Catalyst - dhizaini uye kushanda. Chii chinonzi catalytic device inoshandiswa?
Zviri mukati
Chii chinonzi catalyst uye nei ichidikanwa?
Ichi chinhu chinoshandiswa sechikamu cheiyo exhaust system iri mupombi yekuburitsa. Iyo catalytic converter yemotokari yakafanana nepombi yedhayamita yakakura kupfuura chikamu chekuburitsa, icho chinosanganiswa nekuiswa kwezvinhu zvinokonzeresa mairi. Unogona kuzviziva zviri nyore mumotokari dzechizvarwa chekare, peturu nedhiziri.
Mune mamodheru akagadzirwa iye zvino, nhamba yevashanduri vecatalytic vanoiswa mumotokari imwe yakawedzera. Izvi zvinokonzerwa nekuwedzera kunoramba kuchikwira kwemaitiro ekuburitsa uye kukanganisa hunhu hwezvinhu zvinokuvadza zvinobuda mupombi. Kuvandudzwa kwetekinoroji kwakakonzerawo kugadzirwa kweakakosha mafirita emota dzedhiziri, ayo anonzi DPF. Parizvino, dzinenge mota dzese dzedhiziri pamusika dzine sefa yakadaro.
Chimiro che catalyst uye chiito chayo
Kunze, iyo catalytic inoshandura inofanana neye exhaust silencer uye, zvichienderana nemotokari, inogona kunge ine flatter kana cylindrical chimiro. Mumotokari dzemazuva ano, inoshandiswa senge yekupedza manifold insert. Kubatsira kwemhinduro iyi inokurumidza kupisa uye kushanda kwakanyatsoshanda. Mukati meiyo catalytic mudziyo mune zvinotevera zvikamu:
- heat shield;
- ceramic kana simbi musimboti;
- kuisa muzinga.
Chinoshanda chinoshanda sei?
Unoda kuziva kuti catalyst inoshanda sei? Iyo yose nzira inotanga apo zvinokuvadza zvinopisa zvigadzirwa zvemusanganiswa zvinopinda mukati maro. Aya ndiwo mahydrocarbon, carbon monoxide uye nitrogen oxides. Nekuda kwechimiro uye kuvapo kweplatinamu, zvimwe zvinhu uye oxides yealumina uye cerium oxide, NOX inobviswa uye, semhedzisiro, nitrogen N inoburitswa mumhepo.2. Mune chimwe chikamu che catalyst, CO yakasvibiswa uye CO inoumbwa.2 ini h2O.
Catalyst mumotokari - kusimba
Iyo catalytic inoshandura, kunyangwe ichienderera mberi nekushanda uye kuratidzwa nekuchinja kwemamiriro ekunze, chinhu chinodzivirira kukuvara uye chinogara chakasimba exhaust system chikamu. Mumamiriro ezvinhu akanaka, inogona kushanda zvisina mhosva kweanopfuura makiromita 200. Zvisinei, nekushanda kwemotokari, kushanda kwayo kunoderera, uye inogona kuwanzwa nekushaya injini.
Mota catalytic converter - malfunctions
Kutadza kweCatalyst kunogona kuwanzo kuve kwemakanika uye kunosanganisira kukuvadzwa kune zvinobatanidza kana casing. Somugumisiro wekurova chipingamupinyi kana pasi pesimba rekuonekwa kamwe kamwe kwemvura kubva mugomba, catalytic converter mumotokari inogona kukundikana. Pamusoro pezvo, chikanganiso chekubatidza system chinogona kukonzera kuti mafirita emukati atadze. Chikonzero chavo chinowanzova parutivi rwechikanganiso chekupisa.
Kana iyo mafuta isingapisi muhumburumbira, inopinda mukati meiyo exhaust system uye inobatidza mu catalytic converter. Ichi chiitiko chinosimudza tembiricha mukati memudziyo uye chinoparadza katuriji, kukanganisa kunaka kwekubuda kwegasi kucheneswa. Kuedza kutanga motokari mutow kana "jolts" kunopa zvakafanana. Nekuda kweizvozvo, iyo isina kupiswa dhizaini yemafuta inopindawo mune exhaust system uye mhedzisiro yekupedzisira yakafanana neyakapfuura.
Zviratidzo zvekukuvara kwemota catalyst
Mumotokari dzemazuva ano, yakaputsika catalytic converter inoratidzwa nekuderera kwesimba. Sei? Izvi zvinokonzerwa nekuti iyo sensor yakavakirwa mukati meiyo catalytic inoshandura inogamuchira hunhu hwakasiyana neiyo fekitori. Idzi ruzivo runoshandiswa nemutongi kuti agadzirire kuumbwa kwemafuta-mhepo musanganiswa, saka chero kukanganisa kunotungamirira kukuchinja kwayo uye, sechikonzero, kuparara kwekushanda kwemotokari.
Iwe unogona kuona yakakuvadzwa catalytic inoshandura mumotokari nekumaka pane dashboard. Kazhinji ipapo chiedza cheorenji chinouya cheki injini. Ehe, haisi iyo chete inokonzera iyo catalytic mudziyo, saka kutaridzika kwayo pachiratidziro hazvireve kuti chinhu chakatsanangurwa chakakuvadzwa. Imwe nzira ndeye organoleptic yekudzidza mamiriro eiyo catalyst. Chinhu chakakanganisika chinoita kuti chinzwe nekugogodzwa kwesimbi uye kurira.
Nzira yekugadzirisa sei catalytic converter mumotokari?
Imwe yenzira huru ndeye catalyst regeneration. Zvichienderana neshanduro, izvi zvinogona kukubhadhara iwe kupfuura chiuru chezlotys. Nekudaro, ichiri yakachipa zvakanyanya pane kutenga chigadzirwa chitsva. Mune zvimwe zviitiko, inoshandura inoshandura haigone kugadziriswa uye iwe unofanirwa kusarudza chigadzirwa chitsva. Sezvineiwo, pane zvakawanda zvinotsiva pamusika izvo zvakachipa zvakanyanya kupfuura zvikamu zvekutanga. Izvo zvinowanikwawo sezvikamu zvepasi rose zvakafananidzwa maererano neyuniti simba.
Mamiriro acho anowedzera kuoma kana mota yakashongedzerwa akati wandei anoshandura anoshandura, kusanganisira imwe iri mune exhaust manifold. Mutengo wayo unogona kudarika zviuru zvinoverengeka zvezlotys, izvo zvinogona kubvisa chikwama chako. Izvo zvakakosha kuti mushure mekuparara, iyo mota catalytic converter inofanirwa kuraswa. Naizvozvo, kuisa mudziyo wakashandiswa kunopesana nemutemo. Mukuwedzera, kushanda kwayo kunowanzova kukuru uye kusingazivikanwi.
Kana kuti zvimwe cheka...
Sekutaura kunoita maamateur tuners, "dzima iyo catalyst, kuchave nemabhiza mazhinji." Kune rimwe divi, ichi ichokwadi, nekuti chinhu ichi chinodzikamisa kuyerera kwemahara kwemagasi. Kubviswa kwayo kune imwe nzvimbo kunowedzera kushanda kwemotokari. Nekudaro, ziva kuti mota isina catalytic converter haienderane nehomogation yemugadziri. Nekuda kweizvozvo, iyo diagnostician haizokwanisi kusarudza pamhedzisiro yakanaka panguva yekuedzwa. Mukuwedzera, kubvisa motokari ye catalyst kunobatanidza nekuchinja kwekuverenga mujini injini. Sezvauri kuona, iyo catalytic inoshandura inoita basa rakakosha mumotokari, uye isu tinogona kutarisira kushanduka kwayo mumakore anotevera. Ecology inomanikidza kushandiswa kwedzimwe nzira dzemberi dzekupedza gasi kuchenesa. Paunenge uchitenga motokari yakashandiswa, unofanira kutarisa mamiriro emotokari inoshandura inoshandura kudzivirira kugadzirisa kunodhura kana kutsiva.
