Kushanda Nheyo yeExhaust Catalytic Converter

Maitiro ekushanda eexhaust catalytic converter ndeaya anotevera: Kana moto-unopisa wetembiricha wakakwirira ukapfuura nemumudziyo wekuchenesa, chinochenesa chiri mucatalytic converter inovandudza kushanda kweCO, HC, uye NOx magasi, kukurudzira kumwe kuokisisa{1}kuderedza kuita kwemakemikari. Kunyanya, CO inoiswa oxidized patembiricha yepamusoro kuita isina ruvara, isina-chepfu carbon dioxide; Mishonga yeHC inoiswa oxidized pakupisa kwakanyanya mumvura (H2O) uye carbon dioxide; uye NOx inoderedzwa kuita nitrogen uye oksijeni. Aya magasi matatu anokuvadza anoshandurwa kuita magasi asingakuvadzi, nekudaro achichenesa mhepo yemotokari.

Iyo exhaust catalytic converter yakafanana neye muffler. Kunze kwayo kwakagadzirwa necylindrical structure pachishandiswa maviri-layered Stainless steel sheets. Insulation material-asbestos fiber yakanzwa-inoiswa pakati pe-layered sheets. Mumiririri wekuchenesa anoiswa mukati, akaiswa pakati pemesh partitions. Mushandi wekuchenesa anosanganisira mutakuri uye catalyst. Iyo inotakura inowanzo gadzirwa nealuminium oxide, uye chimiro chayo chinogona kuve chakatenderera, polygonal, kana mesh partition. Iyo yekuchenesa mumiriri, inozivikanwawo secatalyst, ndiyo inotoita sechinhu chinokonzeresa. Catalysts anowanzo kugadzirwa neplatinamu, rhodium, kana palladium. Kupfapfaidza imwe yeiyi pane inotakura inoumba mumiriri wekuchenesa.
