Sensor yoyenda mpweya - imodzi mwamasensa ofunikira a injini ya EFI.
Electronic control petrol jekeseni injini kuti mupeze ndende yabwino kwambiri yosakaniza pansi pazikhalidwe zosiyanasiyana zogwirira ntchito, ndikofunikira kuyeza kuchuluka kwa mpweya womwe umalowetsedwa mu injini nthawi iliyonse, womwe ndiye maziko akulu a ECU kuwerengera (kuwongolera) kwamafuta. jekeseni. Ngati mpweya otaya sensa kapena mzere akulephera, ndi ECU sangapeze olondola kudya mpweya chizindikiro, sangathe kulamulira kuchuluka kwa jekeseni bwinobwino, zomwe zingachititse kusakaniza kukhala wandiweyani kapena woonda kwambiri, kuti injini si kuthamanga bwinobwino. . Pali mitundu yambiri ya masensa otaya mpweya pamagetsi kulamulira dongosolo mafuta jekeseni, ndi wamba mpweya otaya masensa akhoza kugawidwa mu tsamba (mapiko) mtundu, pachimake mtundu, otentha waya mtundu, otentha filimu mtundu, Karman vortex mtundu ndi zina zotero.
Mitundu 5 ya zolakwika za sensa ya mpweya
Sensa yoyendetsa mpweya ndi gawo lofunikira pakuwongolera injini zamagalimoto, kulephera kwake kumabweretsa kuwonongeka kwa injini, kuchuluka kwamafuta, komanso kukhudza chitetezo chagalimoto. Zolakwika zisanu zodziwika bwino za masensa akuyenda kwa mpweya ndi mawonekedwe ake ndi awa:
Kuthamanga kwamphamvu kwa mpweya ndi mphamvu yamagetsi: izi zingayambitse kuthamanga kosagwira ntchito, kuthamanga kofooka, kuchuluka kwa mafuta ndi mavuto ena.
Mpweya wonse wamagetsi ndi wokwera kwambiri kapena wotsika kwambiri : Izi zikusonyeza kuti sensa ikhoza kukhala yosayesa kuthamanga kwabwino, zomwe zingakhudze momwe injini ikuyendera.
Kusakaniza kwa gasi woonda kwambiri kapena wandiweyani kwambiri : Izi zitha kupangitsa injini kusagwira ntchito bwino, kuthamanga mofooka, kuchuluka kwamafuta komanso kutulutsa kwamphamvu.
Chizindikiro cholakwika, kusokoneza kwa ma siginecha kapena kusakhazikika kwa ma sign : Mavutowa atha kuyambitsa jakisoni wochuluka kapena wocheperako, zomwe zimakhudza momwe injini ikuyendera.
Ngati gawo la fyuluta ya mpweya silinasinthidwe kwa nthawi yayitali kapena kugwiritsa ntchito chinthu chochepa kwambiri cha fyuluta, zidzachititsa kuti fumbi likhale mkati mwa sensa ya mpweya, zomwe zimakhudza kulondola kwake komanso moyo wautumiki.
Kuti muzindikire ndi kuthetsa zolakwika izi, njira zotsatirazi zitha kutengedwa:
Yezerani kuchuluka kwa voliyumu ya injini yomwe ikuyenda : mu malo osagwira ntchito a injini, mphamvu yamagetsi yamagetsi yakumapeto kwa siginecha iyenera kukhala pakati pa 0.8 ndi 4V; Mukathamangitsa katundu wambiri, chizindikiro chamagetsi chiyenera kukhala pafupi ndi 4V.
Gwiritsani ntchito ma multimeter kuti muyese mphamvu yotulutsa sensa: mtengo wamagetsi wokhazikika uyenera kukhala 5V, mutha kuyesa kuyankha powombera mpweya mu sensa.
Chotsani pulagi yamagetsi ya sensa ya mpweya pamene injini ikuyenda : weruzani ngati sensa ikugwira ntchito bwino powona kusintha kwa injini.
Gwiritsani ntchito chida chodziwira zolakwika kuti muwerenge nambala yolakwika: ndipo gwirani cholakwacho molingana ndi nambala yolakwika yomwe ikuwonetsedwa.
Ngati sensor yoyendetsa mpweya ikupezeka kuti ndi yolakwika, iyenera kukonzedwa kapena kusinthidwa munthawi yake kuti ipewe kukhudzidwa kwakukulu pakugwira ntchito kwa injini.
Njira yokonzanso sensa ya mpweya
Njira zokonzetsera za masensa akuyenda kwa mpweya zimaphatikizapo kuyang'anira ndi kuyeretsa, kusinthira sensa, kukonza magawo owonongeka, ndi kuyendera kwathunthu. pa
Yang'anani ndikuyeretsa sensa ya mpweya: nthawi ndi nthawi onetsetsani kuti chingwe cholumikizira cha sensa ya mpweya ndi yotayirira kapena yawonongeka. Ngati vuto linalake lapezeka, likonzeni kapena musinthe munthawi yake. Nthawi yomweyo, kuyeretsa sensa ya mpweya wotuluka kumatha kuwongolera bwino kulondola kwake. Gwiritsani ntchito chida chapadera chochotsera sensa, kuyeretsa ndi chotsuka chokhala ndi luso loyeretsa bwino, pukutani mukatha kuyeretsa ndikuyiyika pa.
Bwezerani mpweya wotuluka : Ngati mpweya wa mpweya wokhawokha ulephera, sensa yatsopano iyenera kusinthidwa. Izi nthawi zambiri zimaphatikizapo kuchotsa sensor yoyambirira ndikuyika ina.
Konzani mbali zowonongeka : Ngati waya wotentha kapena kutentha kwa sensa ya mpweya watenthedwa, kusweka, kapena kuipitsidwa, muyenera kusintha gawo lolakwika. Izi zingaphatikizepo kusintha mawaya otentha, nkhungu zotentha, kapena kuyeretsa pamwamba pa sensor kuti muchotse fumbi ndi dothi.
Kuyendera kwathunthu : Ngati pali vuto ndi mita yoyendetsa mpweya, ndi bwino kuyang'anitsitsa kwathunthu, chifukwa vutoli likhoza kukhala ndi zovuta zambiri za dongosolo. Ngati pali vuto ndi mita yoyendetsa mpweya, kukonzanso sikungakhale kodalirika monga kusinthanitsa ndi gawo latsopano lofananira.
Mwachidule, sensa ya mpweya ndiyofunikira kuti injini igwire bwino ntchito, ndipo iyenera kuchitidwa panthawi yomwe ikulephera kuwonetsetsa kuti ntchito ya injini ndi mpweya zimakwaniritsa miyezo.
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.
