Nzira nhatu-catalysis.
Three-way catalysis inoreva kushandurwa kwemagasi anokuvadza akadai seCO, HC uye NOx kubva mumotokari inopopotera kuita isingakuvadzi kabhoni dhayokisaidhi, mvura uye nitrogen kuburikidza neoxidation uye kuderedza. Iyo inotakura chikamu chetatu-nzira inokonzeresa chidimbu che porous ceramic zvinhu, iyo inoiswa mune yakakosha pombi yekupedza. Inonzi mutakuri nekuti haitore chikamu mune inokonzeresa maitiro pachayo, asi yakafukidzwa neyakavharidzirwa yesimbi dzakakosha senge platinamu, rhodium, palladium uye isingawanzo pasi. Ndiyo inonyanya kukosha yekuchenesa yekunze mudziyo wakaiswa mumotokari exhaust system.
Musimboti wekushanda wetatu-nzira inoshandura inoshandura ndeye: kana yakakwira-tembiricha yemotokari ichipfuura nepamudziyo wekuchenesa, iyo inonatsa mune matatu-nzira inoshandura inoshandura inosimudzira basa remagasi matatu CO, hydrocarbons uye NOx, uye kusimudzira. kuti iite imwe oxidation-reduction chemical reaction, umo CO oxidized kuita isina ruvara, isiri-chepfu kabhoni dioxide gasi pakupisa kukuru; MaHydrocarbons anoiswa oxidized kumvura (H2O) uye kabhoni dhaikisaidhi pakudziya kwakanyanya; NOx inoderedzwa kuita nitrogen uye oksijeni. Matatu anokuvadza magasi anova magasi asingakuvadzi, kuitira kuti utsi hwemotokari hucheneswe. Tichifunga kuti kuchine okisijeni iripo, mwero wemafuta emhepo unonzwisisika.
Nekuti mafuta ane sarufa, phosphorous uye antiknock agent MMT ine manganese, izvi zvinoumba makemikari zvinoumba makemikari macomplexes pamusoro peiyo okisijeni sensor uye mukati metatu-nzira inoshandura inoshandura ine exhaust gasi inoburitswa mushure mekutsva. Uye zvakare, nekuda kwemaitiro ekutyaira akashata emutyairi, kana kutyaira kwenguva refu mumigwagwa yakatsvikinyidzana, injini kazhinji iri munzvimbo isina kukwana yekupisa, iyo inoumba kabhoni kuunganidza muokisijeni sensor uye matatu-nzira catalytic converter. Mukuwedzera, nzvimbo dzakawanda dzenyika dzinoshandisa ethanol peturu, iyo ine simba rekuchenesa simba, ichachenesa tsvina muimba yekupisa asi haigoni kuora uye kupisa, saka nekubuda kwegesi inopera, tsvina iyi ichaiswawo pamoto. pamusoro peiyo okisijeni sensor uye matatu-nzira inoshandura inoshandura. Imhaka yezvikonzero zvakawanda zvekuti mushure mekunge mota yafambiswa kwenguva yakati rebei, mukuwedzera kune kabhoni kuunganidzwa muvharuvhu yekudya uye mukamuri yekupisa, zvinokonzeresa iyo okisijeni sensor uye nzira nhatu dzinokonzeresa chepfu kukundikana, iyo mitatu. -nzira inodzivirira kuvhara uye EGR valve yakavharwa ne sediment uye kumwe kukundikana, zvichiita kuti injini ishande isina kujairika, zvichiita kuti mafuta awedzere kushandiswa, kuderera kwesimba uye kupera kunopfuura kudarika.
Chinyakare gadziriso yeinjini inogumira pakugadziriswa kweiyo lubrication system, yekudyara sisitimu uye mafuta ekupa system, asi haigone kuzadzisa zvizere zvekugadzirisa zvinodiwa zvechizvino injini lubrication system, intake system, mafuta ekupa system uye exhaust system, kunyanya zvinodiwa zvekuchengetedza. ye emission control system. Nokudaro, kunyange kana motokari ichichengetwa kazhinji kwenguva yakareba, zvakaoma kudzivisa matambudziko ari pamusoro apa.
Mukupindura kukundikana kwakadaro, matanho anotorwa nemabhizinesi ekugadzirisa anowanzo kutsiva maokisijeni sensors uye matatu-nzira catalytic converters, asi nekuda kwedambudziko rekutsiva mutengo, kukakavara pakati pemabhizinesi ekugadzirisa uye vatengi kunoenderera. Kunyanya, iwo maokisijeni sensors uye matatu-nzira catalysts asina kutsiviwa nehupenyu hwavo hunobatsira anowanzo tarisisa yekukakavadzana, uye vatengi vazhinji vanototi dambudziko iri kumhando yemotokari.
Kuti ugadzirise musoro uyu uye wakaoma kugadzirisa dambudziko remabhizinesi ekugadzira mota, mabhizinesi ekuchengetedza, madhipatimendi ekuchengetedza ekuchengetedza uye madhipatimendi ekuchengetedza kwezvakatipoteredza, akakodzera sainzi masangano ekutsvagisa akatsvaga uye akagadzira seti nyowani yemaitiro ekugadzirisa injini uye matekinoroji ehurema. zvechinyakare injini routine kugadzirisa nzira.
Zviri mukati meiyi tekinoroji nyowani ndeiyi: kana uchiita gadziriso yenguva dzose kune vatengi, kunze kwekutsiva oiri uye kuchengetedzwa kwemafirita matatu, kucheneswa nekugadzirisa kwetatu-nzira catalytic converter inowedzerwa. Yayo tekinoroji maficha ndeaya: Organic musanganiswa we "Motokari inopedza gasi yekudzora gasi system yekuongorora uye kugadzirisa zvinhu" uye yechinyakare injini yekugadzirisa nzira dzekugadzira iyo yechinyakare injini yekugadzirisa nzira haigone kusangana nezvinodiwa zvemazuva ano ejini kugadzirisa kukanganisa, Iyo passive mhinduro dambudziko rekushanda zvisina kujairika kweiyo emission control system yeinjini yekudzivirira kwezvakatipoteredza ichachinjirwa kune inoshanda kudzivirira kweabnormal mashandiro eemission control system yeinjini yekudzivirira kwezvakatipoteredza.

2, senge injini iri pakati pekucheneswa, pakarepo bvisa injini uye midziyo yekubatanidza hose, uye vhara kuyerera kwevhavha. Tangazve injini, isingaite yakatsiga, inogona kubatanidzwazve uye kugadziridzwa.
3, tarisa kana musanganiswa wemusanganiswa wakakodzera kuti uve nechokwadi chekuti mvura inogona kufemerwa mumhute inlet.
4, kuchenesa zvikamu zvitatu kunofanirwa kucheneswa mushure meiyo throttle, furo nozzle uye kamuri yekupisa.
5, panguva yekuchenesa, iyo isingaite yekumhanya haifanirwe kunge yakakwira zvakanyanya kudzivirira kupisa kweiyo nzira nhatu inoshandura inoshandura.
6, usadonhedze mvura yekuchenesa papende yemotokari.
7, nzvimbo yebasa iri kure nechitubu chemoto, ita basa rakanaka rezviyero zvemoto.
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa MG&MAUXS zvikamu zvemotokari zvinogamuchirwa kutenga.
