Indlela Yokuhlola Inzwa Yehholo Nge-Multimeter (Umhlahlandlela)

Ukuphelelwa amandla, umsindo omkhulu, nomuzwa wokuthi injini ikhiyiwe ngandlela thize kuyizimpawu zokuthi ubhekene nesilawuli esifile noma izinzwa ze-hall effect crank ngaphakathi kwenjini yakho. 

Landela lezi zinyathelo ukuze uhlole inzwa yomphumela weHholo nge-multimeter.

Okokuqala, setha i-DMM ku-DC voltage (20 volts). Xhuma umkhondo omnyama we-multimeter kumthofu omnyama wenzwa yehholo. Itheminali ebomvu kufanele ixhunywe kuntambo ebomvu ephozithivu yeqembu lezintambo zenzwa yaseHholo. Kufanele uthole ukufundwa kwamavolthi ayi-13 ku-DMM. Qhubeka uhlole ukuphuma kwezinye izintambo.

Inzwa yeHholo iyi-transducer ekhiqiza i-voltage ephumayo ngokuphendula inkambu kazibuthe. Kulesi sihloko, uzofunda ukuthi ungayihlola kanjani inzwa yeHholo nge-multimeter.    

Kwenzekani lapho izinzwa zeHholo zihluleka?

Ukwehluleka kwezinzwa zeHholo kusho ukuthi isilawuli (ibhodi elinika amandla futhi elilawula injini) asinalo ulwazi olubalulekile oludingekayo ukuze sivumelanise kahle amandla emoto. Injini inikwa amandla yizintambo ezintathu (izigaba). Izigaba ezintathu zidinga isikhathi esifanele noma injini izobambeka, iphelelwe amandla futhi yenze umsindo ocasulayo.

Ingabe usola ukuthi izinzwa zeHholo lakho zinephutha? Ungahlola nge-multimeter ngokulandela lezi zinyathelo ezintathu.

1. Nqamula futhi uhlanze inzwa

Isinyathelo sokuqala sihlanganisa ukususa inzwa ku-cylinder block. Qaphela ukungcola, izinsimbi zensimbi namafutha. Uma kukhona okunye kwalokhu, kususe.

2. Indawo yenzwa ye-Camshaft/crankshaft

Hlola isikimu senjini ukuze uthole inzwa ye-camshaft noma inzwa yendawo ye-crankshaft kumojula yokulawula kagesi (ECM) noma inzwa ye-camshaft. Bese uthinta umkhawulo owodwa wentambo ye-jumper ocingweni lwesignali kanye nolunye uhlangothi ekugcineni kwe-probe ephozithivu. I-probe enegethivu kufanele ithinte indawo ekahle ye-chassis. Cabangela ukusebenzisa i-crocodile clip jumper lapho uxhuma i-negative test ku-chassis ground - uma kudingeka.

3. I-voltage yokufunda ku-multimeter yedijithali

Bese usetha i-multimeter yedijithali ku-DC voltage (20 volts). Xhuma umkhondo omnyama we-multimeter kumthofu omnyama wenzwa yehholo. Itheminali ebomvu kufanele ixhunywe kuntambo ebomvu ephozithivu yeqembu lezintambo zenzwa yaseHholo. Kufanele uthole ukufundwa kwamavolthi ayi-13 ku-DMM.

Qhubeka uhlole ukuphuma kwezinye izintambo.

Bese uxhuma ucingo olumnyama lwe-multimeter ocingweni olumnyama lwehhanisi lezintambo. Intambo ebomvu ye-multimeter kufanele ithinte ucingo oluluhlaza kumahhanisi ocingo. Hlola ukuthi i-voltage ikhombisa ama-volts amahlanu noma ngaphezulu. Qaphela ukuthi i-voltage incike ekufakweni kwesekethe futhi ingahluka kusuka kudivayisi eyodwa kuya kwenye. Nokho, kufanele ibe nkulu kunoziro volts uma izinzwa zeHholo ZILUNGILE.

Hambisa kancane uzibuthe kuma-engeli angakwesokudla uye ngaphambili kwesishumeki. Bheka ukuthi kwenzakalani. Njengoba usondela eduze kwenzwa, i-voltage kufanele inyuke. Njengoba uhamba, i-voltage kufanele yehle. Inzwa yakho ye-crankshaft noma ukuxhumana kwayo kunephutha uma lungekho ushintsho ku-voltage.

Ukufingqa

Izinzwa zehholo zinikeza izinzuzo eziningi njengokwethembeka okudingeka kakhulu, ukusebenza kwesivinini esikhulu, kanye nokuphumayo nama-engeli kagesi ahlelwe ngaphambilini. Abasebenzisi futhi bayayithanda ngenxa yekhono layo lokusebenza kumazinga okushisa ahlukahlukene. Zisetshenziswa kakhulu ezimotweni eziphathwayo, imishini ezishintshayo, izinto zokuphatha zasolwandle, imishini yezolimo, imishini yokusika nokuhlehlisa, kanye nemishini yokucubungula nokupakisha.
