exhausttreatment
Exhaust treatment, also called exhaust gas aftertreatment, refers to technologies and systems that reduce pollutants in exhaust gases from internal combustion engines. It encompasses catalytic converters, filters, and chemical dosing systems installed in the exhaust stream, as well as engine management strategies that minimize emissions.
The primary goals are to reduce particulate matter (PM), nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons
Key technologies include three-way catalytic converters for gasoline engines; diesel oxidation catalysts for CO and HC;
Operation and maintenance considerations involve ensuring sufficient temperature for catalyst light-off, monitoring with oxygen and NOx
Regulatory context drives exhaust treatment design. Standards such as EPA and EU emission regulations have shaped
