“…Toyota was the first car manufacturer company to use FWC system in the vehicle in 2003 using a diesel particulate-NO x reduction (DPNR) catalytic converter, subjected to \ 10 ppm sulphur in the diesel [21]. The DPNR is a porous ceramic filter coated with NSR catalyst constituting a noble metal (Pt) supported on c-Al 2 O 3 and an alkaline (K) or alkaline-earth metal (Ba) oxide.…”

“…A treatment system for diesel engines that combined these two after-treatment devices (NSR and DPF) was developed by Toyota and called Diesel Particulate NO x Reduction (DPNR) [31,32]. DPNR technology is based on the use of a particulate wall-flow filter coated with an NSR catalyst layer working under cyclic conditions.…”

“…Particulate filter regeneration is effective during the lean phase due to the presence of NO x and an excess of oxygen in the exhaust gas, similar to CRT technology. Soot oxidation is also claimed to occur during the rich phase [31].…”
