TheEVAP (Evaporative Emission Control System) mayesondi ntchito yovuta yodzizindikiritsa yokha m'magalimoto ogwirizana ndi OBD2. Imawonetsetsa kuti mpweya wamafuta umagwira ntchito moyenera, kuletsa mpweya woipa wa hydrocarbon kuti usatulukire mumlengalenga. Nayi kufotokozedwa mwachidule kwa magwiridwe ake, zochitika zogwiritsiridwa ntchito, ndi zomwe zingachitike kwa oyendetsa tsiku ndi tsiku:
1. EVAP System Test Ntchito
- Cholinga: Imazindikira kuchucha kapena kusokonekera kwa mpweya wamafuta (monga thanki yamafuta, chivundikiro cha gasi, chibotolo cha makala, mavavu, mapaipi).
- Njira:
- Kuyesa kwa Pressure/Vacuum: Imayang'anira kuchuluka kwa mphamvu / vacuum kuti izindikire kutayikira (mwachitsanzo, kapu ya gasi yotayirira).
- Macheke a Seal Integrity: Imatsimikizira zinthu monga ma valve oyeretsa ndi ma solenoids.
- Kuzindikira Kutayikira kwakung'ono: Imazindikiritsa kutulutsa kochepa ngati0.020 mainchesi (0.5 mm)m'mimba mwake.
2. Zochitika Zogwiritsidwa Ntchito Wamba
- Kudziyesa Mwachizolowezi: Amachita zodziwikiratu pakayendetsedwe kake (mwachitsanzo, mutatha kuthira mafuta, kuyendetsa mwachangu).
- Onani Zoyambitsa Kuwala kwa Injini: Amayatsidwa pamene kudontha kapena zolakwika (mwachitsanzo, valavu yoyeretsa yolakwika, payipi yosweka) yazindikirika.
- Kutsimikizira Pambuyo Pokonza: Imatsimikizira zokonza pambuyo pothana ndi zovuta zokhudzana ndi EVAP.
3. Mfundo Zofunika Kwambiri za Eni Magalimoto
- Makodi Olakwika (DTCs):
- P0442/P0455: Imawonetsa kudontha kwakung'ono/kwakukulu (monga chipewa cha gasi chosasunthika, payipi yosweka).
- P0446/P0496: Imawonetsa zovuta za valve yotuluka / kutsuka.
- Kuwerengera Kupanikizika kwa Tanki Yamafuta: Zolakwika zimatha kuwonetsa kutayikira kapena kulephera kwazinthu.
- Zochenjeza za Gasi: Imachenjeza mwachindunji za kusindikiza kosayenera (nkhani wamba, yokhoza kutheka mosavuta).
- Mayeso: Imatsimikizira ngati polojekiti ya EVAP ndi "yathunthu" (yakonzeka kuyesa kutulutsa mpweya).
Chifukwa Chake Izi Ndi Zofunika kwa Madalaivala
- Kupulumutsa Mtengo: Kuzindikira msanga zazovuta zazing'ono (mwachitsanzo, kutuluka kwa mpweya) kumalepheretsa kukonza kodula.
- Kutsata kwa Emission: Imawonetsetsa kuti galimoto yanu yadutsa cheke chovomerezeka cha utsi.
- Environmental Impact: Amachepetsa kuwonongeka kwa hydrocarbon kuchokera ku nthunzi yamafuta.
Pro Tip: Ngati cheke injini kuwala kuonekera, choyamba yang'anani kapu gasi. Ngati akhwimitsidwa ndipo kuwala kukupitilira, gwiritsani ntchito sikani ya OBD2 kuti mutenge ma code omwe mukufuna kuthana nawo.
Izi zimathandizira eni ake kuthana ndi mavuto ang'onoang'ono mwachangu, kupewa kuwunika kolephera, komanso kusunga magwiridwe antchito agalimoto komanso kutsata chilengedwe.
