Umbono oyiphutha: "Imoto enenjini kadizili ingcolisa ngaphezu kwemoto enenjini kaphethiloli."
Izimoto zikadizili zakha cishe izingxenye ezintathu kwezine zemikhumbi yezimoto zaseFrance. Irekhodi laseYurophu! Kodwa eminyakeni yamuva, ngokusho izinhlawulo zemvelo namahlazo afana ne-Dieselgate, izinjini zikadizili azisathandwa kakhulu. Kodwa kunombono owandile mayelana nophethiloli we-diesel: ungcolisa ngaphezu kukaphethiloli, ngokuphambene nalokho, kancane ... U-Vrumli uchaza lezi zinkulumo!
Iqiniso noma Amanga: "Imoto enenjini kadizili ingcolisa ngaphezu kwemoto enenjini kaphethiloli"?
IQINISO, kodwa...
Udizili uqukethe izinhlobo ezahlukene zokungcola: izinhlayiya ezinhle, khona-ke i-nitrogen oxides (NOx) futhi ukukhishwa kwegesi ebamba ukushisa... Ngokuqondene nezinhlayiya ezincane, izihlungi ze-particulate (DPF) manje sezifakwa enjinini entsha kadizili. I-DPF iyadingeka, kodwa izimoto zaseFrance zindala futhi zisaqukethe izimoto eziningi zikadizili ezingenazo izihlungi.
Ngakolunye uhlangothi, injini kadizili ikhipha amagesi abamba ukushisa amancane kunemoto kaphethiloli. Injini ye-diesel ikhanya nxazonke % Kwangu-10 CO2 ngaphansi kuka kunenjini kaphethiloli! Ngakolunye uhlangothi, uphethiloli wedizili empeleni ukhipha i-NOx eningi kunemoto kaphethiloli. Ngenxa yalesi sizathu, uphethiloli we-diesel uthathwa njengongcolisa kakhulu kunophethiloli.
Eqinisweni, ukushiswa kukaphethiloli we-diesel akufani neze nophethiloli. Ngenxa yalokhu, futhi ikakhulukazi umoya oweqile okushiwo yilokhu, uphethiloli kadizili ukhiqiza ama-nitrogen oxide amaningi naphezu kwentuthuko yezobuchwepheshe eminyakeni yamuva.
Ngakho, imoto kadizili ikhipha cishe i-NOx ephindwe kabili kunemoto kaphethiloli. Kodwa-ke, ama-nitrogen oxides afaka isandla kumphumela we-greenhouse futhi cishe Ubuthi obuphindwe ka-40 kune-carbon monoxide.
E-France, izimoto zikadizili zenza u-83% wokukhishwa kwe-nitrogen oxide kanye no-99% wokukhishwa kwezinhlayiyana ezinhle kuzo zonke izimoto zabagibeli. Amashumi ezinkulungwane zokufa emhlabeni wonke unyaka ngamunye abangelwa i-NOx kanye ne-fine particulate matter, imbangela eyinhloko okuyizinjini zikadizili. Lesi yisizathu sokuthi umthetho uthuthukiswa ukuze unciphise ukungcoliswa kwalezi zimoto.
