What Are the Causes of Black Smoke from the Exhaust Pipe?

[BrookeLynn]

The causes of black smoke from the exhaust pipe are: 1. Poor or damaged fuel injector; 2. Low fuel injector pressure; 3. Clogged air filter or damaged air flow meter; 4. Engine misfire; 5. Cylinder leakage; 6. Engine carbon buildup; 7. Incorrect ignition timing. The exhaust pipe is part of the engine's exhaust system, which includes the front exhaust pipe and the rear exhaust pipe. The exhaust system is responsible for discharging the waste gases produced by the engine while reducing pollution and noise. It consists of the exhaust manifold, catalytic converter, exhaust temperature sensor, car muffler, and tailpipe.
