Kukonza njira zitatu.
Kukonza mpweya m'njira zitatu kumatanthauza kusintha kwa mpweya woipa monga CO, HC ndi NOx kuchokera ku utsi wa galimoto kukhala carbon dioxide, madzi ndi nayitrogeni yopanda vuto kudzera mu okosijeni ndi kuchepetsa. Gawo lonyamula la chothandizira cha njira zitatu ndi chidutswa cha zinthu zadothi zokhala ndi mabowo, zomwe zimayikidwa mu chitoliro chapadera chotulutsa utsi. Chimatchedwa chonyamulira chifukwa sichichita nawo gawo la catalytic reaction yokha, koma chimaphimbidwa ndi zokutira zachitsulo zamtengo wapatali monga platinamu, rhodium, palladium ndi rare earths. Ndi chipangizo chofunikira kwambiri choyeretsera kunja chomwe chimayikidwa mu dongosolo lotulutsa utsi wa galimoto.
Mfundo yogwira ntchito ya chosinthira mphamvu cha magalimoto atatu ndi iyi: pamene utsi wotentha kwambiri wa galimoto umadutsa mu chipangizo choyeretsera, chotsukira chomwe chili mu chosinthira mphamvu cha magalimoto atatu chidzawonjezera ntchito ya mpweya wa CO, ma hydrocarbon ndi NOx, ndikuchilimbikitsa kuti chichitepo kanthu kena kochepetsa okosijeni, momwe CO imasungunuka kukhala mpweya wopanda utoto, wopanda poizoni wa carbon dioxide pa kutentha kwakukulu; Ma hydrocarbon amasungunuka kukhala madzi (H2O) ndi carbon dioxide pa kutentha kwakukulu; NOx imachepetsedwa kukhala nayitrogeni ndi mpweya. Mpweya woipa utatu umakhala mpweya wopanda vuto, kotero kuti utsi wotentha wa galimoto ukhoza kuyeretsedwa. Pokhapokha ngati pali mpweya wokwanira, chiŵerengero cha mpweya ndi mafuta n'choyenera.
Popeza mafuta ali ndi sulfure, phosphorous ndipo mankhwala oletsa kugogoda a MMT ali ndi manganese, zigawozi za mankhwala zimapanga ma chemical complexes pamwamba pa sensa ya okosijeni ndipo mkati mwa chosinthira mpweya wamagetsi cha njira zitatu ndi mpweya wotulutsa utsi utayaka. Kuphatikiza apo, chifukwa cha zizolowezi zoyipa za dalaivala zoyendetsa, kapena kuyendetsa galimoto kwa nthawi yayitali m'misewu yodzaza, injini nthawi zambiri imakhala yosakwanira kuyaka, zomwe zimapangitsa kuti carbon isungidwe mu sensa ya okosijeni ndi chosinthira mpweya wamagetsi cha njira zitatu. Kuphatikiza apo, madera ambiri mdziko muno amagwiritsa ntchito mafuta a ethanol, omwe ali ndi mphamvu yoyeretsa kwambiri, amayeretsa dothi m'chipinda choyatsira koma sangawole ndi kuyaka, kotero ndi mpweya wotulutsa utsi, dothi ili lidzayikidwanso pamwamba pa sensa ya okosijeni ndi chosinthira mpweya wamagetsi cha njira zitatu. Chifukwa cha zinthu zambiri, galimoto ikatha kuyendetsa galimoto kwa nthawi ndithu, kuwonjezera pa kusonkhana kwa kaboni mu valavu yolowera ndi chipinda choyaka moto, izi zingayambitsenso kulephera kwa sensa ya okosijeni ndi poizoni wa catalyst wa njira zitatu, kutsekeka kwa catalyst wa njira zitatu ndi valavu ya EGR yotsekedwa ndi matope ndi kulephera kwina, zomwe zimapangitsa kuti injini isagwire bwino ntchito, zomwe zimapangitsa kuti mafuta azigwiritsidwa ntchito kwambiri, mphamvu ichepe komanso utsi utuluke kuposa muyezo.
Kusamalira injini nthawi zonse kumangokhala kusamalira makina opaka mafuta, makina olowetsa mafuta ndi makina operekera mafuta, koma sikungakwaniritse zofunikira zonse zosamalira makina amakono opaka mafuta, makina olowetsa mafuta, makina operekera mafuta ndi makina otulutsa utsi, makamaka zofunikira zosamalira makina owongolera utsi. Chifukwa chake, ngakhale galimotoyo itasamalidwa bwino kwa nthawi yayitali, n'kovuta kupewa mavuto omwe ali pamwambapa.
Poyankha kulephera kotereku, njira zomwe makampani okonza zinthu amachita nthawi zambiri zimakhala kusintha masensa okosijeni ndi ma catalytic converters a njira zitatu, koma chifukwa cha vuto la ndalama zosinthira, mikangano pakati pa makampani okonza zinthu ndi makasitomala ikupitirira. Makamaka, masensa okosijeni ndi ma catalyst a njira zitatu omwe sanasinthidwe ndi moyo wawo wothandiza nthawi zambiri amakhala pakati pa mikangano, ndipo makasitomala ambiri amanena kuti vutoli limabwera chifukwa cha mtundu wa galimotoyo.
Pofuna kuthetsa vutoli komanso vuto la makampani opanga magalimoto, makampani okonza, madipatimenti oyang'anira kukonza ndi madipatimenti oteteza chilengedwe, mabungwe ofufuza asayansi oyenerera afufuza ndikupanga njira zatsopano zosamalira injini ndi ukadaulo kuti athetse zolakwika za njira zachikhalidwe zosamalira injini.
Zomwe zili mu ukadaulo watsopanowu ndi izi: pokonza nthawi zonse makasitomala, kuwonjezera pa kusintha mafuta ndi kukonza zosefera zitatuzi, kuyeretsa ndi kukonza chosinthira chamagetsi cha njira zitatu kumawonjezedwa. Zinthu zake zaukadaulo ndi izi: Kuphatikiza kwachilengedwe kwa "zowunikira ndi kukonza zinthu zoyendetsera utsi wa galimoto" ndi njira zachikhalidwe zosamalira nthawi zonse za injini kuti zibwezeretsedwe njira zachikhalidwe zosamalira nthawi zonse za injini sizingakwaniritse zofunikira za zolakwika zamakono zosamalira injini, Yankho lopanda ntchito ku vuto la magwiridwe antchito osazolowereka a makina owongolera utsi wa injini yoteteza chilengedwe lidzasinthidwa kukhala kupewa kugwira ntchito kosazolowereka kwa makina owongolera utsi wa injini yoteteza chilengedwe.
1, ngati pali kuwonongeka kwa makina, kutentha kwambiri, mtunda woposa makilomita 200,000, poizoni wa lead, kuyeretsa sikokwanira.
2, monga injini pakati pa kuyeretsa, nthawi yomweyo dulani payipi yolumikizira injini ndi zida, ndikutseka valavu yoyendetsera madzi. Yambitsaninso injini, itakhala yokhazikika, ikhoza kulumikizidwanso ndikusinthidwa.
3, yang'anani ngati kuchuluka kwa chisakanizocho kuli koyenera kuti muwonetsetse kuti madziwo akhoza kupumidwa mu inlet ya utsi.
4, kuyeretsa magawo atatu kuyenera kutsukidwa pambuyo pa throttle, nozzle yamafuta ndi chipinda choyaka.
5, panthawi yoyeretsa, liwiro losagwira ntchito siliyenera kukhala lokwera kwambiri kuti chosinthira chothandizira cha njira zitatu chisatenthe kwambiri.
6, musagwetse madzi oyeretsera pa utoto wa galimoto.
7, malo ogwirira ntchito kutali ndi komwe moto umachokera, amachita bwino ntchito yoyezera moto.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zomwe zikulandiridwa kugula.
