What Causes Black Smoke from a Car's Exhaust Pipe?

[EdenMarie]

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