Shaqada dareemaha garaaca baabuurka
Shaqada ugu weyn ee dareemaha garaaca baabuurta waa in la ogaado ifafaalaha garaaca mishiinka, iyo ka hortagga garaaca iyada oo la hagaajinayo xagasha hore ee dabka, si looga ilaaliyo mishiinka dhaawaca. ?
Dareemka garaaca ayaa u beddela gariirada makaanikada mishiinka oo u beddela calaamadaha korantada ee loo gudbiyo unugga kantaroolka elektiroonigga ah (ECU). ECU waxay hagaajinaysaa xagasha hore ee dabka iyadoo la raacayo calaamada la helay si looga fogaado in qaraxu si joogto ah u dhaco. Dareemka garaaca badanaa wuxuu isticmaalaa tignoolajiyada dhoobada piezoelectric. Marka matoorku ruxo, dhoobada waa la isku riixaa oo qaabaysana si ay u soo saarto calaamad koronto, kaas oo lagu kala qaado ECU iyada oo loo marayo siligga gaashaanka ah si loo farsameeyo.
Mabda'a shaqada ee dareenka garaaca wuxuu ku salaysan yahay saameynta piezoelectric, marka mishiinku garaaco, ceramics piezoelectric gudaha dareenka ayaa la tuujiyaa, taasoo dhalinaysa calaamad koronto. Calaamadahaan waxaa loo diraa ECU, kaas oo hagaajiya xagasha hore ee dabka iyadoo lagu salaynayo xogta la kaydiyay si looga hortago garaacid. Intaa waxaa dheer, dareemayaasha garaaca waxay dareemi karaan xawaaraha iyo booska matoorka, iyagoo siinaya macluumaad badan si ay u caawiyaan kor u qaadida waxqabadka engine.
Dareemka garaaca waxaa badanaa lagu rakibaa meel gaar ah oo ku taal block engine, sida inta u dhaxaysa 2 iyo 3 cylinders ee mishiinka afar-dhululubo ama inta u dhaxaysa 1 iyo 2 cylinders iyo 3 ama 4 cylinders. Meesha ay ku korto waxay hubisaa qabashada xasaasiga ah ee gariirada iyo garaaca mishiinka yar yar.
Haddii dareemaha garaaca uu ku guuldareysto, inkasta oo uusan sababi doonin in mishiinku ku guuldareysto inuu bilaabo, waxay keeni doontaa dhibaatooyin sida jitter engine, khasaaro koronto, hoos u dhaca dhaqaalaha shidaalka, iyo cilladaha nalalka. Sidaa darteed, hawlgalka saxda ah ee dareemaha garaaca ayaa muhiim u ah waxqabadka matoorka.
Dareemka garaaca baabuurta waa qalab lagu rakibay block engine, inta badan loo isticmaalo in lagu ogaado garaaca mishiinka. Waxaa jira noocyo badan oo dareemayaasha garaaca, kuwa ugu caansan oo ay ku jiraan magnetostrictive iyo piezoelectric ceramic.
Nooca iyo qaabka dareenka garaaca
Magnetostrictive : wuxuu ka kooban yahay xudunta birlabeedka, magnet joogto ah iyo gariiradda induction. Marka matoorku uu gariiro, xudunta birlabku wuu beddelaa, taas oo keenta isbeddel ku yimaadda qulqulka magnetic ee gariiradda induction, taasoo keentay in ay keento xoogga korantada.
Ceramic piezoelectric : Marka matoorku ruxo, dhoobada gudaha ku jirta waa la tuujiyaa si ay u soo saarto calaamad koronto. Sababtoo ah calaamaduhu waa daciif, fiilada isku xirka inta badan waxaa lagu duuduubay silig gaashaan leh.
Resonance piezoelectric: lagu rakibay qaybta sare ee jidhka matoorka, isticmaalka saamaynta piezoelectric si loogu beddelo gariirka farsamada calaamadaha korantada. Marka inta jeer ee garaaca garaaca uu la socdo inta jeer ee dabiiciga ah ee dareemayaasha, ifafaale resonance ayaa dhici doona, iyo korantada garaaca sare ee garaaca ayaa u soo bixi doonta ECU, iyadoo loo eegayo taas oo ECU ay hagaajin doonto waqtiga dabka si looga fogaado garaacid.
Sida dareeme garaaca u shaqeeyo
Dareemka garaaca ayaa dareema gariirada iyo dhawaaqa mishiinka oo u beddela calaamado koronto oo loo diro unugga kantaroolka matoorka (ECU). ECU waxay hagaajisaa xagasha hore ee dabka iyadoo la raacayo calaamada la helay si looga hortago dhacdada qarxinta. Mabda'a shaqo ee gaarka ah waa sida soo socota:
Magnetostrictive : gariirka matoorka wuxuu keenaa in xudunta birlabku is beddesho, beddelaadda qulqulka magnetic ee gariiradda induction, taasoo keentay in ay keento xoog koronto.
dhoobada piezoelectric : marka mishiinku ruxo, dhoobada piezoelectric waa la tuujiyaa si ay u soo saarto signalka korantada, ECU waxay hagaajisaa wakhtiga dabka sida ku cad calaamadda.
Nooca resonance piezoelectric: marka garaaca garaaca garaaca uu la socdo inta jeer ee dabiiciga ah ee dareemayaasha, ifafaale resonance ayaa dhacaya, iyo danab garaaca sare ee garaaca ayaa u soo baxa ECU.
Doorka dareemayaasha garaaca ee baabuurta
Shaqada ugu weyn ee dareemaha garaaca waa in la cabbiro heerka jitter ee matoorka. Marka matoorku soo saaro garaac, signalka korantada waxaa loo gudbiyaa ECU, ECU-dana waxay hagaajinaysaa xagasha hore ee dabka si ay uga hortagto garaacid kale. Garaacdu waxay sababi kartaa dhaawaca injiinka, markaa dareemayaasha garaacu waxay door muhiim ah ka ciyaaraan ilaalinta matoorka.
