Kodi dizilo ikufunika chosinthira chothandizira?

Ntchito ya chothandizira ndi kuchepetsa utsi wa zinthu zowononga utsi, kuphatikizapo zomwe zimatulutsidwa ndi injini ya dizilo.

Kwa zaka zoposa 20, opanga magalimoto akhala akugwiritsa ntchito makina osinthira magetsi pamakina otulutsa mafuta amafuta. Popeza chosinthira chothandizira ndi chipangizo chomwe chimagwiritsidwa ntchito kuchepetsa kutulutsa kwa zinthu zovulaza kukhala mpweya wotulutsa mpweya, chimagwiritsidwanso ntchito mu injini za dizilo. Injini ya dizilo imatulutsa mwaye, ma hydrocarbon, sulfure dioxide, nitrogen oxides ndi zitsulo: calcium, magnesium, iron ndi zinc chifukwa cha mfundo yogwira ntchito ndi mafuta omwe amagwiritsidwa ntchito. Chothandizira chogwiritsidwa ntchito kwambiri cha okosijeni chimapereka 98 peresenti yotulutsa mpweya wa sulfure dioxide ndi zoposa 80 peresenti ya hydrocarbon ndi mpweya wa carbon monoxide. Kuyambira 2005, mulingo wa Euro IV ukayamba kugwira ntchito pamakina otulutsa ma injini a dizilo, padzakhala kofunikira kukhazikitsa zopangira ndi fyuluta ya tinthu tating'onoting'ono, mwina chothandizira chowonjezera chidzawonjezedwa kuti muchepetse nitrogen oxide.
