Fasahar tsarkake hayakin dizal ta ƙunshi sake zagayowar iskar gas mai fitarwa (EGR), mai canza iskar oxidation catalytic converter (DOC), matatar barbashi na dizal (DPF), tsarin rage catalytic selective (SCR), da kuma tarkon ammonia (ASC).
1. EGR (Rarraba Iskar Gas Mai Shaye-shaye)Tsarin sake zagayowar iskar gas mai fitar da hayaki, wanda ke raba wani ɓangare na iskar gas mai fitar da hayaki daga injin ƙonewa kuma yana shigar da shi cikin ɓangaren shiga don ƙarin ƙonewa, zai iya cimma tasirin hana samar da nitrogen oxides da inganta tattalin arzikin mai.
2. DOC (Mai ƙara kuzarin man fetur na Diesel)wata fasaha ce ta hada sinadarin dizal wanda ke amfani da sinadaran kara kuzari da ke dauke da karafa masu daraja don kara lalata HC, CO, NO, da kuma farashin da ke canzawa a saman barbashi a cikin shakar injin, ta haka ne ke rage yawan HC, CO, da PM.
3.DPF (Tace Mai Rage Yawan Man Fetur na Dizal)wani nau'in matattara ne da aka sanya a cikin tsarin shaye-shayen injunan dizal, galibi ana amfani da shi don kama barbashi (PM) a cikin shaye-shayen.
4.SCR (Ragewar Zaɓaɓɓen Catalytic)tsarin fasaha ce da ke amfani da urea don rage sinadarin nitrogen oxides (gas mai guba) a cikin iskar shaƙa zuwa nitrogen da ruwa (waɗanda ba su da lahani).
