Aikin crankshaft na mota
Rangwamen injin mota muhimmin sashi ne na injin, wanda galibi yana aiki don canza motsi mai layi na pistons zuwa motsi mai juyawa da ƙarfin fitarwa don tuƙa tsarin watsawa na abin hawa da sauran kayan haɗi.
Canza wutar lantarki: Crankshaft yana karɓar ƙarfin motsi na layi daga pistons ta hanyar haɗa sandunan kuma yana mayar da shi zuwa ƙarfin juyawa, yana tuƙa ƙafafun tashi da tsarin watsawa, yana ba motar damar motsawa.
Kayan Tuki: Juyawar crankshaft ɗin kuma tana tuƙa na'urori masu taimako kamar janareto, famfunan ruwa, da fanka ta hanyar bel ko sarƙoƙi, wanda ke tabbatar da aikin injin yadda ya kamata.
Jure wa lodi da daidaito: Crankshaft yana ɗauke da lodi masu rikitarwa kamar matsin iskar gas da ƙarfin inertial, kuma an tsara shi da daidaita nauyi don rage girgiza da kuma tabbatar da aikin injin cikin santsi.
Crankshaft yana ɗaya daga cikin muhimman abubuwan da ke cikin injin, wanda ke da alhakin canza motsin pistons zuwa motsi na juyawa da ƙarfin fitarwa. Da zarar ya gaza, zai yi tasiri sosai ga aikin injin na yau da kullun. A cewar bayanan jama'a na baya-bayan nan (kamar yadda aka bayyana a watan Maris na 2026), manyan abubuwan da ke bayyana, abubuwan da ke haifar da gazawar crankshaft sune kamar haka:
Alamomin gama gari na gazawar crankshaft
Matsalar farawa: Lalacewar bearings na crankshaft ko lalacewar littafin yana haifar da matsala wajen kunna injin.
Rage ƙarfin lantarki: Rage ƙarfin lantarki na crankshaft ya kasa isar da ƙarfin juyi yadda ya kamata, wanda ke haifar da saurin gudu a hankali da kuma raguwar fitowar wutar lantarki sosai.
Hayaniya mara kyau: Sautin gogayya na ƙarfe kamar "buzzing" ko "clicking" yana faruwa yayin aikin injin, musamman ma lokacin farawa da haɓaka.
Girgizar abin hawa: Girgizar crankshaft tana kawo cikas ga daidaiton injin, tana haifar da girgiza a fili a lokacin aiki ko lokacin tuki.
Ƙara yawan amfani da mai: Rage yawan amfani da mai da kuma ƙaruwar amfani da mai.
Yawan zafi a injin: Rage matsin lamba na mai da kuma tasirin tsarin sanyaya, wanda ke haifar da hauhawar zafin jiki mara kyau.
Kashe injin ba zato ba tsammani: A cikin mawuyacin hali, injin na iya kashewa ba zato ba tsammani yayin tuki.
Fitilar lalacewar injin tana haskakawa: ECU tana gano wani abu mai ban mamaki (kamar asarar siginar matsayi na crankshaft) kuma tana kunna hasken matsalar injin.
Lura: Wasu alamun (kamar hasken injin da ke haskakawa, wahalar farawa) na iya faruwa ne sakamakon gazawar firikwensin matsayi na crankshaft, wanda matsalar siginar lantarki ce maimakon lalacewa ga crankshaft ɗin kanta.
Ana buƙatar ganewar asali ta ƙwararru don bambancewa.
Nau'ikan kurakurai da dalilai da aka saba
Lalacewar mujallu: Rashin isasshen mai ko lalacewarsa, kasancewar ƙazanta, ko rashin isasshen sarari tsakanin mujallun da crankshaft.
Karce/ƙarce-ƙarce a cikin mujallu: Rashin tsaftar haɗa abubuwa, rashin canza mai akan lokaci, ko kuma gazawar matatar iska, wanda ke barin ƙazanta ta shiga.
Ƙonewar Jarida: Yawanci yakan faru ne sakamakon haɗarin "walda", tare da saman shuɗi.
Fashewa ko karyewa:
Yawanci yana faruwa ne a mahadar hannun crank da kuma mujallar, ko kuma kusa da mashigar mai na mujallar connecting sandar;
Dalilan sun haɗa da lahani na kayan aiki, gajiya, yawan lodi, gazawar na'urar ɗaukar girgiza, da kuma lalacewar daidaiton aiki yayin gyaran walda.
Nakasar crankshaft:
Nauyin da ke tashi da sauri, birki ba zato ba tsammani, ko kuma haɗuwa ba daidai ba.
Kamawar crankshaft: Rashin tsarin man shafawa, kulle busasshen gogayya na bearings masu zamiya.
Shawarwari don mayar da martani da rigakafi
Tsayar da abin hawa nan take don a duba shi: Da zarar alamun da ke sama sun bayyana, musamman tare da hayaniya mara kyau, girgiza, ko rashin iya tashi, a daina amfani da abin hawa don guje wa ƙarin lalacewa.
Ganewar ƙwararru:
Karanta lambobin kuskuren ta amfani da na'urar OBD don tantance ko matsalar firikwensin ce (kamar P0335 da ke da alaƙa da lambobin firikwensin matsayi na crankshaft);
Idan ana zargin lalacewar da aka samu a kan crankshaft ɗin, a sake buɗe shi domin a duba lalacewarsa, tsagewar da kuma yanayin lanƙwasawa.
Ka'idojin kulawa:
Ana iya gyara ƙananan lalacewa ta hanyar niƙa;
Fashewa, karyewa, da kuma mummunan nakasu yawanci suna buƙatar maye gurbinsu;
Bayan gyarawa, yi gyaran daidaito mai ƙarfi kuma tabbatar da cewa an sanya ƙafafun daidaitacce.
Matakan rigakafi:
A riƙa maye gurbinsa da mai akai-akai sannan a tace shi da takamaiman bayani da ya dace;
Guji ɗaukar nauyin kaya na dogon lokaci da kuma aiki da sauri fiye da kima;
Kula da dumama injinan sanyi kafin lokaci, a guji hanzarta hanzarin kwatsam;
A bi ƙa'idodin da aka tanada don haɗawa yayin kulawa don tabbatar da tsafta da tsabta.
Idan kana son ƙarin bayani, ci gaba da karanta sauran labaran da ke wannan shafin!
Don Allah a kira mu idan kuna buƙatar irin waɗannan kayayyaki.
