I-Diesel Injector Fuel Injector 5396273 Denso Injector ye-Cummins, Front Axle

1. Amaphutha avamile ama-injection enjini alawulwa nge-elekthronikhi
Ukwehluleka komjovo wenjini olawulwa nge-elekthronikhi akubangeli nje kuphela ukuthi ukuqina namandla enjini kwehle, kodwa futhi kunomthelela ekusebenzeni okujwayelekile kwenjini yemoto, okuholela ekwehleni kokuqina kwamandla enjini. Amaphutha ajwayelekile yilawa: ukuconsa, umjovo ongalungile wamafutha, umjovo kaphethiloli ongajwayelekile, njll. Ngokuvamile, kubangelwa ukunamathela kwevalvu yenaliti, ukuvaleka kahle, ukuvaleka kwesisefo, ukushiswa kwamakhoyili kanye nesignali yokulawula okungavamile. Inani likaphethiloli elijovwe umjovo kanye nokufana kokunikezwa kukaphethiloli kusilinda ngasinye nakho kuzodala ukuconsa noma ukumisa umjovo kaphethiloli.
Okwesibili, ukutholwa kwama-injection enjini alawulwa nge-elekthronikhi
1. Ukulinganisa ukumelana kwekhoyili kagesi womjovo kaphethiloli kungatholwa emotweni, noma kungalinganiswa ngemva kokukhishwa. Indlela yokulinganisa nezinga yilezi: khipha ipulaki yehhanisi lokujova uphethiloli, linganisa ukumelana phakathi kwamatheminali amabili e-injector kaphethiloli nge-multimeter, inhlangano evamile imayelana ne-12 ~ 162 (uhlobo lwe-impedance ephezulu) noma 3 ~ 62 (uhlobo oluphansi lwe-impedance ).
2. Hlola i-voltage yokuphakelwa kwamandla kagesi womjovo kagesi. I-voltage yokunikezwa kwamandla kagesi injector ingahlolwa nge-pointer noma i-multimeter yedijithali. Lapho uhlola, qala ngokukhipha amatheminali amabili omjovo kaphethiloli ngamunye ngokulandelana kwawo, bese uvula iswishi yokubasa. Uma injini ingasakwazi ukuqala ngokujwayelekile, khona-ke i-voltage kuphela ingatholwa. Izinga kufanele libe ngaphezu kwe-12V (i-voltage yokuhlinzeka amandla emoto), futhi izinga eliphansi kufanele libe ngu-0V. Uma isekethe yamandla inqanyuliwe futhi amazinga aphezulu naphansi phakathi kwamatheminali amabili epulaki yehhanisi nenjini akuziro zombili, khona-ke ifuse yomjovo kaphethiloli kanye nephampu yesibaseli kufanele ihlolwe ngokwehlukana.
