Ayyukan firikwensin matsa lamba na mota
Babban ayyuka na firikwensin motsin iska na mota sun haɗa da abubuwa masu zuwa:
Samar da siginar lodin injin: Na'urar firikwensin abun ciki yana ba da siginar nauyin injin zuwa ECU (Sashin sarrafa injin) ta hanyar auna canjin matsa lamba a cikin nau'ikan abubuwan sha. Waɗannan sigina suna taimaka wa ECU daidai sarrafa faɗin bugun bugun allura da buɗewa don haɓaka aikin injin da tattalin arzikin mai.
Sarrafa allurar man fetur da lokacin kunnawa: Na'urori masu auna firikwensin suna canza canjin matsa lamba a cikin nau'ikan abun ciki zuwa siginar lantarki don ECU don gyara allurar man fetur da kusurwar lokacin kunnawa. Lokacin da nauyin injin ya karu, matsa lamba a cikin nau'in abun ciki yana raguwa, siginar fitarwa na firikwensin yana ƙaruwa, kuma ECU yana ƙara adadin allurar mai kuma yana jinkirta kusurwar gaba. In ba haka ba, allurar mai za ta ragu kuma za a ci gaba da kunna wuta.
Daidaita lokacin buɗewa bawul ɗin buɗaɗɗen lokacin buɗewa da allurar man fetur: A cikin injin da ke da tsarin sarrafa bawul ɗin lantarki, firikwensin mai ɗaukar nauyi yana gano canjin matsa lamba a cikin bututun ci kuma daidai ƙididdige ƙarar iska a cikin kowane Silinda don daidaita lokacin buɗewar bawul ɗin ci da ƙarar allurar man fetur. Wannan yana taimakawa wajen haɓaka inganci da ƙarfin injin.
Kare inji : Firikwensin matsa lamba na iya kuma gano yanayin aiki mara kyau na injin, kamar canjin matsa lamba mara kyau, da aika sigina zuwa tsarin sarrafawa don kare injin. Wannan yana taimakawa hana lalacewar injin saboda yin fiye da kima ko wasu batutuwa.
Ƙa'idar aiki : Ana haɗa firikwensin matsa lamba yawanci zuwa nau'in abun sha ta cikin bututun injin kuma yana jin canjin injin a cikin nau'in abin sha. Yayin da saurin injin da kaya ke canzawa, matsa lamba a cikin nau'in abin sha zai canza, kuma juriya a cikin firikwensin shima zai canza daidai da haka, don haka fitar da siginar wutar lantarki. Ana karɓar wannan siginar ta ECU kuma ana amfani da ita don daidaita allurar mai da lokacin kunnawa.
Tasirin kuskure : Idan firikwensin matsa lamba ya lalace, zai iya haifar da rashin tsayawar gudu, rauni mai rauni, wahalar farawa, ƙara yawan mai da sauran matsalolin abin hawa. A lokaci guda, za a kunna fitilar kuskuren injin, kuma za a adana lambar kuskuren daidai.
Don haka, dubawa na yau da kullun da kula da firikwensin matsa lamba yana da mahimmanci don tabbatar da aikin al'ada na abin hawa.
Manifold Absolute Pressure Sensor (MAP) wani muhimmin abu ne a cikin injin mota wanda ke lura da sauye-sauyen matsa lamba a cikin nau'ikan abin sha kuma yana canza waɗannan canje-canje zuwa siginar lantarki don ingantaccen sarrafawa ta sashin sarrafa lantarki na injin (ECU). Ana haɗe firikwensin matsa lamba zuwa nau'in abin sha ta cikin bututun injin kuma yana iya jin canjin injin a cikin nau'in abin sha. Tare da saurin injin daban-daban da kaya, juriya a cikin firikwensin zai canza, wanda za a canza shi zuwa siginar lantarki don ECU don gyara adadin allurar mai da lokacin kunnawa.
Ƙa'idar aiki
Ka'idar aiki na firikwensin matsa lamba yana dogara ne akan canjin juriya da canjin matsa lamba ya haifar. Ɗauki nau'in firikwensin matsa lamba na nau'in varistor a matsayin misali, ainihin ɓangaren sa shine diaphragm na silicon wanda aka yi da tasirin piezoresistive na semiconductor. Lokacin da matsa lamba na nau'in abin da ake amfani da shi yana aiki akan diaphragm na silicon, diaphragm zai lalace, yana haifar da canji a ƙimar juriya. Ana canza wannan canjin zuwa siginar lantarki, wanda aka haɓaka kuma aka wuce zuwa ECU. Dangane da ƙarfin siginar da aka karɓa, ECU tana sarrafa ainihin allurar mai don dacewa da buƙatun tuƙi daban-daban.

Akwai nau'ikan firikwensin matsa lamba da yawa, na gama gari sune semiconductor varistor, vacuum bellows da capacitive. Daga cikin su, semiconductor varistor ana amfani dashi sosai a cikin tsarin allura na nau'in D saboda fa'idodinsa na saurin amsawa, babban madaidaici, ƙaramin girman da shigarwa mai sauƙi. Na'urar firikwensin capacitive yana amfani da diaphragm don samar da wani nau'i mai mahimmanci na matsa lamba tare da madaidaicin ƙimar ƙarfin, kuma yana canza canjin matsa lamba zuwa siginar lantarki ta hanyar auna kewaye.
Kulawa da gano kuskure
Gano kuskuren firikwensin matsa lamba yawanci ya haɗa da bincika ko siginar fitarwa yana tsakanin kewayon al'ada. Idan siginar fitarwa na firikwensin ba ta da kyau, aikin injin na iya lalacewa ko rashin kwanciyar hankali. Yayin kulawa, lokaci-lokaci bincika haɗin gwiwa da hatimin firikwensin don tabbatar da cewa yana aiki da kyau.
