Ikhwalithi Ephakeme I-Common Rail Diesel /Fuel Injector Nozzle DLLA150SM018

(1) Funda futhi uqhathanise amandla kagesi kanye nobude besikhathi sokushaya kwenhliziyo
Isignali yomjovo ingaboniswa kusetshenziswa i-oscilloscope.Ngale njongo, xhuma umugqa wokulinganisa kulayini wesignali, futhi omunye umugqa ube nephinikhodi efanelekile.Ngokusebenza kwenjini, kuyenzeka ukuthi ufunde i-voltage kanye nobude be-pulse (isikhathi sokuvula) kusuka kuphethini yesignali.Lapho uvula i-throttle valve, ubude be-pulse kufanele bukhuphuke phakathi nesigaba sokusheshisa, futhi ngesivinini senjini esingaguquki (cishe 3000 RPM) kufanele sibuyele emuva, noma ngezansi nje, inani lokungenzi lutho.Imiphumela yamasilinda angawodwana ingaqhathaniswa namanye, futhi lokhu kungase kunikeze inkomba yamaphutha angenzeka, isb.

(2) Linganisa umfutho kaphethiloli futhi uhlole amasistimu wokudonsa nawokukhipha umoya ukuze avuze
Okunye ukuhlola okubalulekile ukukala umfutho kaphethiloli, ukuze kutholwe ezinye izakhi ezingase zibe nephutha (ipompo likaphethiloli, isihlungi sikaphethiloli, isilawuli sokucindezela), kanye nokuhlola amasistimu okudonsa nokukhipha umoya ukuvuza, ukuvimbela imiphumela yokulinganisa engamanga.Uma inzwa inesixhumi samaphini angu-2, kungenzeka kakhulu ukuthi kube inzwa eguquguqukayo.Kulesi simo, ukumelana kwangaphakathi, isifunda esifushane esingase sibe nohlaka, kanye nesignali inganqunywa.

Ukuze wenze lokhu, susa uxhumano lwepulaki bese uhlola ukumelana kwangaphakathi kwenzwa.Uma inani lokumelana kwangaphakathi lingu-200 kuya ku-1,000 ohms (kuye ngokuthi inani lereferensi), inzwa ILUNGILE.Uma inani lingu-0 ohms, kukhona isifunda esifushane, futhi esimweni se-M Ohm kukhona ikhefu.Ukuhlolwa kwesekethe emfishane yokufaka ifreyimu kwenziwa kusetshenziswa i-ohmmeter ukusuka kuphini lokuxhuma kuya endaweni yemoto.Inani lokumelana kufanele lithambekele kokungapheli.Ukuhlolwa kusetshenziswa i-oscilloscope kufanele kuphumele esignali ye-sinus yamandla anele.Endabeni yejeneretha yeHholo, i-voltage yesiginali kuphela esesimweni sesignali ye-square wave kanye ne-voltage yokunikezela okufanele ihlolwe.Lokhu kufanele kuphumele esignali yegagasi eliyisikwele kuye ngesivinini senjini.Kufanele siphinde kuleli phuzu ukuthi ukusetshenziswa kwe-ohmmeter kungabhubhisa i-generator yeHholo.
