Cummins B4.5 B6.7 L9 Diesel Cav Tau Txais Euro VI Emission Standard

Cummins tam sim no yuav ua ib kauj ruam ntxiv ntawm Euro VI emissions tswj.Lub tshuab hluav taws xob huv tam sim no yuav teb rau cov kev cai Phase-D nruj dua, ua raws li kev txhim kho ob xyoos thiab kev sim.Lub B4.5, B6.7 thiab L9 xyaw nrog 112 txog 298 kW ntau yam rau cov tsheb npav thiab cov ntawv tsav tsheb yuav txav mus rau tag nrho cov khoom ua ntej Phase-D yuav siv rau lub Cuaj Hli xyoo no.

Euro VI Phase-D engines rau qis thiab qis emissions

Cummins tau nthuav tawm lub tswv yim tshiab emissions ntawm UITP Ntiaj Teb Kev Thauj Mus Los Hauv Ntiaj Teb uas muaj nyob hauv Stockholm, Sweden.Euro VI Phase-D engines yuav ua tiav ze-rau-zero emissions.Qhov no sawv cev rau ib kauj ruam ntxiv rau Euro VII cov cai, uas tej zaum yuav siv tau tom qab 2025.

Cov kev cai Phase-D yog qhov tshwj xeeb rau kev khiav tsheb npav, vim lawv tsom mus rau kev tswj nruj dua rau Oxides ntawm Nitrogen (NOx) emissions thaum lub sijhawm ua haujlwm hauv nroog qis, nrog rau hauv cov cua txias pib.Ntxiv nrog rau kev kuaj ntsuas hluav taws xob ntawm tes, Phase-D cov cai yuav tsum muaj kev sim ntawm txoj kev txhawm rau txhawm rau ntsuas qhov tseeb hauv ntiaj teb.Kev ntsuas lub voj voog ua haujlwm ua tiav los ntawm Cummins siv Portable Emissions Measurement systems (PEMs) tau qhia txog 25 feem pua ​​​​txo qis hauv NOx emissions, piv rau Phase-A cov cav thaum Euro VI thawj zaug hauv 2015.

Ashley Watton, Tus Thawj Coj Cummins rau On-Highway Lag Luam Tebchaws Europe, tau hais tias: "Nrog NOx emissions tsawg heev, peb cov khoom siv Phase-D tshiab kawg yuav pab cov tsheb npav txhim kho huab cua zoo thiab ua raws li kev tuaj txog tsis ntev los no ntawm London Ultra Low Emission Zone thiab lwm yam huv. Air Zones tau tsim nyob rau hauv cov nroog thoob plaws Tebchaws Europe.

Txhawm rau ua tiav Phase-D daim ntawv pov thawj peb tau tsom mus rau kev tswj cov pa phem thiab tsim cov txheej txheem tshiab rau kev tswj hwm.Los ntawm kev ua kom zoo dua qub thiab rov sim cov software dua li ob xyoos, peb muaj peev xwm zam kom tsis txhob hloov kho cov khoom siv rau lub cav lossis tso pa tawm tom qab kho.

Kev txhim kho theem-D xav tau kev nqis peev ntau los ntawm Cummins, tab sis nws txhais tau tias peb cov neeg siv khoom khaws cov txiaj ntsig ntawm cov khoom pov thawj nrog kev ua tau zoo ib yam rau cov uas lawv tau ntsib niaj hnub no.Nyob rau hauv cov nqe lus ntawm kev sib koom ua ke ntawm tsheb, qhov no tsis tas yuav rov ua haujlwm rau Euro VI kev teeb tsa raws li peb cov Phase-D xyaw muab kev daws teeb meem tsis sib haum.

Phase D kuj rau cov hybrid versions

Daim ntawv pov thawj Phase D yuav txuas mus rau hybrid-adapted versions ntawm Cummins B4.5 thiab B6.7 cav, los pab cov tuam txhab tsheb npav thoob plaws teb chaws Europe ntawm txoj kev mus rau hluav taws xob thiab nkoj decarbonization.Ua ke nrog lub tshuab hluav taws xob siv hluav taws xob, 4.5- thiab 6.7-liter huv diesels tuaj yeem txo cov roj noj thiab CO2 emissions ntau npaum li 33 feem pua.

Rau cov pa roj tsheb thauj mus los, Cummins xyaw featuring nres / pib thev naus laus zis tseem yuav txav mus rau tom ntej mus rau Phase-D, txuag roj thiab cov pa hluav taws xob hauv tsev cog khoom los ntawm kev tshem tawm lub cav idling ntawm chaw nres tsheb npav.

Kev hloov kho tas li rau Euro VI

Txij li thaum pib theem-A qhia txog Euro VI cov cai, Cummins cav generators pom kev hloov pauv tsis tu ncua kom ua tau raws li Phase ua tiav nrog ntau dua thiab tshiab emissions tswj thev naus laus zis.Tam sim no Phase-C xyaw, qhia hauv 2016, kuj tau kho dua tshiab nrog cov khoom siv hluav taws xob zoo dua qub thiab lub zog.

Lub 4-lub tog raj kheej B4.5 nrog txog li 157 kW tso zis tau txhim kho lub tsheb teb nrog kev nce hauv qhov qis kawg thiab siab kawg torque ntawm 760 txog 850 Nm.6-lub tog raj kheej B6.7 tau nce qhov ntsuas siab tshaj plaws rau 220 kW nrog lub siab tshaj plaws torque nce mus rau 1,200 Nm ntawm 1,000 rpm.Qhov kev ntsuam xyuas tsheb npav siab tshaj plaws ntawm L9 tau nce los ntawm 239 mus rau 276 kW nrog kev nce siab hauv siab txog 1600 Nm.
