Their injection pump is set too rich, and lets more diesel into the engine than the engine can burn. The partially/badly burned diesel is what comes out as black smoke.
yes
buy a chip or programmer. straight pipe your exhaust.
Under heavy acceleration all diesels produce black smoke. It's a product of waste fuel being exited via the exhaust pipe and is a sign of inefficiency. Older diesels also produce black smoke under "normal" conditions and this also a cause of unspent fuel, but mainly because of age.
Black smoke from a Duramax diesel engine typically indicates incomplete combustion, often due to an overly rich fuel-air mixture. This can result from issues like a clogged air filter, malfunctioning fuel injectors, or problems with the turbocharger. Additionally, excessive fuel delivery during acceleration or heavy loads can also cause temporary black smoke. Regular maintenance and diagnosing any mechanical issues can help mitigate this problem.
If you have black smoke coming out it would be because you have bad timings, i have a buddy who had that happen to his jeep and we replaced the spark plugs and air filter and fixed the timing and it solved the problem, but wen you blow black smoke its because of bad timing it happens with diesels to.
emissions and exhaust
buy a cummins
He is a US citizen of Italian and black ancestry
how can i get black exhaust smoke stuck on my dual exhaust
Black smoke, from any diesel, is the result of partially burned fuel. Overfueling will cause black smoke.
What can cause black sooty exhaust is bad valve guides. When the guides are bad oil leaks into the cylinder when the car isn't running. When the car starts it produces black exhaust.
You don't want your gasoline powered engine smoking black. If it does, then you have some SERIOUS mechanical problems. Black smoke is for diesels. Keep it that way!!!!
