Yadda ake duba firikwensin sauri

idan ICE yana tsayawa ba aiki, to, mafi mahimmanci, kuna buƙatar bincika na'urori masu auna firikwensin (DMRV, DPDZ, IAC, DPKV) don sanin mai laifi. Tun da farko mun kalli hanyoyin tabbatarwa:

• firikwensin matsayi na crankshaft;
• firikwensin matsayi na maƙura;
• firikwensin aiki;
• firikwensin iska mai yawa.

Yanzu za a ƙara duba saurin firikwensin yi-da-kanka zuwa wannan jeri.

A yayin da aka samu raguwa, wannan firikwensin yana watsa bayanan da ba daidai ba, wanda ke haifar da rashin aiki na ba kawai injin konewa na ciki ba, har ma da sauran abubuwan da ke cikin motar. Mitar saurin abin hawa (DSA) tana aika sigina zuwa firikwensin wanda yana sarrafa aikin injin a zaman banza, da kuma, ta amfani da PPX, yana sarrafa iskar da ke ƙetare magudanar ruwa. Mafi girman saurin abin hawa, mafi girman mitar waɗannan sigina.

Ka'idar aiki na firikwensin sauri

Na'urar firikwensin saurin mafi yawan motocin zamani yana dogara ne akan tasirin Hall. A cikin aikinta, ana isar da shi zuwa kwamfutar motar tare da siginar bugun bugun jini a cikin ɗan gajeren lokaci. wato tsawon kilomita daya na hanya, firikwensin yana watsa sigina kusan 6000. A wannan yanayin, mitar watsawar motsa jiki yana daidai da saurin motsi kai tsaye. Naúrar sarrafa lantarki ta atomatik tana ƙididdige saurin abin hawa bisa mitar sigina. Yana da shirin don wannan.

Idan ba a warware matsalar ba, to yana da kyau a duba firikwensin saurin don aiki. Yanzu tambaya ta taso: yadda za a duba saurin firikwensin?

A kan motocin VAZ, da sauransu, ana shigar da firikwensin sau da yawa wanda ke aiki bisa ga tasirin Hall (yawanci yana ba da bugun jini 6 a cikin cikakken juyin juya hali). Amma akwai kuma na'urori masu auna firikwensin wata ka'ida: reed da inductive... Bari mu fara la'akari da tabbacin mafi mashahuri DSA - dangane da tasirin Hall. Na'urar firikwensin sanye take da fil uku: ƙasa, ƙarfin lantarki da siginar bugun jini.

Ana duba firikwensin sauri

Da farko kuna buƙatar gano idan akwai ƙasa da ƙarfin lantarki na 12 V a cikin lambobin sadarwa. Ana kunna waɗannan lambobin sadarwa kuma ana gwada lambar bugun bugun zuciya.

Hanyar 1 (duba tare da voltmeter)

1. Muna rushe firikwensin saurin.
2. Muna amfani da voltmeter. Mun gano wane tashar ne ke da alhakin menene. Muna haɗa lamba mai shigowa na voltmeter zuwa tashar da ke fitar da siginar bugun jini. Alamar na biyu na voltmeter tana ƙasa akan injin konewa na ciki ko jikin mota.
3. Juyawa na'urar firikwensin saurin, muna ƙayyade shin akwai wasu sigina a cikin zagayowar aiki kuma auna ƙarfin fitarwa na firikwensin. Don yin wannan, za ka iya sanya wani bututu a kan axis na firikwensin (juya a gudun 3-5 km / h.)

2. Muna haɗa lambobin firikwensin tare da voltmeter.
3. Muna juya motar kuma mu bincika ko ƙarfin lantarki ya bayyana - idan akwai ƙarfin lantarki da mita a cikin Hz, to, firikwensin gudu yana aiki.

Hanyar 3 (duba tare da sarrafawa ko kwan fitila)

1. Cire haɗin waya mai motsawa daga firikwensin.
2. Amfani da sarrafawa, muna neman "+" da "-" (a da kunna wuta).
