Kodi catalytic converter imachita chiyani?
Makina amakono otulutsa magalimoto ndi apamwamba kwambiri kuposa omwe analipo ngakhale zaka makumi angapo zapitazo. Pozindikira kuti galimoto wamba ndiye gwero lalikulu la kuipitsa padziko lonse lapansi, boma la US lidapereka lamulo loti magalimoto onse opangidwa pambuyo pa tsikulo akhale ndi chosinthira chothandizira, pakati pa zinthu zina zofunika kwambiri. "mphaka" wanu amakhala mu utsi wa galimoto yanu, kuthamanga mwakachetechete ndi kuchepetsa mpweya woipa.
Ndi kuchita chiyani?
Chosinthira chothandizira chili ndi ntchito imodzi: kuchepetsa utsi woyipa wagalimoto yanu kuti muchepetse kuipitsidwa. Amagwiritsa ntchito chothandizira (kwenikweni choposa chimodzi) kutembenuza mankhwala owopsa monga carbon monoxide, ma hydrocarbon, ndi ma oxide a nayitrogeni kukhala zinthu zopanda vuto. Chothandizira chikhoza kukhala chimodzi mwazitsulo zitatu, kapena kuphatikiza:
- Platinum
- Palladium
- Rhodium
Ena opanga ma converter othandizira tsopano akuwonjezera golide pakusakaniza chifukwa ndi wotsika mtengo kuposa zitsulo zina zitatuzo ndipo atha kupereka okosijeni kwamankhwala ena.
Kodi okosijeni ndi chiyani?
Oxidation imagwiritsidwa ntchito mwanjira iyi kutanthauza "kuwotcha". Kwenikweni, chothandizira chimatenthedwa ndi kutentha kwambiri. Kutentha kumeneku, pamodzi ndi zinthu zapadera za zitsulo zomwe zimagwiritsidwa ntchito monga chothandizira, zimapanga kusintha kwa mankhwala m'zinthu zosafunikira. Mwa kusintha kapangidwe ka mankhwala, amakhala opanda vuto.
Mpweya wa carbon monoxide (poizoni) umasanduka mpweya woipa. Ma nitrogen oxides amaphwanyidwa kukhala nayitrogeni ndi mpweya, zinthu ziwiri zomwe zimachitika mwachilengedwe mumlengalenga. Ma hydrocarbon otsala pamafuta osapsa amasinthidwa kukhala madzi ndi mpweya woipa.
