being dirty and making lots of black smoke. That’s one of the dominant images that people have – a diesel rig going down the highway with black smoke belching from the stacks. In the 60s and 70s and 80s, that was pretty much accepted as normal. And all that is a shame, because the diesel engine is a more efficient and better engine than a gasoline-powered engine.

The newer common-rail diesels are a big step up from the old diesel engines, enabling huge gains in horsepower and performance without the need to see lots of black smoke. The corollary to this is that if you see your diesel making black smoke, that’s an indicator that something needs to be fixed. Not only does it make you look bad, it’s bad for the environment and it will end up costing you more because black smoke means lower fuel mileage and more $$ out of your pocket. So, let’s explore how to reduce black smoke in diesel engines by looking at what causes it.

Restricted Air

Black smoke is partially-burned fuel. An engine that’s running properly will burn all of the diesel fuel completely, making CO2 and water. So black smoke means something is causing the fuel to not burn completely. Air is a critical element of the combustion process; the right amount of air is needed to completely burn the fuel. Not enough air means incomplete fuel combustion.

What can cause this restricted air condition? It could be a dirty or restricted air cleaner system.

Turbocharger Lag = Puffs of Black Smoke

Large diesels pulling heavy loads will often puff black smoke when they are getting ready to accelerate from a stop. This large diesel have huge turbochargers that take a lot of time and a lot of fuel to “spool up”. When they are waiting to getting rolling, they will “roll coal” before the light turns green, trying to get the turbocharger up to speed before they get moving. This adds a lot of fuel to an engine that’s only turning at low RPMs.

This condition only really happens with older trucks and is a design problem. There’s not much that can be done with that, apart from maybe adding a combustion catalyst to the fuel to improve the amount of that diesel burned at those low RPMs.

Incorrect fuel/air ratio or injector problems

A mechanical issue that disrupts the balance between the right amount of fuel and right amount of air being burned is going to produce black smoke. It could be as simple as adjusting the injector timing or checking the EGR system to make sure the EGR valve doesn’t need to be replaced.

If it’s not something like that, you’re looking at a mechanical problem. The valve clearances may be wrong. Or the injectors may need to be looked at. Fuel injectors are the most important element to an optimally-running diesel engine. If they’re worn or plugged, you won’t get the best atomization of the fuel, which is what the engine relies on for its best performance.

Engine Deposits Will Cause Black Smoke

Any engine runs at its absolute peak when it is new. Over time, the engine conditions change for the worse and this includes getting accumulations of combustion product combustion in critical areas like injectors and combustion chambers. And these interfere with best functioning.

Diesel engines are especially prone to this because a) they run for such a long time and b) because diesel fuel doesn’t come from the refinery with any special detergent packages already added.

The fix for this is to add a detergent additive to your diesel fuel on a regular basis. A multifunctional treatment like Dee-Zol will clean out the deposits, reduce the amount of fuel burned incompletely burned, and can even extend the life of your DPF (because less soot are being produced at any one time).

Frequently Asked Questions About how to make diesel smoke black

If you have questions that need to be answered about the topic how to make diesel smoke black, then this section may help you solve it.

How do I make my diesel emit black smoke?

Over-fueling, which can be brought on by diesel fuel injector wear that enlarges the nozzle hole or erodes the injector needle and permits excess fuel to flow into the combustion chamber, is the main factor causing black smoke to come from a heavy duty diesel engine’s exhaust.

How is black smoke made?

With flammable chemicals in the smoke, the first strategy—pushing the burn rate high to achieve partial combustion—will result in black smoke. The second strategy—burning a fuel that produces dark smoke. Most synthetics produce dark toxic smoke, which is why house fires produce black smoke.

How can black smoke from exhaust be removed?

Five fixes to get rid of black smoke coming from the exhaust

Clean Air Filters And Combustion Chamber. By now, we understand that black smoke emissions are often a result of clogged filters and buildup in the engine. …
Use Fuel Additives. …
Replace Oxygen Sensors. …
Check Piston Rings. …
Contact A Professional.

What can I do to make my diesel roll coal?

More diesel fuel is forced into the engine than it can handle during coal rolling, causing the engine to produce massive amounts of dark exhaust fumes.

Does diesel harm from black smoke?

It’s a good idea to keep an eye on the amount of black smoke at different RPMs and loads so that you will be able to tell if something is wrong. A little black smoke is normal on a properly functioning diesel. In fact, some diesel owners add larger injectors to create more black smoke.

How can I get my diesel to stop spewing out white smoke?

The use of glow plugs during cold startsand/or the use of a flushing solvent to remove engine sludge is advised. If white smoke occurs during a startup in freezing temperatures, then goes away, it typically indicates frozen deposits of soot which expanded around the rings then burned away once the engine warmed up.

Is diesel-engine black smoke a problem?

An engine that is functioning properly will burn all of the diesel fuel completely, producing CO2 and water. Black smoke indicates that something is preventing the fuel from burning completely.

Does the engine suffer from rolling coal?

Although “rolling coal” can enhance short-term engine performance, fuel efficiency will decrease, and the practice will eventually cause more harm to your engine than good.

How can I stop my diesel from whitened-smoking?

Diesel Engines Blowing White Smoke from Exhaust: Faulty Head Gaskets and Cracked Cylinder Heads or Blocks are Common Causes of Water Entry, and are Often to Blame, but Expensive Mechanical Repair is the Only Proper Solution Here Water entering combustion spaces will also create white smoke.

How quickly does diesel engine oil turn black?

Diesel oil typically turns black after several hundred miles, which is common and expected after an oil change.

Why do diesel engines with high performance smoke?

The black smoke is full of particulates, which are basically large diesel particles that normally would be burned as fuel, which means either too much fuel is being added to the mixture or there isn’t enough oxygen being supplied to burn the fuel.

Does white smoke harm a diesel engine?

When the exhaust smoke from a diesel engine vehicle is white, there is cause for concern because white exhaust smoke indicates improper fuel combustion and may indicate one of the following: an overly cold engine.

a segment of the YouTube video Why Does Diesel Oil Turn Black? Why Is Diesel Oil So Dark?

Why doesn’t my diesel oil darken?

Since carbon deposits are typically black in color, it won’t take long for the oil to turn black if there are deposits inside the engine.Deposits Can Lead to Black Motor OilThe motor oil contacts nearly everything inside the engine while it is operating, including deposits that may have formed on engine parts.

How much time does oil need to turn black?

Even if your diesel engine has very low mileage and has received new oil and filters at the recommended intervals, the oil will become SO dark that it resembles “black” within 20 to 50 miles, possibly even sooner.
