Yintoni i-phase sensor
Izinzwa zesigaba zizinto ezibalulekileyo ze-elektroniki zeemoto kwaye zikwasetyenziswa kwiindawo ezininzi ukulinganisa ubungakanani obubonakalayo njengendawo kunye nesantya sezinto.
Kwicandelo leemoto, isetyenziswa kakhulu ukubona ixesha levalvu yenjini ukuze kuchongwe ixesha elifanelekileyo lokutsha.
Kukho iintlobo ngeentlobo zee-phase sensors, ezahlulwe ngokweentlobo ze-magnetoelectric kunye ne-Hall, ezivelisa imiqondiso ye-sine wave kunye ne-square wave ngokulandelanayo. Ngokubanzi, ikwabandakanya ii-photoelectric sensors kunye nee-magnetic sensors.
I-photoelectric phase sensor ikhupha imiqondiso yamanqanaba ahlukeneyo ngokujikeleza iphaneli yesignali kunye nokuvula okanye ukucima i-phototransistor ngokusekelwe kuthumelo okanye ukuvala ukukhanya.
Uhlobo lweHall kwiisensa zesigaba semagnethi lusebenzisa isiphumo seHall, ngelixa uhlobo lwemagnetoelectric lusebenzisa umgaqo wokungeniswa kwemagnethi. Xa i-rotor yesignali ijikeleza, utshintsho kwisekethe yemagnethi lubangela ukuba kuveliswe amandla e-electromotive alternating kwi-induction coil.
Umgaqo wayo osebenzayo kukufezekisa umsebenzi ngokufumanisa indawo kunye nokujikeleza kwe-engile ye-camshaft. Ikhoyili yokufumanisa yangaphakathi inokuziva izinto zesinyithi ezikufutshane. Xa kungekho zinto zesinyithi, isekethe ye-LC iyavakala kwaye i-voltage ephumayo ifikelela phezulu. Xa into yesinyithi isondela, i-eddy currents ibangelwa kwikhoyili yokufumanisa, i-inductance yekhoyili iyatshintsha, isekethe ye-LC parallel iyayeka ukuvumelana, kwaye i-voltage ephumayo iyehla. Utshintsho luhambelana ngokuphambeneyo nomgama wento yesinyithi. Utshintsho lwesigaba lufunyanwa ngokulinganisa utshintsho lwe-voltage ephumayo.
Ixesha levalvu libhekisa kwi-Angle apho iivalvu zokungenisa kunye nezokukhupha injini zivulwa kwaye zivalwe khona xa kuthelekiswa nokujikeleza kwe-crankshaft. Ixesha elifanelekileyo levalvu libalulekile ekusebenzeni kwenjini, okuchaphazela amandla, ukonga amafutha kunye nokukhutshwa kwee-exhaust.
I-phase sensor inoxanduva lokujonga ukuchaneka kwe-valve train phase. Xa kukho into engaqhelekanga, i-alamu iya kuvulwa kwaye isibane se-injini siya kukhanyisa.
Izinzwa zesigaba, ezikwaligama eliqhelekileyo lezinzwa zesikhundla se-camshaft kunye nezinzwa zesikhundla se-crankshaft, zisisiseko esibalulekileyo sokumisela ixesha lokutsha kwenjini.
I-sensor yesigaba se-camshaft ibona indawo yokujikeleza kwe-camshaft kwaye ifaka isignali kwi-ECU, eyisignali ephambili yokulawula ukutsha.
I-sensor yendawo ye-crankshaft ibona i-engile ye-crankshaft yenjini kunye ne-edge ephezulu ye-piston, kwaye ithumela imiqondiso kwikhompyutha yenjini ukulawula ixesha lokutsha kunye nexesha lokufaka ipetroli. Ikwangumthombo wesignali wokulinganisa isantya senjini.
Kwezinye iinkalo, izinzwa zesigaba, ezisekelwe kumgaqo wokulinganisa isigaba, zikhupha imiqondiso kwizinto kwaye zibale ulwazi lwendawo yezinto ngokulinganisa umahluko wesigaba phakathi kwemiqondiso ekhutshiweyo nebonakalisiweyo.
Isetyenziswa kakhulu kwiindawo ezifana nokuziqhelanisa kwemizi-mveliso, i-aerospace, unyango, kunye ne-robotics, kwaye inokunceda ekulawuleni iirobhothi ngokuzimeleyo, ulawulo lokuhamba kwezithuthi zothutho, kunye nokuxilongwa kwezonyango, njl.
I-phase sensor yinxalenye ephambili yeenkqubo zolawulo lweenjini zeemoto zanamhlanje, ezenziwe zii-crankshaft position sensors kunye nee-camshaft position sensors. I-crankshaft position sensor inoxanduva lokuqokelela isantya senjini kunye nee-crankshaft Angle signals, inika ireferensi yexesha lokutsha kunye ne-fuel injection. I-camshaft position sensor iqinisekisa ukuphunyezwa ngokuchanekileyo kolawulo lwe-fuel injection olulandelelanayo kunye nolawulo lwe-detonation ngokuchonga indawo ye-dead center ephezulu ye-cylinder compression [3] [8]. Ezi zimbini zisebenza ngokubambisana ngokusebenzisa ulungelelwaniso lwesigaba, olubaluleke kakhulu ngexesha lokuqalisa kwaye lufuna ukuhambelana ngokuchanekileyo kwexesha lokuqala lokutsha [6]. Eli qela le-sensor libizwa ngokuba yi-"phase sensor" ngenxa yomsebenzi walo wolawulo olupheleleyo kwi-valve train phase kunye nexesha lokutsha.
Ukungaphumeleli kwesensor yesigaba kunokukhokelela kuthotho lweengxaki.
Ingxaki yokuqala bubunzima bokuqalisa injini. I-phase sensor kufuneka inike i-ECU ulwazi lwendawo ye-crankshaft, kwaye i-ECU ibala ixesha lokutsha kunye nomthamo wokutsalwa kwepetroli ngokusekelwe kolu lwazi. Ukuba i-phase sensor ayisebenzi kakuhle, ayinakubonelela ngolwazi oluchanekileyo. I-ECU ayinakulawula ngokuchanekileyo ukutshalwa kunye nokutsalwa kwepetroli, nto leyo eyenza injini iqale nzima okanye ingenzeki kwaphela.
Emva koko kukho ukungahlaliseki okungazinzi. Kwiimeko eziqhelekileyo, i-phase sensor ijonga indawo ye-crankshaft, ivumela iyunithi yolawulo lwenjini ukuba ilungise ixesha lokutsha kunye nomthamo wokungenisa ukuqinisekisa isantya esithambileyo sokungahlaliseki kwenjini. Nje ukuba i-phase sensor ingasebenzi kakuhle, ulwazi oludluliselwe kwi-ECU aluyi kuchaneka, kwaye ulawulo lwe-ECU kwinjini luya kuphambuka. Ngenxa yoko, isantya sokungahlaliseki siya kuba singazinzi, kwaye iingxaki ezifana nokungazinzi kokungahlaliseki kunye nesantya esitshintshatshintshayo zinokuvela.
Iya kubangela nokukhawulezisa okungekho semgangathweni. Xa imoto ikhawuleza, isenzi sesigaba kufuneka sinike ulwazi oluchanekileyo noluchanekileyo ngexesha langempela njengendawo ye-crankshaft, ukuze i-ECU ikwazi ukulungisa ngokukhawuleza amaqhinga okutsha kunye nokufaka ipetroli ukuze ihlangabezane neemfuno zokukhawulezisa imoto. Xa kwenzeka ukungasebenzi kakuhle, ulwazi aluchanekanga, i-ECU ayinakwenza uhlengahlengiso oluchanekileyo, amandla enjini ayachaphazeleka, ukukhawulezisa kuya kuba buthathaka, kwaye nokuziva ngathi unomsindo kunokwenzeka, nto leyo echaphazela amava okuqhuba.
Ukongeza, isibane sempazamo siya kukhanya. Xa inkqubo yokuxilonga iimpazamo zemoto ibona ukusilela kwesenzi sexesha, iya kuqalisa ikhowudi yempazamo, kwaye isibane sempazamo senjini kwideshibhodi siya kukhanya, okukhumbuza umnini wemoto ukuba kukho ingxaki ngesithuthi.
Okokugqibela, ukusetyenziswa kwepetroli kuyanda. Ukungasebenzi kakuhle kwe-phase sensor kubangela ukuba i-ECU ingakwazi ukulawula ngokuchanekileyo umthamo we-fuel injection. Umthamo we-fuel injection unokuba mkhulu kakhulu okanye mncinci kakhulu, nto leyo ebangela ukuba i-fuel ingagqitywanga kwaye i-fuel ingaguquki ngokufanelekileyo ibe ngamandla, nto leyo enyusa ukusetyenziswa kwepetroli.
Ukuqukumbela, ukungasebenzi kakuhle kwe-phase sensor kunempembelelo enkulu kwizithuthi. Xa kuvela ezi ngxaki zingasentla, kuyimfuneko ukuyihlola ngokukhawuleza i-phase sensor, kwaye ukuba kuyimfuneko, ukuyilungisa okanye ukuyitshintsha ukuze imoto ibuyele kwimeko yayo eqhelekileyo.
