exhaust emissions

**exhaust emissions**

Exhaust emissions refer to the gases and particles released into the atmosphere from the combustion processes in vehicles, industrial machinery, and other engines. These emissions typically include harmful pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM), and volatile organic compounds (VOCs), which can contribute to air pollution and have significant environmental and health impacts. Understanding exhaust emissions is crucial for developing regulations, improving engine technologies, and promoting cleaner alternatives to reduce their negative effects on air quality and public health.
