Firikwensin matsin lamba.
Firikwensin matsi na iska (ManifoldAbsolutePressureSensor), daga baya ana kiransa MAP. An haɗa shi da nau'in abin sha tare da bututu mai ƙura, kuma tare da nauyin nauyin injin daban-daban, ana haifar da canjin injin a cikin nau'in abin sha, sa'an nan kuma canjin juriya a cikin firikwensin ya canza zuwa siginar lantarki don ECU zuwa gyara adadin allura da kusurwar lokacin kunnawa.
A cikin injin EFI, ana amfani da firikwensin matsa lamba don gano ƙarar abun ciki, wanda ake kira tsarin D-injection (nau'in girman saurin gudu). Na'urar matsa lamba ta gano ƙarar abun ciki ba a gano shi kai tsaye kamar na'urar firikwensin abun ciki, amma yana amfani da ganowa kai tsaye, sannan kuma yana da tasiri da abubuwa da yawa, don haka akwai wurare daban-daban a cikin ganowa da kiyayewa fiye da na'urar motsi, kuma Laifin da aka haifar shima yana da nasa musamman.
Na'urar bugun jini tana gano cikakken matsi na nau'in abin da ake ci a bayan bawul ɗin magudanar ruwa, wanda ke gano cikakken canjin matsa lamba a cikin manifold gwargwadon saurin injin ɗin da lodi, sannan ya canza ƙarfin siginar zuwa sashin sarrafa injin (ECU), kuma ECU tana sarrafa ainihin adadin allurar mai gwargwadon girman ƙarfin siginar.
Firikwensin matsa lamba wani nau'i ne na firikwensin da ake amfani da shi don lura da canjin matsa lamba a cikin tsarin shan injin. Yana taka muhimmiyar rawa a cikin motoci ko wasu kayan aikin ingin konewa na ciki.
