Njira zitatu zothandizira.
Njira zitatu za catalysis zimatanthawuza kutembenuka kwa mpweya woipa monga CO, HC ndi NOx kuchokera ku utsi wagalimoto kukhala mpweya woipa wa carbon dioxide, madzi ndi nayitrogeni kupyolera mu okosijeni ndi kuchepetsa. Chonyamulira gawo la chothandizira njira zitatu ndi chidutswa cha porous ceramic chuma, amene anaika mu chitoliro wapadera utsi. Imatchedwa chonyamulira chifukwa sichitenga nawo gawo pakuchitapo kanthu kothandizira, koma imakutidwa ndi zitsulo zamtengo wapatali monga platinamu, rhodium, palladium ndi rare earths. Ndilo chipangizo chofunikira kwambiri choyeretsera chakunja chomwe chimayikidwa muutsi wamagalimoto.
Mfundo yogwiritsira ntchito njira zitatu zosinthira chothandizira ndi: pamene mpweya wotentha kwambiri wa galimoto umadutsa pa chipangizo choyeretsera, choyeretsa mu chosinthira chothandizira chamagulu atatu chidzakulitsa ntchito ya mipweya itatu CO, ma hydrocarboni ndi NOx, ndikulimbikitsa kuti akumane ndi makutidwe ndi okosijeni-kuchepetsa mankhwala, momwe CO oxidized kukhala mpweya wopanda utoto, wopanda poizoni wa carbon dioxide pa kutentha kwakukulu; Ma hydrocarbons amapangidwa ndi okosijeni m'madzi (H2O) ndi carbon dioxide pa kutentha kwakukulu; NOx imachepetsedwa kukhala nitrogen ndi oxygen. Mipweya itatu yovulaza imakhala mpweya wopanda vuto, kotero kuti utsi wagalimoto utha kuyeretsedwa. Pongoganiza kuti oxygen ilipobe, chiŵerengero chamafuta a mpweya ndi choyenera.
Chifukwa mafutawa ali ndi sulfure, phosphorous ndi antiknock agent MMT ili ndi manganese, zigawo za mankhwalazi zimapanga mankhwala opangidwa ndi mankhwala pamwamba pa sensa ya okosijeni ndi mkati mwa njira zitatu zothandizira chosinthira ndi mpweya wotulutsa mpweya wotuluka 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. Kuonjezera apo, madera ambiri a dziko amagwiritsa ntchito mafuta a ethanol, omwe ali ndi mphamvu yoyeretsa kwambiri, amatsuka dothi mu chipinda choyaka moto koma sangathe kuwola ndikuwotcha, chifukwa chake ndi kutuluka kwa mpweya wotulutsa mpweya, zinyalalazi zidzayikidwanso pamoto. pamwamba pa sensa ya okosijeni ndi chosinthira chanjira zitatu chothandizira. Ndi chifukwa cha zinthu zambiri zomwe galimoto ikathamangitsidwa kwa nthawi ndithu, kuwonjezera pa kudzikundikira kwa carbon mu valavu yowonongeka ndi chipinda choyaka moto, zidzachititsanso kuti sensa ya okosijeni ndi njira zitatu zothandizira poizoni kulephera, atatuwo. -kutsekereza njira yotseketsa ndi valavu ya EGR yotsekedwa ndi matope ndi zolephera zina, zomwe zimapangitsa kuti injini isagwire bwino ntchito, zomwe zimapangitsa kuti mafuta azigwiritsidwa ntchito kwambiri, kuchepa kwa mphamvu ndi kutulutsa mpweya kupitirira muyezo.
Kukonzekera kwanthawi zonse kwa injini kumangokhala pakukonza koyambira, makina opangira mafuta ndi makina operekera mafuta, koma sikungakwaniritse zofunikira zonse pakukonza makina amakono opangira mafuta a injini, makina olowera, makina operekera mafuta ndi makina otulutsa, makamaka zofunika kukonza. ya dongosolo la emission control. Choncho, ngakhale galimotoyo imasungidwa bwino kwa nthawi yaitali, zimakhala zovuta kupewa mavuto omwe ali pamwambawa.
Poyankha kulephera kotereku, njira zomwe mabizinesi osamalira amachitira nthawi zambiri zimakhala zosinthira masensa a okosijeni ndi otembenuza njira zitatu, koma chifukwa cha vuto la ndalama zosinthira, mikangano pakati pa mabizinesi osamalira ndi makasitomala ikupitilira. Makamaka, masensa a okosijeni ndi njira zitatu zothandizira zomwe sizinasinthidwe ndi moyo wawo wothandiza nthawi zambiri zimakhala zotsutsana, ndipo makasitomala ambiri amanena kuti vutoli ndi khalidwe la galimoto.
Pofuna kuthana ndi mutuwu komanso zovuta kuthetsa vuto la mabizinesi opanga magalimoto, mabizinesi osamalira, madipatimenti oyang'anira kukonza ndi dipatimenti yoteteza zachilengedwe, mabungwe ofufuza asayansi oyenerera afufuza ndikupanga njira zatsopano zosungiramo injini ndi ukadaulo wa zolakwika za njira zachikhalidwe zokonza injini.
Zomwe zili muukadaulo watsopanowu ndi: pokonza makasitomala nthawi zonse, kuwonjezera pakusintha mafuta ndikukonza zosefera zitatu, kuyeretsa ndi kukonza chosinthira chanjira zitatu kumawonjezeredwa. Mawonekedwe ake aukadaulo ndi: Kuphatikizika kwachilengedwe kwa "kuwunika ndi kukonza makina oyendetsa gasi" ndi njira zama injini zanthawi zonse zopangira njira zama injini zanthawi zonse sizingakwaniritse zofunikira pakuwonongeka kwa injini zamakono, The passiv solution to vuto la magwiridwe antchito achilendo a injini yoteteza zachilengedwe lidzasinthidwa kukhala chitetezo chogwira ntchito bwino cha makina owongolera mpweya wa injini yoteteza chilengedwe.
1, ngati pali kuwonongeka kwa makina, sintering yotentha, mtunda wa makilomita oposa 200,000, poizoni wotsogolera, kuyeretsa sikuli kwakukulu.
2, monga injini pakati pa kuyeretsa, nthawi yomweyo kusagwirizana injini ndi zipangizo kugwirizana payipi, ndi kutseka otaya valavu. Yambitsaninso injini, yosagwira ntchito, imatha kulumikizidwanso ndikusinthidwa.
3, yang'anani ngati ndende yosakaniza ndiyoyenera kuwonetsetsa kuti madziwo amatha kulowetsedwa munjira yachifunga.
4, kuyeretsa magawo atatu kuyenera kutsukidwa pambuyo pa throttle, nozzle mafuta ndi chipinda choyaka moto.
5, panthawi yoyeretsa, liwiro lopanda pake lisakhale lalitali kwambiri kuti mupewe kutenthedwa kwa njira zitatu zosinthira chothandizira.
6, musagwetse madzi oyeretsera pa utoto wagalimoto.
7, malo ogwirira ntchito kutali ndi gwero lamoto, chitani ntchito yabwino yoyezera moto.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zolandiridwa kuti mugule.
