Menene aikin firikwensin camshaft na mota
Na'urar firikwensin matsayi na Camshaft tana taka muhimmiyar rawa a cikin injin mota, babban aikinta shine tattara siginar matsayin camshaft da shigar da ita zuwa sashin sarrafa lantarki (ECU) don tantance lokacin kunnawa da lokacin allurar mai. Ta hanyar gano matsayin juyawa na camshaft, na'urar firikwensin tana tantance lokacin buɗewa da rufewa na bawul ɗin, don haka cimma daidaitaccen iko na injin.
Ka'idar aiki na na'urar firikwensin matsayi na camshaft ta dogara ne akan fasahar induction na lantarki ko fasahar photoelectric induction. Lokacin da camshaft ke juyawa, na'urar firikwensin tana gano wani ƙulli ko ƙulli a cikin camshaft kuma tana samar da siginar lantarki mai dacewa. Bayan karɓar waɗannan sigina, ECU tana ƙayyade lokacin kunna wuta da lokacin allurar mai ta hanyar lissafi da sarrafawa, don cimma ingantaccen iko na injin.
Daidaito da amincin na'urorin auna matsayi na camshaft suna da matuƙar muhimmanci ga aikin injin da kuma tattalin arzikin mai. Idan na'urar auna ta gaza, zai iya haifar da ƙonewa mara daidai, raguwar ƙarfin mai, da kuma yiwuwar ma injin da ba ya aiki yadda ya kamata. Saboda haka, dubawa akai-akai da kula da na'urar auna matsayi na camshaft yana da matuƙar muhimmanci.
Na'urar firikwensin camshaft muhimmin sashi ne na mota, wanda galibi ake amfani da shi don gano matsayin camshaft da saurinsa, don tabbatar da aikin injin na yau da kullun. Na'urar firikwensin Camshaft, wanda kuma aka sani da Na'urar Firikwensin Matsayin Camshaft (CPS) ko Na'urar Firikwensin Shaidar Silinda (CIS), babban aikinsa shine tattara siginar matsayi na camshaft ɗin bawul. Ana shigar da waɗannan siginar cikin Na'urar Kula da Lantarki (ECU). Daga waɗannan siginar, ECU tana iya gano TDC mai matsewa na silinda 1 don sarrafa allurar mai a jere, sarrafa lokacin ƙonewa da sarrafa fashewa .
