P2454 - Sefa sa Diesel Particulate A Sensor Sensor Circuit Low

Khoutu ea mathata P2454 e bolela'ng?

Khoutu ena ea Mathata a Tlhatlhobo (DTC) ke khoutu ea phetisetso e akaretsang, ho bolelang hore e sebetsa ho makoloi ohle ho tloha ka 1996 (Ford, Dodge, GMC, Chevrolet, Mercedes, VW, jj.). Le ha e le ka kakaretso, mehato e ikhethileng ea ho lokisa e ka fapana ho latela mofuta / mofuta.

Ke fumane hore ha e ntse e boloka khoutu P2454, module ea powertrain control module (PCM) e fumane motlakase o tlase ho tsoa ho potoloho ea khatello ea khatello ea DPF e khethiloeng A. Ke likoloi feela tse nang le lienjine tsa disele tse lokelang ho ba le khoutu ena.

E etselitsoe ho tlosa liperesente tse mashome a robong a khase ea carbon (soot) ho tsoa ho dizeli, litsamaiso tsa DPF li se li fetoha tloaelo ho likoloi tsa disele. Lienjiniere tsa disele (haholoholo ka lebelo le phahameng) li ntša mosi o motšo o motšo ho tsoa likhase tsa tsona tsa ho qeta. E ka khetholloa e le mosili. DPF hangata e tšoana le mofetoleli oa moferefere kapa o thusang, o kentsoeng ka matlong a tšepe 'me o le kaholimo ho mofetoleli oa catalytic (le / kapa NOx sefi). Ka boqapi, likaroloana tsa mosili tse mahoashe li qabeletsoe karolong ea DPF, ha likaroloana tse nyane (le metsoako e meng ea ho qeta) li ka feta ho eona.

Lik'hemik'hale tse 'maloa tsa hona joale li sebelisetsoa ho tšoasa likaroloana tse kholo tsa mosili ho tsoa likhasineng tsa ho ntša disele. Tsena li ka kenyelletsa: likhoele tsa pampiri, likhoele tsa tšepe, likhoele tsa ceramic, likhoele tsa lebota tsa silicone le likhoele tsa lebota tsa cordierite. Ceramic-based cordierite ke mofuta o atileng ka ho fetisisa oa fiber o sebelisoang ho li-filters tsa DPF. Cordierite e na le litšobotsi tse ntle haholo tsa ho sefa, 'me ha e theko e tlaase ho e etsa. Leha ho le joalo, cordierite e tsejoa e na le mathata a ho chesa haholo maemong a phahameng a mocheso, e leng se etsang hore e be tlokotsing ea ho se sebetse hantle likoloing tse nang le litsamaiso tse sa sebetseng tsa likaroloana.

Ka pelong ea DPF efe kapa efe ho na le karolo ea sefa. Likarolo tse kholo tsa mosili li qabeletsoe lipakeng tsa likhoele ha likhase tsa ho qeta enjene li feta. Ha likaroloana tsa mosili tse mahoashe li bokellana, khatello ea mokhathala e ea eketseha. Kamora khatello ea khase e qeta ho fihla boemong bo hlophisitsoeng, karolo ea sefa e tlameha ho nchafatsoa. Ntjhafatso e lumella likhase tse tsoang ho moea ho tsoela pele ho feta DPF le ho boloka khatello e nepahetseng ea khatello ea ho qeta.

Sistimi e sebetsang ea DPF e itlhahisa ka bo eona. Mofuteng ona oa sistimi, PCM e etselitsoe ho kenya lik'hemik'hale (ho kenyeletsoa empa ho sa lekanyetsoe ho disele le ho qeta mokelikeli) ho DPF nako le nako. Ente ena e laoloang ka elektroniki e etsa hore mocheso oa likhase tsa moea o nyolohe, o lumelle masale a qabeletsoeng hore a chese ebe a lokolloa joalo ka li-ion tsa naetrojene le oksijene.

Mekhoa ea Passive DPF ea tšoana (ka mohopolo) empa e hloka maikutlo a tsoang ho mosebelisi. Ha e se e qalile, ts'ebetso ea nchafatso e ka nka lihora tse 'maloa. Likoloi tse ling li hloka lebenkele le tšoanelehang la ho lokisa bakeng sa ts'ebetso ea nchafatso. Meetso e meng e entsoe ka tsela eo DPF e tlamehang ho tlosoa ka koloing ebe e sebeletsoa ke mochini o ikhethileng o phethelang tšebetso le ho tlosa masela a mosili.

Hang ha likaroloana tsa mosili li tlosoa ka ho lekana, DPF e nkuoa e nchafalitsoe. Kamora ho nchafatsoa, ​​khatello ea mokokotlo ea mokhathala e lokela ho khutlela boemong bo amohelehang.

Hangata sensor ea khatello ea DPF e kentsoe ka phapusing ea enjene ebile e hole le DPF. Khatello ea mokokotlo oa mokhathala e shebiloe ke sensor (ha e kenella DPF) e sebelisa li-hose tsa silicone (tse hokahantsoeng le sensor ea khatello ea DPF le DPF).

Khoutu ea P2454 e tla bolokoa haeba PCM e fumana khatello ea khatello e tlasa maemo a moetsi, kapa motlakase o tsoang ho DPF A khatello ea khatello e ka tlase ho meeli e hlophisitsoeng.
