The primary reasons for black soot on the car's exhaust pipe are: 1. Spark plug failure; 2. Too low cylinder pressure in the engine; 3. Clogged air filter. The solutions for black soot on the car's exhaust pipe include: 1. Replacing the spark plug; 2. Checking the sealing of the valves and valve seats, which may require grinding or replacement with new parts; 3. Cleaning the air filter. The car's exhaust pipe is installed between the engine's exhaust manifold and the muffler, providing flexible connection for the entire exhaust system. This setup helps reduce vibration and noise, facilitates installation, and extends the lifespan of the exhaust muffler system.
