Mfundo ntchito ya njira zitatu chothandizira Converter ndi: pamene mkulu kutentha kwa galimoto utsi utsi kudzera chipangizo kuyeretsedwa, ndi purifier mu njira zitatu chothandizira Converter kumapangitsanso ntchito ya mitundu itatu ya mpweya CO, hydrocarbons ndi NOx, kulimbikitsa makutidwe ndi okosijeni ake - kuchepetsa mankhwala anachita, imene CO okosijeni pa mkulu kutentha mpweya umakhala wopanda utoto, mpweya woipa; Ma hydrocarbon oxidize m'madzi (H2O) ndi carbon dioxide pa kutentha kwakukulu; NOx imachepetsedwa kukhala nitrogen ndi oxygen. Mitundu itatu ya gasi woyipa kukhala gasi wopanda vuto, kuti utsi wagalimoto uyeretsedwe. Pongoganiza kuti oxygen ilipobe, chiŵerengero chamafuta a mpweya ndi choyenera.
Chifukwa cha kusakhala bwino kwamafuta ku China, mafutawa amakhala ndi sulfure, phosphorous ndipo antiknock agent MMT imakhala ndi manganese. Zigawo zamankhwala izi zimapanga ma complexes a mankhwala pamwamba pa sensa ya okosijeni ndi mkati mwa njira zitatu zosinthira chothandizira ndi mpweya wotulutsa mpweya womwe umatulutsidwa pambuyo pa kuyaka. Kuonjezera apo, chifukwa cha khalidwe loipa la dalaivala, kapena kuyendetsa galimoto kwa nthawi yaitali m'misewu yodzaza, injiniyo nthawi zambiri imakhala yosakwanira kuyaka, yomwe imapanga mpweya wa carbon mu sensa ya okosijeni ndi chosinthira chothandizira katatu. Komanso, madera ambiri a dziko ntchito Mowa petulo, amene ali amphamvu kuyeretsa kwenikweni, adzayeretsa sikelo mu chipinda kuyaka koma sangathe kuwola ndi kuwotcha, kotero ndi umuna wa zinyalala mpweya, dothi nawo waikamo pamwamba pa kachipangizo mpweya ndi njira zitatu chothandizira Converter. Ndi chifukwa cha zinthu zambiri zomwe zimapangitsa galimotoyo itayendetsa galimoto kwa nthawi yamtunda, kuwonjezera pa kuchuluka kwa mpweya mu valavu yowonongeka ndi chipinda choyaka moto, zidzachititsanso mpweya wa okosijeni ndi njira zitatu zothandizira poyizoni poyizoni, kutsekeka kwachitsulo chosinthira ndi EGR valavu yotsekedwa ndi zinyalala ndi zolephera zina, zomwe zimabweretsa kuwonongeka kwa mphamvu, kuchepa kwa mphamvu ndi kuwonjezereka kwa injini. mavuto ena.
Kukonzekera kwanthawi zonse kwa injini kumangokhala pakukonza zoyambira zokometsera, njira yolowera ndi njira yoperekera mafuta, koma sikungakwaniritse zofunikira zonse zokonzekera makina amakono opangira mafuta a injini, dongosolo lamadyedwe, makina operekera mafuta ndi dongosolo lotulutsa mpweya, makamaka zofunika pakukonza dongosolo lowongolera mpweya. Choncho, ngakhale galimoto yaitali yachibadwa kukonza, n'zovuta kupewa mavuto pamwamba.
Poyankha kulakwitsa kotereku, njira zomwe mabizinesi osamalira amachitira nthawi zambiri zimakhala zosinthira masensa a okosijeni ndi zosinthira njira zitatu. Komabe, chifukwa cha vuto la mtengo wosinthira, mikangano pakati pa mabizinesi okonza ndi makasitomala ikupitilirabe. Makamaka omwe sali ndi moyo wautumiki wa kusintha kwa masensa a okosijeni ndi otembenuza njira zitatu, nthawi zambiri amatsutsana, makasitomala ambiri amati vuto ndi khalidwe la galimoto.
