Ana kiransa TDC ko crankshaft firikwensin (wanda yake kusa da injin tashi sama), yana sanar da ECU game da yanayin injin don sanin lokacin (da nawa) man fetur ya buƙaci allura. Saboda haka, a lokacin da raya da dama cylinders, shi wajibi ne don sarrafa injectors domin su yi aiki a daidai lokacin.

Ka'idar da aiki

Ko da wane nau'in firikwensin TDC / crankshaft (inductive ko tasirin Hall), aikin ya kasance fiye ko žasa iri ɗaya. Manufar ita ce a yi alama a kan ƙwanƙwasa na injin don gaya wa kwamfutar matsayin duk pistons ɗin da ke cikin injin. Duk lokacin da firikwensin ya gano alamar tag, ana aika bayanan zuwa kwamfutar, wanda hakan zai sa allurar ta yi aiki yadda ya kamata.

Kowane hakori da ke wucewa a gaban firikwensin zai haifar da ƙaramin wutar lantarki (ana ƙara maye gurbin na'urori masu auna firikwensin da nau'ikan tasirin Hall). Godiya ga wannan, kwamfutar za ta iya ƙidaya adadin haƙoran da ta ketare don haka ta bi tsarin motsin motar. Bayan ƙara wannan bayanin zuwa alamar, ya san gudu da matsayi na duk pistons. Misali, a cikin hoton da ke sama, zai san inda TDC na cylinders 1 da 4 yake, tunda an riga an tsara shi don zama hakora 14 bayan alamar. Ainihin, kalkuleta yana hasashen komai, yana dogara da ƴan bayanan da aka tanadar masa. Koyaya, lokacin farawa, na'urorin lantarki zasu buƙaci firikwensin camshaft don sanin ko TDC na piston yana matsawa ko shayewa ... A ƙarshe, lura cewa darajan ba lallai ba ne ƴan haƙora ba, wani lokaci ana samun shi akan diski na flywheel. tare da firikwensin da aka makala a bayansa (akan toshe injin).

Sannan ana amfani da ka'idar electromagnetism: injin tashi na karfe tare da hakora (yana da hakora da aka sadaukar don farawa) yana shafar magnetism na firikwensin, sannan aika bugun jini zuwa kwamfutar (ga kowane haƙoran haƙora). Da zaran bambance-bambancen da ke tsakanin bugun jini biyu ya girma, kwamfutar ta san cewa tana kan matakin alamar (wurin da bacewar hakora).

Ga ainihin lankwasa. Shuɗi shine TDC / crankshaft firikwensin kuma ja shine firikwensin matsayi na camshaft.

Idan da katako ne (misali ...), ba zai yi aiki ba, saboda wannan abu ba zai iya rinjayar filin lantarki ba.
