I-Diesel Injector Fuel Injector 095000-5361 Denso Injector ye-Isuzu

Eyesihlanu iwukubona amandla okufaka uphethiloli. Khipha ipulaki yocingo lomjovo kaphethiloli, vula isikhiya sokuthungela, lungisa i-multimeter ibe izinga likagesi le-DC, kala i-voltage kupulaki yocingo, xhuma ipulaki nomthofu obomvu wokuhlola we-multimeter ukuze uthinte izikhonkwane ezimbili zepulaki. ipulaki ngokulandelana, bese uxhuma omunye umthofu wokuhlola omnyama egobolondweni lenjini , futhi ama-voltage angu-12V (i-voltage yebhethri ngaleso sikhathi) kanye ne-OV ngokulandelanayo. Uma zonke ziyi-OV, kukhombisa ukuthi kunenkinga ngokuphakelwa kwamandla kagesi ojova uphethiloli, futhi ibhokisi le-fuse elihambisanayo nezinto zikagesi kufanele zihlolwe.
Okwesithupha ukuhlolwa kwesifunda sokulawula umjovo. Khipha ipulaki yentambo yesijojo sikaphethiloli, vula isikhiya sokuthungela, umthofu obomvu wokuhlola we-multimeter uxhunywe kumaphini amabili epulaki ngokulandelanayo, kanti omunye umthofu omnyama wokuhlola uxhumeke kukesi lenjini, ama-voltage angu-12V no-0V. ngokulandelana, thola iphinikhodi ye-0V bese uyiMaka, lena yisekethe yokulawula i-injector. Xhuma ipulaki yentambo yesijovi sikaphethiloli, vula isikhiya sokuthungela, futhi ulinganise i-voltage phakathi kolayini wokulawula umjovo kaphethiloli kanye nekesi lenjini, okufanele libe likhulu kuno-10.5V. Enye indlela ukuhlola ngepeni lokuhlola likagesi lemoto, elinama-diode amabili akhipha ukukhanya, ukunqamula ipulaki yentambo yokujova uphethiloli, ukuxhuma izikhonkwane ezimbili zepeni lokuhlola imoto kuzikhonkwane zepulaki, bese usebenzisa isiqalisi ukudonsa Qala injini. , bheka ama-diode, ama-LED kufanele akhanyise ngokushintshana, okubonisa ukuthi isignali yokulawula ijwayelekile.
Okwesikhombisa ukutholwa kwesignali yomjovo kaphethiloli. Gada ububanzi bokushaya komjovo kaphethiloli ngosizo lwethuluzi lokuhlola iphutha lenjini noma i-oscilloscope. Ngaphansi kwezimo ezijwayelekile, ububanzi be-pulse umjovo kaphethiloli wenjini bungu-2 ~ 10mS. Ngokuvamile, ukutholwa kuhlukaniswe izigaba ezine, esinye isigaba sokungenzi lutho; enye yisiteji sokulayisha esincane nesiphakathi; okwesithathu yisiteji somthwalo osindayo. Lezi zigaba ezintathu ziwukuhlola ukufana kwesiginali yomjovo wesilinda isilinda ngasinye. Okwesine yisigaba sokunqanyulwa kukaphethiloli se-stroke. Uma injini ivala i-throttle ngokushesha ngesivinini esikhulu, umjovo kaphethiloli kufanele umise umjovo kaphethiloli isikhathi esifushane, futhi ububanzi bepulse umjovo kaphethiloli bube ngu-0mS ngesikhathi esifushane.
