Mercedes-Benz imayambitsa ukadaulo wa Bluetec
Mercedes-Benz ikusintha buluu kukhala wobiriwira pogwiritsa ntchito ukadaulo wovomerezedwa ndi European Selective Catalyst Reduction (SCR), kapena Bluetec momwe Mercedes-Benz imayitanira, kuti igwirizane ndi malamulo atsopano a 2008 otulutsa mpweya.
SCR, pamodzi ndi Exhaust Gas Recirculation (EGR), ndi imodzi mwa matekinoloje awiri omwe amagwiritsidwa ntchito ndi opanga magalimoto padziko lonse lapansi kuti akwaniritse malamulo okhwima atsopano otulutsa mpweya.
Nthawi zambiri imawoneka ngati njira yosavuta yopezera cholinga chochepetsera mpweya kuposa EGR chifukwa ndiukadaulo wosavuta womwe sufuna kusintha kulikonse pa injini yoyambira monga EGR imachitira.
M'malo mwake, SCR imabaya Adblue, chowonjezera chochokera kumadzi, mumtsinje wotulutsa mpweya. Izi zimatulutsa ammonia, omwe amasintha NOx kukhala nayitrogeni wopanda vuto ndi madzi.
Iyi ndi njira ya kunja kwa silinda, pamene EGR ndi njira ya in-cylinder yoyeretsa utsi, yomwe imafuna kusintha kwakukulu kwa injini yokha.
Ubwino wa SCR ndikuti injini imatha kuyenda movutirapo, chifukwa zotulutsa zilizonse zimatha kutsukidwa mumtsinje wotuluka pambuyo posiya injini.
Izi zimalola opanga injini kuti asinthe injini kuti ikhale ndi mphamvu zambiri komanso mafuta abwinoko popanda kuchepetsedwa ndi kufunikira koyeretsa injiniyo. Zotsatira zake, injini za Mercedes-Benz zomwe zidasinthidwanso zimakhala ndi chiŵerengero chapamwamba cha kuponderezana ndipo zimapanga mahatchi 20 kuposa injini zamakono.
Injini ya SCR idzakhalanso yozizirirapo, kotero palibe chifukwa choonjezera kuchuluka kwa kuzizira kwa galimotoyo, monga momwe zimakhalira ndi EGR, zomwe zimapangitsa injiniyo kutentha kwambiri.
Kwa wogwiritsa ntchito, izi zikutanthauza zokolola zapamwamba komanso zotsika mtengo zogwirira ntchito.
Ogwira ntchito ambiri omwe adakhala ndi mwayi woyesa imodzi mwa magalimoto oyesera omwe amayesedwa ku Australia ndi opanga pogwiritsa ntchito njira ya SCR - Iveco, MAN, DAF, Scania, Volvo ndi UD - lipoti la ntchito yabwino ndi kasamalidwe ka magalimoto atsopano poyerekeza ndi zakale. . magalimoto awoawo, ndipo ambiri amati mafuta akuyenda bwino.
Choyipa kwa ogwira ntchito ndikuti amayenera kulipira ndalama zowonjezera za Adblue, zomwe nthawi zambiri zimawonjezeredwa pamlingo wa 3-5%. Adblue imatengedwa mu thanki ina pa chassis. Nthawi zambiri imakhala ndi mphamvu pafupifupi malita 80, zomwe zinali zokwanira kutenga B-double kupita ndi kuchokera ku Brisbane ndi Adelaide pamayeso aposachedwa a Volvo.
Mercedes-Benz ili ndi magalimoto asanu ndi limodzi okhala ndi SCR omwe akuwunikiridwa komweko, kuphatikiza magalimoto awiri a Atego, thirakitala imodzi ya Axor ndi mathirakitala atatu a Actros. Onsewa akuyikidwa pansi pa blowtorch m'mafunso ovuta kwambiri mdziko muno kuti awonetsetse kuti ali okonzekera kukhazikitsidwa kwa malamulo atsopano mu Januware.
