Ileveli yesiginali ephansi kusekethe yenzwa yokukhipha igesi ephumayo kabusha

Kusho ukuthini lokhu?

Le khodi iyikhodi yokudlulisela ejwayelekile. Kubhekwa njengendawo yonke njengoba kusebenza kukho konke ukwakheka namamodeli ezimoto (1996 nangaphezulu), yize izinyathelo ezithile zokulungisa zingahluka kancane ngokuya ngemodeli.

Kunemiklamo ehlukene yezinhlelo zokuphindaphinda igesi ephumayo, kodwa zonke zisebenza ngendlela efanayo. I-Exhaust Gas Recirculation Valve iyivalvu elawulwa yi-PCM (I-Powertrain Control Module) evumela amanani alinganiselwe amagesi e-exhaust ukuthi adlule abuyele kumasilinda ukuze ashiswe kanye nengxube yomoya/yamafutha. Ngenxa yokuthi amagesi e-exhaust ayigesi engasebenzi esusa umoya-mpilo, ukuwajova abuyele kusilinda kungehlisa izinga lokushisa elivuthayo, okusiza ukunciphisa ukukhishwa kwe-NOx (nitrogen oxide).

I-EGR ayidingeki ngesikhathi sokuqala esibandayo noma sokufaka idling. I-EGR inikwe amandla ngaphansi kwezimo ezithile, njengokuqala noma idling. Ukuphindiselwa kwegesi ekhishwa kunikezwa ngaphansi kwezimo ezithile, njengokuphenduka okuyingxenye noma ukwehla, kuye ngokushisa kwenjini nomthwalo, njll. Amagesi okukhipha ahlinzekwa ku-valve ye-EGR evela kumbhobho wokukhipha, noma i-valve ye-EGR ingafakwa ngqo kumaningi wokukhipha . Uma kunesidingo, i-valve iyasebenza, ivumela amagesi ukuthi angene kumasilinda. Amanye amasistimu aqondisa amagesi okukhipha ngqo kumasilinda, kanti amanye avele awajoje ezinqwabeni zokungenisa, kusuka lapho adonswa khona kumasilinda. kanti abanye bavele bayijoje ezinhlangothini eziningi zokudla, kusuka lapho bese idonswa kumasilinda.

Ezinye izinhlelo ze-EGR zilula impela, kanti ezinye ziyinkimbinkimbi ngokwengeziwe. Amaphayiphu wokuphinda ugesi aphethwe ugesi alawulwa ngqo yikhompyutha. Ihanisi ixhuma ku-valve uqobo futhi ilawulwa yi-PCM lapho ibona isidingo. Kungaba izintambo ezi-4 noma ezi-5. Ngokujwayelekile izizathu ezi-1 noma ezi-2, isekethe lokushisa elingu-12V, isekethe lesethenjwa elingu-5V, kanye nesekethe yempendulo. Ezinye izinhlelo zilawulwa ngomshini. Iqondile impela. I-PCM ilawula i-vacuum solenoid okuthi, uma ivulwa, ivumele i-vacuum ukuthi iye futhi ivule i-valve ye-EGR. Lolu hlobo lwe-valve ye-EGR kufanele futhi lube nokuxhumeka kagesi kwesekethe yempendulo. I-loop yempendulo ye-EGR ivumela i-PCM ukuthi ibone ukuthi iphini ye-valve ye-EGR empeleni ihamba kahle yini.

Uma iluphu yempendulo ye-EGR "C" ithola ukuthi i-voltage iphansi ngokungavamile noma ingaphansi kwe-voltage eshiwo, i-P044C ingasethwa. Bheka imanuwali ethile yokulungisa imoto yendawo yenzwa ethi "C".

Inzwa ehambelana negesi yokukhipha igesi "C" amakhodi:

• I-P044A Exhaust Gas Recirculation Sensor C Circuit
• I-P044B Exhaust Gas Recirculation Sensor "C" Ibanga Lesekethe / Ukusebenza
• P044D Inani eliphakeme lenzwa "C" yohlelo lokukhipha kabusha igesi
• I-P044E Isifunda senzwa esingaphakathi / esingazinzile se-EGR "C"

izimpawu

Izimpawu zekhodi yenkinga ye-P044C zingafaka:

• Ukukhanya kwe-MIL (Inkomba Yokungasebenzi)

izizathu

Izimbangela ezingenzeka zekhodi ye-P044C zifaka:

• Mfushane phansi emjikelezweni wesiginali we-EGR noma amasekethe wesethenjwa
• Isifunda esifushane kumandla wesekethe womhlaba noma amasekethe wesiginali wohlelo lokukhipha igesi qeda
• I-valve engalungile ye-EGR
• Izinkinga zokufaka izintambo ezimbi ze-PCM ngenxa yamatheminali abraded noma akhululekile

Izixazululo ezingenzeka

Uma ukwazi ukufinyelela ithuluzi lokuskena, ungalawula i-EGR valve ON. Uma iphendula futhi impendulo ikhombisa ukuthi i-valve ihamba kahle, inkinga ingahle ibe ngezikhathi ezithile. Kwesinye isikhathi, esimweni sezulu esibandayo, umswakama ungabanda ku-valve, ubangele ukuthi unamathele. Ngemuva kokufudumeza imoto, inkinga inganyamalala. I-Carbon noma enye imfucumfucu ingabambeka ku-valve ibangele ukuthi inamathele.

Uma i-valve yokukhipha igesi engaphenduli kwimiyalo yethuluzi lokuskena, nqamula isixhumi segesi yokukhipha igesi. Jika ukhiye uye endaweni, injini icishiwe (KOEO). Sebenzisa i-voltmeter ukuhlola u-5 V ekuholeni kokuhlolwa kwe-valve ye-EGR. Uma kungekho volts ama-5, ngabe kukhona amandla kagesi nhlobo? Uma i-voltage ingama-volts ayi-12, lungisa okufushane kuya ku-voltage kusifunda sereferensi se-volt engu-5. Uma kungekho-voltage ekhona, xhuma isibani sokuhlola kumandla ebhethri bese uhlola ucingo lwereferensi engu-5 V. Uma isibani sokuhlola sikhanyisa, isekethe lereferensi elingu-5 V lifinyelelwe phansi. Lungisa uma kunesidingo. Uma isibani sokuhlola singakhanyisi, hlola isekethe lereferensi elingu-5 V ukuze uvuleke. Lungisa uma kunesidingo.

Uma ingekho inkinga esobala futhi ingekho ireferensi ye-volt engu-5, i-PCM ingahle ibe nephutha, kepha amanye amakhodi kungenzeka abekhona. Uma ama-volts ama-5 akhona kusifunda sereferensi, xhuma i-5 volt jumper wire kusifunda sesiginali se-EGR. Ithuluzi lokuskena indawo yokukhipha igesi manje kufanele ifunde amaphesenti ayi-100. Uma ingaxhumi isibani sokuhlola kumthamo webhethri, hlola isekethe yesiginali yokuphindwa kabusha kwegesi yokukhipha. Uma ivuliwe, isifunda sesiginali sifushiselwa phansi. Lungisa uma kunesidingo. Uma inkomba ingakhanyisi, hlola ukuvuleka kwisekethe yesiginali ye-EGR. Lungisa uma kunesidingo.

Uma, ngemuva kokuxhuma isekhethi lereferensi engu-5 V kusiginali yesiginali ye-EGR, ithuluzi lokuskena libonisa indawo ye-EGR engamaphesenti ayi-100, hlola ukungezwani okungalungile kumatheminali esixhumi se-valve se-EGR. Uma i-wiring ilungile, shintsha i-valve ye-EGR.
