EN The subject of this article is to compare the effectiveness of commercial exhaust gas aftertreatment systems such as TWC and GPF with their prototype variant, which is produced on a pilot line that allows the recovery of precious metals. What's more, the said production line allows the manufacture of components compliant with Euro IV, V and VI standards. Depending on the model of the monolith made, it is possible to reduce the consumption of precious metal raw materials by up to 20%, which should be considered a significant result. The article describes in detail the manufacturing process of metal carriers using the mentioned technology. A dynamic engine dynamometer was used for tests verifying the effectiveness of particulate filters, on which the RDE test route covering the area of the Poznan agglomeration was mapped. The tests performed are particularly important, as it should be borne in mind that according to the forecast in 2025, internal combustion engines powered by conventional fuels will account for 85% of all propulsion sources. In addition, the increasing environmental awareness of vehicle users and manufacturers requires solutions to reduce PM emissions into the atmosphere in both mass and number.
