After a while the gases containing dirty, sooty carbons start to cover and coat the intake area and valves causing the air to fuel ratio to become unbalanced thus resulting in more black smoke being emitted from the exhaust. This black smoke is then drawn back into the air intake via the EGR valve.
What’s the best way to get smoke out of diesel?

White smoke in a VW diesel is not really any different, when compared to white smoke from an Isuzu diesel. It means the same – engine mixture, efficiency wise, is out of spec. I have seen LEAN mixtures and WATER cause this as well. But again, there can be a lot more to it. And diesel pump timing is critical.
What causes lack of power in Isuzu NRR truck?
Weak valve springs. Burned or sticking valves. Poor cylinder compression pressures. Engine brake exhaust valve stuck in closed position. Worn camshaft lobe. Intake manifold air leakage. Air leak at turbocharger turbine housing. Blocked air cleaner assembly. Blocked engine exhaust system.
What causes black smoke from a diesel engine?
Black Smoke: -Air to fuel ratio imbalance. Either the fuel system is delivering too much fuel or there’s not enough clean air available. Possible Causes: 1) Faulty injectors. (injectors may need attention, normally at 100,000 to 120,000 miles) 2) Faulty injector pump. 3) Dirty air filter/cleaner. 4) Turbocharger or intercooler faulty

What to do when a tractor is blowing black smoke and has?
This can clog up the fuel injector pump and interfere with functioning. Also, if you consistently let the fuel level get very low, the injector and pump will not have sufficient lubrication to work, and the fuel will not be delivered at the pressurized level that it should be.
Why is my diesel engine blowing black smoke?
If your fuel injector gets dirty or clogged, this can be the cause of black smoke and a loss of power. The purpose of a fuel injector is to supply your diesel engine with fuel (source). The injector sprays fuel into the engine’s cylinder via a nozzle to start the fuel combustion process.
When do you get black smoke from the exhaust?
For instance, when we look at the diesel car, most times you will get a black smoke being emitted from the exhaust is the first moment the engine is switched on.

Can a bad catalytic converter cause black smoke?

Why does my Ford Excursion have black smoke?
Last week it started pumping out quite a bit white smoke on idle/low speeds AND black smoke on acceleration. By black smoke I mean closer to dark gray/light black (it’s not rolling coal per say). filled up with new diesel the day before I first noticed any smoke (I don’t know if this has anything to do with anything but maybe a clue perhaps?)

What does it mean when you have black smoke coming from your engine?
Black smoke indicates an engine air-fuel mixture that is too rich — meaning there’s too much fuel and not enough air. This is typically caused by one or more of the following problems: Faulty fuel pressure regulator: As the name implies, this device regulates fuel pressure to the engine.

Why do I have black smoke coming from my tailpipe?
If there is a lack of of air coming into the engine, the fuel will be burnt partially then leads to black smoke from tailpipe. Fuel needs to be burnt fully as it will only emit CO2 and water, which do not cause black smoke. That is why the correct combination of fuel and air is so important if you want to avoid black smoke.
How can I get black smoke out of my exhaust?
