Find out how Citroën's particulate filter can help to minimise environmental impact.
The particulate filter features a porous silicon carbide core to trap pollutant particles in the exhaust gases. It then burns and destroys them periodically. The filter regeneration system is managed by a control unit that also carries out self-diagnosis.
The particulate filter enhances the benefits of HDi technology in environmental protection, vehicles equipped with HDi diesel engines and the filter have near-zero particulate emissions.
