Menene ma'anar lambar matsala P2454?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi duk abin hawa tun 1996 (Ford, Dodge, GMC, Chevrolet, Mercedes, VW, da sauransu). Kodayake gabaɗaya a yanayi, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.

Na gano cewa yayin adana lambar P2454, tsarin sarrafa wutar lantarki (PCM) ya gano ƙarancin shigar da ƙarfin lantarki daga keɓaɓɓen firikwensin matsa lamba na DPF da aka ƙaddara A. Kawai motocin da ke da injunan diesel ya kamata su sami wannan lambar.

An ƙera shi don cire kashi casa'in na carbon (soot) barbashi daga sharar diesel, tsarin DPF yana zama cikin sauri cikin motocin dizal. Diesel injuna (musamman a babban hanzari) suna fitar da hayaƙi mai kauri daga gas ɗin su. Ana iya rarrabasu azaman toka. DPF yawanci yana kama da murfi ko mai jujjuyawa, wanda aka saka a cikin gidan ƙarfe kuma yana can sama na mai jujjuyawa (da / ko tarkon NOx). Ta hanyar ƙira, ƙananan ɓoyayyun ɓoyayyun abubuwa sun makale a cikin ɓangaren DPF, yayin da ƙananan ƙwayoyin (da sauran mahaɗan shaye -shaye) na iya wucewa ta ciki.

A halin yanzu ana amfani da mahadi da yawa don tarko manyan barbashi daga iskar gas mai guba. Waɗannan na iya haɗawa da: firam ɗin takarda, firam ɗin ƙarfe, firam ɗin yumbu, firam ɗin bangon silicone, da fibers na bango. Cordierite-tushen yumbu shine mafi yawan nau'in fiber da ake amfani dashi a cikin matatun DPF. Cordierite yana da kyawawan halaye na tacewa kuma ba shi da tsada don ƙerawa. Koyaya, cordierite an san yana da matsaloli tare da zafi fiye da kima a yanayin zafi mafi girma, yana sa ya zama mai rauni ga rashin aiki a cikin motocin da aka sanye da tsarin matattara mai rarrafe.

A zuciyar kowane DPF shine abun tace. Manyan ɓoyayyen toka suna makale tsakanin fibers yayin da iskar gas ɗin injin ke wucewa. Yayin da barbashi mai taushi ke taruwa, matsin lamba yana ƙaruwa. Bayan matsin iskar gas ya kai matakin da aka tsara, dole ne a sake sabunta abin tace. Sabuntawa yana ba da damar iskar gas don ci gaba da wucewa ta cikin DPF da kuma kula da matakin matsin lamba daidai.

Tsarin DPF masu aiki suna sabuntawa ta atomatik. A cikin wannan nau'in tsarin, PCM an tsara shi don allurar sunadarai (gami da amma ba'a iyakance ga dizal da ruwa mai ɗorewa) a cikin DPF a cikin shirye -shiryen da aka tsara. Wannan allurar da aka sarrafa ta hanyar lantarki yana haifar da zafin zafin iskar gas ɗin da ke tashi, yana barin barbashin soyayyar da ke makare ya ƙone kuma a sake shi azaman ions nitrogen da oxygen.

Tsarin DPF mai wucewa iri ɗaya ne (a ka'idar) amma yana buƙatar wasu bayanai daga mai aiki. Da zarar an fara, tsarin sabuntawar na iya ɗaukar awanni da yawa. Wasu ababen hawa suna buƙatar ƙwararren shagon gyara don tsarin sabuntawa. An ƙera wasu samfuran ta hanyar da dole ne a cire DPF daga abin hawa kuma a yi aiki da injin na musamman wanda ke kammala aikin kuma yana cire barbashin ƙura.

Da zarar an cire ɓoyayyen ɓoyayyen isasshen, ana ɗaukar DPF ya sake haihuwa. Bayan sabuntawa, matsin lamba na baya ya kamata ya koma matakin karɓaɓɓe.

Ana shigar da firikwensin matsa lamba na DPF a cikin injin injin kuma nesa da DPF. Ana lura da matsin lamba ta baya ta firikwensin (lokacin da ya shiga DPF) ta amfani da bututun silicone (wanda aka haɗa da DPF da firikwensin matsa lamba na DPF).

Za a adana lambar P2454 idan PCM ta gano yanayin matsin lamba wanda ke ƙasa da ƙayyadaddun masana'anta, ko shigarwar lantarki daga firikwensin matsa lamba na DPF A wanda ke ƙasa da iyakokin da aka tsara.
