Cordierite Diesel Particulate Filter on GM 7.8 Isuzu. Unlike a catalytic converter which is a flow-through device, a DPF retains bigger exhaust gas particles by forcing the gas to flow through the filter material before exiting; [2] [29] however, the DPF does not retain small particles. Maintenance-free DPFs oxidise or burn larger particles ...
Diesel exhaust is the exhaust gas produced by a diesel engine, plus any contained particulates. Its composition may vary with the fuel type, rate of consumption or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator ...
Early in the 1950s scientists discovered that vehicle emissions were a significant factor that had been causing the air quality to deteriorate. [7] This led to the introduction of vehicle emissions standards in California in 1966, furthermore due to the seriousness of the problem, in 1970 the Clean Air Act was introduced in order to regulate these standards all over the United States.

California Attorney General Rob Bonta and the California Air Resources Board (CARB) entered a $25 million settlement with Bosch for its role in the diesel emissions cheating scandals at Volkswagen ...
The complaint, seeking up to $46 billion in penalties for Clean Air Act violations, [298] alleged that Volkswagen equipped certain 2.0 and 3.0-litre diesel-engine vehicles with emissions cheating software, causing NO x pollution to exceed EPA's standards during normal driving conditions. It further claimed that Volkswagen entities provided ...
The National Clean Diesel Campaign focuses on the health of Americans due to the exhaust emissions from diesel engines; specifically nitrogen oxides and particulate matter. It includes regulations for new diesel engines, voluntary programs for the existing diesel fleet, diesel emission reduction technologies and strategies, and current ...

Catalytic converters remove only 20–40% of PM so particulates are cleaned up by a soot trap or diesel particulate filter (DPF). In the U.S., all on-road light, medium, and heavy-duty diesel-powered vehicles built after 1 January 2007, are subject to diesel particulate emission limits, and so are equipped with a 2-way catalytic converter and a ...
