Lub CAT C27 yog ib qho ntawm cov siv ntau tshaj plaws siab - horsepower diesel xyaw hauv cov khoom siv mining, pob zeb crushers, cov tshuab siv loj, thiab cov tshuab fais fab. Raws li thoob ntiaj teb cov kev cai emission tau nruj zuj zus, kev nkag siab yuav ua li cas C27 ua tau raws li qib emission sib txawv tau dhau los ua qhov tseem ceeb rau cov khoom lag luam thiab cov xa tawm.
1. Advanced Fuel Injection System - Lub hauv paus ntawm cov pa hluav taws xob tsawg
Emission tswj pib nyob rau hauv lub combustion chamber. C27 txo cov teeb meem me me (PM) thiab NOx los ntawm kev txhim kho cov roj txhaj tshuaj zoo:
Siab -Kev Txhaj Tshuaj Roj Hmab (HPCR lossis HEUI-II)
Kev txhaj tshuaj siab dua
Zoo atomization
Multi-stage txhaj (pre-, main, post-injection)
Kev lag luam tseem ceeb:
Kev siv hluav taws xob ntau dua ua rau cov pa luam yeeb tsawg dua, cov khoom siv tsawg dua, thiab qis dua NOx tsim.
2. Turbocharging thiab huab cua tswj txo cov pa taws pom
Lub C27 siv lub siab -flow turbocharger thiab ATAAC (Air-rau-Air Aftercooler) system. Cov kev hloov kho tshiab no pab:
Ua kom oxygen ceev
Tsawg kub combustion
Txhim kho roj efficiency
Txo cov pa luam yeeb dub thaum lub sijhawm ua kom nrawm
Kev tswj huab cua zoo dua=huv huv combustion + txo nqi roj.
3. Tom qab-Technology kho rau Tier 4 zaum kawg ua raws
Yuav kom ua tau raws li cov cai nruj tshaj plaws, Tier 4 Final C27 yog nruab nrog tag nrho tom qab - pob kho mob:
DOC - Diesel Oxidation Catalyst
Txo cov pa roj carbon monoxide thiab hydrocarbons.
DPF - Diesel Particulate Lim
Captures PM hais thiab tshem tawm los ntawm kev rov tsim dua tshiab.
SCR – Selective Catalytic Reduction
Txhaj DEF/urea los hloov NOx rau hauv nitrogen thiab dej vapor.
Kev lag luam Trend:
DPF + SCR tam sim no yog qhov kev daws teeb meem zoo tshaj plaws rau ultra- cov pa hluav taws xob tsawg hauv cov tsheb uas tsis yog - txoj kev diesel cav.
4. Intelligent ECM Control tswj kev ruaj ntseg emission
Lub C27's ECM (Engine Control Module) saib thiab kho ntau lub tshuab hauv lub sijhawm:
Lub sijhawm txhaj tshuaj
Cua - roj piv
EGR (ntawm qee qhov versions)
Cov cua kub
DPF regeneration cycles
Thaum lub cav nce mus txog qhov pib ua pa tawm, ECM tau hloov pauv roj daim ntawv qhia thiab cov cua ntws los tswj kev ua raws.
5. Cov ntsiab lus: Yuav ua li cas CAT C27 ua tiav kev ua haujlwm huv
C27 ua tau raws li cov qauv emission thoob ntiaj teb los ntawm kev sib koom ua ke:
High -kev txhaj tshuaj tshuab
Optimized turbocharging
Tag nrho tom qab-kev kho mob (DOC + DPF + SCR)
Intelligent ECM emission tswj lub tswv yim
Thaj tsam - cov kev xaiv kev teeb tsa tshwj xeeb
Hauv luv luv:
Lub CAT C27 xa cov horsepower siab thaum muab cov kev daws teeb meem emission rau ntau lub lag luam thoob ntiaj teb.
