With the development of economy and the increase of motorized vehicles, vehicle exhaust has a serious impact on air quality. These sources are also known as mobile pollution sources. Mobile pollution sources include automobiles, ships, trains, aircraft and etc. These sources, as difficult as they are to track, have been the origin of about half of the air pollution in the United States. Therefore, mobile emissions control has become the top priority of pollution control. However, mobile sources of air pollution are the most difficult to pinpoint because they are constantly moving. Therefore, it is an ideal method to treat harmful pollutants from mobile pollution sources into benign compounds by means of catalytic converter.
Alfa Chemistry has been working in the field of environmental governance for many years. Our mobile emissions control technologies and products have been used in a lot of cars, ships and trucks around the world, helping to remove millions of tons of harmful pollutants produced by gasoline and diesel engines. Our goal is to provide cleaner air for everyone.
Know the Main Pollutants of Mobile Emissions
The major emissions from cars and other motorized vehicles include carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter.
- Carbon monoxide (CO): This is a colorless, odorless gas that causes serious, possibly fatal, health problems. Motor vehicles emit massive amounts of carbon monoxide.
- Hydrocarbons (HC): Emitted because of incomplete gasoline combustion, these combine with nitrogen oxides in the presence of sunshine to form ozone (O3) which has adverse health effects.
- Nitrogen oxides (NOx): These compounds pose problems mostly in the form of nitrogen oxide (NO) and nitrogen dioxide (NO2). The compound combines with hydrocarbons and other volatile organic compounds (VOCs) in the presence of ultraviolet sunlight to produce photochemical smog, mainly ozone (O3), which has adverse health effects.
- Particulate matter (PM10): These minuscule particles are emitted by exhausts and by mechanical wear, such as, break lining or rubber tires.
