Ko dhiziri rinoda catalytic converter?

Basa reiyo catalyst nderokudzikisa kubuda kwezvinhu zvinokuvadza zvinopisa, kusanganisira izvo zvinoburitswa neinjini yedhiziri.

Kweanopfuura makore makumi maviri, vagadziri vemota vanga vachishandisa catalytic converter mumasisitimu ekuburitsa einjini dzepeturu. Sezvo catalytic converter iri mudziyo unoshandiswa kudzikisa kubuda kwezvinhu zvinokuvadza kuita magasi emhepo, inoshandiswawo mumainjini edhiziri. Injini yedhiziri inoburitsa soot, hydrocarbons, sulfur dioxide, nitrogen oxides uye simbi: calcium, magnesium, iron uye zinc nekuda kweiyo musimboti wekushanda uye mafuta anoshandiswa. Iyo inoshandiswa zvakanyanya oxidation catalyst inopa makumi mapfumbamwe nesere kubva muzana sulfur dioxide emissions uye anopfuura 20 muzana ehydrocarbon uye kabhoni monoxide emissions. Kubva 98, kana chiyero cheEuro IV chatanga kushanda mumagetsi emagetsi einjini dzedhiziri, zvinozove zvakakodzera kuisa macatalysts uye sefa yefekitari, pamwe imwe inokonzeresa ichawedzerwa kuti isaite nitrogen oxides.
