TheTlhahlobo ea EVAP (Evaporative Emission Control System).ke ts'ebetso ea bohlokoa ea ho itlhahloba likoloing tse lumellanang le OBD2. E etsa bonnete ba hore mokhoa oa ho thibela mouoane oa mafura o sebetsa hantle, ho thibela mesi e kotsi ea hydrocarbon hore e se ke ea kena sepakapakeng. Mona ke karohano e khuts'oane ea ts'ebetso ea eona, linyeoe tsa ts'ebeliso, le data e sebetsang bakeng sa bakhanni ba letsatsi le letsatsi:
1. Mosebetsi oa Tlhahlobo ea Tsamaiso ea EVAP
- Morero: E lemoha ho dutla kapa ho se sebetse hantle ha mouoane oa mafura (mohlala, tanka ea mafura, sekoahelo sa khase, sekoti sa mashala, li-valve, li-hose).
- Mekhoa:
- Teko ea Khatello / Vacuum: E beha leihlo maemo a khatello / vacuum ho tseba moo ho lutlang (mohlala, sekoaelo sa khase se hlephileng).
- Tiisa Botšepehi Licheke: E netefatsa likarolo tse kang li-valve tsa ho hloekisa le li-solenoids tsa vent.
- Ho Fumana Leak e Nyane: E hlwaya marotho a manyane jwaloka0.020 inches (0.5 mm)ka bophara.
2. Maemo a Tšebeliso e Tloaelehileng
- Boitlhahlobo ba Ka mehla: E etsoa ka boiketsetso nakong ea lipotoloho tse itseng tsa ho khanna (mohlala, ka mor'a ho tlatsa mafura, ho khanna ka lebelo le tsitsitseng).
- Hlahloba Engine Light Triggers: E ea sebetsa ha ho lutla kapa ho na le liphoso (mohlala, valve e nang le phoso ea ho hloekisa, hose e phatlohileng) e bonoa.
- Netefatso ea Kamora ho Lokisa: E netefatsa litokiso ka mor'a ho rarolla mathata a amanang le EVAP.
3. Lintlha tsa Lintlha tsa Bohlokoa Bakeng sa Beng ba Likoloi
- Likhoutu tsa Phoso (DTCs):
- P0442/P0455: E bonts'a ho lutla ha nyane/ ho hoholo (mohlala, kepisi ea khase e hlephileng, hose e phatlohileng).
- P0446/P0496: E fana ka maikutlo a litaba tsa li-valve tsa vent / purge.
- Lipalo tsa Khatello ea Tanka ea Mafura: Maemo a sa tlwaelehang a ka bontsha ho dutla kapa ho hloleha ha dikarolo.
- Litlhokomeliso tsa Cap ea Khase: E lemosa ka ho toba ka tiiso e fosahetseng (taba e tloaelehileng, e ka lokisoang habonolo).
- Boemo ba Teko: E netefatsa haeba sehlahlobi sa EVAP se "felletse" (se se se loketse tlhahlobo ea mesi).
Ke Hobane'ng ha Sena se le Bohlokoa ho Bakhanni
- Ho Boloka Litšenyehelo: Ho lemoha mathata a sa reng letho (mohlala, ho lutla ha khase) ho thibela ho lokisoa ho bitsang chelete e ngata.
- Emission Compliance: E netefatsa hore koloi ea hau e feta litlhahlobo tse tlamang tsa mosi.
- Tšusumetso ea Tikoloho: E fokotsa tšilafalo ea hydrocarbon ho tsoa mouoane oa mafura.
Pro Tip: Haeba lebone la enjene la cheke le hlaha, qala ka ho hlahloba sekoahelo sa khase. Haeba e tiisitsoe 'me leseli le phehella, sebelisa sekena sa OBD2 ho fumana likhoutu bakeng sa ho rarolla mathata.
Lintlha tsena li matlafatsa beng ba tsona ho rarolla mathata a manyane ka potlako, ho qoba tlhahlobo e hlolehileng, le ho boloka ts'ebetso ea likoloi le ho latela tikoloho.
