Kugadzirisa zvinhu nenzira nhatu.
Kugadziriswa kwemagetsi nenzira nhatu kunoreva kushandurwa kwemagasi anokuvadza akadai seCO, HC uye NOx kubva muutsi hwemotokari kuita carbon dioxide, mvura nenitrogen isina njodzi kuburikidza ne oxidation nekuderedza. Chikamu chekutakura cheutsi hwenzira nhatu ichinhu chine maburi eceramic, chinoiswa mupombi yekubuda kwemhepo yakakosha. Chinonzi utsi hwemhepo nekuti hachibatanidzi mukuita kwe catalytic pachacho, asi chakafukidzwa ne coating yesimbi dzinokosha dzakadai seplatinum, rhodium, palladium uye rare earths. Ndicho chinhu chakakosha chekuchenesa kunze chakaiswa mu automobile exhaust system.
Nheyo yekushanda kwemuchina wekugadzirisa magetsi une nzira nhatu ndeyekuti: kana muchina wekuchenesa mota une nzira yepamusoro unopfuura nemuchina wekuchenesa, muchina wekuchenesa muchina wekugadzirisa magetsi une nzira nhatu unowedzera kushanda kwemagasi matatu eCO, mahydrocarbon neNOx, uye unosimudzira kuti upinde mune imwe nzira yemakemikari yekuderedza oxidation, umo CO inooxidized kuita gasi risina ruvara, risina chepfu recarbon dioxide pakupisa kwakanyanya; Mahydrocarbon anooxidized kuita mvura (H2O) uye carbon dioxide pakupisa kwakanyanya; NOx inoderedzwa kuita nitrogen neoxygen. Magasi matatu anokuvadza anova magasi asina njodzi, kuitira kuti muchina wekuchenesa upi hwemotokari ugone kucheneswa. Tichifunga kuti kuchine oxygen, chiyero chemhepo-fuel chinonzwisisika.
Nekuti mafuta acho ane sarufa, phosphorus uye mushonga wekudzivirira kugogodza MMT une manganese, zvikamu izvi zvemakemikari zvinoumba makemikari pamusoro pe sensor yeokisijeni uye mukati me three-way catalytic converter ne exhaust gas inoburitswa mushure mekupiswa. Pamusoro pezvo, nekuda kwetsika dzisina kunaka dzekutyaira dzemutyairi, kana kutyaira kwenguva refu mumigwagwa yakazara, injini inowanzova muchimiro chekupiswa kusina kukwana, izvo zvinoumba kuunganidzwa kwecarbon mu oxygen sensor uye three-way catalytic converter. Pamusoro pezvo, nzvimbo zhinji dzenyika dzinoshandisa ethanol peturu, ine simba rekuchenesa, inochenesa tsvina mukamuri yekupiswa asi haigone kuora nekutsva, saka nekubuda kwe exhaust gas, tsvina iyi ichaiswawo pamusoro pe oxygen sensor uye three-way catalytic converter. Zvinokonzerwa nezvinhu zvakawanda zvinoita kuti mushure mekunge mota yatyairwa kwenguva yakati, pamusoro pekuunganidzwa kwekabhoni muvharuvhu yekupinda nekamuri yekupisa, zvinokonzeresawo kutadza kwesensa yeokisijeni uye kutadza kwechepfu yecatalyst yenzira nhatu, kuvharika kwecatalyst yenzira nhatu uye vharuvhu yeEGR yakavharwa nesediment nezvimwe kutadza kushanda zvakanaka, zvichikonzera kushanda zvisina kunaka kweinjini, zvichikonzera kuwedzera kwekushandiswa kwemafuta, kudzikira kwesimba uye kubudiswa kwemhepo kunopfuura mwero wezvinodiwa.
Kugadziriswa kweinjini nguva dzose kunongogumira pakugadzirisa system yekuzora mafuta, system yekupinda uye system yekupa mafuta, asi hakugone kuzadzisa zvinodiwa zvekugadzirisa system yemazuva ano yekuzora mafuta, system yekupinda, system yekupa mafuta uye system yekubudisa utsi, kunyanya zvinodiwa zvekuchengetedza system yekudzora utsi. Saka, kunyangwe mota ikachengetwa zvakanaka kwenguva yakareba, zvakaoma kudzivirira matambudziko ari pamusoro apa.
Mukupindura kukundikana kwakadaro, matanho anotorwa nemakambani ekugadzirisa anowanzo kutsiva masensa eokisijeni nemasensa emagetsi matatu, asi nekuda kwedambudziko remari yekutsiva, kusawirirana pakati pemakambani ekugadzirisa nevatengi kunoramba kuripo. Kunyanya, masensa eokisijeni nemasensa emagetsi matatu asina kutsiviwa nehupenyu hwawo hwekushanda ndiwo anowanzo kukonzera kusawirirana, uye vatengi vazhinji vanototi dambudziko iri rinokonzerwa nemhando yemota.
Kuti vagadzirise dambudziko iri uye rakaoma kugadzirisa dambudziko remakambani ekugadzira mota, makambani ekugadzirisa, madhipatimendi ekugadzirisa uye madhipatimendi ekuchengetedza zvakatipoteredza, masangano akakodzera ekutsvagisa sainzi akatsvaga nekugadzira nzira itsva dzekugadzirisa injini nematekinoroji ekugadzirisa zvikanganiso zvenzira dzechinyakare dzekugadzirisa injini.
Zviri mukati meiyi tekinoroji itsva ndeizvi: pakugadzirisa nguva dzose kwevatengi, pamusoro pekutsiva oiri nekuchengetedza mafirita matatu, kuchenesa nekugadzirisa kwecatalytic converter ine nzira nhatu kunowedzerwa. Zvinhu zvayo zvehunyanzvi ndeizvi: Kusanganiswa kwe "Automobile exhaust gas control system inspection and maintenance items" uye nzira dzechinyakare dzekugadzirisa nguva dzose dzeinjini kuti dzigadzirise nzira dzechinyakare dzekugadzirisa nguva dzose dzeinjini hazvigone kusangana nezvinodiwa nezvikanganiso zvemazuva ano zvekuchengetedza injini, Mhinduro isingashande kudambudziko rekushanda zvisina kujairika kwesystem yekudzora kuburitsa emission yeinjini yekudzivirira nharaunda ichachinjwa kuita kudzivirira kushanda zvisina kujairika kwesystem yekudzora kuburitsa emission yeinjini yekudzivirira nharaunda.
1, kana paine kukuvara kwemuchina, kupisa kunopisa, makiromita anopfuura 200,000, chepfu yemutobvu, kuchenesa hakukoshi.
2, senge injini iri pakati pekuchenesa, bvisa pakarepo pombi yekubatanidza injini nemidziyo, wovhara vharuvhu yekuyerera. Tangazve injini, isina kumira zvakanaka, inogona kubatanidzwazve uye kugadziriswa.
3, tarisa kana huwandu hwemusanganiswa hwakakodzera kuona kuti mvura yacho inogona kufemerwa mugomba rinopinda.
4, kuchenesa zvikamu zvitatu kunofanira kucheneswa mushure mekubatidza throttle, nozzle yemafuta uye imba yekupisa.
5, panguva yekuchenesa, kumhanya kwekushanda hakufanirwe kunge kwakanyanya kudzivirira kupisa kwemuchina wemagetsi une nzira nhatu.
6, usadonhedze mvura yekuchenesa papendi yemotokari.
7, nzvimbo yebasa iri kure nepanobvira moto, inoita basa rakanaka rekuyeresa moto.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa zvikamu zvemota zveMG&MAUXS zvinogamuchirwa kutenga.
