I-1, umsebenzi kunye nohlobo lwe-Camshaft Position Sensor (CPS), umsebenzi wayo kukuqokelela i-Camshaft ye-Angle signal ehambayo, kunye neyunithi yokulawula i-electronic input (ECU), ukwenzela ukugqiba ixesha lokucima kunye nexesha lokujova i-fuel. I-Camshaft Position Sensor (CPS) ikwabizwa ngokuba yi-Cylinder Identification Sensor (CIS), ukwenzela ukwahlula kwi-crankshaft Position Sensor (CPS), i-Camshaft position sensors imelwe ngokubanzi yiCIS. Umsebenzi we-sensor ye-camshaft kukuqokelela umqondiso wesimo se-camshaft yokusabalalisa igesi kwaye uyifake kwi-ECU, ukuze i-ECU ikwazi ukuchonga i-compression top of dead center ye-cylinder 1, ukwenzela ukuba kuqhutywe ngokulandelelana kwenaliti yamafutha, ulawulo lwexesha lomlilo kunye nolawulo lokuthotywa. Ukongeza, uphawu lwendawo yecamshaft lukwasetyenziselwa ukuchonga umzuzu wokuqala wokutshisa ngexesha lokuqalisa injini. Ngenxa yokuba isivamvo sendawo yecamshaft sinokuchonga ukuba yeyiphi icylinder piston eza kufikelela kwi-TDC, ibizwa ngokuba yi-cylinder recognition sensor.photoelectricIimpawu zesakhiwo se-Photoelectric crankshaft kunye ne-camshaft yoluvo lwendawo eveliswe yinkampani yakwa-Nissan iphuculwe ukusuka kumthengisi, ngakumbi ngediski yophawu (umqondiso we-rotor). ), i-generator yesignali, izixhobo zokusasaza, i-sensor yezindlu kunye ne-wire harness plug.I-disk yesignali yi-rotor ye-signal ye-sensor, ecinezelwe kwi-shaft ye-sensor. Kwindawo ekufutshane nomphetho wepleyiti yomqondiso ukwenza isithuba esifanayo se-radian ngaphakathi nangaphandle izangqa ezibini zemingxuma yokukhanya. Phakathi kwazo, i-ring yangaphandle yenziwe nge-360 imingxuma ebonakalayo (izithuba), kunye ne-interval radian 1. (I-Hole evulekileyo ibalwa kwi-0.5. , i-shading hole ibalwa kwi-0.5.), esetyenziselwa ukuvelisa ukujikeleza kwe-crankshaft kunye nesignali yesantya; Kukho imingxuma emi-6 ecacileyo (uxande L) kwindandatho yangaphakathi, kunye nekhefu le-radians engama-60. , isetyenziselwa ukuvelisa umqondiso we-TDC we-cylinder nganye, phakathi kwayo kukho uxande olunomphetho obanzi kancinane ixesha elide ukwenzela ukuvelisa uphawu lwe-TDC lwe-cylinder 1. Ijeneretha yomqondiso igxininiswe kwizindlu zoluvo, eziqulunqwe ngumqondiso weNe (isantya kunye I-Angle signal) i-generator, i-signal ye-G (uphawu oluphezulu lweziko elifileyo) ijeneretha kunye nesiphaluka sokucubungula umqondiso. Umqondiso we-Ne kunye ne-G signal generator zenziwe nge-diode ekhupha ukukhanya (i-LED) kunye ne-photosensitive transistor (okanye i-photosensitive diode), ii-LED ezimbini ezijongene ngqo nee-transistors ezimbini ze-photosensitive ngokulandelelanayo. (i-LED) kunye ne-photosensitive transistor (okanye i-photodiode). Xa umngxuma wokuhambisa ukukhanya kwidiski yomqondiso ujikeleza phakathi kwe-LED kunye ne-photosensitive transistor, ukukhanya okukhutshwe yi-LED kuya kukhanyisa i-photosensitive transistor, ngeli xesha i-photosensitive transistor ivuliwe, i-collecter yayo ye-output level ephantsi (0.1 ~ O. 3V); Xa inxalenye ye-shading yediski yomqondiso ijikeleza phakathi kwe-LED kunye ne-photosensitive transistor, ukukhanya okukhutshwe yi-LED ayikwazi ukukhanyisa i-photosensitive transistor, ngeli xesha i-photosensitive transistor inqunyulwe, isiphumo sayo somqokeleli ophezulu (4.8 ~ 5.2V). Ukuba idiski yesiginali iyaqhubeka nokujikeleza, umngxuma wokuhambisa kunye nenxalenye ye-shading iya kuguqula i-LED kwi-transmittance okanye shading, kwaye umqokeleli we-photosensitive transistor uya kukhupha amanqanaba aphezulu naphantsi. Xa i-axis ye-sensor ene-crankshaft kunye ne-camshaft ijikeleza kunye, umqondiso wokukhanya komngxuma kwipleyiti kunye nenxalenye yomthunzi phakathi kwe-LED kunye ne-photosensitive transistor iyajika, ipleyiti yokukhanya kwe-LED ye-pervious ekukhanyeni kunye nefuthe le-shading iya kutshintsha enye irradiation kwi-signal generator ye-photosensitive. i-transistor, i-sensor signal iveliswa kunye ne-crankshaft kunye ne-camshaft isikhundla esihambelana nesignali ye-pulse. Ekubeni i-crankshaft ijikeleza kabini, i-sensor shaft ijikeleza i-signal kanye, ngoko i-sensor ye-signal ye-G iya kuvelisa i-pulses ezintandathu. Isivamvo somqondiso we-Ne siya kuvelisa imiqondiso ye-pulse engama-360. Kuba isithuba se-radian somngxuma wokukhanya we-G siginali yi-60. Kwaye 120 ngokujikeleza kwe-crankshaft. Ivelisa umqondiso wempembelelo, ngoko uphawu lwe-G ludla ngokubizwa ngokuba yi-120. Isiqinisekiso sofakelo loyilo 120. Isiginali 70 phambi kweTDC. (BTDC70. , kunye nomqondiso oveliswe ngumngxuma ocacileyo kunye nobubanzi obuxande obude kancinane buhambelana no-70 ngaphambi kokuba iziko eliphezulu elifileyo le-injini ye-cylinder 1. Ukuze i-ECU ikwazi ukulawula i-engile yokutofa kwangaphambili kunye ne-Angle yokuvutha kwangaphambili. i-interval radian yi-1. (I-transparent hole ibalwa kwi-0.5. , i-shading hole ibalwa kwi-0.5.) , ngoko ke kumjikelo we-pulse nganye, inqanaba eliphezulu kunye ne-akhawunti yezinga eliphantsi le-1 ngokulandelelana, izibonakaliso ze-360 zibonisa ukujikeleza kwe-crankshaft 720. Nganye ukujikeleza kwe-crankshaft yi-120. , Inzwa ye-signal ye-G ivelisa uphawu olunye, i-sensor ye-signal ye-Ne ivelisa iimpawu ze-60. Uhlobo lwe-Magnetic induction i-sensor yesikhundla se-Magnetic inokwahlulwa ibe yintlobo yeHolo kunye nohlobo lwe-magnetoelectric , njengoko kubonisiwe kwi-Figure 1. Le yokugqibela isebenzisa umgaqo wokungeniswa kwamagnetic ukuvelisa izibonakaliso zesikhundla esine-amplitude yayo ihluka kunye nesantya ukusuka kumakhulu ama-millivolts ukuya kumakhulu e-volts, kwaye i-amplitude iyahluka kakhulu. Oku kulandelayo sisingeniso esineenkcukacha kumgaqo osebenzayo wesixhobo soluvo: Umgaqo wokusebenza weNdlela apho umgca wamandla ombane udlula khona ngumsantsa womoya phakathi kwepoleni yemagnethi esisigxina yeN kunye nerotor, izinyo elinqabileyo le-rotor, umsantsa womoya phakathi I-rotor izinyo elinqabileyo kunye nentloko yemagnethi ye-stator, intloko yemagnethi, ipleyiti yesikhokelo sozibuthe kunye nepoleni yemagnethi esisigxina. Xa i-rotor yomqondiso ijikeleza, i-gap yomoya kwi-circuit yamagnetic iya kutshintsha ngezikhathi ezithile, kwaye ukuchasana kwamagnetic kwi-circuit magnetic kunye ne-flux magnetic ngokusebenzisa intloko yekhoyili yesignali iya kutshintsha ngamaxesha. Ngokomgaqo wokungeniswa kwe-electromagnetic induction, amandla ombane atshintshanayo aya kunyanzelwa kwikhoyili yokuva.Xa i-rotor yesiginali ijikeleza ngaxeshanye, umsantsa womoya phakathi kwamazinyo e-rotor convex kunye nentloko yamagnetic iyancipha, ukungafuni kwesekethe kuyancipha, i-magnetic flux. ukwanda, izinga lokutshintsha kwe-flux liyenyuka (dφ/dt>0), kunye ne-electromotive force eyi-E ilungile (E>0). Xa amazinyo e-convex e-rotor esondele kumda wentloko yamagnetic, i-magnetic flux φ iyanda ngokukhawuleza, isantya sokutshintsha kwe-flux sikhulu [D φ/dt=(dφ/dt) Max], kunye ne-electromotive force e-E is elona liphezulu (E=Emax). Emva kokuba i-rotor ijikeleze ijikeleze indawo ye-B, nangona i-magnetic flux φ isakhula, kodwa izinga lokutshintsha kwe-magnetic flux liyancipha, ngoko i-electromotive force e-E iyancipha. kunye nomgca osembindini wentloko kazibuthe, nangona umsantsa womoya phakathi kwezinyo le-rotor convex kunye nentloko kazibuthe yeyona incinci, ukuxhathisa kwamagnetic kwisekethe yemagnethi yeyona incinci, kwaye i-magnetic flux φ yeyona inkulu, kodwa ngenxa yokuba i-flux ayikwazi ukuqhubeka nokunyuka, izinga lokutshintsha kwe-magnetic flux yi-zero, ngoko amandla e-electromotive eyenzelwe u-E ngu-zero. izinyo le-convex kunye nentloko yamagnetic iyanda, ukunyuka kwe-magnetic circuit kwanda, kwaye i-magnetic flux iyancipha (dφ/dt< 0), ngoko ke amandla e-electrodynamic e-E angalunganga. Xa izinyo le-convex lijikela kumda wokushiya intloko yamagnetic, i-magnetic flux φ iyancipha ngokukhawuleza, izinga lokutshintsha kwe-flux lifikelela kwinqanaba elibi [D φ/df=- (dφ/dt) Max], kunye ne-electromotive force e-E. ifikelela kwakhona kubuninzi obungalunganga (E = -emax) . Ngaloo ndlela kunokubonwa ukuba ngalo lonke ixesha i-rotor yomqondiso ijika izinyo le-convex, i-coil ye-sensor iya kuvelisa i-periodic alternating force electromotive, oko kukuthi, i-electromotive force ibonakala iphezulu kwaye ixabiso elincinci, i-coil ye-sensor iya kukhupha isignali yombane ehambelanayo. Inzuzo ebalaseleyo ye-sensor induction sensor kukuba ayifuni ukunikezelwa kwamandla angaphandle, imagnethi esisigxina idlala indima yokuguqula amandla omatshini kumandla ombane, kwaye amandla ayo ombane akayi kulahleka. Xa isantya se-injini sitshintsha, isantya sokujikeleza kwamazinyo e-convex e-rotor siya kutshintsha, kwaye izinga lokutshintsha kwe-flux kumbindi nalo liya kutshintsha. Okukhona isantya siphezulu, kokukhona sisiba sikhulu isantya sotshintsho, kokukhona siphezulu amandla e-electromotive induction kwi-coil sensor. Ekubeni umsantsa womoya phakathi kwamazinyo e-rotor convex kunye nentloko kazibuthe ichaphazela ngokuthe ngqo ukuxhathisa kwemagnethi yesekethe yemagnethi kunye nombane ophumayo i-sensor coil, i-gap yomoya phakathi kwamazinyo e-rotor convex kunye nentloko yamagnetic ayinakuguqulwa ngokuthanda kwayo. Ukuba i-gap yomoya iyatshintsha, kufuneka ilungiswe ngokuhambelana nezibonelelo. Umsantsa womoya ngokuqhelekileyo uyilwe ngaphakathi koluhlu lwe-0.2 ~ 0.4mm.2) i-Jetta, i-Santana imoto ye-magnetic induction crankshaft position sensor1) Iimpawu zesakhiwo se-sensor ye-crankshaft isikhundla: I-magnetic induction crankshaft position sensor ye-Jetta AT, i-GTX kunye ne-Santana 2000GSi ifakiwe. kwibhloko yesilinda kufuphi ne-clutch kwi-crankcase, equlunqwe ngokukodwa ngumqondiso wejenereyitha kunye nomqondiso we-rotor.Ijeneretha yomqondiso ibotshelelwe kwibhloko ye-injini kwaye iqulethe iimagnethi ezisisigxina, iikhoyili zokuva, kunye neeplagi zokubopha iintambo. Ikhoyili yokuziva ikwabizwa ngokuba yikhoyili yomqondiso, kwaye intloko kazibuthe incamathele kwimagnethi esisigxina. Intloko kazibuthe ichasene ngqo nohlobo lwedisk yezinyo uhlobo lwerotor efakwe kwi crankshaft, kwaye intloko kazibuthe idityaniswe nedyokhwe magnetic (ipleyiti yesikhokelo somagnetic) ukwenza iluphu yesikhokelo somagnetic. amazinyo amancinane, amazinyo amancinane angama-57 kunye nezinyo elinye elikhulu elilungelelanisiweyo kwisangqa salo. Izinyo elikhulu lilahlekile umqondiso wereferensi yemveliso, ehambelana ne-injini cylinder 1 okanye cylinder 4 compression TDC phambi kwe-engile ethile. Iiradians zamazinyo amakhulu zilingana namazinyo amabini aconvex kunye namazinyo amathathu amancinci. Kuba i-rotor yomqondiso ijikeleza kunye ne-crankshaft, kwaye i-crankshaft ijikeleza kanye (360). , i-rotor yomqondiso iphinda ijikeleze kanye (360). , ngoko i-Angle yokujikeleza i-crankshaft egcinwe ngamazinyo e-convex kunye neziphene zamazinyo kwi-circumference ye-rotor yomqondiso yi-360. ). , i-Angle ye-crankshaft ebalwe sisiphene esikhulu sezinyo yi-15. (2 x 3. + 3 x3. = 15). .2) imeko yokusebenza kwesivamvo sesivamvo secrankshaft: xa isivamvo sendawo ye-crankshaft ene-crankshaft ijikeleza, umgaqo wokusebenza we-sensor yamagnetic induction, umqondiso we-rotor nganye ujike izinyo eliconvex, ikhoyili yokuva izakuvelisa i-emf etshintshanayo ngamaxesha athile (amandla ombane wombane. kubuninzi kunye nobuncinci), i-coil ikhupha isignali yombane etshintshanayo ngokufanelekileyo. Ngenxa yokuba i-rotor yesignali ibonelelwe ngezinyo elikhulu ukuvelisa umqondiso wesalathiso, ngoko xa izinyo elikhulu lijika intloko yamagnetic, i-voltage yesignali ithatha ixesha elide, oko kukuthi, isignali yokuphuma sisignali ye-pulse ebanzi, ehambelana nayo. i-Engile ethile phambi kwe-cylinder 1 okanye i-cylinder 4 compression TDC. Xa i-electronic control unit (ECU) ifumana isignali ye-pulse ebanzi, inokwazi ukuba indawo ephezulu ye-TDC ye-cylinder 1 okanye i-4 iza. Ngokuphathelele indawo ye-TDC ezayo ye-cylinder 1 okanye i-4, kufuneka inqume ngokuhambelana negalelo lomqondiso kwi-sensor ye-camshaft. Ekubeni i-rotor yomqondiso inamazinyo angama-58 e-convex, i-coil ye-sensor iya kuvelisa izibonakaliso ze-58 ezitshintshanayo zombane kwi-revolution nganye ye-rotor yomqondiso (i-revolution enye ye-crankshaft ye-injini) . iipulses kwiyunithi yolawulo lwe-elektroniki (ECU). Ngoko ke, kuzo zonke iisignali ezingama-58 ezifunyenwe yi-sensor yendawo ye-crankshaft, i-ECU iyazi ukuba i-injini ye-crankshaft ijikeleze kanye. Ukuba i-ECU ifumana izibonakaliso ze-116000 kwi-sensor ye-crankshaft kwi-1min, i-ECU ingabala ukuba isantya se-crankshaft n yi-2000 (n=116000/58=2000)r/imvula; Ukuba i-ECU ifumana izibonakaliso ze-290,000 ngomzuzu ukusuka kwi-sensor ye-crankshaft isikhundla, i-ECU ibala i-crank speed ye-5000 (n= 29000/58 =5000)r/min. Ngale ndlela, i-ECU ingabala isantya sokujikeleza kwe-crankshaft ngokusekelwe kwinani leempawu ze-pulse ezifunyenwe ngomzuzu ukusuka kwi-sensor ye-crankshaft isikhundla. Isiginali yesantya se-injini kunye nophawu lomthwalo zezona zibonakaliso zibalulekileyo kunye nezisisiseko zolawulo lwenkqubo yolawulo lwe-elektroniki, i-ECU ingabala iiparitha ezintathu zolawulo ezisisiseko ngokwale miqondiso mibini: i-injection esisiseko yokusifa i-Angle (ixesha), i-Angle esisiseko yokutshisa (ixesha) kunye ne-ignition conduction. I-angle (i-coil yokutshisa i-primary current ngexesha) .I-Jetta AT kunye ne-GTx, i-Santana 2000GSi imoto ye-magnetic induction uhlobo lwe-crankshaft isikhundla senzwa ye-rotor ye-rotor eyenziwa ngumqondiso njengomqondiso wesalathiso, ulawulo lwe-ECU yexesha le-injection ye-fuel kunye nexesha lokucima isekelwe kwisignali eyenziwe. ngomqondiso. Xa i-ECu ifumana umqondiso oveliswe sisiphene esikhulu sezinyo, ilawula ixesha lokutshisa, ixesha lokutofa kwepetroli kunye nexesha eliphambili lokutshintsha kwekhoyili yokutshisa (oko kukuthi i-Angle yokuqhuba) ngokwesignali yesiphako sezinyo elincinci.3) Imoto yeToyota. I-TCCS magnetic induction crankshaft kunye ne-camshaft position sensoriToyota Inkqubo yoLawulo lweKhompyutha (1FCCS) isebenzisa i-crankshaft yokungenisa imagnethi kunye ne-camshaft position sensor eguqulwe kwi-distributor, equka iindawo eziphezulu kunye nezisezantsi. Inxalenye ephezulu yahlulwe kwisignali yereferensi yendawo ye-crankshaft (oku kukuthi i-cylinder identification kunye ne-TDC signal, eyaziwa ngokuba yi-G signal) generator; Inxalenye engezantsi ihlulwe kwisantya se-crankshaft kunye nomqondiso wekona (ebizwa ngokuba yi-signal ye-Ne) i-generator.1) Iimpawu zesakhiwo se-Ne generator ye-signal generator: I-generator ye-signal ye-Ne ifakwe ngaphantsi kwe-generator ye-G, ngokukodwa iqulunqwe nguNombolo we-2 ye-rotor, i-coil ye-sensor ye-Ne intloko kazibuthe.
