Wadanne irin tasiri zai yi wa motar idan na'urar firikwensin camshaft ta karye?
Na'urar firikwensin camshaft da ta lalace na iya haifar da matsaloli a lokacin kunna injin, girgiza yayin aiki, raguwar wutar lantarki, ƙaruwar yawan mai, kuma yana iya haifar da ƙararrawa ta walƙiya.
Matsalolin Fara Injin da Aiki
Wahala wajen farawa da kunna wuta mai cike da rudani: Bayan na'urar firikwensin ta lalace, ECU ba zai iya tantance matsayin kowace silinda da matakin camshaft daidai ba, wanda ke haifar da lokacin kunna wuta mai cike da rudani, wanda ke nuna yana buƙatar yunƙuri da yawa don farawa, ko ma jinkirin farawa ko rashin iya farawa. A cikin mawuyacin hali, yayin aikin farawa, yana iya samun juyawar crankshaft da abubuwan da ke faruwa na juyawar flashback.
Lalacewar kwanciyar hankali da aiki:
Girgizar da ke faruwa a lokacin da babu aiki: Kamar yadda yake a yanayin rashin nasarar injin, girgizar a bayyane take.
Yawan tsayawar injin yayin tuki: Musamman a yanayin dumama, motar na iya tsayawa ba zato ba tsammani yayin tuki ko cika mai.
Amsar hanzari a hankali: Bayan taka kan mai ƙararrawa, fitowar wutar lantarki ba ta tsayawa, kuma yawanci, saurin injin yana buƙatar wuce 2500 rpm don ingantawa.
Lalacewar Aikin Wutar Lantarki da Tattalin Arzikin Mai
Raguwar da aka samu a yawan wutar lantarki: Saboda ECU ba ta karɓar siginar camshaft daidai ba, lokacin shigar mai da kunna wuta ba za a iya daidaita su da aikin silinda ba, wanda ke haifar da raunin injin, saurin gudu da sauri, da kuma jinkirin amsawa yayin hawa ko wucewa. ECU na wasu samfuran kuma na iya iyakance matsakaicin saurin injin don kare injin.
Ƙara yawan amfani da mai da hayaki: Ikon ECU na allurar mai ba daidai ba ne, yana haifar da allurar mai da yawa ko kuma rashin daidaiton allurar mai, kuma yawan amfani da mai da aka auna na iya ƙaruwa da kashi 15%-30%. A lokaci guda, ƙonewa mara cikakke zai haifar da hayaki baƙi daga bututun hayaki, ƙara warin hayaki, kuma yana iya ƙara nauyin da ke kan na'urar firikwensin iskar oxygen da mai canza mai hanyoyi uku, tare da haɗarin lalacewa a kan aiki na dogon lokaci.
Kariyar Tsarin da Haɗarin Injin da Ke Iya Faru
Kunna yanayin kariyar lahani: Hasken lalacewar injin yana kunne akai-akai (yawanci yana daidai da lambobin lahani kamar P0340), kuma ECU zai shiga yanayin, yana iyakance fitarwar wutar lantarki, kuma yana iya kashe ayyuka kamar lokacin bawul mai canzawa (VVT). A wannan lokacin, abin hawa zai iya tafiya ne kawai a ɗan gajeren lokaci, amma aikin yana da iyaka sosai.
Haɗarin lalacewar injiniyanci mai yiwuwa:
Daidaiton lokacin kunna wuta: Yana iya haifar da fashewar, kuma akan lokaci, zai haifar da lalata silinda, piston, da sauran sassan.
Ƙara yawan lalacewar tsarin bawul: ECU ba zai iya sarrafa matakin bawul daidai ba, wanda hakan na iya ƙara ta'azzara lalacewar kayan aikin injiniya masu alaƙa.
A cikin mawuyacin hali inda na'urar firikwensin crankshaft ta lalace, abin hawa na iya kasa tashi ko tsayawa gaba ɗaya yayin aiki.
