UwitekaIkizamini cya EVAP (Evaporative Emission Control Sisitemu) ikizamininigikorwa gikomeye cyo kwisuzumisha mumodoka ya OBD2 yujuje. Iremeza ko uburyo bwo kubika imyuka ya peteroli ikora neza, ikarinda imyuka ya hydrocarubone yangiza guhungira mu kirere. Hano haribice bigufi byimikorere yabyo, koresha imanza, hamwe nibikorwa bifatika kubashoferi ba buri munsi:
1. Imikorere yikizamini cya sisitemu ya EVAP
- Intego: Itahura imyanda cyangwa imikorere mibi muri sisitemu ya lisansi (urugero, igitoro cya lisansi, igitoro cya gaze, amakara yamakara, indangagaciro, ama shitingi).
- Uburyo:
- Kwipimisha / Kwipimisha Vacuum: Gukurikirana umuvuduko / urwego rwa vacuum kugirango umenye ibimeneka (urugero, capa ya gaze irekuye).
- Kugenzura Ikimenyetso Cyuzuye: Yemeza ibice nka purge valve na vent solenoids.
- Kumenya Gutoya: Kumenya ibimeneka nkibito nkaSantimetero 0,020 (0,5 mm)diameter.
2. Gukoresha Rusange
- Kwipimisha Kumurongo: Byikora byakozwe mugihe cyihariye cyo gutwara (urugero, nyuma yo kongeramo lisansi, gutwara-byihuta).
- Reba moteri yumucyo: Bikoreshejwe mugihe hamenyekanye cyangwa amakosa (urugero, isuku ya valve idakwiriye, hose yamenetse).
- Kugenzura nyuma yo gusanwa: Yemeza gukosorwa nyuma yo gukemura ibibazo bijyanye na EVAP.
3. Ingingo zingenzi zamakuru kuri banyiri ibinyabiziga
- Kode Yamakosa (DTCs):
- P0442 / P0455: Yerekana ibintu bito / binini bitemba (urugero, gaze ya gaze irekuye, hose yacitse).
- P0446 / P0496: Tanga ibitekerezo bya vent / purge ibibazo.
- Ibikomoka kuri peteroli: Indangagaciro zidasanzwe zishobora kwerekana ibimenyetso bitemba cyangwa ibice byananiranye.
- Imenyekanisha rya gazi: Iraburira mu buryo butaziguye kashe idakwiye (ikibazo gisanzwe, cyoroshye gukosorwa).
- Imiterere y'Ikizamini: Yemeza niba monitor ya EVAP "yuzuye" (yiteguye gupima ibyuka).
Impamvu Ibi Bifite Abashoferi
- Kuzigama: Kumenya hakiri kare ibibazo bito (urugero, gazi yamenetse) birinda gusanwa bihenze.
- Kwubahiriza ibyuka bihumanya ikirere: Menya neza ko ikinyabiziga cyawe cyatsinze igenzura ryumwotsi.
- Ingaruka ku bidukikije: Kugabanya umwanda wa hydrocarubone uva mumyuka ya lisansi.
Impanuro: Niba urumuri rwa moteri rugaragara, banza ugenzure gaze ya gaze. Niba ukomeje kandi urumuri rukomeza, koresha scaneri ya OBD2 kugirango ugarure kode yo gukemura ibibazo.
Aya makuru aha imbaraga ba nyirubwite gukemura ibibazo byoroheje, kwirinda ubugenzuzi bwatsinzwe, no gukomeza imikorere yimodoka no kubahiriza ibidukikije.
