NkeNnwale EVAP (Sistemụ Njikwa Emume).bụ ọrụ nyocha onwe onye dị oke egwu n'ime ụgbọ ala OBD2 kwadoro. Ọ na-ahụ na sistemu ikuku nke mmanụ ọkụ na-arụ ọrụ nke ọma, na-egbochi ikuku hydrocarbon na-emerụ ahụ ịba n'ime ikuku. Nke a bụ ndakpọ nkenke nke ọrụ ya, iji ikpe, yana data enwere ike ime maka ndị ọkwọ ụgbọ ala kwa ụbọchị:
1. EVAP System Test Ọrụ
- Ebumnuche: Na-achọpụta nkwụsị ma ọ bụ adịghị arụ ọrụ n'ime sistemu uzuoku mmanụ (dịka ọmụmaatụ, tank mmanụ, okpu gas, ite unyi, valves, hoses).
- Ụzọ:
- Nnwale nrụgide/Vacuum: Na-enyocha nrụgide/ọkwa agụụ iji chọpụta ntapu (dịka ọmụmaatụ, okpu gas rụrụ arụ).
- Akara iguzosi ike n'ezi ihe nlele: Na-akwado ihe ndị dị ka valvụ na-ehichapụ na ikuku solenoids.
- Nchọpụta ntakiri ntakiri: Na-achọpụta ntapu ka obere ka0.020 sentimita (0.5 mm)na dayameta.
2. Ihe ndị a na-ejikarị eme ihe
- Nnwale onwe onye oge niile: A na-eme ya na akpaghị aka n'oge okirikiri ịnya ụgbọ ala (dịka ọmụmaatụ, mgbe ịgbanye mmanụ, ịnya ụgbọ ala kwụ ọtọ).
- Lelee Nnụnụ ọkụ na-akpalite: Na-arụ ọrụ mgbe achọpụtara ntapu ma ọ bụ mmejọ (dịka ọmụmaatụ, valvụ nhicha na-adịghị mma, eriri gbawara agbawa) achọpụtara.
- Nyochaa mmezigharị mgbe emechara: Na-akwado ndozi ka ọ kwuchara okwu metụtara EVAP.
3. Isi ihe data maka ndị nwe ụgbọ ala
- Koodu mmejọ (DTCs):
- P0442/P0455: Na-egosi obere ntapu / nnukwu (dịka ọmụmaatụ, okpu gas rụrụ arụ, eriri gbawara agbawa).
- P0446/P0496: Na-atụ aro ventilashị/sachapụ valvụ nsogbu.
- Ọgụgụ Ọgụgụ Mmanụ Ala: Ụkpụrụ na-adịghị mma nwere ike igosi ntapu ma ọ bụ ọdịda akụrụngwa.
- Mkpu okpu gas: na-adọ aka ná ntị ozugbo maka akara na-ezighi ezi (okwu a na-ahụkarị, nke a na-edozi ngwa ngwa).
- Ọnọdụ ule: Na-akwado ma ọ bụrụ na ihe nleba anya EVAP “zuola” (dị njikere maka nnwale ikuku).
Ihe Mere Nke a Ji Dị Ndị Ọkwọ ụgbọala Ihe
- Nchekwa ọnụ ahịa: Nchọpụta mbụ nke obere okwu (dịka ọmụmaatụ, mwepu okpu gas) na-egbochi nrụzi dị oke ọnụ.
- Nkwekọrịta ikuku: Gbaa mbọ hụ na ụgbọ gị gafere nyocha smog amanyererịrị.
- Mmetụta gburugburu ebe obibi: Na-ebelata mmetọ hydrocarbon site na vapors mmanụ ụgbọala.
Ndụmọdụ Pro: Ọ bụrụ na ọkụ igwe nlele apụta, buru ụzọ lelee okpu gas. Ọ bụrụ na agbasie ike na ọkụ na-aga n'ihu, jiri nyocha OBD2 weghachite koodu maka nchọpụta nsogbu ezubere iche.
Ihe data a na-enye ndị nwe ikike ileba anya obere nsogbu nke ọma, zere nyocha ndị dara ada, ma jikwaa ma arụmọrụ ụgbọ ala yana nnabata gburugburu ebe obibi.
