Volkswagen/Audi EA888 m'badwo wachiwiri wolekanitsa mafuta-gasi (valavu ya zinyalala)
Galimoto yapachiyambi imagawidwa m'magulu awiri amphamvu ndi otsika
Mukasintha, ingofananiza nambala yagalimoto yoyambirira!
● Malamulo a chilengedwe amafuna kuti mphamvu ya crankcase ikhale yoipa, ndiko kuti, kuthamanga kwa crankcase kuyenera kukhala kotsika kusiyana ndi mpweya wabwino wa mumlengalenga kuti mpweya wa crankcase usatuluke mumlengalenga ndikuyambitsa kuipitsa;
● Kusiyanitsa kokha pakati pa mphamvu zamphamvu ndi zotsika ndizofunika kupanikizika koipa, komwe kumatsimikiziridwa ndi kasupe wothamanga mu valve yotulutsa mpweya;
● Mbar ndi mawu ofanana ndi ma millibars, omwe ndi gawo la kuthamanga kwa mpweya. Sikweya centimita imodzi imagonjetsedwa ndi 1 kilogalamu ya kuthamanga kwa mumlengalenga, komwe kumatchedwa "1 bar". Chikwi chimodzi cha "bar" chimatchedwa "millibar". Kuthamanga kwa mumlengalenga kumodzi ndi kofanana ndi 1013 millibars, kotero mamilibari 100 ali pafupifupi ofanana ndi gawo limodzi mwa magawo khumi a mphamvu ya mumlengalenga;
1. Mtundu wamphamvu kwambiri
OE nambala:
06H103495AF=AE=AK=K
Kupanikizika koyipa: -100Mbar (millibar)
Kuthamanga koyipa kokhazikika pa liwiro lopanda ntchito: -115 mpaka -90 mbar
2. Mtundu wamagetsi otsika
OE nambala:
06H103495AB=AC=AD=AH=AJ=B=H=E
Kupanikizika koyipa: -25Mbar (millibar)
Kuthamanga kwabwino kwabwino pa liwiro lopanda ntchito: -28.5 mpaka -18.5 mbar
● Ngati vacuum ili yocheperapo, kutayikira kwa crankcase kapena kuphulika kwamphamvu kuyenera kuyang'aniridwa;
● Ngati vacuum yakwera kwambiri, diaphragm ndi kasupe mu valve yotulutsa mpweya ziyenera kufufuzidwa, kapena valve yotulutsa mpweya iyenera kusinthidwa mwachindunji;
★ Zolakwika zodziwika bwino za EA888 valavu yotulutsa injini yachiwiri
1. The pressure regulating valve diaphragm is perforated
Chidutswa choyambirira cha rabara chakuda chinali chosavuta kukalamba komanso kuphulika. Tsopano yasinthidwa kukhala diaphragm yofiyira yokhala ndi ma mesh olimbikitsidwa, omwe samadwala kawirikawiri;
2. Bowo lotayira mafuta latsekedwa, zomwe zimapangitsa mafuta olekanitsidwa kuti asabwererenso bwino
3. Gasket yosindikiza ikukalamba, zomwe zimapangitsa kuti mafuta azituluka mozungulira
★ Zokhudza kuwotcha mafuta a injini
Zomwe zimatchedwa "kuwotcha mafuta" kwenikweni ndi dzina lodziwika bwino la "kugwiritsa ntchito mafuta mopitilira muyeso".
Zifukwa zazikulu zowotcha mafuta a EA888:
1. Vavu mafuta chisindikizo kukalamba ndi kuwonongeka
Valve mafuta chisindikizo ali ndi ntchito ziwiri:
Chimodzi ndi kuteteza kusakaniza mu chipinda choyaka moto kapena mpweya wotuluka pambuyo poyaka kuti zisatayike;
Zina ndikuletsa mafuta a injini kuti asalowe m'chipinda choyaka ndikuchita nawo kuyaka;
Choncho, pamene chisindikizo cha mafuta a valve chili ndi chisindikizo chosauka, chidzachititsa kuti mphamvu ya silinda igwere komanso vuto la "mafuta oyaka moto".
2. Kuchepetsa kusindikiza kwa mphete za pistoni
Pistoni nthawi zambiri imakhala ndi mphete ziwiri za mpweya ndi mphete imodzi yamafuta.
Mphete ya mpweya imagwiritsidwa ntchito kutsimikizira chisindikizo pakati pa silinda ndi pisitoni, pomwe mphete yamafuta imagwiritsidwa ntchito kufalitsa ndikukwapula mafuta. Pistoni ikakwera m'mwamba, mafuta amapaka pakhoma la silinda, ndipo pisitoni ikatsika pansi, mafutawo amachotsedwa.
Pamene mphete ya pistoni imavala, ntchito yake yosindikiza imachepa pang'onopang'ono mpaka mafuta alowe m'chipinda choyatsira moto kuchokera pakati pa mphete ya pistoni ndi khoma la silinda kuti atenge nawo mbali kuyaka. Ili ndilo tanthauzo lenileni la "mafuta oyaka".
3. Kuvala kwa Cylinder eccentric kapena kuvala kwambiri
Mphete ya pisitoni (mphete yamafuta) imakhala yosalumikizana bwino ndi khoma la silinda, ndipo mafuta a injini amakwera m'chipinda choyaka ndikuwotchedwa.
4. Gwiritsani ntchito mafuta a injini otsika ndi fyuluta yamafuta
Mafuta a injini otsika sangapereke chitetezo choyenera cha kugundana, chifukwa chake amafulumizitsa kuvala kwa zigawo za injini. Izi zikuphatikiza mphete za pistoni ndi makoma a silinda omwe tafotokoza pamwambapa. Kuvala kwachilendo kumathandizira kukalamba kwa injini ndikupangitsa "kuwotcha mafuta" nthawi isanakwane.
5. Kuthamanga kwa mafuta osadziwika bwino
Mafuta akakwera kwambiri, zimapangitsa kuti chisindikizo cha injini chizichulukira, mafuta amatha kutuluka kapena kulowa m'chipinda choyaka ndikuyaka, zomwe zimapangitsa kuti mafuta azigwiritsidwa ntchito molakwika.
Zifukwa za kupanikizika kwambiri kwamafuta ndi monga: fyuluta yamafuta kapena kutsekeka kwa njira yamafuta, kupanikizika kwambiri kwa kutseguka kwa valve yoletsa kutsekeka, kukhuthala kwamafuta kwambiri, ndi zina zambiri.
4. Cholekanitsa mafuta-gasi (valavu yotulutsa mpweya) sichimalekanitsidwa kwathunthu
Pamene phokoso la crankcase ndi lalikulu kwambiri kapena valavu yotulutsa mpweya yokha ikulephera, kusakaniza kwa mafuta-gasi sikungathe kupatukana kwathunthu, kuchititsa kuti mbali ina ya mafuta osasiyanitsidwa abweretsedwe mu chipinda choyaka moto ndikuwotchedwa.
Choncho, kusintha valavu yotulutsa mpweya sikungathe kuthetsa vuto la mafuta oyaka.
Galimoto ikawotcha mafuta, mutha kuyang'ana kaye vacuum ya crankcase komanso ngati valavu yotulutsa yokha ndiyolakwika. Ngati zimayambitsidwa ndi valavu yotulutsa mpweya, mutha kusintha valavu yatsopano yotulutsa mpweya. Ngati zili chifukwa chazifukwa zina, muyenera kusintha zida zina zofananira.
