Iako postoje standardi, varijacije u frakcijama nafte dovode do tolerancija prilikom proizvodnje naftnih derivata.\nPostoje zimsko i letnje gorivo koje sadr\u017ei razli\u010dite aditive prilago\u0111ene vremenskim uslovima. Ovi aditivi poma\u017eu da se gorivo ne zamrzne zimi ili da ne isparava leti, a tako\u0111e uti\u010du na performanse motora i sadr\u017eaj izduvnih gasova.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Nekada je olovo bilo prisutno u benzinu kao aditiv (olovni tetraetil), dok se danas koristi bezolovni benzin sa oktanskim brojem 95 ili 100. Aditivi se dodaju ne samo zbog otpornosti na zamrzavanje i isparavanje, ve\u0107 i da spre\u010de nekontrolisano sagorevanje pre neophodnog trenutka kada sve\u0107ica stvara varnicu kod benzinskih motora, ili kada se dostigne pritisak za samozapaljenje kod dizel motora.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Hemijska formula kerozina je uglavnom C12H26\u2212C15H32, ali mo\u017ee varirati i biti C9H20\u2212C14H30. To uti\u010de na rezultate hemijskih reakcija i koli\u010dinu vodene pare u izduvnim gasovima.
U procesu sagorevanja dolazi do slede\u0107e reakcije:
\u00bd C12H26\u2212C15H32 + 29O2 \u2192 27CO2 + 58H2O
Voda se, na temperaturama od -50 do -60 \u00b0C, momentalno kristali\u0161e i stvara beli trag.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Na kraju, ono \u0161to vas mo\u017eda najvi\u0161e zanima jeste dodavanje aluminijuma kao aditiva. On se koristi zbog osloba\u0111anja ve\u0107e koli\u010dine toplote u procesu sagorevanja i smanjenja potro\u0161nje goriva. Aluminijum se dodaje u obliku Al2O3, koji u procesu sagorevanja reaguje sa H2O, stvaraju\u0107i aluminijum okside i hidrokside, od kojih je naj\u010de\u0161\u0107i aluminijum hidroksid (AL(OH)3) u vidu belog praha koji se raspr\u0161uje s izduvnim gasovima.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
