Is It Normal for Car Exhaust to Have a Burnt Smell?

[HaleyMarie]

It is normal for car exhaust to have a burnt smell. The surface of the exhaust pipe is coated with various anti-corrosion materials, which can produce a pungent odor when heated and evaporated. Car exhaust refers to the waste gases emitted from the exhaust pipe, and it is a significant contributor to air pollution. These gases contain carbon monoxide, nitrogen oxides, and other solid particles that adversely affect human health, especially leaded gasoline, which poses even greater harm to humans. The functions of the exhaust pipe include: 1. Reducing environmental pollution: The exhaust pipe contains a purification system, with a three-way catalytic converter that effectively removes harmful gases from the exhaust; 2. Ventilation and exhaust: The car exhaust pipe operates in a cycle of intake, compression, power, and exhaust—without it, the car would not function; 3. Noise reduction: The exhaust pipe is equipped with a muffler, which helps reduce the noise produced by the car.
