I-Cummins B4.5 B6.7 L9 Injini Kadizili Hlangana ne-Euro VI Emission Standard

I-Cummins manje izothatha esinye isinyathelo mayelana nokulawula ukukhishwa kwe-Euro VI.Udizili ohlanzekile manje uzophendula umthethonqubo weSigaba-D oqinile, kulandela uhlelo lweminyaka emibili lokuthuthukisa kanye nokuhlola.Izinjini ze-B4.5, B6.7 ne-L9 ezinobubanzi obungu-112 kuya ku-298 kW ezifaka izicelo zamabhasi nabaqeqeshi zizodlulela ekukhiqizeni ngokugcwele ngaphambi kokuthi i-Phase-D iqale ukusebenza ngoSepthemba walo nyaka.

Izinjini ze-Euro VI Phase-D zokukhipha umoya omncane nophansi

Ama-Cummins yethule lo mqondo omusha wezinto ezikhishwayo eNgqungqutheleni Yezokuthutha Zomphakathi ye-UITP eqhubekayo eStockholm, eSweden.Izinjini ze-Euro VI Phase-D zizozuza ukukhishwa okucishe kufinyelele kuqanda.Lokhu kumelela igxathu elikhuphukayo elibheke kumithethonqubo ye-Euro VII, okungenzeka ukuthi iqale ukusebenza ngemuva kuka-2025.

Imithetho yeSigaba-D ibaluleke kakhulu ekusebenzeni kwamabhasi, njengoba igxile emikhawulweni eqinile yokulawula ukukhishwa kwe-Oxides of Nitrogen (NOx) phakathi nokusebenza kwedolobha elinesivinini esiphansi, kanye nangaphansi kwezimo zokuqalisa injini ebandayo.Ngokungeziwe ekuqinisekisweni kweseli lokuhlola ukukhishwa, imithetho yeSigaba-D idinga ukuhlolwa emgwaqweni ukuze kuthwebule isilinganiso somhlaba wangempela.Ukuhlolwa okusekelwe kumjikelezo wokusebenza okwenziwa ngabakwa-Cummins kusetshenziswa ama-Portable Emissions Measurement systems (PEMs) kubonise ukwehla ngamaphesenti angama-25 ekukhishweni kwe-NOx, uma kuqhathaniswa nezinjini zeSigaba-A lapho i-Euro VI yethulwa okokuqala ngo-2015.

U-Ashley Watton, uMqondisi wakwaCummins we-On-Highway Business Europe, uthe: "Ngokukhishwa kwe-NOx okuphansi kakhulu, imikhiqizo yethu yakamuva ye-Phase-D izosiza amabhasi ukuba athuthukise izinga lomoya futhi ahambisane nokufika kwakamuva kwe-London Ultra Low Emission Zone kanye nezinye ezihlanzekile. I-Air Zones isungulwa emadolobheni aseYurophu yonke.

Ukuze sithole isitifiketi seSigaba-D sigxile kungqondongqondo yokulawula ukungcola futhi sathuthukisa i-algorithm entsha yohlelo lokuphatha.Ngokucwenga kanye nokuhlola kabusha isofthiwe esikhathini esiyiminyaka emibili, sikwazile ukugwema ukwenza noma iluphi ushintsho lwezingxenyekazi zekhompuyutha enjinini noma ekukhipheni i-exhaust aftertreatment.

Umsebenzi wokuthuthukisa i-Phase-D udinga ukutshalwa kwezimali okukhulu kukaCummins, kodwa kusho ukuthi amakhasimende ethu agcina inzuzo yomkhiqizo ofakazelwe ngokusebenza okufanayo naleyo abayitholayo namuhla.Mayelana nokuhlanganiswa kwezimoto, lesi akusona isidingo sokwenza kabusha ukufakwa kwe-Euro VI njengoba izinjini zethu ze-Phase-D zinikeza isisombululo esingenamthungo, sokungena".

Isigaba D futhi sezinguqulo ezixubile

Isitifiketi seSigaba D sizodlulela ezinguqulweni ezivumelaniswe ne-hybrid zezinjini ze-Cummins B4.5 kanye ne-B6.7, ukusiza abakhiqizi bamabhasi kulo lonke elaseYurophu endleleni eya ekufakweni kukagesi kanye nokuqedwa kwemikhumbi.Ngokuhambisana ne-diesel-electric driveline, udizili ohlanzekile ongu-4.5- no-6.7-litre unganciphisa ukusetshenziswa kukaphethiloli kanye nokukhishwa kwe-CO2 ngamaphesenti angama-33.

Mayelana nemigqa evamile yamabhasi edizili, izinjini ze-Cummins ezinobuchwepheshe bokumisa/ukuqala nazo zizoqhubekela phambili kuSigaba-D, zonga ukukhishwa kukaphethiloli negesi ebamba ukushisa ngokucishe kuqede ukungenzi kahle kwenjini ezitobhini zamabhasi.

Ukuthuthukiswa okuqhubekayo kwe-Euro VI

Kusukela ekuqaleni kweSigaba-A kwethulwa imithethonqubo ye-Euro VI, Cummins injini generator ibone izinguquko eziqhubekayo ukuze kuhlangatshezwane neZigaba ezilandelanayo ngobuchwepheshe obuningi nobusha bokulawula ukungcola.Izinjini zamanje ze-Phase-C, ezethulwe ngo-2016, nazo zathuthukiswa ngamandla okukhipha amandla kanye ne-torque.

I-4 cylinder B4.5 enamandla afinyelela ku-157 kW ithuthukise ukusebenza kwezimoto njengoba inyuke i-torque esezingeni eliphansi ne-peak isuka ku-760 iye ku-850 Nm.I-6 cylinder B6.7 inyuse izinga eliphezulu yafinyelela ku-220 kW kanti i-torque ephezulu inyuke yafinyelela ku-1 200 Nm ku-1 000 rpm.Izinga eliphezulu lamabhasi e-L9 linyuke lisuka ku-239 laya ku-276 kW njengoba i-torque ephakeme kakhulu inyuke yafinyelela ku-1600 Nm.
