Menene ma'anar lambar matsala P0489?

Wannan sigar lambar watsawa ce gabaɗaya wacce ke nufin ta rufe duk samfura / samfura daga 1996 zuwa gaba. Koyaya, takamaiman matakan warware matsala na iya bambanta daga abin hawa zuwa abin hawa.

Waɗannan lambobin matsala na injin suna nuni ne ga rashin aiki a tsarin sake zagayawa da iskar gas. More musamman, bangaren lantarki. Tsarin sake zagayowar iskar iskar gas wani sashi ne mai mahimmanci na tsarin shaye-shayen abin hawa, wanda aikinsa shine hana samuwar NOx mai cutarwa (nitrogen oxides) a cikin silinda.

EGR yana sarrafawa ta kwamfutar sarrafa injin. Kwamfuta tana buɗewa ko rufe sake buɗe gas ɗin da ke shafar iskar gas dangane da nauyi, gudu da zafin jiki don kiyaye madaidaicin zafin silinda. Akwai wayoyi guda biyu zuwa solenoid na lantarki akan EGR wanda kwamfutar ke amfani da ita don kunna ta. Hakanan potentiometer yana cikin iskar gas mai ƙona gas, wanda ke nuna matsayin sandar EGR (tsarin aikin da ke buɗewa da rufe bututun).

Wannan yana kama da rage hasken fitilu a cikin gidan ku. Lokacin da ka kunna juyawa, hasken yana ƙara haske yayin da ƙarfin ƙaruwa yake ƙaruwa. Kwamfutar injinku ba ta ganin wani canji na wutar lantarki lokacin da yake ƙoƙarin buɗe ko rufe EGR, yana nuna cewa yana makale a wuri guda. Lambobi P0489 Cikakken Tsarin Kula da Sake Haɗin Gas "A" yana nufin babu canjin ƙarfin lantarki, yana nuna cewa EGR tana buɗewa ko rufewa. P0490 asali iri ɗaya ne, amma wannan yana nufin madauki yana da girma, ba ƙasa ba.

Man da ba a sarrafa shi yana haifar da NOx a matsanancin yanayin zafi na injin silinda. Tsarin EGR yana jagorantar adadin sarrafa gas ɗin da aka sarrafa zuwa yawan amfani. Manufar ita ce a cakuda cakuda mai shigowa da isasshen don kawo zafin zafin silinda a ƙasa da wanda aka kafa NOx.

Aiki na tsarin EGR yana da mahimmanci don dalilai fiye da rigakafin NOx - yana ba da mafi kyawun lokaci don ƙarin iko ba tare da ƙwanƙwasa ba, da kuma cakuda mai mai laushi don ingantaccen tattalin arzikin mai.
