What Causes Excessive White Smoke with a Burnt Smell from the Exhaust Pipe?

[DelHadley]

The causes of excessive white smoke with a burnt smell from the exhaust pipe are: 1. Clogged air filter; 2. Leaking cylinder head gasket; 3. Faulty fuel injector. The effects of a blocked car exhaust pipe include: 1. Reduced acceleration power, difficulty in increasing engine RPM and vehicle speed; 2. Frequent forced downshifting in automatic transmission vehicles; 3. Decreased engine power, exceeding emission standards; 4. Engine vibration, illuminated warning light, and frequent stalling. The functions of the exhaust pipe are: 1. Reducing environmental pollution: The exhaust pipe contains a purification system, including a catalytic converter that effectively neutralizes harmful gases in the exhaust; 2. Ventilation and exhaust: The car exhaust system operates cyclically for intake, compression, power stroke, and exhaust—without it, the car cannot function; 3. Noise reduction: The muffler inside the exhaust pipe reduces vehicle noise by diverting airflow through multiple channels, causing friction and collisions between streams to gradually decrease flow velocity, thereby lowering noise through repeated cycles.
