Diesel particulate filter of a school bus A diesel particulate filter (top left) in a Peugeot Off-road – DPF installation. A diesel particulate filter (DPF) is a device designed to remove diesel particulate matter [broken anchor] or soot from the exhaust gas of a diesel engine. [1] [2]
As part of a January 2019 settlement, Fiat Chrysler recalled and repaired approximately 100,000 automobiles equipped with a 3.0-litre V6 EcoDiesel engine having a prohibited defeat device, pay $311 million in total civil penalties to US regulators and CARB, pay $72.5 million for state civil penalties, implement corporate governance reforms, and ...
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 ...
Diesel exhaust fluid (DEF; also known as AUS 32 and sometimes marketed as AdBlue [3]) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous urea solution made with 32.5% urea and 67.5% deionized water .
In July 2005, Wayne Nastri, Regional Administrator for Region 9 of the EPA, initially proposed the idea of a Diesel Emissions Reduction in the 109th Congress, 1st session. Nastri focuses on the negative health effects that diesel has on the environment. He concludes that diesel fuel, when burned, emits both nitrogen oxides and particulate matters.
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 ...
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 ...
Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, [1] or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe , flue gas stack , or propelling nozzle .
