Cummins B4.5 B6.7 L9 Diesel Injini Sangana neEuro VI Emission Standard

Cummins yave kutora rimwe danho maererano neEuro VI emission control.Madhiziri akachena iye zvino achapindura kune wakanyanya kuomesera Phase-D mutemo, zvichitevera chirongwa chemakore maviri chekuvandudza uye bvunzo.Injini dzeB4.5, B6.7 neL9 dzine huwandu hwe112 kusvika 298 kW yemabhazi nemakombi ekufambisa dzichaenda kukugadzirwa kwakazara Phase-D isati yatanga kushanda munaGunyana wegore rino.

Injini yeEuro VI Phase-D yekudzikisa uye kuderera kwehutsi

Cummins yakaunza iyi pfungwa nyowani yekuburitsa mweya kuUITP Global Public Transport Summit iri kuitika muStockholm, Sweden.Injini dzeEuro VI Phase-D dzichawana padyo-kusvika-zero emissions.Izvi zvinomiririra danho rinowedzera rakananga kuEuro VII mirau, iyo ingangozotanga kushanda mushure me2025.

Mitemo yePhase-D inonyanya kukosha pakushanda kwebhazi, sezvo ichitarisa pakudzora miganhu yeOxides yeNitrogen (NOx) emissions panguva yakaderera kumhanya kweguta, pamwe nekutonhora kweinjini yekutanga mamiriro.Kuwedzera kune emissions test cell verification, iyo Phase-D mirau inoda pa-mugwagwa bvunzo kutora chaiwo-yepasirese kuyerwa.Duty cycle-based test yakaitwa naCummins vachishandisa Portable Emissions Measurement system (PEMs) yakaratidza kudzikiswa kwemakumi maviri neshanu muzana mukuburitswa kweNOx, zvichienzaniswa neinjini dzePhase-A apo Euro VI yakatanga kuunzwa muna 2015.

Ashley Watton, Cummins Director weOn-Highway Bhizinesi Europe, akati: "Nekushomeka kwakaderera kweNOx, zvigadzirwa zvedu zvePhase-D zvichabatsira mabhazi kufambisa mhepo uye kuenderana nekusvika kwazvino kweLondon Ultra Low Emission Zone uye zvimwe Zvakachena. Air Zones iri kugadzwa mumaguta muEurope.

Kuti tiwane Phase-D certification takatarisa pane emission control logic uye takagadzira algorithm nyowani yekutonga system.Nekukwenenzvera uye kudzokorora software mukati memakore maviri, takakwanisa kudzivirira chero shanduko yehardware kunjini kana kupera simba mushure mekurapa.

Basa rekusimudzira Phase-D raida mari yakawanda neCummins, asi zvinoreva kuti vatengi vedu vanochengeta bhenefiti yechigadzirwa chakaonekwa chine kuita kwakafanana kune avo vavanoona nhasi.Panyaya yekubatanidzwa kwemotokari, ichi hachisi chikonzero chekugadzirisa zvakare maEuro VI ekuisa sezvo edu Phase-D injini dzinopa isina musono, yekudonha-mukati mhinduro".

Phase D zvakare yemhando dzakasanganiswa

Iyo Phase D certification ichaenda kune yakasanganiswa-yakagadziridzwa shanduro dzeCummins B4.5 uye B6.7 injini, kubatsira vagadziri vemabhazi muEurope yese munzira yekuisa magetsi uye decarbonization yezvikepe.Pamwe chete nedhiziri-electric driveline, iyo 4.5- uye 6.7-lita yakachena dhiziri inogona kuderedza kushandiswa kwemafuta uye kuburitswa kweCO2 nezvikamu makumi matatu nenhatu kubva muzana.

Kune akajairwa dhiziri mabhazi anotyaira, Cummins injini dzine yekumira/yekutanga tekinoroji inoendawo kumberi kune Phase-D, kuchengetedza mafuta uye greenhouse gasi rinopisa nekubvisa kunyura kweinjini panomira mabhazi.

Kugara kukwidziridzwa kweEuro VI

Kubva pakatanga Phase-A kuiswa kweEuro VI mirau, Cummins injini jenareta yakaona shanduko dzinoramba dzichienderera mberi kusangana neMatanho anoteedzana ane yakawanda uye itsva emission control tekinoroji.Ikozvino Phase-C injini, dzakaunzwa muna 2016, dzakakwidziridzwawo nekuwedzera simba rekubuda uye torque.

Iyo 4-cylinder B4.5 inosvika ku157 kW yakabuda yakavandudza kuterera kwemotokari nekuwedzera mune zvese zviri pasi uye peak torque kubva 760 kusvika 850 Nm.Iyo 6-cylinder B6.7 yakasimudza chiyero chepamusoro kusvika ku220 kW ine peak torque yakawedzera kusvika 1,200 Nm pa1,000 rpm.Nhamba yepamusoro yebhazi yeL9 yakawedzera kubva 239 kusvika 276 kW nekukwira kwepamusoro torque kusvika 1600 Nm.
