Mobile emissions control products and services

Mobile emission controls: many diesel particulate filter (DPF) systems incorporate an oxidation catalyst, either as a coating on the filter or as a separate element.

Mobile emission controls: a diesel particulate filter (DPF) removes particulate matter from diesel exhaust by physical filtration.

Mobile emission controls: Johnson Matthey's Three Way Filter (TWF®) technology can reduce particle numbers by 50 ‐ 90% on gasoline direct injection engines.

Mobile emission controls: nitrogen oxide can be removed from a lean gas stream by chemical adsorption onto a catalyst, hence the term nitrogen oxide adsorber catalyst (NAC). The process of adsorption releases carbon dioxide.

Mobile emission controls: the SCRF® system integrates Selective Catalytic Reduction (SCR) with a soot filter – the next step for diesel nitrogen oxide control.

Mobile emission controls: the SCRT® system is more than simply a combination of a CRT® system and an SCR system.

Mobile emission controls: selective catalytic reduction (SCR) systems work by chemically reducing nitrogen oxide to nitrogen.

Mobile emission controls: three-way catalysts for cars, vans, light trucks and motorcycles.
