Vehicle emissions control - Wikipedia
网页Vehicle emissions control is the study of reducing the emissions produced by motor vehicles, especially internal combustion engines. The primary emissions studied include hydrocarbons, volatile organic compounds, carbon monoxide, carbon dioxide, nitrogen oxides, particulate matter, and sulfur oxides. Starting in the 1950s and 1960s, various ...
What Is An Emission Control System - How It Works? - Carorbis
网页2021年9月2日 · The emission control system includes a series of functions that the vehicle performs to keep the emissions as low as possible. Harmful emissions like carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxide (NOx) are minimised with the help of an emission control system.
