Izinjini zesimanje zomjovo nodizili zisebenzisa amasistimu okulawula anezinzwa eziningi eziqapha inqwaba yamapharamitha.Phakathi kwezinzwa, indawo ekhethekile ithathwa inzwa yesigaba, noma inzwa yesikhundla se-camshaft.Funda mayelana nemisebenzi, ukwakheka nokusebenza kwale nzwa esihlokweni.
Iyini inzwa yesigaba
Inzwa yesigaba (DF) noma i-camshaft position sensor (DPRV) iyinzwa yohlelo lokulawula lomjovo kaphethiloli kanye nezinjini zikadizili eziqapha indawo yomshini wokusabalalisa igesi.Ngosizo lwe-DF, ukuqala komjikelezo wenjini kunqunywa isilinda sayo sokuqala (lapho i-TDC ifinyelelwa) kanye nohlelo lomjovo wezigaba luyasetshenziswa.Le nzwa ixhumeke ngokusebenza ku-crankshaft position sensor (DPKV) - uhlelo lokuphatha injini ye-elekthronikhi lusebenzisa ukufundwa kwazo zombili izinzwa, futhi, ngokusekelwe kulokhu, lukhiqiza ama-pulses omjovo kaphethiloli kanye nokuthungela kusilinda ngasinye.
Ama-DF asetshenziswa kuphela ezinjinini zikaphethiloli ezinomjovo wezigaba osabalalisiwe nakwezinye izinhlobo zezinjini zikadizili.Futhi kungenxa yenzwa ukuthi isimiso sokujova ngezigaba sisetshenziswa kalula, okungukuthi, umjovo kaphethiloli kanye nokuthungela ku-cylinder ngayinye, kuye ngokuthi imodi yokusebenza yenjini.Asikho isidingo se-DF ezinjini ze-carburetor, njengoba ingxube ye-fuel-air inikezwa kumasilinda ngokusebenzisa i-manifold evamile, futhi ukuthungela kulawulwa kusetshenziswa umsabalalisi noma inzwa yendawo ye-crankshaft.
I-DF iphinde isetshenziswe ezinjinini ezinesistimu ye-valve eguquguqukayo.Kulokhu, izinzwa ezihlukene zisetshenziselwa ama-camshafts alawula ama-valve wokungenisa nokukhipha, kanye nezinhlelo zokulawula eziyinkimbinkimbi kanye nezinhlelo zabo zokusebenza.
Ukuklanywa kwezinzwa zesigaba
Njengamanje, i-DF esekelwe kumphumela weHholo isetshenziswa - isenzakalo somehluko ongaba khona ku-wafer ye-semiconductor lapho kugeleza khona okuqondile lapho ibekwe endaweni kazibuthe.Izinzwa zomphumela wehholo zisetshenziswa kalula.Isekelwe ku-wafer ye-semiconductor eyisikwele noma engunxande, ezinhlangothini ezine lapho othintana nabo baxhunywe khona - okokufaka okubili, ukuhlinzeka okwamanje okuqondile, nokukhipha okubili, ukukhipha isignali.Ukuze kube lula, lo mklamo wenziwa ngendlela ye-chip, efakwe endlini yezinzwa kanye nozibuthe nezinye izingxenye.
Kunezinhlobo ezimbili zokuklama zezinzwa zesigaba:
-Slot;
- Qeda (induku).
Slit inzwa
Inzwa yokuqeda
Inzwa yesigaba esifakiwe ine-U-shape, esigabeni sayo kukhona indawo yokubhekisela (umaka) we-camshaft.Umzimba wenzwa uhlukaniswe ngama-halves amabili, kwelinye kukhona uzibuthe unomphela, okwesibili kukhona isici esibucayi, kuzo zombili izingxenye kukhona ama-magnetic cores omumo okhethekile, ohlinzeka ngoshintsho endaweni yamagnetic ngesikhathi ukudlula kwebhentshimakhi.
Inzwa yokuphela inomumo we-cylindrical, iphuzu lereferensi le-camshaft lidlula ngaphambi kokuphela kwalo.Kule nzwa, i-elementi yokuzwa itholakala ekugcineni, ngaphezu kwayo kunozibuthe ongapheli kanye nama-magnetic cores.
Kumele kuqashelwe lapha ukuthi inzwa yendawo ye-camshaft ibalulekile, okungukuthi, ihlanganisa isici sokuzwa isignali esichazwe ngenhla kanye nesiguquli sesignali sesibili esikhulisa isignali futhi siyiguqule ibe ifomu elilungele ukucutshungulwa uhlelo lokulawula i-elekthronikhi.I-transducer ivamise ukwakhiwa ngqo ku-sensor, okwenza kube lula kakhulu ukufakwa nokucushwa kwalo lonke uhlelo.
Umgomo Wokusebenza Wenzwa Yesigaba
Inzwa yesigaba ihlanganiswe ne-master disc efakwe ku-camshaft.Le disc inephoyinti lokubhekisela lomklamo owodwa noma omunye, odlula phambi kwenzwa noma igebe layo ngesikhathi sokusebenza kwenjini.Uma udlula phambi kwenzwa, indawo eyireferensi ivala imigqa kazibuthe ephuma kuyo, okuholela ekushintsheni kwenkundla kazibuthe ewela isici esibucayi.Ngenxa yalokho, kukhiqizwa umfutho kagesi kunzwa yeHholo, ekhuliswa futhi ishintshwe yi-converter, futhi ifakwe kuyunithi yokulawula injini ye-elekthronikhi.
Ukuze uthole izinzwa ezifakiwe neziphetho, kusetshenziswa ama-master discs emiklamo ehlukene.Ihlanganiswe nezinzwa ezifakiwe, idiski enegebe lomoya isebenza - kwakhiwa i-control pulse lapho kudlula lesi sikhala.Ihlanganiswe nenzwa yokuphela, idiski enamazinyo noma amabhentshimakhi amafushane ayasebenza - umfutho wokulawula uyakhiwa lapho ibhentshimakhi idlula.
