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.

Haeba koloi ea hau e bontša enjene khoutu ea tšebeletso ea P245E haufinyane, module ea powertrain control module (PCM) e lemohile ho se sebetse hantle ho potoloho ea motlakase ea senotlolo sa khatello ea DPF, se khethiloeng B. Ho hlakile hore khoutu ena e lokela ho hlahisoa feela ka makoloi a nang le disele enjene.

DPF e etselitsoe ho tlosa liperesente tse mashome a robong a likaroloana tsa khabone (mosili) ho tsoa likhasong tse fehlang motlakase. Soot hangata e amahanngoa le mosi o motšo o nyolohang mosi oa mokelikeli ha enjene ea dizeli e le tlasa matsapa a matla. DPF e lutse kahare ea tšepe e hahelletsoeng kahare e ts'oanang le mofetoleli o sa fetoheng. E fumaneha noka ea mofetoleli oa catalytic le / kapa leraba la NOx. Ha likaroloana tse kholo tsa mosili li qabeletsoe nthong ea DPF, likaroloana tse nyane le metsoako e meng (likhase tsa ho qeta) li ka feta ho eona. DPF e sebelisa mefuta e fapaneng ea metsoako ea mantlha ho ts'oara mosili le ho fetisa likhase tsa ho ntša enjene. Tsena li kenyelletsa pampiri, likhoele tsa tšepe, likhoele tsa ceramic, likhoele tsa mabone tsa silicone le likhoele tsa mabota a cordierite.

Cordierite ke mofuta oa filtration e thehiloeng ho ceramic le mofuta o atileng haholo oa fiber o sebelisoang ho lifilthara tsa DPF. E batla e le theko e tlase mme e na le litšobotsi tse ntle haholo tsa ho sefa. Ka bomalimabe, cordierite e na le mathata a ho qhibiliha mochesong o phahameng, e leng se etsang hore e senyehe habonolo ha e sebelisoa lits'ebetsong tsa li-filter tse sa sebetseng.

Pelo ea sefe kapa sefe sa particulate ke karolo ea sefe. Ha mosi oa enjene o feta har'a element, likaroloana tse kholo tsa soot li qabeletsoe lipakeng tsa likhoele. Ha mosi o ntse o eketseha, khatello ea khase ea mouoane e eketseha ka ho loketseng. Hang ha mosili o lekaneng o se o bokeletse ('me khatello ea mouoane e fihlile tekanyong e hlophisitsoeng), karolo ea sesefe e tlameha ho nchafatsoa ho lumella likhase tsa mouoane hore li tsoele pele ho feta DPF.

Sistimi e sebetsang ea DPF e itlhahisa ka bo eona. '' Ketso ena e etsa hore mocheso oa likhase tsa ho qeta o nyolohe 'me likaroloana tsa mosili tse qabeletsoeng li chesoe; ho li lokolla ka mokhoa oa naetrojene le li-ion tsa oksijene.

Ts'ebetso e ts'oanang e sebelisoa lits'ebetsong tse sa sebetseng tsa DPF, empa e hloka ho nka karolo ha mong'a eona le (maemong a mang) ho lokisa e tšoanelehang. Kamora ho qala ha ts'ebetso ea nchafatso, ho ka nka lihora tse 'maloa. Lits'ebetso tse ling tsa nchafatso li hloka hore DPF e tlosoe ka koloing ebe e sebeletsoa ke mochini o ikhethileng o phethelang tšebetso le ho tlosa likaroloana tsa mosili hantle. Ha likaroloana tsa mosili li tlositsoe ka ho lekana, DPF e nkuoa e nchafalitsoe mme khatello ea mokhathala e tlameha ho arabela hantle.

Maemong a mangata, senotlolo sa khatello ea DPF se kentsoe ka phapusing ea enjene, hole le DPF. E lekola khatello ea morao ea likhase tsa ho qeta pele li kenella mohloeng oa likaroloana. Sena se fihlelleha ka li-hose tsa silicone tse (ngoe kapa ho feta) tse hokahantsoeng le DPF (haufi le lesoba) le senotlolo sa khatello ea DPF.

Ha PCM e lemoha khatello ea khatello ea mocheso e sa lumellaneng le litlhaloso tsa moetsi, kapa motlakase o tsoang ho DPF B khatello ea sensor e feta meeli e hlophisitsoeng, khoutu ea P245E e tla bolokoa mme lebone la enjene ea ts'ebeletso le tla bonesa haufinyane.

Mekhoa ea ho hlahloba le ho lokisa

Ntho e ntle eo u ka qalang ho eona kamehla ke ho lekola bulletins ea lits'ebeletso tsa tekheniki (TSB) bakeng sa koloi ea hau. Bothata ba hau e ka ba bothata bo tsebahalang ka tokiso e tsebahalang e hlahisitsoeng ke moetsi mme e ka u bolokela nako le chelete nakong ea tlhahlobo.

Ho fumana khoutu ea P245E, o tla hloka sesebelisoa sa ho hlahloba, volt / ohmmeter ea dijithale, le buka ea litšebeletso ho tsoa ho moetsi. Thermometer ea infrared le eona e ka sebetsa hantle.

Ke tloaetse ho qala tlhahlobo ea ka ka ho hlahloba ka mahlo lihokelo le likhokelo tse amanang. Ke ne ke tla ela hloko ka ho khetheha mohala o tsamaisoang haufi le likarolo tsa mocheso o chesang le likhahla tse bohale. Lekola boemelong ba betri le betri ka nako ena 'me u hlahlobe tlhahiso ea jenereithara.

Eaba ke hokahanya sekena mme ka fumana likhoutu tsohle tse bolokiloeng mme ka emisa data ea foreimi. Ke ne ke ngola sena fatše hore ke se sebelise nakong e tlang. Sena se ka sebetsa habonolo haeba khoutu ena e ka ba ea nakoana. Joale hlakola likhoutu le teko ho khanna koloi.

Haeba khoutu e seta bocha hanghang, netefatsa hore mokelikeli oa mokelikeli oa enjene ea disele o teng (haeba ho hlokahala) le hore na ke oa mofuta o nepahetseng. Lebaka le tloaelehileng haholo la hore khoutu ena e bolokoe ke khaello ea mokelikeli oa enjene ea dizeli. Ntle le mofuta o nepahetseng oa mokelikeli oa enjene ea disele, DPF e ke ke ea nchafatsoa ka nepo, e lebisang ho keketseho e ka bang teng ea khatello ea khatello.

Sheba bukana ea litšebeletso tsa moetsi bakeng sa litaelo tsa hore na u ka leka senotlolo sa khatello ea DPF joang u sebelisa DVOM. Haeba sensor e sa fihlelle litlhoko tsa moetsi, e tlameha ho nkeloa sebaka. Haeba sensor e lokile, hlahloba li-hoses tsa phepelo ea khatello ea DPF bakeng sa li-blockages le / kapa break. Hloekisa kapa u tlose li-hoses ha ho hlokahala. Ho lokela ho sebelisoa liphaephe tse phahameng tsa silicone.

Haeba sensor e le ntle 'me likhoele tsa motlakase li le hantle, qala ho leka lipotoloho tsa sisteme. Tlosa li-module tsohle tse amanang le taolo pele u etsa liteko tsa ho hanyetsa le / kapa ho tsoela pele ka DVOM. Lokisa kapa u khutlisetse lipotoloho tse bulehileng kapa tse khutšoane ha ho hlokahala.

Lintlha tse ling tsa ho hlahloba:

• Haeba li-hose tsa khatello ea DPF li qhibilihile kapa li petsohile, ho kanna ha hlokahala hore u tsamaee bocha kamora ho nkeloa sebaka.
• Ikopanye le buka ea beng ba litšebeletso ho fumana hore na koloi ea hau e na le sistimi e nchafatsang ea DPF kapa sistimi e sa sebetseng.
