Imashini igezweho hamwe na moteri ya mazutu ikoresha sisitemu yo kugenzura hamwe na sensor nyinshi zikurikirana ibipimo byinshi.Mu byuma byifashishwa, ahantu hihariye hafashwe na sensor ya feri, cyangwa icyerekezo cya kamera.Soma ibyerekeye imikorere, igishushanyo nigikorwa cyiyi sensor mu ngingo.
Icyiciro cya sensor
Icyiciro cya sensor (DF) cyangwa icyuma cyerekana kamera (DPRV) ni sensor ya sisitemu yo kugenzura lisansi na moteri ya mazutu ikurikirana aho uburyo bwo gukwirakwiza gaze buhagaze.Hifashishijwe DF, intangiriro yizunguruka ya moteri igenwa na silinderi yayo ya mbere (iyo TDC igeze) hanyuma gahunda yo gutera inshinge ikurikizwa.Iyi sensor ihujwe neza na sensor ya crankshaft (DPKV) - sisitemu yo gucunga moteri ya elegitoronike ikoresha ibyasomwe byombi, kandi, ishingiye kuri ibi, itanga impiswi zo gutera lisansi no gutwika muri buri silinderi.
DF ikoreshwa gusa kuri moteri ya lisansi hamwe no gutera inshinge zagabanijwe no mubwoko bumwe na bumwe bwa moteri ya mazutu.Kandi tubikesha sensor ko ihame nyirizina ryo gutera inshinge zishyirwa mubikorwa byoroshye, ni ukuvuga gutera lisansi no gutwika kuri buri silinderi, bitewe nuburyo moteri ikora.Ntibikenewe DF muri moteri ya carburetor, kubera ko ivangwa rya lisansi-mwuka bitangwa kuri silinderi binyuze mumurongo umwe, kandi gutwika bigenzurwa hakoreshejwe ikwirakwiza cyangwa icyuma cyerekana imyanya.
DF nayo ikoreshwa kuri moteri hamwe na sisitemu yo guhinduranya igihe.Muri iki kibazo, ibyuma bitandukanye bikoreshwa kuri camshafts igenzura ibyinjira nogusohora imyuka, hamwe na sisitemu igenzura cyane hamwe na algorithm ikora.
Igishushanyo mbonera cya sensor
Kugeza ubu, DF ishingiye ku ngaruka za Hall irakoreshwa - kubaho kw'itandukaniro rishobora kuba muri wafer ya semiconductor unyuzamo umuyaga utaziguye iyo ushyizwe mumashanyarazi.Ibyuma byerekana ingoro bishyirwa mubikorwa byoroshye.Ishingiye kuri kare cyangwa urukiramende rwa semiconductor wafer, kumpande enye zifitanye isano - ibyinjijwe bibiri, byo gutanga amashanyarazi ataziguye, nibisohoka bibiri, kugirango bikureho ibimenyetso.Kugirango byorohe, iki gishushanyo gikozwe muburyo bwa chip, gishyirwa mumazu ya sensor hamwe na magneti nibindi bice.
Hariho uburyo bubiri bwo gushushanya ibyiciro bya sensor:
-Yashyizwe ahagaragara;
- Kurangiza (inkoni).
Rukuruzi
Rukuruzi
Icyerekezo cyerekana icyiciro gifite U-shusho, mugice cyayo hari aho yerekeza (marikeri) ya camshaft.Umubiri wa sensor igabanyijemo kabiri, murimwe hariho magneti ahoraho, mugice cya kabiri hari ikintu cyunvikana, mubice byombi harimo ibice bya magnetique bifite imiterere yihariye, bitanga impinduka mumashanyarazi mugihe cya Ibipimo.
Rukuruzi rwanyuma rufite ishusho ya silindrike, ingingo ya camshaft yerekanwe imbere yimpera yayo.Muri iyi sensor, ibintu byunvikana biherereye kumpera, hejuru ni magneti ahoraho hamwe na magnetiki.
Twabibutsa ko icyuma gifata ibyuma bifata amajwi ari ntangarugero, ni ukuvuga, gihuza ibimenyetso byerekana ibimenyetso byasobanuwe haruguru hamwe n’ibimenyetso bya kabiri bihindura ibimenyetso byongera ibimenyetso bikabihindura muburyo bworoshye bwo gutunganya na sisitemu yo kugenzura hakoreshejwe ikoranabuhanga.Transducer isanzwe yubatswe muburyo bwa sensor, yoroshya cyane kwishyiriraho no kugena sisitemu yose.
Ihame ry'akazi ry'icyiciro cya Sensor
Icyiciro cya sensor ihujwe na master master yashizwe kumashusho.Iyi disiki ifite aho yerekeza igishushanyo kimwe cyangwa ikindi, inyura imbere ya sensor cyangwa mu cyuho cyayo mugihe ikora moteri.Iyo unyuze imbere ya sensor, ingingo yerekanwe ifunga imirongo ya magneti isohoka muri yo, biganisha ku mpinduka mumurima wa rukuruzi wambukiranya ibintu byoroshye.Nkigisubizo, imbaraga zamashanyarazi zibyara muri sensor ya Hall, ikongerwaho kandi igahindurwa nuwayihinduye, ikagaburirwa ishami rishinzwe kugenzura moteri.
Kumurongo wanyuma no kurangiza, disiki nkuru yubushakashatsi butandukanye irakoreshwa.Ifatanije na sensororo ya disiki, disiki ifite icyuho cyumwuka ikora - pulse yo kugenzura ikorwa iyo inyuze icyuho.Hamwe na sensor ya nyuma, disiki ifite amenyo cyangwa ibipimo bigufi bikora - impulse yo kugenzura ikorwa mugihe igipimo cyanyuze.
