UKUHLOLA IZINGOZI ZOKUJOVA: UKUXOXA INKINGA

Ukuxazulula inkinga kungenziwa kokubili lapho injini isebenza nalapho icishiwe.Ukuxazulula inkinga uma injini isebenza

1 Funda bese uqhathanisa i-voltage nobude be-pulse

Isignali yomjovo ingaboniswa kusetshenziswa i-oscilloscope. Ngale njongo, xhuma umugqa wokulinganisa kulayini wesignali, nomunye ulayini kuphinikhodi efanelekile yaphansi. Njengoba injini isebenza, kuyenzeka ukuthi ufunde ukucisha i-voltage kanye nobude be-pulse (isikhathi sokuvula) 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 bese uhlola amasistimu wokuthatha nawokukhipha umoya wokuvuza Izingxenye

Okunye ukuhlola okubalulekile ukukala umfutho kaphethiloli, ukuze kutholakale ezinye izakhi ezingase zibe nephutha (ipompo likaphethiloli, isihlungi sikaphethiloli, isilawuli sokucindezela), nokuhlola amasistimu okuthatha nawokukhipha umoya wokuvuza, ukuze kuvinjelwe imiphumela yokulinganisa okungamanga. 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 lapho kukhona ikhefu. Ukuhlolwa kwesekethe emfishane ukuze kuzimele kwenziwa kusetshenziswa i-ohmmeter ukusuka kuphini lokuxhuma kuya emotweni

phansi. 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.
