Into omele Uyazi malunga neSensor yokuHamba komoya

Ingcaciso

Inzwa yokuhamba komoya, eyaziwa ngokuba yimitha yokuhamba komoya, yenye yeenzwa eziphambili kwi-injini ye-EFI.Iguqula ukuhamba komoya ophefumlelweyo ube ngumqondiso wombane kwaye uyithumele kwiyunithi yokulawula i-electronic (ECU).Isivamvo esilinganisa ukuhamba komoya kwi-injini njengenye yeempawu ezisisiseko zokumisela inaliti yamafutha.

Uhlobo

Zininzi iindidi zezivamvo zokuqukuqela komoya kwiinkqubo zokutofa kwepetroli ezilawulwa ngombane.Abenzi boluvo lokuhamba komoya ngokubanzi banokuhlelwa kwi-blade (i-wing plate) uhlobo, uhlobo olungundoqo lomlinganiselo, uhlobo lwe-ray eshushu, uhlobo lwefilimu eshushu, uhlobo lomqulu we-Karman, njl njl ngokohlobo lwesakhiwo.

Indlela yokubona

Bladeuhlobo (ipleyiti ephikouhlobo) ukuhamba komoyaisivamvo

1. Ukulinganisa ixabiso lokuchasa

Okokuqala, cima i-ignition switch, qhawula intambo yamandla ebhetri, kwaye emva koko uqhawule isinxibelelanisi socingo lwephiko lohlobo lokuhamba komoya.Sebenzisa i-multimeter ukulinganisa ukuchasana phakathi kwee-terminals.Ixabiso lokumelana kufuneka lihlangabezane nexabiso eliqhelekileyo.Ngaphandle koko, inzwa yokuhamba komoya yonakele kwaye idinga ukutshintshwa.

2. Ukulinganisa ixabiso lombane

Okokuqala iplagi kwi-inlet ye-inlet ye-sensor yokuhamba komoya, emva koko ujike i-ignition switch kwi-"ON" gear kwaye usebenzise i-multimeter ukulinganisa i-voltage phakathi kwe-VC kunye ne-E2 terminals naphakathi kwe-VS kunye ne-E2 terminals.Isiphumo somlinganiselo kufuneka sihlangabezane nexabiso eliqhelekileyo.Ukuba akunjalo, inzwa yokuhamba komoya yonakele kwaye idinga ukutshintshwa.

3. Ukulinganisa umqondiso wemveliso yomsebenzi

Khupha i-harness ye-injector, qalisa injini, okanye usebenzise kuphela i-starter ukujikeleza injini kwaye usebenzise i-multimeter ukulinganisa i-voltage phakathi kwe-VS kunye ne-E2 terminals.I-voltage kufuneka iyancipha njengoko ukuvulwa kwe-blade kunyuka ngokuthe ngcembe.Ukuba akunjalo, kuthetha umoya.I-flowmeter yonakalisiwe kwaye idinga ukutshintshwa.

Uhlobo lomqulu weKarmanisivamvo sokuhamba komoya

1. Ukulinganisa ixabiso lokuchasa

Okokuqala, cima i-ignition switch, qhawula intambo yamandla ebhetri, uze uqhawule umdibaniso wocingo wemitha yokuhamba komoya.Sebenzisa i-multimeter ukulinganisa ukuchasana phakathi kwee-terminals ze-THA kunye ne-E2 zemitha yokuhamba komoya.Ixabiso elilinganisiweyo kufuneka lihambelane nexabiso eliqhelekileyo.Ukuba akunjalo, imitha yokuhamba komoya yonakele kwaye kufuneka itshintshwe.

2. Ukulinganisa ixabiso lombane

Qhagamshela i-air flow meter input connector first, emva koko ujike umtshini wokutshisa kwindawo ethi "ON" kwaye usebenzise i-multimeter ukujonga amaxabiso ombane phakathi kwee-terminals ezidweliswe kwitheyibhile.Kufuneka ihlangabezane neemfuno zexabiso eliqhelekileyo.Ngaphandle koko, imitha yokuhamba komoya yonakele kwaye kufuneka itshintshwe.

3. Ukulinganisa umqondiso wemveliso yomsebenzi

Nciphisa intambo yokubopha i-injector, qala injini okanye usebenzise isiqalisi sodwa ukuqhuba injini, kwaye usebenzise i-oscilloscope ukulinganisa ukubetha kwentliziyo phakathi kwetheminali ye-E1 kunye netheminali ye-KS.Kufuneka kubekho i-standard pulse waveform, kungenjalo i-flowmeter yomoya yonakalisiwe kwaye kufuneka itshintshwe.

Ishushufimozuluuhlobo loluvo lokuhamba komoya

1. Cima i-ignition switch, unqamule i-air flow meter input connector, kwaye usebenzise i-multimeter ukulinganisa ukuchasana phakathi kwe-3terminal kunye nendawo yokumisa umzimba wesithuthi.Kufuneka ibe ngu-0Ω.

2. Vula i-ignition switch kwi "ON" kwaye usebenzise i-multimeter ukulinganisa i-voltage phakathi kwe-terminals 2 kunye ne-3 yemitha yokuhamba komoya.Kufuneka ibe amandla ombane ebhetri.Ukuba akukho mbane okanye ukuphambuka kokufunda kukhulu kakhulu, jonga isiphaluka.Khangela ukuba i-voltage phakathi kwe-4 kunye ne-3 terminals kufuneka ibe malunga ne-5V, ngaphandle koko kuthetha ukuba kukho ingxaki ngekhebula phakathi kwe-ECU kunye ne-airflow sensor okanye i-ECU.Ukuba kukho umoya ongatshintshiyo xa unqumama, khangela ukuba amandla ombane omhlaba we-terminal #2 amalunga ne-14V, kungenjalo oko kuthetha ukuba isekethe phakathi kwemitha yokuhamba komoya kunye ne-fuel pump relay inempazamo.I-voltage phakathi kwe-#3 kunye ne-#5 ye-terminals kufuneka ibe malunga ne-1.4V xa kungekho mthwalo.Njengoko isantya se-injini sanda, i-voltage kwiziphelo zombini kufuneka iqhubeke nokunyuka, kwaye ixabiso eliphezulu li malunga ne-2.5V, ngaphandle koko imitha yokuhamba komoya kufuneka itshintshwe.

3. Cima umtshini wokutshisa kwaye ususe imitha yokuhamba komoya.Xa kungekho moya, i-voltage phakathi kwe-terminals 3 kunye ne-5 kufuneka ibe malunga ne-1.5V.Sebenzisa isivuthelo ukuvuthela umoya obandayo kwindawo yokungena yemitha yokuqukuqela komoya, uze usibuyisele umva isikhuseli ngokucothayo.Njengoko umgama ukhula, ixabiso le-voltage phakathi kwe-terminals 3 kunye ne-5 kufuneka lihle kancinci, ngaphandle koko ukuhamba komoya kufuneka kuthathelwe indawo ngokubala.

Ndiyathemba ukuba ulwazi olufanelekileyo esabelana ngalo malunga nenzwa yokuhamba komoya lunokunceda wonke umntu.Nawuphi na umdla, wamkelekile ukuba uqhagamshelane nomenzi wethu we-VW Air Flow Sensor.
