New Gasoline Particulate Filter (GPF) for European Light Commercial Vehicles

Gasoline particulate filters (GPF’S) use the same type of wall-flow substrates as diesel particulate filters (DPF’s) 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 muffler volume, helping to reduce backpressure, increase performance, reduce weight and save cost.

The new filter technology introduced by Tenneco, is designed for gasoline direct injection (GDI) engines to reduce particulate emissions in compliance with the Euro 6c emissions regulation, which come into effect on September 1, 2017.

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…Read More (PDF)
