Ungahlola kanjani ikhoyili ye-magneto nge-multimeter

Ngezimoto zesimanje azipheli lapho izinkinga zingavela khona.

Nokho, izimoto ezindala nezinjini kungenye ingxenye okufanele ucabange ngayo; amakhoyili e-magneto.

Amakhoyili kaMagneto ayizingxenye ezibalulekile ezinhlelweni zokuthungela umlilo zezindiza ezincane, ogandaganda, abasika utshani nezinjini zezithuthuthu, phakathi kokunye.

Abantu abaningi abazi ukuthi bangabheka kanjani lezi zingxenye ukuze bathole izinkinga, futhi silapha ukuze sikusize.

Kulo mhlahlandlela uzofunda okulandelayo:

• Iyini ikhoyili ye-magneto futhi isebenza kanjani?
• Izimpawu zekhoyili ye-magneto embi
• Uyivivinya Kanjani Ikhoyili yeMagneto usebenzisa i-Multimeter
• Futhi imibuzo evame ukubuzwa

Iyini ikhoyili ye-magneto futhi isebenza kanjani?

I-magneto iyijeneretha kagesi esebenzisa uzibuthe ongunaphakade ukuze kwakhe ama-pulses ezikhathi ezithile futhi aqinile wamanje kunokuba alethe ngokuqhubekayo.

Ngamakhoyili ayo, ihlinzeka ngale shayela enamandla yamanje ku-spark plug, okhela amagesi acindezelwe ohlelweni lokulawula ukuthungela kwenjini. 

Wakheka kanjani lo mfutho?

Kunezingxenye ezinhlanu ezisebenza ndawonye ukwenza i-magneto isebenze:

• Isikhali
• Ikhoyili yokuthungela eyisisekelo eyenziwe ngamajika angu-200 ocingo oluwugqinsi
• Ikhoyili yesibili yokuthungela eyenziwe ngamajika angu-20,000 ocingo oluhle, kanye
• Iyunithi yokulawula ngogesi
• I-flywheel yenjini inozibuthe ababili abaqinile abakhelwe kuyo.

I-armature iyisici esimise okuka-U esitholakala eduze kwe-flywheel futhi lapho kulinyazwa khona amakhoyili amabili okuthungela kamagneto.

Ngokomthetho kaFaraday, noma ikuphi ukunyakaza okuhlobene phakathi kukazibuthe nocingo kubangela ukugeleza kwamanje nokugeleza ocingweni. 

I-flywheel yenjini inozibuthe ababili abakhelwe kuyo endaweni ethile. 

Uma i-flywheel iphenduka futhi leli phuzu lidlula i-armature, izinkundla kazibuthe ezivela kuzibuthe zisetshenziswa kuyo ngezikhathi ezithile.

Khumbula ukuthi amakhoyili ocingo akwi-armature, futhi ngokomthetho kaFaraday, le nkundla kazibuthe inika amakhoyili amandla kagesi.

Lapha ungabona indlela yokuhambisa ucingo.

Lokhu kunikezwa ngezikhathi ezithile kwamanje kunqwabelana kumakhoyili futhi kufinyelele ezingeni eliphezulu.

Uma lesi sibalo esiphezulu sesifinyelelwe, iyunithi yokulawula ye-elekthronikhi ivula iswishi bese kuthi abathintwayo bavuleke.

Lokhu kuqhuma okungazelelwe kuthumela umfudlana wamandla kagesi anamandla kuma-spark plug, aqalise injini. Konke lokhu kwenzeka emizuzwaneni embalwa.

Manje i-magneto ingase ingasayifezi injongo yayo ngokuphumelelayo, futhi izigebengu ngokuvamile zingamakhoyili. 

Izimpawu zekhoyili ye-magneto embi

Uma ikhoyili ye-magneto inephutha, uhlangabezana nokulandelayo:

• Ilambu lesexwayiso lenjini liyakhanya kudeshibhodi
• Ubunzima bokuqalisa injini
• Ibanga elikhulu elihanjwa ngegesi
• Ukuntuleka kwamandla okusheshisa

Uma ubona noma yikuphi kwalokhu, inkinga ingase ibe ngamakhoyili azibuthe.

Njengokuhlola ezinye izinto zikagesi kanye nezingxenye, uzodinga i-multimeter ukuhlola lawa makhoyili.

Uyivivinya Kanjani Ikhoyili yeMagneto usebenzisa i-Multimeter

Khipha ibhuthi yenjoloba, setha i-multimeter ibe yi-ohms (ohms) futhi uqiniseke ukuthi ububanzi be-ohms busethelwe ku-40k ohms ngaphandle kokwenza i-autoranging. Beka imikhondo ye-multimeter ekujikeni kwethusi kwe-magneto kanye ne-clamp yensimbi ngaphansi kwesikhwama senjoloba. Noma yikuphi ukufunda ngezansi noma ngaphezulu kobubanzi obuyi-3k kuya ku-15k kusho ukuthi ikhoyili kazibuthe yimbi.

Lena incazelo eyisisekelo neqondile kuphela yalokho okudingeka ukwenze, futhi incazelo eyengeziwe iyadingeka ukuze uqonde kahle inqubo.

1. Nqamula indlu ye-flywheel

Isinyathelo sokuqala ukunqamula i-flywheel housing kukho konke ukufakwa.

I-flywheel housing iyikesi yensimbi evala uzibuthe futhi ibanjwe amabhawudi amathathu.

Izinjini ezakhiwa ngeminyaka yawo-1970 ngokuvamile zinamabhawodi amane abambe i-casing endaweni. 

2.  Thola ikhoyili ye-magneto

Uma ikhava isisusiwe uzothola ikhoyili ye-magneto.

Ukuthola ikhoyili ye-magneto akufanele kube yinkinga ngoba iyona kuphela ingxenye engemuva kwekesi enamawindi ethusi avele obala noma ingqikithi yensimbi.

Lawa mawindi e-copper (armature) enza umumo ongu-U. 

3. Susa isikhwama senjoloba

Ikhoyili ye-magneto inezintambo ezivikelwe isikhwama senjoloba ezingena ku-spark plug. Ukuze uhlole lokhu, kufanele ususe le boot yerabha ku-spark plug.

4. Setha isikali se-multimeter

Ngekhoyili yamagneto, ulinganisa ukumelana. Lokhu kusho ukuthi ukudayela kwakho kwe-multimeter kusethwe ku-ohms, emelelwa uphawu lwe-omega (Ω).

Esikhundleni sokwenza i-autoranging, usetha ngesandla i-multimeter kububanzi obungu-40k ohm. Lokhu kungenxa yokuthi ukukhetha kwebanga okuzenzakalelayo kukhiqiza imiphumela engathembeki kakhulu.

5. Ukuma kwe-multimeter probes

Manje, ukukala ukumelana ngaphakathi kwekhoyili ye-magneto, udinga ukwenza izinto ezimbili. Ufuna ukukala amakhoyili okuqala kanye nawesibili.

Ukuze uthole ikhoyili eyinhloko, beka i-multimeter probe ebomvu ekujikeni okumise okuka-U bese uhlikihla i-probe emnyama endaweni yensimbi.

Ukuze ulinganise ukujikajika kwesibili, beka enye yama-multimeter probe kumongo wensimbi omise okwe-U (i-winding) bese ufaka enye i-probe endlini yenjoloba ngakolunye uhlangothi lwe-magneto. 

Ngenkathi le dipstick isendaweni yerabha, qiniseka ukuthi ithinta isiqeshana sensimbi esikuyo.

Nansi ividiyo ekhombisa kahle ukuthi ulinganisa kanjani amakhoyili kazibuthe ayisisekelo kanye nawesibili.

6. Linganisa imiphumela

Uma ama-probe ebekwe ezingxenyeni ezahlukene ze-magneto, uhlola ukufundwa ku-multimeter.

Ukufundwa kungama-kiloohms futhi kufanele kusuke ku-3k ohms kuye ku-15k ohms, kuye ngohlobo lwe-magneto oluhlolwayo.

Ukubonisana nebhukwana lomkhiqizi kuzokusiza kulokhu. Noma yikuphi ukufunda ngaphandle kwalolu hlu kusho ukuthi ikhoyili yakho ye-magneto inephutha.

Ngezinye izikhathi i-multimeter ingase ibonise "OL", okusho ukuthi kukhona isifunda esivulekile noma isifunda esifushane phakathi kwala maphuzu amabili. Kunoma yikuphi, ikhoyili ye-magneto idinga ukushintshwa.

Ngaphezu kwalokhu, kukhona amathiphu athile okufanele ukunakwa.

Uma i-multimeter yakho ifundeka ngaphezu kuka-15k ohms, imbangela kungase kube ukuxhumana phakathi kwentambo yamandla kagesi aphezulu (HV) kukhoyili kanye nensimbi yokuqinisa eya ku-spark plug. 

Uma konke lokhu kuhlolwa futhi i-magneto ibonisa ukufundwa kokumelana okulungile, khona-ke inkinga ingase ibe ipulaki ye-spark noma omazibuthe ababuthakathaka ku-flywheel.

Hlola lezi zingxenye ngaphambi kokuthatha isinqumo sokushintsha i-magneto.

Imibuzo evame ukubuzwa

Kufanele ibe nama-ohm amangaki ikhoyili yokuthungela?

Ikhoyili ye-magneto enhle izonikeza ukufundwa kwe-ohm kusuka ku-3 kuya ku-15k ohms kuye ngemodeli. Noma yikuphi ukufunda ngezansi noma ngaphezulu kwalobu bubanzi kubonisa ukuthi kunephutha futhi kungase kudingeke ukuthi kubushintshe.

Ungahlola kanjani i-magneto ukuthola inhlansi?

Ukuze uhlole i-magneto yenhlansi, usebenzisa isihloli senhlansi. Xhuma isiqeshana sengwenya yalesi sihloli senhlansi kukhoyili kazibuthe, zama ukuvula injini futhi ubone ukuthi lo mhloli uyayikhipha yini inhlansi.

Uyivivinya Kanjani Ikhoyili Yemoto Encane Usebenzisa I-Multimeter

Vele ubeke umkhondo we-multimeter kumongo wensimbi umumo othi "U" kanye ne-metal spark plug clamp ngakolunye uhlangothi. Ukufundwa ngaphandle kobubanzi obungu-3k ohm ukuya ku-5k ohm kusho ukuthi inephutha.

Uyihlola kanjani i-magneto capacitor

Setha imitha ku-ohms (ohms), beka i-probe ebomvu kusixhumi esishisayo, bese ugawula uphenyo olumnyama endaweni yensimbi. Uma i-capacitor inephutha, imitha ngeke inikeze ukufundwa okuzinzile.

I-magneto ikhiqiza amavolthi amangaki?

I-magneto enhle ikhiqiza cishe ama-volts angama-50. Uma ikhoyili ifakiwe, leli nani liyakhuphuka libe ngu-15,000 volts futhi lingalinganiswa kalula kusetshenziswa i-voltmeter.
