Game da crankshaft firikwensin VAZ 2107

Ayyukan injin allura kai tsaye ya dogara da irin wannan sashi kamar firikwensin crankshaft. Yana aiki don tabbatar da aiki tare da injectors tare da tsarin kunnawa, saboda haka sauran sunansa shine firikwensin gaba. A VAZ 2107, injector crankshaft firikwensin na iya kasawa a kan lokaci.

Crankshaft firikwensin a kan VAZ 2107 - zane da ka'idar aiki

crankshaft matsayi firikwensin ko DPKV a kan VAZ 2107 tabbatar da aiki na engine (ba barga, amma a general). Tare da shi, ECU ya san matsayin crankshaft a ciki. Daga nan, sashin kulawa ya san wurin da pistons a cikin silinda, wanda kai tsaye ya shafi allurar man fetur ta hanyar nozzles da kuma abin da ya faru na tartsatsi don kunna tarurruka na man fetur.

Na'urar da aka yi la'akari tana da tsari mai sauƙi. Na'urori masu auna firikwensin da aka sanya a cikin duka bakwai suna aiki akan ka'idar inductance. Bangaren ya ƙunshi tushe na ƙarfe na silindical, akan saman wanda waya (coil) ya ji rauni. An rufe saman nada da maganadisu na dindindin. Aikin na'urar yana hade da kayan aiki na zobe, wanda aka haɗa zuwa crankshaft. Tare da taimakon wannan kayan aikin zobe ne na'urar ke ɗaukar siginar ta tura su zuwa kwamfutar. Ka'idar aiki na na'urar ita ce kamar haka: lokacin da haƙorin kambi ya kasance a matakin ƙarfe na DPKV, ana haifar da ƙarfin lantarki a cikin iska. Wutar lantarki yana bayyana a ƙarshen iska, wanda ECU ta saita.

Hakora na da hakora 58. An cire hakora biyu daga cikin dabaran, wanda ake buƙata don ƙayyade matsayi na farko na crankshaft. Idan DPKV kasa, wanda shi ne musamman rare, sa'an nan fara da engine da gudu shi ne kawai ba zai yiwu ba. Alamar firikwensin, wanda aka shigar akan VAZ 2107, yana da nau'i mai zuwa: 2112-3847010-03/04.

Alamomin tsinkewar firikwensin

Babban alamar lalacewar DPKV shine rashin iya kunna injin. Irin wannan gazawar yana faruwa ne saboda cikakkiyar rashin aiki na na'urar. Idan saman DPKV ya gurɓace ko lambobin sadarwa sun zama oxidized, za a iya gano abubuwan rashin aiki masu zuwa:

1. Lalacewar motsin abin hawa: rashin ƙarfi hanzari, asarar wutar lantarki, jinkirin motsi lokacin motsi.
2. Juyawa sun fara iyo, kuma ba kawai a rago ba, har ma yayin tuki.
3. Ƙara yawan man fetur. Idan ECU ta karɓi siginar da ba ta dace ba, wannan yana yin mummunan tasiri ga aikin masu injectors.
4. Bayyanar ƙwanƙwasa a cikin injin.

Idan an gano alamun da ke sama, to ya kamata a duba DPKV. Don yin wannan, kuna buƙatar sanin inda firikwensin crankshaft yake. A kan Vaz 2107 DPKV yana a gaban murfin injin, inda aka ɗora shi akan wani sashi. A wasu nau'ikan mota, wannan sinadari na iya kasancewa a gefe guda na crankshaft kusa da ƙangin tashi. Idan kuna zargin rashin aiki na DPKV, ya kamata ku duba shi.

Hanyoyin duba DPKV

Kuna iya bincika isasshiyar firikwensin crankshaft akan duka bakwai ta hanyoyi daban-daban guda uku. Da farko, ya kamata a lura nan da nan cewa ana iya tantance rashin aikin na'urar ta gani. Don yin wannan, duba sashin, kuma a gaban kamuwa da cuta, da kuma microcracks a cikin gidan magnet, wanda zai iya yin hukunci da gazawarsa. Ana cire gurɓataccen gurɓataccen abu cikin sauƙi, amma a gaban microcracks, dole ne a canza sashin.

Ana duba firikwensin crankshaft akan injector VAZ 2107 ta hanyoyi uku:

1. Duban juriya. An saita multimeter zuwa yanayin auna juriya. Binciken ya taɓa tasha na na'urar. Idan na'urar ta nuna darajar daga 550 zuwa 750 ohms, to kashi ya dace don amfani. Idan darajar ta fi girma ko ƙasa da na al'ada, to dole ne a maye gurbin sashin.
2. Duba inductance. Haɗa LED ko multimeter kaiwa zuwa tashoshi na na'urar. A lokaci guda, saita na'urar zuwa yanayin auna wutar lantarki na DC. Kawo wani abu na ƙarfe zuwa ƙarshen yanki kuma cire shi da sauri. A wannan yanayin, haɓaka ƙarfin lantarki ya kamata ya faru (LED zai haskaka). Wannan yana nuna cewa DPKV yana aiki.
3. Binciken Oscilloscope. Hanya mafi inganci kuma abin dogaro don gwadawa tare da oscilloscope. Don yin wannan, an haɗa DPKV zuwa na'urar, sa'an nan kuma dole ne a kawo sashin ƙarfe zuwa gare ta. Da'irar tana ƙayyade daidaitaccen aiki na DPKV.

Na'urar firikwensin crankshaft ɗin da aka yi amfani da shi akan bakwai ɗin yana haifar da bugun jini na sinusoidal. Suna shiga kwamfutar, inda aka gyara su zuwa ƙwanƙwasa rectangular. Dangane da waɗannan nau'ikan bugun jini, sashin kulawa ya yanke shawarar yin amfani da bugun bugun jini zuwa injectors da filogi a lokacin da ya dace. Idan yayin gwajin ya nuna cewa DPKV ba daidai ba ne, dole ne a maye gurbinsa.

Yadda za a maye gurbin firikwensin crankshaft akan bakwai

Sanin inda DPKV yake a kan VAZ 2107, ba zai zama da wuya a kwance na'urar ba. Wannan hanya ba ta da wahala kuma baya ɗaukar lokaci mai yawa. Cikakken umarnin kan yadda za a maye gurbin firikwensin crankshaft akan Vaz 2107 yayi kama da wannan:

1. Ana aiwatar da aikin a ƙarƙashin murfin motar, amma kuma ana iya yin hakan daga ƙasa.
2. Cire haɗin kebul ɗin daga DPKV.
3. Yin amfani da screwdriver Phillips, cire faifan shirin da ke tabbatar da firikwensin.
4. Cire na'urar kuma shigar da sabo a wurinsa. Ana gudanar da taro a cikin juzu'i na wargajewa.

Bayan maye gurbin na'urar, zaku iya duba aikin injin. Kodayake ɓangaren ba kasafai yake kasawa ba, ana ba da shawarar koyaushe a sami firikwensin firikwensin a cikin injin. Idan wani abu ya gaza, koyaushe ana iya maye gurbinsa da sauri don ci gaba da motsi.

A sakamakon haka, ya kamata a lura cewa DPKV shine mafi mahimmancin firikwensin. Yana da tsari mai sauƙi kuma da wuya ya gaza. Kimanin farashin na'urar ga duk bakwai shine kusan 1000 rubles. Ana ba da shawarar duba sashin ba kawai a alamun farko na rashin aiki ba, har ma don tsaftace aikin lokaci-lokaci daga gurɓata.
