Ubushakashatsi ku bijyanye no gutunganya imyuka iva muri moteri ya mazutu nyuma yo kuyitunganya bushingira ku gukuraho NOX na PM. Kandi hari ingamba nyinshi zo kuyisukura. Ikoranabuhanga ryo gutunganya imyuka iva muri mazutu rigizwe ahanini no kuzenguruka imyuka iva muri moteri (EGR), guhindura imyuka iva muri oxidation catalytic converter (DOC), kuyungurura uduce duto twa mazutu (DPF), uburyo bwo kugabanya imyuka iva muri moteri ya mazutu (SCR), na amoniya escape trap (ASC).
1.EGR (Guhindura imikorere y'umwuka usohoka)Sisitemu yo kugarura imyuka isohora umwuka, itandukanya igice cy'imyuka isohora umwuka na moteri itwika ikayishyira mu ruhande rw'ingufu kugira ngo ikomeze gutwika, ishobora kugira ingaruka zo kugabanya ikorwa rya azote oxyde no kunoza uburyo lisansi ikoreshwa.
2.DOC (Imashini igabanya ubushyuhe bwa mazutu)ni ikoranabuhanga rya lisansi rikoresha lisansi ikoresha lisansi irimo ibyuma by'agaciro kugira ngo irusheho gukurura HC, CO, NO, n'ibiciro bihindagurika ku buso bw'ibice biri mu moteri isohora umwuka, bityo bigabanye ingano ya HC, CO, na PM.
3.DPF (Akayunguruzo ka mazutu)ni ubwoko bwa filter ishyirwa muri sisitemu yo gusohora imyuka ya moteri za mazutu, ikoreshwa cyane cyane mu gufata uduce duto (PM) mu byuka.
4.SCR (Kugabanya Kataletiki Ihitamo)sisitemu ni ikoranabuhanga rikoresha urea kugira ngo rigabanye neza okiside za azote (imyuka y’uburozi) mu mwuka usohoka mu kirere bikayihindura azote n’amazi (ibyo ntacyo bitwaye).
5.ASC (Igikangurambaga cya Ammonia Slip)Kataloge yo gutoroka ya amoniya, amakamyo amwe na amwe yo mu bwoko bwa National VI nyuma yo kuvurwa azaba afite sisitemu ya ASC, ishyirwa inyuma ya SCR kandi ikagabanya kuva kwa amoniya (NH3) mu mwuka wa SCR inyuma binyuze mu gutwika kataloge.
6.POCni oxidizer igabanya ubushyuhe bw'ibyuka biva mu kirere. Ihame ry'imikorere ni ugufata ibintu bigabanya ubushyuhe no kubitwika binyuze mu bushyuhe bwinshi bw'imyuka isohora umwotsi (250 ℃ -500 ℃) kugira ngo intego yo kugabanya ibintu bigabanya ubushyuhe. POC ikunze gukoreshwa ku modoka nto. Byongeye kandi, POC ishobora kongera kuvugururwa, mu gihe DPF isaba ubufasha bw'intoki.
