Kodi sensa ya crankshaft ya galimoto imatanthauza chiyani?
Sensa ya crankshaft, yomwe imadziwikanso kuti sensa ya malo a crankshaft, ndi sensa yapakati mu dongosolo lowongolera zamagetsi la injini. Imagwiritsidwa ntchito kwambiri kuzindikira malo ozungulira a crankshaft, chizindikiro chapakati cha pisitoni, ndi liwiro la injini, ndipo imapereka deta yofunika kwambiri ku unit yowongolera injini (ECU) kuti ilamulire nthawi yoyatsira moto ndi nthawi yoyatsira mafuta. Mfundo yogwirira ntchito ya sensa ya crankshaft imadalira mtundu wake, womwe umaphatikizapo mtundu wa induction ya magnetic-electric, mtundu wa Hall effect, ndi mtundu wa photoelectric. Mtundu wa induction ya magnetic-electric umapanga zizindikiro kudzera mu induction ya electromagnetic, mtundu wa Hall effect umazindikira malo pogwiritsa ntchito kusintha kwa mphamvu ya Hall, ndipo mtundu wa photoelectric umatumiza chidziwitso kudzera mu kutsekeka kwa dzenje lowala ndi kusintha kwa chizindikiro cha photoelectric; masensawa nthawi zambiri amagwira ntchito limodzi ndi sensa ya malo a camshaft kuti adziwe molondola ngodya ya crankshaft ndi liwiro la angular, kuonetsetsa kuti nthawi yoyatsira moto ndi nthawi yoyatsira mafuta ndi yolondola. Ntchito yake ndi yofunika kwambiri, osati kungodziwa nthawi yoyatsira moto ndi mafuta, komanso kusanthula kusinthasintha kwa ngodya ya crankshaft kuti izindikire kusokonekera kwa injini ndikupereka chithandizo cha data chowongolera osagwira ntchito komanso kuwongolera kuphulika kwa mafuta. Pakukonza magalimoto, zolakwika zomwe zimachitika kawirikawiri pa sensa ya crankshaft zimaphatikizapo kutayika kwa chizindikiro kapena kusokoneza, zomwe zingayambitse mavuto pakuyamba kwa injini, kusakhazikika kwa ntchito, kapena kutayika kwa mphamvu; njira zodziwira nthawi zambiri zimaphatikizapo kuyang'ana kulumikizana kwa mawaya, zizindikiro zotulutsa, kapena mphamvu zotsutsana ndi sensa kuti zitsimikizire kuti zikugwira ntchito bwino.
Zolakwika zomwe zimachitika kawirikawiri pa sensa ya crankshaft ndi monga kutayika kwa chizindikiro kapena kusokoneza, zomwe zingayambitse mavuto pakuyamba kwa injini, kusakhazikika kwa ntchito, kapena kutayika kwa mphamvu; njira zodziwira nthawi zambiri zimaphatikizapo kuyang'ana kulumikizana kwa mawaya, zizindikiro zotulutsa kapena kukana kwa sensa kuti zitsimikizire kuti ikugwira ntchito bwino.
Kulephera kwa sensa ya crankshaft kungayambitse zizindikiro monga kulephera kwa injini kuyatsa, kuyatsa kosakhazikika komanso nthawi yoika mafuta, kugwedezeka kwa injini komanso kuzimitsa liwiro, ndi zina zotero, ndipo ndikofunikira kuyang'ana ndikuyisintha pakapita nthawi.
Zizindikiro zachilendo zoyambira ndi opaleshoni
Kulephera kwa sensa ya crankshaft kumakhudza mwachindunji nthawi yoyatsira ndi nthawi yopangira mafuta ya injini, ndipo kumaonekera motere:
Kuvuta kuyambitsa kapena kulephera kuyambitsa: Chifukwa chakuti sensa singathe kupereka chizindikiro cha malo a crankshaft, ECU (gawo lowongolera injini) silingathe kuwongolera kuyatsa ndi kulowetsa mafuta, zomwe zimapangitsa kuti nthawi yoyatsira iyambe kwa masekondi opitilira 5 kapena kulephera kuyatsa kangapo, ndipo pazochitika zazikulu, magetsi amphamvu ndi kulowetsa mafuta zimazimitsidwa.
Kugwedezeka kwa injini ndi kutayika kwa mphamvu:
Kusakhazikika: Liwiro la injini limasintha mosasinthasintha pakati pa 600-1200 rpm, ndipo kumveka bwino kwa chiwongolero cha chiwongolero n'koonekeratu.
Kuthamanga kofooka: Liwiro la injini ndi lovuta kupitirira 3000 rpm mukakwera, ndipo chitoliro chotulutsa utsi chingatulutse mawu otuluka kapena utsi woyera (chifukwa cha kuyaka kosakwanira).
Kuopsa kwa injini kuzimitsidwa poyendetsa: Kulephera kwadzidzidzi kwa mphamvu kungachitike poyendetsa galimoto mothamanga kwambiri, ndipo ECU imalowa mu njira yodzitetezera ndikuzimitsidwa mwamphamvu, zomwe ndi zoopsa kwambiri.
Ntchito za dongosolo ndi zizindikiro zochenjeza
Kulephera kwa dongosolo lamagetsi:
Ntchito monga kuyendetsa galimoto mozungulira, kuyimitsa galimoto yoyambira yokha, ndi kuletsa kutayikira kwa utsi zimayimitsidwa mwachindunji.
Nyali yolakwika imakhala yoyaka kapena yowala nthawi zonse, ndipo mitundu ina imayambitsa ma alarm olumikizirana a EPS/ABS.
Utsi woipa komanso kugwiritsa ntchito mafuta molakwika: Utsi woyera wopitirira muyeso wokhala ndi fungo lofanana ndi la petulo umatuluka, sensa ya okosijeni imanena kuti pali vuto la kusalinganika kwa mafuta, ndipo kugwiritsa ntchito mafuta kumawonjezeka kwambiri.
Kusiyana kwa zizindikiro za kuopsa kwa cholakwika
Vuto laling'ono: Galimotoyo ndi yofooka ikakwera phiri, mphamvu ya accelerator imachepa, koma mphamvu yake siisintha kwambiri.
Vuto lalikulu: Silingathe kuyatsa konse, ndipo mota ikhoza kupanga phokoso la pisitoni ikugunda valavu (mu mitundu yakale).
Pamene sensa ya injini ya crankshaft yalephera, galimotoyo iwonetsa zizindikiro monga kuyatsa kosazolowereka, kutaya mphamvu, kugwedezeka kwambiri, ndi kuwala kolakwika kuyaka, motere:
Kuyambitsa kwachilendo
Kutayika kwa chizindikiro cha sensa kungayambitse kuyatsa kosakhazikika komanso nthawi yojambulira mafuta, zomwe zimawonetsedwa motere:
Kuvuta kuyambitsa mozizira: Zimafunika kuyesa kangapo kuti kuyatsa kuyake, ndipo pakakhala zovuta kwambiri, sikungathe kuyambitsa konse.
Kuwonjezeka kwa nthawi yoyambira: Nthawi yozungulira injini ndi yayitali kwambiri, ndipo pakhoza kukhala phokoso losazolowereka.
Mavuto oyendetsa galimoto
Vutoli limayambitsa kusalingana kwa makina amagetsi, ndipo zizindikiro zofala zimaphatikizapo:
Kuthamanga kofooka: Kuyankha kwa kukwera kapena kudutsana ndi galimoto kumakhala pang'onopang'ono, ndipo chopondera cha accelerator chiyenera kuchepetsedwa mokwanira kuti chiwonjezere liwiro.
Kugwedezeka kosagwira ntchito: Injini imagwedezeka mwamphamvu ikayimitsidwa, ndipo chiwongolero kapena mpando zimakhala ndi phokoso loonekeratu.
Utsi woyera umatulutsa: Kuyaka kosakwanira kumapangitsa kuti utsi woyera utuluke kuchokera mu chitoliro chotulutsa utsi. Kuchuluka kwa kugwiritsa ntchito mafuta: Chifukwa cha kusalamulira bwino mafuta, kugwiritsa ntchito bwino mafuta kumachepa.
Kulephera kwa makina amagetsi
Zizindikiro zachilendo za sensor zimayambitsa unyolo:
Nyali ya injini pa dashboard imayatsa: Nyali ya injini pa dashboard imayatsa nthawi zonse kapena imawala.
Kulephera kwa ntchito: Makina oyendetsera sitima yapamadzi ndi mabuleki otulutsa utsi sangagwiritsidwe ntchito.
Kuopsa kwa injini kuzimitsa: Injini ikhoza kuzimitsa mwadzidzidzi ikuyendetsa galimoto mothamanga kwambiri, zomwe zingabweretse mavuto.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
