Okuthile Okufanele Ukwazi Ngenzwa Yokugeleza Komoya

Incazelo

Inzwa yokugeleza komoya, eyaziwa nangokuthi imitha yokugeleza komoya, ingenye yezinzwa ezibalulekile enjinini ye-EFI.Iguqula ukugeleza komoya ohogelwayo ube isignali kagesi futhi iyithumele kuyunithi yokulawula ye-elekthronikhi (ECU).Inzwa ekala ukugeleza komoya enjinini njengenye yezimpawu eziyisisekelo zokunquma umjovo kaphethiloli.

Thayipha

Kunezinhlobo eziningi zezinzwa zokugeleza komoya zamasistimu omjovo kaphethiloli olawulwa ngekhompyutha.Izinzwa ezijwayelekile zokugeleza komoya zingahlukaniswa zibe uhlobo lwe-blade (wing plate), uhlobo lomgogodla wokulinganisa, uhlobo lwe-hot ray, uhlobo lwefilimu eshisayo, uhlobo lokuskrola kwe-Karman, njll. ngokuya ngohlobo lwesakhiwo.

Indlela yokuthola

Bladeuhlobo (i-wing platetype) ukugeleza komoyainzwa

1. Linganisa inani lokumelana

Okokuqala, cisha inkinobho yokuthungela, unqamule intambo yamandla yebhethri, bese unqamula isixhumi socingo senzwa yohlobo lwephiko lokugeleza komoya.Sebenzisa i-multimeter ukukala ukumelana phakathi kwamatheminali.Inani lokumelana kufanele lihlangabezane nevelu evamile.Uma kungenjalo, inzwa yokugeleza komoya ilimele futhi idinga ukushintshwa.

2. Linganisa inani le-voltage

Okokuqala xhuma isixhumi se-inlet senzwa yokugeleza komoya, bese uvula iswishi yokubasa egiyeni elithi “ON” bese usebenzisa i-multimeter ukuze ulinganise i-voltage phakathi kwamatheminali e-VC ne-E2 naphakathi kwamatheminali e-VS ne-E2.Umphumela wokulinganisa kufanele uhlangabezane nevelu evamile.Uma kungenjalo, inzwa yokugeleza komoya ilimele futhi idinga ukushintshwa.

3. Ukulinganisa isignali yokuphuma komsebenzi

Khipha ihhanisi lomjovo, qala injini, noma sebenzisa isiqalisi kuphela ukuzungezisa injini futhi usebenzise i-multimeter ukukala i-voltage phakathi kwamatheminali e-VS kanye ne-E2.I-voltage kufanele yehle njengoba ukuvulwa kwe-blade kukhula kancane kancane.Uma kungenjalo, kusho umoya.I-flowmeter yonakalisiwe futhi idinga ukushintshwa.

Uhlobo lokuskrola lwe-Karmaninzwa yokugeleza komoya

1. Linganisa inani lokumelana

Okokuqala, cisha inkinobho yokuthungela, unqamule intambo yamandla yebhethri, bese unqamula isixhumi socingo semitha yokugeleza komoya.Sebenzisa i-multimeter ukukala ukumelana phakathi kwamatheminali e-THA ne-E2 emitha yokugeleza komoya.Inani elilinganiselwe kufanele lihambisane nenani elijwayelekile.Uma kungenjalo, imitha yokugeleza komoya yonakele futhi idinga ukushintshwa.

2. Linganisa inani le-voltage

Xhuma isixhumi sokufaka imitha yokugeleza komoya kuqala, bese uvula iswishi yokuthungela endaweni ethi “VULIWE” bese usebenzisa i-multimeter ukuze uhlole amanani kagesi phakathi kwamatheminali asohlwini lwethebula.Kufanele ihlangabezane nezidingo zevelu ezijwayelekile.Uma kungenjalo, imitha yokugeleza komoya yonakele futhi kufanele ishintshwe.

3. Ukulinganisa isignali yokuphuma komsebenzi

Nqamula ihhanisi lomjovo, qala injini noma sebenzisa isiqalisi sodwa ukuze usebenzise injini, futhi usebenzise i-oscilloscope ukuze ulinganise ukushaya kwenhliziyo phakathi kwetheminali E1 kanye netheminali ye-KS.Kufanele kube ne-standard pulse waveform, ngaphandle kwalokho i-flowmeter yomoya yonakalisiwe futhi kufanele ishintshwe.

Kuyashisafisimo sezuluthayipha inzwa yokugeleza komoya

1. Vala iswishi yokuthungela, unqamule isixhumi sokufaka imitha yokugeleza komoya, bese usebenzisa i-multimeter ukuze ulinganise ukumelana phakathi kwe-3terminal kanye nendawo yaphansi yomzimba wemoto.Kufanele kube ngu-0Ω.

2. Vula inkinobho yokushisa ibe "VULIWE" futhi usebenzise i-multimeter ukukala i-voltage phakathi kwamatheminali 2 no-3 wemitha yokugeleza komoya.Kufanele kube i-voltage yebhethri.Uma ingekho i-voltage noma ukuchezuka kokufunda kukhulu kakhulu, hlola umjikelezo.Hlola ukuthi ingabe i-voltage phakathi kwamatheminali angu-4 no-3 kufanele ibe eduze kuka-5V, ngaphandle kwalokho kusho ukuthi kunenkinga ngekhebula phakathi kwe-ECU nenzwa yokugeleza komoya noma i-ECU.Uma kunomoya ongashintshi lapho ume, hlola ukuthi i-voltage yaphansi yetheminali #2 icishe ibe ngu-14V, ngaphandle kwalokho kusho ukuthi isiyingi esiphakathi kwemitha yokugeleza komoya kanye nesidluliseli sephampu yamafutha sinephutha.I-voltage ephakathi kwamatheminali angu-#3 kanye ne-#5 kufanele ibe ngu-1.4V uma ungekho umthwalo.Njengoba ijubane lenjini landa, i-voltage emikhawulweni yomibili kufanele iqhubeke ikhuphuka, futhi inani eliphakeme lingaba ngu-2.5V, ngaphandle kwalokho imitha yokugeleza komoya kufanele ishintshwe.

3. Vala inkinobho yokuthungela bese ukhipha imitha yokugeleza komoya.Uma umoya ungekho, i-voltage phakathi kwamatheminali 3 no-5 kufanele ibe ngu-1.5V.Sebenzisa isiphephetha-moya ukuvuthela umoya obandayo endaweni yokungena yemitha yokugeleza komoya, bese uyisa isiphephetha emuva kancane.Njengoba ibanga likhula, inani le-voltage phakathi kwamatheminali 3 no-5 kufanele lehle kancane kancane, ngaphandle kwalokho ukugeleza komoya kufanele kushintshwe ngokubala.

Ngethemba ukuthi ulwazi olufanele esabelane ngalo mayelana nenzwa yokugeleza komoya lungasiza wonke umuntu.Noma yiziphi izintshisekelo, wamukelekile ukuthintana nomkhiqizi wethu we-VW Air Flow Sensor.
