Mene ne wannan yake nufi?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi duk motocin 1996 (Nissan, Honda, Infiniti, Ford, Dodge, Acura, Toyota, da sauransu). Kodayake gabaɗaya a yanayi, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.

Na sani daga gogewa cewa lambar da aka adana P2012 tana nufin cewa module powertrain control module (PCM) ya gano madaidaicin madaidaicin iko (IMRC) wutar lantarki (don bankin injin 2) wanda ya yi ƙasa da yadda ake tsammani. Banki na 2 yana nuna mani rashin aiki wanda ke da alaƙa da ƙungiyar injiniya wanda ba shi da silinda na ɗaya.

Kwamfutar PCM ce ke sarrafa tsarin IMRC. Ana amfani dashi don sarrafawa da daidaita yanayin iska zuwa ƙananan abubuwan da ake ci, kawunan silinda da ɗakunan konewa. Fuskokin ƙarfe masu siffa na musamman, waɗanda suka yi daidai da madaidaiciyar hanyar shigar kowane silinda, mai kunnawa mai kula da tafiye -tafiye na lantarki ya buɗe kuma ya rufe. Ana haɗe da ƙananan baƙin ƙarfe na baƙin ƙarfe (tare da ƙananan kusoshi ko rivets) zuwa sandar ƙarfe wanda ke shimfida tsawon kowane kan silinda kuma yana ratsa tsakiyar kowace tashar shiga. Ganyen yana buɗewa a cikin motsi guda ɗaya, wanda ke ba da damar duk ganye su zama naƙasasshe idan ɗayansu ya makale ko ya makale. Hannun injin ko kayan aiki galibi yana makantar da mai kunnawa IMRC zuwa tushe. Wasu samfura suna amfani da diaphragm na injin don sarrafa mai kunnawa. PCM tana sarrafa lantarki na lantarki wanda ke sarrafa injin tsotsewa ga mai kunnawa IMRC lokacin da ake amfani da injin injin.

Bincike ya nuna cewa tasirin da ke juyawa (kwararar iska) yana inganta ƙarin cikakkiyar gurɓataccen man fetur / iska. Ƙarfafa atomization yana taimakawa rage ƙona hayaƙi, inganta haɓakar mai da haɓaka aikin injin.

Jagoranci da ƙuntata iskar iska yayin da aka jawo shi a cikin injin yana haifar da wannan tasiri mai jujjuyawa, amma masana'antun daban-daban suna amfani da hanyoyin IMRC daban-daban. Koma tushen bayanin abin hawan ku (Dukkanin Bayanan DIY babban hanya ne) don cikakkun bayanai kan tsarin IMRC wanda wannan abin hawa ke sanye da shi. Yawanci, masu gudu na IMRC suna kusa rufewa yayin farawa/rago kuma suna buɗe mafi yawan lokutan lokacin da ma'aunin yana buɗewa.

Don tabbatar da cewa tsarin IMRC yana aiki yadda yakamata, PCM yana lura da shigarwar bayanai daga firikwensin matsayi na IMRC, firikwensin matsin lamba (MAP) da yawa, firikwensin zafin iska mai yawa, yawan firikwensin zafin zafin iska, maɗaurin matsin lamba, oxygen. na'urori masu auna firikwensin da firikwensin iska (MAF) (da sauransu).

PCM yana sa ido kan ainihin matsayin murfin impeller kuma yana daidaita shi gwargwadon bayanan sarrafa injin. Fitilar mai nuna rashin aiki na iya haskakawa kuma za a adana lambar P2012 idan PCM bai ga wani canji mai mahimmanci a MAP ko yawan zafin iska kamar yadda aka zata ba. A wasu lokuta, zai ɗauki raunin gazawa da yawa don haskaka MIL.
