Chii chinoita catalytic converter?
Zviri mukati
Iyo yemazuva ano exhaust system yakanyanya kufambira mberi kupfuura yaivepo kunyange makumi mashoma emakore apfuura. Ichiziva kuti mota yepakati ndiyo inokonzeresa kusvibiswa kwenyika, hurumende yeUS yakapasisa Mutemo Wakachena Wemhepo unoda kuti mota dzese dzakagadzirwa mushure mezuva iroro dzive neshanduko inoshanda inoshandura, pakati pezvimwe zvinhu zvakakosha. Yako "katsi" inogara mumotokari yako epoust system, ichimhanya chinyararire uye kuderedza zvinokuvadza zvinobuda.
Chii chekuita?
A catalytic converter ine basa rimwe chete: kudzikisa zvinokuvadza zvinobuda mumotikari yemota yako kuderedza kusvibiswa. Inoshandisa catalyst (chaizvoizvo inodarika imwe) kushandura makemikari anokuvadza akadai secarbon monoxide, mahydrocarbon, uye maokisijeni enitrogen kuita zvinhu zvisingakuvadzi. Iyo catalyst inogona kuva imwe yemasimbi matatu kana musanganiswa wavo:
- Platinum
- Palladium
- Rhodium
Vamwe vagadziri vanoshandura vanogadzira vava kuwedzera goridhe kumusanganiswa nekuti yakachipa kupfuura mamwe masimbi matatu uye inogona kupa oxidation iri nani kune mamwe makemikari.
Chii chinonzi oxidation?
Oxidation inoshandiswa mupfungwa iyi kureva "kupisa". Chaizvoizvo, iyo catalyst inopisa kune yakanyanya kupisa tembiricha. Matembiricha aya, akasanganiswa neakasarudzika masimbi anoshandiswa seanokonzeresa, anogadzira shanduko yemakemikari muzvinhu zvisingadiwe. Nekushandura makemikari anoumbwa, anova asina ngozi.
Carbon monoxide (chepfu) inoshanduka kuita carbon dioxide. Nitrogen oxides yakaputsika kuita nitrogen uye okisijeni, zvinhu zviviri zvinowanzoitika mumhepo zvakadaro. Mahydrocarbon anosara pamafuta asina kupiswa anoshandurwa kuita mvura uye carbon dioxide.
