Menene aikin firikwensin camshaft na mota
Firikwensin matsayi na Camshaft yana taka muhimmiyar rawa a cikin injin mota, babban aikin shine tattara siginar matsayi na camshaft da shigar da shi zuwa sashin sarrafa lantarki (ECU) don tantance lokacin kunnawa da lokacin allurar mai. Ta hanyar gano yanayin juyawa na camshaft, firikwensin yana ƙayyade lokacin buɗewa da rufewa na bawul, don haka samun daidaitaccen sarrafa injin. "
Ka'idar aiki na firikwensin matsayi na camshaft ya dogara ne akan induction electromagnetic ko fasahar induction photoelectric. Lokacin da camshaft ya juya, firikwensin yana gano wani karo ko daraja a cikin camshaft kuma yana haifar da siginar lantarki daidai. Bayan karɓar waɗannan sigina, ECU tana ƙayyade lokacin kunnawa da lokacin allurar mai ta hanyar ƙididdigewa da sarrafawa, don samun ingantaccen sarrafa injin. "
Daidaituwa da amincin na'urorin firikwensin matsayi na camshaft suna da mahimmanci ga aikin injin da tattalin arzikin mai. Idan firikwensin ya gaza, zai iya haifar da kunnawa mara kyau, raguwar tattalin arzikin mai, da yuwuwar ma injin da ba ya aiki yadda ya kamata. Sabili da haka, dubawa na yau da kullum da kuma kula da firikwensin matsayi na camshaft yana da matukar muhimmanci.
camshaft firikwensin wani muhimmin sashi ne na mota, galibi ana amfani dashi don gano matsayin camshaft da sauri, don tabbatar da aikin injin na yau da kullun. Sensor Camshaft, wanda kuma aka sani da Camshaft Matsayi Sensor (CPS) ko Sensor Identification Silinda (CIS), ainihin aikinsa shine tattara siginonin matsayi na camshaft ɗin bawul. Ana ciyar da waɗannan sigina a cikin Sashin sarrafa lantarki (ECU). Daga waɗannan sigina, ECU na iya gano matsawa TDC na Silinda 1 don sarrafa allurar man fetur na jeri, sarrafa lokacin ƙonewa da sarrafa lalata.
