The use of particulate filters (DPF) in Diesel engines has become in recent years the standard technology for the control of soot aerosol emissions. Once emissions reduction through the management of filtration and ...
The pressure drop across DPFs directly affects the exhaust back-pressure and fuel economy of
compression ignition engines. Pressure drop is related to the soot trapped inside the DPF, increasing
exhaust back-pressure as ...

Partiremos de una configuración habitual en motores diesel con el DPF
colocado aguas abajo de la turbina, al final de la línea de escape y buscaremos
optimizar una configuración con el mismo, aguas arriba de la turbina. ...

[EN] The implementation of tight vehicle emission standards has forced manufactures to use aftertreatment systems extensively. In addition to pollutant emissions abatement, these devices have a noticeable impact on the ...
Wall-flow particulate filters have been placed as a standard technology for Diesel engines because of the increasing restrictions to soot emissions. The inclusion of this system within the exhaust line requires the development ...
