Musimboti wekushanda wetatu-nzira inoshandura inoshandura ndeye: kana tembiricha yakakwira yemotokari inopera kuburikidza nemudziyo wekunatsa, iyo inonatsa mune matatu-nzira inoshandura inoshandura inosimudzira chiitiko chemhando nhatu dzegasi CO, hydrocarbons uye NOx, kusimudzira oxidation yayo - kuderedza kemikari maitiro, umo iyo CO oxidation pakupisa kwepamusoro inova isina ruvara, isiri-chepfu kabhoni dhaidhiyo gasi; Hydrocarbons oxidize kumvura (H2O) uye kabhoni dhaikisaidhi pakudziya kwakanyanya; NOx inoderedzwa kuita nitrogen uye oksijeni. Mhando nhatu dzegasi rinokuvadza kuita gasi risingakuvadzi, kuitira kuti enhi yemotokari icheneswe. Tichifunga kuti kuchine okisijeni iripo, mwero wemafuta emhepo unonzwisisika.
Nekuda kwehuhu husina kunaka huzhinji muChina, mafuta acho ane sarufa, phosphorus uye antiknock agent MMT ine manganese. Izvi zvinoumba makemikari zvinoumba maumbirwo emakemikari pamusoro peiyo okisijeni sensor uye mukati meiyo nzira nhatu-catalytic converter ine exhaust gasi inoburitswa mushure mekupisa. 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 chiyero muimba yekupisa asi haigoni kuora uye kupisa, saka nekubuda kwegasi remarara, tsvina iyi ichaiswawo pamusoro peiyo okisijeni sensor uye matatu-nzira inoshandura inoshandura. Imhaka yezvikonzero zvakawanda zvinoita kuti mota mushure mekutyaira kwechinguva chemamaira, mukuwedzera kune kabhoni kuunganidzwa muvharuvhu yekudya uye mukamuri yekupisa, zvinokonzeresa iyo okisijeni sensor uye nzira nhatu-catalytic inoshandura chepfu kutadza, nzira nhatu. catalytic converter blockage uye EGR vharafu yakavharwa nesediment yakanamatira uye kumwe kutadza, zvichikonzera kushanda kweinjini zvisina kujairika, zvichikonzera kuwedzera kushandiswa kwemafuta, kuderera kwesimba uye kupera simba kunodarika mwero uye mamwe matambudziko.
Injini yechinyakare gadziriso inogumira kune yekutanga kuchengetedza kwe lubrication system, yekutora system uye mafuta ekupa system, asi haigone kuzadzisa zvizere zvekugadzirisa zvinodiwa zvemazuva ano injini lubrication system, intake system, mafuta ekupa system uye exhaust system, kunyanya zvinodiwa zvekuchengetedza. emission control system. Nokudaro, kunyange kana motokari kwenguva yakareba yekugadzirisa, zvakaoma kudzivisa matambudziko ari pamusoro apa.
Mukupindura kuzvikanganiso zvakadaro, matanho anotorwa nemabhizinesi ekugadzirisa anowanzo kutsiva okisijeni sensors uye matatu-nzira inoshandura inoshandura. Nekudaro, nekuda kwedambudziko rekutsiva mutengo, kukakavara pakati pemabhizinesi ekugadzirisa nevatengi kunoenderera. Kunyanya izvo zvisiri zvehupenyu hwesevhisi yekutsiviwa kweokisijeni sensors uye matatu-nzira catalytic vashanduri, kazhinji ndiyo inotariswa nekukakavadzana, vatengi vazhinji vakatoti dambudziko iri kumhando yemota.
