Future emissions regulations without compromising vehicle performance or durability.
Diesel Particulate Filters for original equipment applications remove particulate matter from engine exhaust gases in a closed system. When gases carrying particulate matter flow through the filter’s substrate walls, particulate matter is trapped and collected in the filter. A regeneration process, triggered by the engine management system, then burns off the soot using either a fuel borne additive or a catalytic filter coating.
Gasoline particulate filters use the same type of wall-flow substrates as diesel particulate filters and can be included in the exhaust system in addition to the series three-way catalyst or the catalyst coating can be directly applied to the filter substrate to form a four-way catalyst. Improvements in the acoustic function of the gasoline particulate filter make it possible to reduce exhaust volume, helping to reduce backpressure, increase performance, reduce weight and save cost.
