Homonym: exhaust (Fatigue)
Exhaust refers to the gases produced during the combustion process in engines, such as those found in cars and motorcycles. These gases are a byproduct of burning fuel, and they typically include carbon dioxide, water vapor, and other pollutants. The exhaust system in a vehicle helps to direct these gases away from the engine and out of the vehicle, ensuring efficient operation and reducing harmful emissions.
In addition to gases, exhaust can also refer to the physical system that channels these emissions. This system includes components like the exhaust manifold, catalytic converter, and muffler. Together, they work to minimize noise and filter out harmful substances before the gases are released into the atmosphere.
