Mfundo Yogwira Ntchito Ya Exhaust Catalytic Converter
Mfundo yogwiritsiridwa ntchito ya exhaust catalytic converter ndi motere: Pamene mpweya wotentha kwambiri-udutsa pachipangizo choyeretsera, choyeretsa mu chosinthira chothandizira chimawonjezera ntchito ya CO, HC, ndi mpweya wa NOx, kupititsa patsogolo kutulutsa kwa okosijeni{1}kuchepetsa kukhudzidwa kwa makemikolo. Mwachindunji, CO imapangidwa ndi okosijeni pakatentha kwambiri kukhala yopanda mtundu, -yopanda mpweya woipa; HC mankhwala ndi oxidized pa kutentha kwambiri mu madzi (H2O) ndi mpweya woipa; ndipo NOx imachepetsedwa kukhala nayitrogeni ndi mpweya. Mipweya itatu yoopsayi imasinthidwa kukhala mpweya wopanda vuto, motero amayeretsa utsi wagalimoto.
Chosinthira chotulutsa mpweya chimakhala chofanana ndi muffler. Kunja kwake kumapangidwa ndi cylindrical pogwiritsira ntchito ma sheet -awiri osanjikiza osapanga dzimbiri. Insulation material-asbestos fiber feel-imayikidwa pakati-pawiri mapepala osanjikiza. Choyeretsacho chimayikidwa mkati, chokhazikika pakati pa ma mesh partitions. Choyeretsacho chimakhala ndi chonyamulira komanso chothandizira. Chonyamuliracho nthawi zambiri chimapangidwa ndi aluminium oxide, ndipo mawonekedwe ake amatha kukhala ozungulira, polygonal, kapena ma mesh partition. Choyeretsa, chomwe chimadziwikanso kuti chothandizira, ndicho chomwe chimagwira ntchito ngati chothandizira. Zothandizira nthawi zambiri zimapangidwa ndi platinamu, rhodium, kapena palladium. Kupopera imodzi mwa izi pa chonyamulira kumapanga woyeretsa.
