Cummins B4.5 B6.7 L9 Diesel Engine Kukumana ndi Euro VI Emission Standard

Cummins tsopano atengapo gawo lina pankhani ya kuwongolera mpweya wa Euro VI.Madizilo oyeretsedwa tsopano ayankha ku malamulo okhwima a Phase-D, kutsatira ndondomeko ya zaka ziwiri ya chitukuko ndi mayeso.Ma injini a B4.5, B6.7 ndi L9 omwe ali ndi mphamvu ya 112 mpaka 298 kW pamabasi ndi makochi ayamba kupanga zonse Phase-D isanayambe kugwira ntchito mu September chaka chino.

Injini za Euro VI Phase-D zotsika komanso zotsika

Cummins adayambitsa lingaliro latsopanoli la mpweya wabwino pa msonkhano wa UITP Global Public Transport Summit womwe ukuchitikira ku Stockholm, Sweden.Ma injini a Euro VI Phase-D apeza mpweya wapafupi ndi ziro.Izi zikuyimira gawo lowonjezera ku malamulo a Euro VII, omwe mwina ayamba kugwira ntchito pambuyo pa 2025.

Malamulo a Phase-D ndi ofunikira makamaka pamabasi, chifukwa amayang'ana kwambiri malire oletsa kutulutsa kwa Oxides of Nitrogen (NOx) panthawi yocheperako m'mizinda, komanso poyambira injini yozizira.Kuphatikiza pa kutsimikizira kwa maselo otulutsa mpweya, malamulo a Phase-D amafunikira kuyesa kwapamsewu kuti ajambule muyeso wapadziko lonse lapansi.Kuyesa kwapang'onopang'ono kochitidwa ndi Cummins pogwiritsa ntchito ma Portable Emissions Measurement systems (PEMs) kwawonetsa kuchepa kwa 25 peresenti ya mpweya wa NOx, poyerekeza ndi injini za Phase-A pomwe Euro VI idayambitsidwa koyamba mu 2015.

Ashley Watton, Mtsogoleri wa Cummins wa On-Highway Business Europe, adati: "Ndi mpweya wochepa kwambiri wa NOx, zinthu zathu zaposachedwa za Phase-D zithandizira mabasi kuwongolera mpweya wabwino ndikugwirizana ndi kubwera kwaposachedwa kwa London Ultra Low Emission Zone ndi zina Zoyera. Ma Air Zones akukhazikitsidwa m'mizinda ku Europe.

Kuti tikwaniritse chiphaso cha Phase-D tidayang'ana kwambiri zowongolera mpweya ndikupanga njira yatsopano yoyendetsera kasamalidwe.Mwa kuyenga ndi kubwereza pulogalamuyo kwa zaka ziwiri, tinatha kupeŵa kusintha kwa hardware ku injini kapena kuthamangitsidwa pambuyo pake.

Ntchito yachitukuko cha Phase-D idafuna kuti Cummins ikhale ndi ndalama zambiri, koma zikutanthauza kuti makasitomala athu amapeza phindu lachinthu chotsimikizika chomwe chimagwira ntchito mofanana ndi zomwe amakumana nazo masiku ano.Pankhani ya kuphatikizika kwa magalimoto, izi siziyenera kukonzanso makina a Euro VI monga ma injini athu a Phase-D amapereka njira yosasunthika, yotsitsa ".

Phase D nawonso mitundu yosakanizidwa

Chitsimikizo cha Phase D chidzafikira ku mitundu yosakanizidwa ya injini za Cummins B4.5 ndi B6.7, kuti zithandize opanga mabasi kudutsa ku Ulaya panjira yopita ku magetsi ndi kutulutsa mpweya wa zombo.Pamodzi ndi dizilo-magetsi amagetsi, dizilo zoyera za 4.5- ndi 6.7-lita zitha kuchepetsa kugwiritsa ntchito mafuta komanso mpweya wa CO2 ndi 33 peresenti.

Pamayendedwe wamba a mabasi a dizilo, ma injini a Cummins okhala ndi ukadaulo woyimitsa/woyambira nawonso apita patsogolo ku Phase-D, kupulumutsa mafuta ndi mpweya wotenthetsera mpweya pochotsa kuyimitsa kwa injini pamalo okwerera mabasi.

Kusintha kwa nthawi zonse kwa Euro VI

Kuyambira Phase-A yoyamba kukhazikitsidwa kwa malamulo a Euro VI, Cummins injini jenereta adawona kusintha kosalekeza kuti akwaniritse Magawo otsatizana ndiukadaulo wochulukirapo komanso watsopano wowongolera mpweya.Ma injini a Phase-C apano, omwe adayambitsidwa mu 2016, adasinthidwanso ndikuwonjezera mphamvu ndi torque.

4-silinda B4.5 yokhala ndi mphamvu yofikira ku 157 kW inathandiza kuti magalimoto azitha kuyankhidwa bwino ndikuwonjezeka kwa torque yotsika komanso yotsika kwambiri kuchoka pa 760 mpaka 850 Nm.6-silinda B6.7 inakwera pamwamba kufika 220 kW ndi torque yapamwamba yowonjezereka mpaka 1,200 Nm pa 1,000 rpm.Mabasi apamwamba kwambiri a L9 adakwera kuchoka pa 239 mpaka 276 kW ndikukwera kwa torque mpaka 1600 Nm.
