Umgangatho oPhakamileyo kaloliwe oqhelekileyo weDizili / uMbhobho we-Fuel Injector DLLA150SM018

(1) Funda uze uthelekise amandla ombane kunye nobude bexesha lokubetha kwentliziyo
Umqondiso wokutofa unokuboniswa kusetyenziswa i-oscilloscope. Ngenxa yale njongo, qhagamshela umgca wokulinganisa kumgca wesignali, kunye nomnye umgca kwipini efanelekileyo yomhlaba. Ngeenjini esebenzayo, kunokwenzeka ukuba ufunde umbane kunye nobude be-pulse (ixesha lokuvula) ukusuka kwipatheni yesignali. Xa uvula i-valve ye-throttle, ubude be-pulse kufuneka bunyuke ngexesha lesigaba sokukhawuleza, kunye nesantya se-injini esingaguqukiyo (malunga ne-3000 RPM) kufuneka sibuyele, okanye ngaphantsi nje, ixabiso elingasebenziyo. Iziphumo zeesilinda ezizimeleyo zinokuthelekiswa enye kwenye, kwaye oku kunokubonelela ngesalathiso seempazamo ezinokwenzeka, umz. umbane ongekho mgangathweni.

(2) Linganisa uxinzelelo lwepetroli kwaye ujonge iindlela zokungena kunye nokukhupha ukuvuza
Ezinye iimvavanyo ezibalulekileyo kukulinganisa uxinzelelo lwamafutha, ukwenzela ukuchonga amanye amacandelo anokuthi abe nephutha (impompo yamafutha, isihluzo samafutha, isilawuli soxinzelelo), kunye nokujonga iinkqubo zokuthatha kunye nokukhupha ukuvuza, ukukhusela iziphumo zokulinganisa ubuxoki. Ukuba i-sensor ine-2-pin isinxibelelanisi, inokwenzeka ukuba ibe yinzwa yokwazisa. Kule meko, ukuchasana kwangaphakathi, isiphaluka esifutshane esinokubakho kwisakhelo, kunye nomqondiso unokumiselwa.

Ukwenza oku, susa uxhumano lweplagi kwaye ukhangele ukuchasana kwangaphakathi kwenzwa. Ukuba ixabiso lokuchasana langaphakathi li-200 ukuya kwi-1,000 ohms (kuxhomekeke kwixabiso lokubhekisela), inzwa ilungile. Ukuba ixabiso li-0 ohms, kukho isiphaluka esifutshane, kwaye kwimeko ye-M Ohm kukho ikhefu. Uvavanyo lwesiphaluka esifutshane kwisakhelo luqhutyelwa ngokusebenzisa i-ohmmeter ukusuka kwikhonkwane yokudibanisa ukuya kumhlaba wesithuthi. Ixabiso lokuchasa kufuneka lithambekele kokungapheliyo. Uvavanyo olusebenzisa i-oscilloscope kufuneka lubangele umqondiso we-sinus wamandla aneleyo. Kwimeko yejenereyitha yeHolo, kuphela i-voltage yesignali ngendlela ye-square wave signal kunye ne-voltage yokubonelela kufuneka ivavanywe. Oku kufuneka kubangele umqondiso we-square wave ngokuxhomekeke kwisantya senjini. Kufuneka siphinde kule ndawo ukuba ukusetyenziswa kwe-ohmmeter kunokutshabalalisa i-generator yeHolo.
