IUvavanyo lwe-EVAP (iNkqubo yoLawulo lwe-Evaporative Emission).ngumsebenzi obalulekileyo wokuzixilonga kwiimoto ezihambelana ne-OBD2. Iqinisekisa ukuba inkqubo yokuqulatha umphunga wepetroli isebenza ngokufanelekileyo, ikhusela ukukhutshwa kwehydrocarbon eyingozi ekuphunyukeni emoyeni. Nalu ucazululo olufutshane lokusebenza kwayo, iimeko zokusetyenziswa, kunye nedatha enokuthatyathwa kubaqhubi bemihla ngemihla:
1. Umsebenzi woVavanyo lweNkqubo ye-EVAP
- Injongo: Ukukhangela iindawo ezivuzayo okanye ukungasebenzi kakuhle kwisixokelelwano somphunga wamafutha (umzekelo, itanki yamafutha, ikepusi yegesi, ingqayi yamalahle, iivalvu, imibhobho).
- Iindlela:
- Uvavanyo loxinzelelo / lweVacuum: Ubeka iliso kuxinzelelo/amanqanaba evacuum ukuchonga iindawo ezivuzayo (umzekelo, umnqwazi werhasi).
- Itywina Iitshekhi Ingqibelelo: Iqinisekisa amacandelo afana neevalvu zokucoca kunye ne-solenoids ye-vent.
- Ukufunyanwa kokuvuza okuncinci: Uchonga ukuvuza kuncinci njenge0.020 intshi (0.5 mm)ububanzi.
2. Iimeko zokusetyenziswa okuqhelekileyo
- Ukuzivavanya ngokwesiqhelo: Yenziwa ngokuzenzekelayo ngexesha lemijikelo ethile yokuqhuba (umzekelo, emva kokugalela amafutha, ukuqhuba ngesantya esizinzileyo).
- Jonga i-Engine Light Triggers: Yenziwa isebenze xa ukuvuza okanye iziphene (umzekelo, ivalve yokucoca enempazamo, ithumbu eliqhekekileyo) zibhaqwe.
- Ukuqinisekiswa kwasemva kokulungisa: Iqinisekisa izilungiso emva kokujongana nemiba enxulumene ne-EVAP.
3. IiNgcaciso zeNgcaciso eziPhambili kuBanini beZithuthi
- Iikhowudi zeempazamo (DTCs):
- P0442/P0455: Ibonisa ukuvuza okuncinci/okukhulu (umzekelo, umnqwazi werhasi oxekileyo, umbhobho oqhekekileyo).
- P0446/P0496: Cebisa imiba yevalvu yokuphuma/yokucoca.
- Ufundo lweTanki yeFuel ngoxinzelelo: Amaxabiso angaqhelekanga angabonisa ukuvuza okanye ukusilela kwecandelo.
- Izilumkiso zeGas Cap: Ilumkisa ngokuthe ngqo ngokutywinwa okungafanelekanga (umcimbi oqhelekileyo, onokulungiseka ngokulula).
- Ubume boVavanyo: Iqinisekisa ukuba i-EVAP monitor "igqityiwe" (ilungele uvavanyo lokukhutshwa kwezinto ezikhutshwayo).
Kutheni Oku Kubalulekile Kubaqhubi
- Ugcino lweendleko: Ukufunyaniswa kwangethuba kwemiba emincinci (umzekelo, ukuvuza kwegesi) kuthintela ukulungiswa okuneendleko eziphezulu.
- Ukuthotyelwa kweMishini: Iqinisekisa ukuba isithuthi sakho siyaphumelela kwiitshekhi zesmog.
- Impembelelo yokusingqongileyo: Yehlisa ungcoliseko lwehydrocarbon kumphunga wamafutha.
Ingcebiso yePro: Ukuba ukukhanya kwe-injini yokukhangela kubonakala, jonga kuqala i-cap yegesi. Ukuba iqinisiwe kwaye ukukhanya kuyaqhubeka, sebenzisa iskena se-OBD2 ukufumana iikhowudi zokusombulula ingxaki.
Le datha ixhobisa abanini ukuba bajongane nemiba emincinci ngokukhawuleza, baphephe ukuhlolwa okungaphumelelanga, kunye nokugcina ukusebenza kwezithuthi kunye nokuthotyelwa kokusingqongileyo.
