Majekiseni emazuva ano uye injini dzedhiziri dzinoshandisa masisitimu ekudzora ane akawanda masensa anotarisisa akawanda emaparamita.Pakati pemasensa, nzvimbo yakakosha inogarwa nechikamu sensor, kana camshaft chinzvimbo sensor.Verenga nezve mabasa, dhizaini uye kushanda kweiyi sensor mune chinyorwa.
Chii chinonzi phase sensor
Phase sensor (DF) kana camshaft chinzvimbo sensor (DPRV) inzwa yekudzora sisitimu yejekiseni peturu uye dizeli injini inotarisisa chinzvimbo chegasi rekugovera michina.Nekubatsirwa kweDF, kutanga kwejini kutenderera kunotsanangurwa necylinder yayo yekutanga (apo TDC yasvika) uye chirongwa chejekiseni chinoitwa.Iyi sensor inoshanda yakabatana neiyo crankshaft position sensor (DPKV) - iyo yemagetsi injini manejimendi system inoshandisa kuverenga kwemasensa ese ari maviri, uye, zvichibva pane izvi, inogadzira pulses yejekiseni yehuni uye kupisa mucylinder yega yega.
MaDF anoshandiswa chete pamainjini epeturu ane jekiseni rakapatsanurwa uye pane mamwe marudzi einjini dzedhiziri.Uye iko kuvonga kune sensor kuti iyo iyo musimboti wejekiseni wakaiswa unonyanya kuitiswa, ndiko kuti, jekiseni remafuta uye kupisa kwecylinder yega yega, zvichienderana neinjini inoshanda modhi.Iko hakuna kudikanwa kweDF muinjini dzecarburetor, sezvo musanganiswa wemafuta-mhepo unopihwa kumasilinda kuburikidza neyakajairwa manifold, uye kupisa kunodzorwa uchishandisa muparadzi kana crankshaft chinzvimbo sensor.
DF inoshandiswawo painjini dzine vhezheni yenguva yenguva.Muchiitiko ichi, ma sensors akaparadzana anoshandiswa kune camshafts anodzora mavharuvhu ekutora uye ekupera, pamwe chete neakawanda akaomarara ekudzora masisitimu uye maitiro avo ekushandisa.
Dhizaini yechikamu sensors
Parizvino, DF yakavakirwa paHoro mhedzisiro inoshandiswa - kuitika kwemusiyano ungangoita mune semiconductor wafer kuburikidza iyo yakananga ikozvino inoyerera kana yaiswa mune remagineti.Hall effect sensors inoitwa zviri nyore.Iyo yakavakirwa pachikwere kana rectangular semiconductor wafer, kune mativi mana ayo anobatana akabatana - maviri ekuisa, ekupa yakananga ikozvino, uye maviri anobuda, ekubvisa chiratidzo.Kuti zvive nyore, dhizaini iyi inogadzirwa muchimiro chechip, icho chinoiswa mu sensor housing pamwe chete nemagineti nezvimwe zvikamu.
Kune maviri edhizaini marudzi echikamu sensors:
-Slotted;
- Kupera (tsvimbo).
Slit sensor
End sensor
Iyo slotted phase sensor ine U-shape, muchikamu chayo pane referensi point (marker) yecamshaft.Muviri we sensor wakakamurwa kuita hafu mbiri, mune imwe mune magineti isingaperi, mune yechipiri kune chinhu chinonzwisa tsitsi, muzvikamu zviviri izvi kune magineti cores echimiro chakakosha, chinopa shanduko musimba remagineti panguva chikamu chebhenji.
Iyo yekupedzisira sensor ine cylindrical chimiro, iyo camshaft reference point inopfuura pamberi pekuguma kwayo.Mune iyi sensor, chinhu chekunzwa chiri kumagumo, pamusoro payo inogara magineti uye magineti cores.
Izvo zvinofanirwa kucherechedzwa pano kuti camshaft chinzvimbo sensor yakakosha, ndiko kuti, inosanganisa chiratidzo chekunzwa chinotsanangurwa pamusoro uye chechipiri chiratidzo chinoshandura chinokudza chiratidzo uye chinochishandura kuita chimiro chakanakira kugadziriswa nemagetsi control system.Iyo transducer inowanzo vakwa yakananga mukati me sensor, iyo inorerutsa zvakanyanya kuisirwa uye kumisikidzwa kweiyo system yese.
Kushanda Nheyo yePase Sensor
Iyo phase sensor yakapetwa ne master disc yakaiswa pane camshaft.Iri dhisiki rine referensi poindi yeimwe dhizaini kana imwe, iyo inopfuura pamberi pe sensor kana mugomba rayo panguva yekushanda kweinjini.Kana ichipfuura pamberi pe sensor, nzvimbo yekunongedza inovhara mitsara yemagineti inobuda mairi, iyo inotungamira kune shanduko mune iyo magineti inoyambuka iyo inonzwa chinhu.Somugumisiro, simba remagetsi rinogadzirwa muHoro sensor, iyo inowedzerwa uye inoshandurwa neinoshandura, uye inodyiswa kumagetsi ekugadzirisa injini.
Kune slotted uye kupera sensors, master discs eakasiyana magadzirirwo anoshandiswa.Yakabatanidzwa neyakavharwa sensors, dhisiki ine gap remhepo inoshanda - iyo control pulse inoumbwa kana ichipfuura gap iri.Yakabatanidzwa ne sensor yekupedzisira, dhisiki ine mazino kana mapfupi mabhenji anoshanda - iyo control impulse inoumbwa kana bhenji inopfuura.
