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 weiyo nzira nhatu inoshandura inoshandura ndeye: kana iyo yakanyanya-tembiricha yekupopota ichipfuura nemuchina wekunatsa, iyo inochenesa munzira nhatu-inoshandura inoshandura inosimudzira kushanda kwemagasi matatu CO, hydrocarbons uye NOx, uye nekuisimudzira kuti ipinde mune imwe oxidation-yekudzikisa kemikari reaction, umo CO isina oxidized mumhepo ine chepfu; 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 kwegasi rinopera, tsvina iyi ichaiswawo pamusoro peiyo okisijeni sensor uye nzira nhatu-catalytic converter. Imhaka yezvikonzero zvakawanda zvekuti mushure mekunge mota yatyairwa kwenguva yakati rebei, mukuwedzera kune kabhoni kuunganidzwa muvharuvhu yekudya uye mukamuri yekupisa, zvinokonzeresa iyo okisijeni sensor uye nzira nhatu dzinokonzeresa chepfu kutadza, nzira nhatu dzinokonzeresa kuvharika uye EGR vharafu yakavharwa ne sediment uye kumwe kutadza, zvichikonzera kushandiswa kwemafuta, kuderera uye kupera simba kweinjini. standard.
Chinyakare gadziriso yeinjini inogumira pakugadziriswa kweiyo lubrication system, yekudyara system uye mafuta ekupa system, asi haigone kuzadzisa zvizere zvekugadzirisa zvinodiwa zvechizvino injini lubrication system, system yekudya, system yekugovera mafuta uye exhaust system, kunyanya zvinodiwa zvekuchengetedza 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 zvakaoma kugadzirisa dambudziko remabhizinesi ekugadzira mota, mabhizinesi ekugadzirisa, madhipatimendi ekuchengetedza ekuchengetedza uye madhipatimendi ekuchengetedza kwezvakatipoteredza, akakodzera sainzi masangano ekutsvagisa akatsvaga uye akagadzira seti nyowani yemaitiro ekugadzirisa injini nzira uye matekinoroji ekukanganisa kwechinyakare injini maitiro ekugadzirisa 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. Mamiriro ayo ehunyanzvi ndeaya: Organic musanganiswa we "Motokari inopedza gasi yekudzora system yekuongorora uye kugadzirisa zvinhu" uye yechinyakare injini yekugadzirisa nzira dzekugadzirisa dzechinyakare injini yenguva dzose nzira dzekugadzirisa haigone kuzadzisa zvinodiwa zvemazuva ano ekuchengetedza injini kukanganisa, Iyo passive mhinduro kudambudziko reabnormal mashandiro eemission control system yeinjini yekudzivirira kwezvakatipoteredza ichachinjirwa kune inoshanda yekudzivirira yeabnormal system yekudzivirira injini yekudzivirira.

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.
