Sensa yoyendera mpweya - imodzi mwa masensa ofunikira a injini ya EFI.
Injini yojambulira mafuta yamagetsi kuti mupeze kuchuluka kwabwino kwa kusakaniza pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito, ndikofunikira kuyeza molondola kuchuluka kwa mpweya womwe umalowa mu injini nthawi iliyonse, chomwe ndi maziko akulu a kuwerengera kwa ECU (kuwongolera) kwa mafuta. Ngati sensa ya mpweya kapena mzere wa mpweya walephera, ECU singalandire chizindikiro choyenera cha mpweya wolowa, singayang'anire kuchuluka kwa jakisoni mwachizolowezi, zomwe zimapangitsa kuti chisakanizocho chikhale chokhuthala kwambiri kapena chochepa kwambiri, kotero kuti injiniyo siigwira ntchito mwachizolowezi. Pali mitundu yambiri ya masensa oyendera mpweya a dongosolo lojambulira mafuta lamagetsi, ndipo masensa oyendera mpweya wamba amatha kugawidwa m'magulu a blade (phiko), core type, hot wire type, hot film type, Karman vortex type ndi zina zotero.
Mitundu 5 ya zolakwika za sensa yoyendera mpweya
Sensa yoyendera mpweya ndi gawo lofunika kwambiri pa kayendetsedwe ka injini ya magalimoto, kulephera kwake kungayambitse kuchepa kwa magwiridwe antchito a injini, kuwonjezeka kwa kugwiritsa ntchito mafuta, komanso kukhudza chitetezo cha galimoto. Zolakwika zisanu zomwe zimafala kwambiri pa masensa oyendera mpweya ndi mawonekedwe awo ndi awa:
Kuyenda kwa mpweya ndi magetsi osazolowereka: izi zingayambitse liwiro losakhazikika, kuthamanga kofooka, kuchuluka kwa mafuta ndi mavuto ena.
Mphamvu yonse ya mpweya ndi yokwera kwambiri kapena yotsika kwambiri: Izi zikusonyeza kuti sensa singathe kuyeza kayendedwe ka mpweya molondola, zomwe zingakhudze magwiridwe antchito a injini.
Kusakaniza kwa mpweya wochepa kwambiri kapena wokhuthala kwambiri: Izi zingayambitse kulephera kwa injini, kuthamanga pang'ono, kugwiritsa ntchito mafuta ambiri komanso utsi wochuluka.
Chizindikiro cholakwika, kusokonezeka kwa chizindikiro kapena kusakhazikika kwa chizindikiro: Mavutowa angayambitse kulowetsedwa kwa mafuta ambiri kapena ochepa kwambiri, zomwe zimakhudza magwiridwe antchito abwinobwino a injini.
Ngati chinthu chosefera mpweya sichinasinthidwe kwa nthawi yayitali kapena kugwiritsa ntchito chinthu chosafunikira chosefera mpweya, izi zipangitsa kuti fumbi lizisonkhana mkati mwa sensa yoyendera mpweya, zomwe zimakhudza kulondola kwake komanso nthawi yogwirira ntchito.
Kuti azindikire ndi kuthetsa zolakwika izi, njira zotsatirazi zingagwiritsidwe ntchito:
Yesani deta ya voteji yotuluka ya injini yomwe ikugwira ntchito: mu mkhalidwe wopanda ntchito wa injini, voteji yosinthika ya chizindikiro cha pulagi iyenera kukhala pakati pa 0.8 ndi 4V; Mukathamanga kwambiri mpaka kufika pa katundu wonse, chizindikiro cha voteji chiyenera kukhala pafupi ndi 4V.
Gwiritsani ntchito multimeter kuti muyese mphamvu ya magetsi yotulutsa ya sensa: mphamvu yamagetsi yachibadwa iyenera kukhala 5V, mutha kuyesa yankho mwa kupumira mpweya mu sensa.
Chotsani pulagi yamagetsi ya sensa yoyendera mpweya pamene injini ikugwira ntchito: weruzani ngati sensa ikugwira ntchito bwino mwa kuwona kusintha kwa injini.
Gwiritsani ntchito chida chodziwira vuto kuti muwerenge khodi yolakwika : ndikugwira vutolo molingana ndi khodi yolakwika yomwe yawonetsedwa.
Ngati choyezera mpweya chapezeka kuti chili ndi vuto, chiyenera kukonzedwa kapena kusinthidwa nthawi yake kuti injini isakhudzidwe kwambiri.
Njira yokonzera sensa yoyendera mpweya
Njira zokonzera masensa oyendera mpweya zimaphatikizapo kuyang'anira ndi kuyeretsa, kusintha masensa, kukonza ziwalo zowonongeka, ndi kuwunika kwathunthu.
Yang'anani ndikuyeretsa sensa yoyendera mpweya: nthawi ndi nthawi onani ngati chingwe cholumikizira cha sensa yoyendera mpweya chatayika kapena chawonongeka. Ngati pali vuto lililonse, likonzeni kapena lisintheni nthawi yomweyo. Nthawi yomweyo, kuyeretsa sensa yoyendera mpweya kungathandize bwino kulondola kwake. Gwiritsani ntchito chida chapadera kuchotsa sensa, kuyeretsa ndi chotsukira chomwe chili ndi luso loyeretsa bwino, kupukuta mutatsuka kenako ndikuyiyika pa .
Sinthani sensa yoyendera mpweya: Ngati sensa yoyendera mpweya yalephera, sensa yatsopano iyenera kusinthidwa. Izi nthawi zambiri zimaphatikizapo kuchotsa sensa yoyambirira ndikuyika yatsopano.
Konzani ziwalo zowonongeka: Ngati waya wotentha kapena chotenthetsera cha sensa yoyendera mpweya chatenthedwa, chasweka, kapena chadetsedwa, muyenera kusintha gawo lolakwika. Izi zingaphatikizepo kusintha mawaya otentha, nkhungu zotentha, kapena kuyeretsa pamwamba pa sensa kuti muchotse fumbi ndi dothi lochuluka.
Kuyang'anira kwathunthu: Ngati pali vuto ndi mita yoyezera mpweya, ndi bwino kuyang'anira kwathunthu, chifukwa vutoli lingakhale ndi mavuto ovuta kwambiri pamakina. Ngati pali vuto ndi mita yoyezera mpweya, kukonza sikungakhale kodalirika monga kuisintha ndi gawo latsopano lofanana.
Mwachidule, sensa yoyendera mpweya ndi yofunika kwambiri pa ntchito ya injini, ndipo iyenera kuthetsedwa pakapita nthawi pamene pali kulephera kuonetsetsa kuti magwiridwe antchito a injini ndi mpweya woipa zikukwaniritsa miyezo .
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.
