Mercedes-Benz inozivisa tekinoroji yeBluetec
Mercedes-Benz iri kuita bhuruu kuita girinhi ichishandisa tekinoroji yeEuropean-approved Selective Catalyst Reduction (SCR), kana kuti Bluetec sekudanwa kwairi kuitwa neMercedes-Benz, kutevedzera mutemo mutsva we2008 wekuburitsa mweya.
SCR, pamwe chete neExhaust Gasi Recirculation (EGR), ndeimwe yematekinoroji maviri akajairika ari kushandiswa nevagadziri vemarori pasi rese kusangana nemirau mitsva yekuburitsa mweya.
Inowanzoonekwa senzira iri nyore yekuzadzisa chinangwa chekupedzisira chekudzikisa emission pane EGR nekuti iri nyore tekinoroji isingade chero shanduko kune base injini sezvinoita EGR.
Pane kudaro, iyo SCR inobaya Adblue, yekuwedzera-yakavakirwa mvura, murukova rwekupera. Izvi zvinoburitsa ammonia, inoshandura NOx inokuvadza kuita nitrogen nemvura.
Iyi inzira yekunze-ye-cylinder, nepo EGR iri in-cylinder nzira yekupedza kuchenesa, izvo zvinoda shanduko huru kune injini pachayo.
Mabhenefiti eSCR ndeokuti injini inogona kumhanya yakasviba, sezvo chero humwe hutsi hunogona kucheneswa murukova rwekupera mushure mekunge vasiya injini.
Izvi zvinobvumira vagadziri veinjini kuti vagadzirise injini kuti iwedzere simba uye hupfumi hwemafuta huri nani pasina kudzikiswa nekudiwa kwekuchenesa injini pachayo. Nekuda kweizvozvo, injini dzeMercedes-Benz dzakadzokororwa dzine reshiyo yepamusoro yekumanikidza uye inoburitsa makumi maviri emabhiza kupfuura injini dzazvino.
Iyo SCR injini inomhanya zvakare inotonhorera, saka hapana chikonzero chekuwedzera huwandu hweiyo yerori yekutonhodza system, sezvazvakaita neEGR, izvo zvinoita kuti injini inopisa zvakanyanya.
Kune anoshanda, izvi zvinoreva kugadzirwa kwepamusoro uye kuderera kwemari yekushandisa.
Vazhinji vashandisi vakawana mukana wekuyedza imwe yemarori akawanda ebvunzo akaongororwa muAustralia nevagadziri vachishandisa iyo SCR zano - Iveco, MAN, DAF, Scania, Volvo uye UD - taura kuita zvirinani uye kubata kwemarori matsva zvichienzaniswa neapfuura. . marori avo, uye vazhinji vanoti vakavandudza hupfumi hwemafuta.
Izvo zvakaderera kune vashandisi ndezvekuti vanofanirwa kuvhara mari yekuwedzera yeAdblue, iyo inowanzowedzerwa pamwero we3-5%. Adblue inotakurwa mune imwe tangi pane chassis. Iyo inowanzo kuve neinokwana 80 litres, iyo yaikwana kuwana B-kaviri kuenda nekubva kuBrisbane neAdelaide mukuedzwa kwazvino kwakaitwa neVolvo.
Mercedes-Benz ine marori matanhatu ane SCR ari kuongororwa munharaunda, anosanganisira marori maviri eAtego, imwe Axor tirakita uye matatu Actros matirakita. Vese vanoiswa pasi pekuvheneka mune mamwe mafomu akaomarara munyika kuti vaone kuti vakagadzirira zvakakwana kuunzwa kwemitemo mitsva muna Ndira.
