engine emissions
Combustion byproduct gases
Engine emissions are the gases and particles released when an engine burns fuel.
The term typically refers to exhaust from internal combustion engines in vehicles—carbon dioxide, nitrogen oxides, particulate matter, and other pollutants.
Environmental regulations target engine emissions to reduce air pollution and climate impact: The new standards require a 30% reduction in engine emissions by 2030.
