D-CAT (Farsamada Daaweynta Shidaalka Diesel Sare)
D-CAT waxay u taagan tahay Diesel Clean Technology Advanced.
Waa nidaam si weyn u yareeya xaddiga wasakhda ee gaaska qiiqa. Ubucda tiknoolajigan ayaa ah shaandhaynta naaftada ee DPNR, taas oo aan dayactir lahayn iyo, marka lagu daro dambas, sidoo kale waxay yareyn kartaa qiiqa MAYA.x. Nidaamka ayaa si tartiib tartiib ah loo horumariyay wuxuuna hadda ku jiraa safka hore ee daaweynta gaaska qiiqa. Si loo cusboonaysiiyo filtarrada qayb ka sii wanaagsan, mudiye naafto gaar ah ayaa lagu daray kaas oo si toos ah shidaalka naaftada ugu duraya tuubada qiiqa ka hor inta aanu gelin marawaxadaha. Intaa waxaa dheer, nidaamka dib-u-nooleynta ayaa horeyba u shaqeeyaa si heersare ah, taas oo ah, haddii unugga kantaroolku uu go'aamiyo, oo ku saleysan calaamadda ka timaadda cadaadiska kala duwan, in filter DPNR uu buuxo, shidaalka naaftada ayaa lagu duraa, taas oo markaa kordhisa heerkulka gudaha shaandhada iyo gubaya waxa ku jira - dib u soo kabashada. Si loo yareeyo oksaydhyada nitrogen NOx waa shaandhaynta DPNR oo lagu kaabayo kiciyaha oksaydhka caadiga ah.
