fa'atosina tiso

O le catalytic converter o se masini e faʻaaogaina e faʻaitiitia ai le tuʻuina atu o vaega leaga i kasa faʻamalo ma faʻaaogaina foi i afi afi.

Mo le sili atu i le 20 tausaga, o loʻo faʻaaogaina e le au gaosi taʻavale le faʻaliliuina o le catalytic i le faʻaogaina o masini afi. Talu ai o le catalytic converter o se masini e faʻaaogaina e faʻaitiitia ai le tuʻuina atu o vaega leaga i kesi gase, e faʻaaogaina foi i afi afi.

O le afi tiso emits soot, hydrocarbons, sulfur dioxide, nitrogen oxides ma metals: calcium, magnesium, iron ma zinc ona o le mataupu faavae o le gaioiga ma le suauu faʻaaogaina. E mafai ona fa'aitiitia le sulfur dioxide e le 98 pasene le fa'aogaina lautele ole fa'ama'i fa'ama'i, fa'amalulu ma le carbon monoxide e sili atu ile 80 pasene.

O le Euro IV standard ua faʻamalosia talu mai le 2005. I le fa'aogaina o masini tiso, o le fa'apipi'iina o fa'ato'aga ma se fa'amama fa'ama'i o le a mana'omia, masalo o le a fa'aopoopoina se fa'aopoopoga fa'aopoopo e fa'afitia ai le nitrogen oxides.
