Nnyocha e mere gbasara mwepụ nke ikuku mmanụ dizel mgbe e mechara ọgwụgwọ na mwepụ nke NOX na PM. Ọtụtụ usoro nhicha dị iche iche apụtala. Teknụzụ nhicha mmanụ dizel gụnyerekarị mwepụ gas ikuku mmanụ (EGR), ihe ntụgharị oxidation catalytic (DOC), ihe nzacha mmanụ dizel (DPF), usoro mbelata catalytic (SCR), na ọnyà ammonia (ASC).
1. EGR (Mgbasa ikuku gas)Sistemụ mwepụ gas nke na-ekupụ ihe, nke na-ekewapụ akụkụ nke gas nke na-ekupụ ihe na injin ọkụ ma na-ewebata ya n'akụkụ nnabata maka ọkụ ọzọ, nwere ike imezu mmetụta nke igbochi mmepụta nke nitrogen oxides na imeziwanye akụ na ụba mmanụ ọkụ.
2.DOC (Diesel Oxidation Catalyst)bụ teknụzụ ihe na-akpali mmeghachi omume nke dizel oxidation nke na-eji ihe na-akpali mmeghachi omume nwere ọla dị oké ọnụ ahịa iji mee ka ọnụ ahịa HC, CO, NO, na mgbanwe dịkwuo elu na ihe ndị dị n'ime ikuku injin, si otú a na-ebelata ọnụọgụ HC, CO, na PM.
3.DPF (Nyocha ihe na-eme ka ihe dị n'ime mmanụ dizel)bụ ụdị nzacha etinyere na sistemụ ikuku nke injin dizel, nke a na-ejikarị ejide ihe dị n'ime ikuku ahụ.
4.SCR (Mbelata Ihe Mgbochi Nhọrọ)sistemụ bụ teknụzụ nke na-eji urea ebelata nitrogen oxides (gas na-egbu egbu) na gas ikuku na-ekupụ ka ọ bụrụ nitrogen na mmiri (nke na-adịghị emerụ ahụ).
5.ASC (Ammonia Slip Catalyst)Dịka ihe na-akpali ammonia, ụfọdụ gwongworo National VI mgbe a gwọchara ha ga-enwe sistemụ ASC, nke a na-etinye n'azụ SCR ma na-ebelata ntapụ nke ammonia (NH3) n'ime ikuku nke SCR site na oxidation catalytic.
6.POCbụ ihe na-eme ka ihe na-eme ka ihe na-egbu egbu ghara ịdị irè. Ụkpụrụ ọrụ ya bụ ịchọta ihe na-egbu egbu ma gbaa ya ọkụ site na oke okpomọkụ nke gas ikuku (250 ℃ -500 ℃) iji mezuo ebumnuche nke ibelata ihe na-egbu egbu. A na-ejikarị POC eme ihe na gwongworo dị mfe. Na mgbakwunye, enwere ike imegharị POC nke ọma, ebe DPF chọrọ ntinye aka.
