Ikhodi Yenkinga ye-OBD-II - P2452 - Ishidi Ledatha

I-P2452 - Isekhethi yenzwa ye-Diesel Particulate Filter Pressure

Isho ukuthini ikhodi yenkinga P2452?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza kuzo zonke izimoto kusukela ngo-1996 (Ford, Dodge, GMC, Chevrolet, Mercedes, VW, njll.). Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Uma imoto yakho ikhombisa inkomba yensiza kungekudala ilandelwa yikhodi P2452, i-powertrain control module (PCM) ithole ukungasebenzi kahle kugesi kagesi we-DPF pressure sensor, obizwa ngo-A. Ngokusobala, le khodi kufanele yethulwe ezimotweni kuphela ngenjini kadizili.

I-DPF yenzelwe ukususa amaphesenti ayisishiyagalolunye ezinhlayiya zekhabhoni (insizi) emagesi aqeda udizili. Umsila uvame ukuhlotshaniswa nentuthu emnyama ephuma emsini wokukhipha lapho injini kadizili ingaphansi kokusheshisa okuqinile. I-DPF ibekwe esikhwameni sensimbi esakhelwe ngaphakathi esifana nesiguquli esingaguquki noma esiguquguqukayo. Itholakala enhla nomguquli wokuguqula kanye / noma noxhaka we-NOx. Ngenkathi izinhlayiya ezinkulu zomsizi zibhajwe entweni ye-DPF, izinhlayiya ezincane namanye amakhemikhali (amagesi e-exhaust) angadlula kuyo. I-DPF isebenzisa izinhlobo ezahlukahlukene zamakhemikhali okubamba umusi nokudlulisa amagesi wokukhipha injini. Lokhu kufaka phakathi iphepha, imicu yensimbi, imicu ye-ceramic, imicu yodonga lwama-silicone, nezintambo zodonga lwe-cordierite.

I-Cordierite iwuhlobo lokuhlunga okusekelwe ku-ceramic kanye nohlobo oluvame kakhulu lwefayibha esetshenziswa kuzihlungi ze-DPF. Ayibizi futhi inezici ezinhle kakhulu zokuhlunga. Ngeshwa, i-cordierite inezinkinga zokuncibilika emazingeni okushisa aphezulu, okuyenza ijwayele ukwehluleka uma isetshenziswa ezinhlelweni zokuhlunga eziyizinhlayiyana.

Inhliziyo yanoma yisiphi isihlungi sezinhlayiya isici sokuhlunga. Lapho i-exhaust yenjini idlula endaweni, izinhlayiya ezinkulu ze-soot zivaleleka phakathi kwemicu. Njengoba i-soot ikhula, umfutho wegesi yokukhipha ukhuphuka ngokufanele. Uma umule owanele usuqoqiwe (futhi nomfutho we-exhaust usufinyelele izinga elihleliwe), isici sokuhlunga kufanele sivuselelwe ukuze kuvunyelwe amagesi e-exhaust ukuthi aqhubeke edlula ku-DPF.

Izinhlelo ezisebenzayo ze-DPF zivuselelwa ngokuzenzakalela. Ngamanye amagama, i-PCM ihlelelwe ukufaka amakhemikhali (kufaka phakathi kepha kungagcini kudizili nokukhipha uketshezi) kumagesi okukhipha ngezikhathi ezihleliwe. Lesi senzo senza ukuthi izinga lokushisa kwamagesi okukhipha umoya likhuphuke futhi izinhlayiya zomsizi ezibhajwe zishiswe; ukuzikhulula ngesimo se-nitrogen ne-oxygen ions.

Inqubo efanayo isetshenziswa ezinhlelweni ezingenzi lutho ze-DPF, kepha idinga ukubandakanyeka komnikazi futhi (kwezinye izimo) umlungisi oqeqeshiwe. Ngemuva kokuqala kwenqubo yokuvuselela, kungathatha amahora ambalwa. Ezinye izinhlelo zokuvuselela okungenzi lutho zidinga ukuthi i-DPF isuswe emotweni futhi ihlinzekwe ngumshini okhethekile oqeda inqubo futhi asuse kahle izinhlayiya zomsizi. Lapho izinhlayiya zomsizi zisuswe ngokwanele, i-DPF ibhekwa njengokuvuselelwa futhi ingcindezi ye-exhaust kufanele iphendule ngokufanele.

Ezimweni eziningi, inzwa yengcindezi ye-DPF ifakwa egumbini lenjini, kude ne-DPF. Ihlola ingcindezi yangemuva yamagesi aqeda ngaphambi kokufaka isihlungi se-particulate. Lokhu kutholakala ngamathumbu abicah (okukodwa noma ngaphezulu) axhunywe kwi-DPF (eduze ne-inlet) kanye ne-DPF sensor sensor.

Lapho i-PCM ithola isimo sengcindezi yokukhipha engekho ngaphakathi kokucacisiwe komkhiqizi, noma okokufaka kagesi okuvela ku-DPF Inzwa yokucindezela kudlula imikhawulo ehleliwe, ikhodi ye-P2452 izogcinwa futhi isibani senjini yensizakalo sizokhanyisa kungekudala.
