Ndi Converter othandizira Kodi

Zonse mwamakono machitidwe galimoto utsi monga Converter othandizira. chipangizo lakonzedwa kuchepetsa mpweya zinthu zoipa kuchokera ku mipweya utsi mkhalidwe. The Converter othandizira ntchito ngati mayunitsi mphamvu dizilo, komanso petulo. Kukhazikitsa wake kapena yomweyo kumbuyo utsi zobwezedwa, kapena mwachindunji muffler lapansi. The neutralizer mpweya utsi zikuphatikizapo chonyamulira wagawo, ndi kutchinjiriza matenthedwe nyumba ya.

chipangizo

The mbali yaikulu imatengedwa kuti asalalikire chonyamulira. Iwo amapangidwa ceramic refractory. Kamangidwe ka ngati chipika ndi zizindikiro kuchuluka kwa maselo kotenga, zayamba kukula dera kukhudzana ndi mpweya utsi. pamwamba TACHIMATA ndi zinthu zapadera, catalysts (palladium, pulatinamu ndi rhodium). Ndi zinthu izi, pali mathamangitsidwe mosiyanasiyana mankhwala.

Palladium ndi pulatinamu ndi makutidwe ndi okosijeni chothandizira. Iwo amapereka makutidwe ndi okosijeni wa chimasanduka ndi moyenera, kulimbikitsa kutembenuka kwa mpweya monoxide, mpweya woipa ndi nthunzi. A chothandizira kuchepetsa ndi rhodium. Izo ntchito kuchepetsa oxides asafe mu asafe zabwinobwino. Iwo likukhalira kuti mitundu itatu catalysts mu mpweya wa utsi yafupika zili zinthu zitatu zosiyana zoipa. Choncho, chipangizo oterowo amatchedwa atatu njira othandizira Converter.

Block chonyamulira ili mu nyumba zitsulo. Pakati pa iwo ndi kutentha chimateteza wosanjikiza. The chothandizira thupi ndi kachipangizo oxygen.

Imayenera ntchito chipangizo mu funso kukufika pa kutentha ³⁰⁰ ° C, kenako 90 peresenti anachedwa zinthu zoipa (kwa Converter izi othandizira waikidwa yomweyo kumbuyo utsi zobwezedwa).

Features

The catalysts zimathandiza kwambiri kuchepetsa utsi mpweya kawopsedwe ndipo n'chifukwa pafupifupi ziribe mphamvu pa injini mphamvu ndi mafuta mowa. Ndi chipangizo uyu kumbuyo kuthamanga ukuwonjezeka pang'ono chifukwa cha zomwe galimoto mphamvu wagawo wotaya malita 2-3. a. Theoretically utsi chothandizira ukhoza kukhala mpaka kalekale, chifukwa zitsulo wapamtima pa zochita mankhwala simudzathedwa. Komabe, ikusonyeza kumapeto, moyo mwa zipangizozi ndi malire ake.

Mwachitsanzo, imodzi mwa ntchito zomwe akuthamanga kulephera kwa converters - ndi osalimba ceramic maselo, amene kugwedezeka lakuthwa (ngati galimoto pa tokhala liwiro, itagwa Nakonso kapena ngakhale chirknet thupi kanthu chothandizira) kungawonongedwe, imbaenda kulephera kwa anati chipangizo. Tsopano ife anayamba kuoneka converters, amene m'malo ceramic - zitsulo monolith. Komanso kugonjetsedwa ndi kuwonongeka. Chifukwa china kulephera kwa Converter othandizira - ndi mafuta. Leaded mafuta wolemera tetraethyl kutsogolera kuti "nkhaka" pamwamba maselo. Motero, zochita zonse zidzatha. Mdani chotsatira ndi chothandizira zikuchokera mafuta cholakwika. Choncho, osakaniza munali kochulukira kuchuluka kwa chimasanduka, kuwononga chipangizo, ndipo amachititsa lakuthwa kutenthedwa osauka kwambiri, tingayambe chiwonongeko cha monolith lapansi. Osati zochepa zoopsa ndi lakuthwa kutentha kusintha, monga pamene galimoto amalowa chithaphwi chija. Komanso ingawononge ceramic.

Nthawi zambiri, Converter othandizira, komanso njira ina bwanji zinthu ntchito.
