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.
Some pathways to reduce the carbon emissions of road vehicles have been considerably studied. [5] Energy use and emissions vary largely between modes, causing environmentalists to call for a transition from air and road to rail and human-powered transport, and increase transport electrification and energy efficiency.
The Clean Air Act of 1963 (CAA) was passed as an extension of the Air Pollution Control Act of 1955, encouraging the federal government via the United States Public Health Service under the then-Department of Health, Education, and Welfare (HEW) to encourage research and development towards reducing pollution and working with states to establish their own emission reduction programs.

For instance, 30% of “heavy-heavy-duty vocational” trucks would need to be zero-emission by 2032, the EPA said, while 40% of short-haul “day cabs” would need be zero emission vehicles.
The Environmental Protection Agency proposes new cuts to heavy vehicle emissions, targeting those chemicals that produce lung-damaging smog. Biden's EPA proposes new rule to reduce smog from ...
SCR systems are now the preferred method for meeting Tier 4 Final and EURO 6 diesel emissions standards for heavy trucks, cars and light commercial vehicles. As a result, emissions of NOx, particulates, and hydrocarbons have been lowered by as much as 95% when compared with pre-emissions engines. [2]
Oxidation of hydrocarbons (unburnt and partially burned fuel) to carbon dioxide and water: C x H 2x+2 + [(3x+1)/2]O 2 → xCO 2 + (x+1)H 2 O (a combustion reaction) The two-way catalytic converter is widely used on diesel engines to reduce hydrocarbon and carbon monoxide emissions. They were also used on gasoline engines in American and ...
