Kodi catalytic converter ndi chiyani ndipo ndi chiyani?

Magalimoto amapangidwa ndi zigawo zambiri zovuta. Kumvetsetsa njira iliyonse m'galimoto yanu kumafuna zaka zambiri za maphunziro ndi chidziwitso. Komabe, zosinthira zida zimagwira ntchito yofunika kwambiri pakutulutsa mpweya wagalimoto yanu, kuyendetsa bwino kwamafuta, komanso thanzi lanu lonse, chifukwa chake ndikofunikira kuti mukhale ndi chidziwitso choyambira chosinthira ma catalytics. 

Aliyense wawona momwe magalimoto akuluakulu a magudumu 18 amapangira mitambo ikuluikulu ya mpweya wotulutsa mpweya, koma kodi utsi umenewu ndi wovulaza bwanji chilengedwe? Chosinthira chothandizira chimasintha zowononga zoyipa kuchokera mu injini yagalimoto yanu kukhala zotulutsa zomwe zimawononga chilengedwe. Chiyambireni kupangidwa kwa zida zosinthira mphamvu, mpweya wagalimoto wowononga ozoni watsika kwambiri. Pitilizani kuwerenga kuti mudziwe zambiri za ma converter othandizira komanso momwe mungasungire galimoto yanu kuyenda zaka zikubwerazi. 

Mbiri ya catalytic converters 

Sikuti nthawi zonse magalimoto ankatsatira malamulo oteteza chilengedwe. Mu 1963, dziko la United States linapereka lamulo la Clean Air Act kuti lichepetse kuchuluka kwa zowononga zowononga zomwe zimatulutsidwa kuchokera kumagwero osasunthika komanso mafoni. Makampani opanga magalimoto ku United States adakula kwambiri mu 1963 ndi magalimoto opitilira 1965 miliyoni, zomwe zidadzutsa nkhawa za mpweya woipa. Mu 1965, boma la feduro linasintha lamulo la Clean Air Act kuti liphatikizepo miyezo yoyamba yotulutsa magalimoto mu National Emission Standards Act. Magalimoto onse opangidwa ku US pambuyo pa XNUMX amayenera kukwaniritsa miyezo yoperekedwa ndi boma la feduro. 

Katswiri wamakina waku France, Eugène Houdry, adapanga chosinthira chothandizira muzaka za m'ma 1950s kuti achepetse kuchuluka kwa zoipitsa zowononga zomwe zimatulutsidwa kuchokera ku matumba a utsi wamagalimoto ndi injini zamafuta. Dziko la US lidayamba kupanga masinthidwe opangira anthu ambiri muzaka za m'ma 1970 kuti akwaniritse miyezo yotulutsa mpweya yokhazikitsidwa ndi boma la feduro. Kuyambira nthawi imeneyo, galimoto iliyonse yopangidwa ku US yakhala ndi zida zosinthira.

Kodi catalytic converter ndi chiyani? 

Ma Catalytic converters amamangiriridwa pansi pagalimoto yanu pamakina otulutsa mpweya pakati pa muffler ndi tailpipe. Chosinthira chothandizira chimakhala ndi thupi lalikulu lachitsulo, mizere iwiri ndi chothandizira chopangidwa kuchokera kuzitsulo zamtengo wapatali monga platinamu, rhodium ndi palladium. Utoto wa galimoto yanu umadutsa mupaipi kupita ku chothandizira zisa, pomwe mamolekyu owopsa amasinthidwa kukhala zinthu zowononga chilengedwe. 

Mwachitsanzo, popanda chosinthira chothandizira, mamolekyu owopsa opangidwa ndi galimoto yanu, monga nitric oxide ndi carbon monoxide, amatha kulowa mumlengalenga momasuka. Zitsulo zamtengo wapatali mu otembenuza catalytic amasintha mapangidwe a nitrogen oxide ndi carbon monoxide kukhala mamolekyu ogwirizana ndi chilengedwe a carbon dioxide ndi nitrogen. Mitundu iwiri ikuluikulu ya zothandizira zomwe zimagwiritsidwa ntchito pamagalimoto ndi: 

Recovery Catalysts 

Chothandizira kuchira chimalekanitsa zinthu zovulaza za nitric oxide kukhala ma molekyulu a nayitrogeni ndi okosijeni - platinamu ndi rhodium zimamangiriza ku mamolekyu okosijeni, zomwe zimapangitsa kuti mamolekyu osavulaza a nayitrogeni adutse mutoliro. Mamolekyu otsala a okosijeni amathandizira kuchepetsa mpweya woipa kudzera mu okosijeni. 

Zothandizira oxidation 

Zothandizira okosijeni zimawotcha ma hydrocarbon owopsa ndi carbon monoxide kupanga mamolekyu a okosijeni. Platinamu ndi palladium zimagwiritsa ntchito mpweya womasulidwa kuchokera kuzinthu zochepetsera kuti zimange mamolekyu owonjezera a okosijeni ku carbon monoxide ndi ma hydrocarbons, kupanga mpweya woipa ndi madzi. 

Chosinthira chothandizira ndi chida chofunikira chowongolera utsi m'magalimoto. Popanda otembenuza othandizira, ma hydrocarbon owopsa ndi mamolekyu a nitrogen oxide amawononga ozoni wapadziko lapansi ndikuwonjezera kutulutsa mpweya woipa mumlengalenga. 

Momwe mungadziwire ngati chosinthira chanu cha catalytic chikugwira ntchito 

Ma Catalytic converter amachepetsa kutulutsa kwamagalimoto ndikuwongolera kuchuluka kwamafuta komanso moyo wamagalimoto. ECU, gawo loyang'anira galimoto yanu, limasonkhanitsa nthawi zonse deta kuchokera ku makina osinthira kuti atsimikizire kuti injiniyo imalandira mpweya wokwanira kuti imalize kutembenuza kochititsa chidwi ndikuwotcha mafuta bwino. 

Magetsi ochenjeza a injini amatha kuwonetsa kuyaka kosakwanira kwamafuta chifukwa cha zowonongeka zosinthira zida. Nthawi zonse fufuzani ntchito zosinthira akatswiri ngati galimoto yanu ikuchedwa, ikuvuta kuthamanga, kapena imatulutsa fungo la dzira lowola la sulfure. Kusintha chosinthira chothandizira kumawononga madola masauzande ambiri, choncho nthawi zonse tengerani galimoto yanu kwa makaniko apafupi kuti mukagwire ntchito pachaka. 

Chifukwa cha zitsulo zamtengo wapatali zomwe zili m'matembenuzidwe othandizira, magalimoto amatha kubedwa. Kuti galimoto yanu ikhale yotetezeka, lingalirani kuwotcherera chosinthira chothandizira pansi pagalimoto yanu kapena kukhazikitsa khola lachitsulo kuti mbava zisamalowe. Zosintha za Catalytic ndizofunikira pagalimoto yanu, chifukwa chake zisungeni zotetezeka nthawi zonse!
