Automobile Exhaust Temperatures

The exhaust components of an automobile engine carry gases from the combustion chamber of the engine out of the engine. Extreme high temperatures of exhaust gases can cause long-term damage to the components of an automobile engine.

Gases

  • When fuel is combusted inside an automobile engine, chemicals including ammonia, sulfuric acid and chlorine are carried out of the engine and into the Earth's atmosphere by the exhaust system. When operating under normal conditions, the gases emitted from an automobile exhaust system reach between 482 degrees Fahrenheit and 1256 degrees Fahrenheit.

Components

  • Automobile exhaust systems heat exhaust components to high temperatures. The components of an automobile exhaust system that are closest to the combustion chamber reach temperatures around 932 degrees Fahrenheit.

Damage

  • When an automobile engine is placed under stressful conditions, such as climbing a hill, the temperature of exhaust gases increases. If the temperature of exhaust gases reaches 1328 degrees Fahrenheit or above, the components of the automobile exhaust system can sustain damage.
