Quick Summary

Carbon monoxide poisoning
Carbon monoxide poisoning Inhalation of automobile exhaust in enclosed spaces can lead to carbon monoxide poisoning.

Exhaust emissions are noxious gases released from an automobile's internal-combustion engine. These emissions include unburned hydrocarbons, carbon monoxide, and nitrogen oxides. To reduce these pollutants, vehicles are equipped with emission control systems.1

A key component is the catalytic converter, which uses catalysts like platinum and palladium. As exhaust gases pass through it, harmful substances are converted into less harmful ones: hydrocarbons and carbon monoxide become water vapor and carbon dioxide, while nitrogen oxides are reduced to nitrogen and oxygen. Other systems, like positive crankcase ventilation (PCV) and exhaust gas recirculation (EGR), also help manage emissions.231
