Why Do I Have Black Exhaust Smoke Coming From My Cummins ISB?
Black smoke is most commonly associated with failing fuel injectors. This occurs when the air-to-fuel ratio is not balanced, and there’s too much fuel or not enough oxygen.
If you have black smoke, your truck is not getting the fuel mileage that it should. Simple as that.
If there’s a mechanical fault in your engine, and you don’t get enough air, combustion won’t be able to occur properly. Improper burning means the fuel doesn’t burn completely, resulting in that thick black smoke coming out of your exhaust.
