Inaliti yanamhlanje kunye neenjini zedizili zisebenzisa iinkqubo zolawulo ezinezivamvo ezininzi ezibeka iliso kwiiparamitha ezininzi.Phakathi kwee-sensor, indawo ekhethekileyo ihlala kwi-sensor yesigaba, okanye i-sensor ye-camshaft position.Funda malunga nemisebenzi, uyilo kunye nokusebenza kwale nzwa kwinqaku.
Yintoni inzwa yesigaba
I-sensor yesigaba (DF) okanye i-camshaft position sensor (DPRV) yinzwa yenkqubo yokulawula i-injection petroli kunye neenjini ze-diesel ezibeka esweni indawo yokuhambisa igesi.Ngoncedo lwe-DF, ukuqala komjikelezo we-injini kunqunywe yi-cylinder yayo yokuqala (xa i-TDC ifikelelwe) kunye nenkqubo ye-injection yesigaba iphunyeziwe.Le nzwa ixhunyiwe ngokusebenzayo kwi-sensor ye-crankshaft (DPKV) - inkqubo yokulawula injini ye-elektroniki isebenzisa ukufundwa kwezinzwa zombini, kwaye, ngokusekelwe kule nto, ivelisa i-pulses ye-injection ye-fuel kunye nokutshisa kwi-cylinder nganye.
Ii-DFs zisetyenziswa kuphela kwiinjini zepetroli ezinenaliti esasazwa ngezigaba kunye nakwezinye iindidi zeenjini zedizili.Kwaye ngumbulelo kwi-sensor ukuba owona mgaqo wenaliti yesigaba uphunyezwa ngokulula, oko kukuthi, inaliti yamafutha kunye nokutshisa kwi-cylinder nganye, kuxhomekeke kwindlela yokusebenza kwe-injini.Akukho mfuneko ye-DF kwiinjini ze-carburetor, ekubeni umxube we-fuel-air unikezelwa kwiisilinda ngokusebenzisa i-manifold eqhelekileyo, kwaye ukutshisa kulawulwa ngokusebenzisa i-distributor okanye i-sensor isikhundla se-crankshaft.
I-DF ikwasetyenziswa kwiinjini ezinenkqubo yevalvu eguquguqukayo.Kule meko, ii-sensor ezihlukeneyo zisetyenziselwa ii-camshafts ezilawula i-valve yokungena kunye nokukhupha, kunye neenkqubo zokulawula eziyinkimbinkimbi kunye neendlela zabo zokusebenza.
Uyilo lwezinzwa zesigaba
Okwangoku, i-DF esekwe kwisiphumo seHolo isetyenziswa - ukwenzeka komahluko onokuthi ubekho kwi-wafer ye-semiconductor apho umsinga othe ngqo uhamba khona xa ubekwe kumhlaba wemagnethi.Iinzwa zempembelelo zeholo ziphunyezwa ngokulula.Isekelwe kwisikwere okanye kwi-rectangular semiconductor wafer, kumacala amane apho abafowunelwa baxhunyiwe - igalelo ezimbini, ukubonelela ngoku ngokuthe ngqo, kunye neemveliso ezimbini, zokususa umqondiso.Ukuze kube lula, olu yilo lwenziwe ngendlela ye-chip, efakwe kwi-sensor yezindlu kunye ne-magnet kunye nezinye iindawo.
Kukho iindidi ezimbini zoyilo lwezinzwa zesigaba:
-Ifakwe;
- Isiphelo (intonga).
Slit isivamvo
Isiphelo soluvo
I-sensor ye-slotted phase ine-U-shape, kwicandelo layo kukho indawo yokubhekisela (umakishi) ye-camshaft.Umzimba we-sensor wahlulwe ube ngamacandelo amabini, kwelinye kukho imagnethi esisigxina, okwesibini kukho into enovakalelo, kuzo zombini iindawo kukho i-magnetic cores yesimo esikhethekileyo, esibonelela ngotshintsho kwintsimi yamagnetic ngexesha Ukugqitha komgangatho.
I-sensor yokugqibela inesimo se-cylindrical, i-camshaft reference point idlula phambi kokuphela kwayo.Kule nzwa, into yokuva ifumaneka ekupheleni, ngaphezu kwayo kukho imagnethi esisigxina kunye ne-magnetic cores.
Kufuneka kuqatshelwe apha ukuba i-sensor ye-camshaft ye-sensor ibalulekile, oko kukuthi, idibanisa i-signal sensing element echazwe ngasentla kunye ne-converter yesignali yesibini eyandisa umqondiso kwaye iyiguqule ibe yifom elungele ukuqhutyelwa yinkqubo yokulawula i-elektroniki.I-transducer ngokuqhelekileyo yakhiwe ngokuthe ngqo kwi-sensor, eyenza lula kakhulu ukufakela kunye nokucwangciswa kwenkqubo yonke.
Umgaqo-siseko wokuSebenza weSigaba soVavanyo
I-sensor yesigaba idibene ne-master disc efakwe kwi-camshaft.Le diski inendawo yokubhekisela yoyilo olunye okanye enye, edlula phambi kwenzwa okanye kwisithuba sayo ngexesha lokusebenza kwe-injini.Xa udlula phambi kwenzwa, indawo yesalathiso ivala imigca yamagnetic ephuma kuyo, ekhokelela kutshintsho kwintsimi yamagnetic ewela into enovakalelo.Ngenxa yoko, impembelelo yombane yenziwa kwi-sensor yeHolo, eyandisiweyo kwaye yatshintshwa ngumguquli, kwaye yondliwe kwiyunithi yokulawula injini ye-elektroniki.
Kwi-slotted sensors kunye nesiphelo, iidiski eziphambili zoyilo ezahlukeneyo zisetyenziswa.Idityaniswe kunye neenzwa ezifakiweyo, idiski ene-gap yomoya isebenza - i-pulse yokulawula yenziwa xa udlula le gap.Idityaniswe ne-sensor yokuphela, i-disk enamazinyo okanye i-benchmarks emfutshane isebenza - impembelelo yokulawula yenziwa xa i-benchmark idlula.
