I-AIR NOKUFAKAZA ISIVIVINYO SESTOR (Manifoldabsolutepressor), lapha kubizwa ngokuthi yimephu. Ixhumeke ekungeneni okuningi nge-tube ye-vacuum. Ngemithwalo ye-enjini ehlukene ye-enjini, ingabona ushintsho lwe-vacuum ekungeneni okuningi, bese uguqula ushintsho lokumelana ngaphakathi kwenzwa ye-sensor ibe yisiginali ye-voltage, engasetshenziswa i-angle yokujova kanye ne-angle yesikhathi sokulahla.
Enjini ye-EFI, inzwa yokucindezela yokudla isetshenziselwa ukuthola ivolumu yokuthambisa, okubizwa ngokuthi uhlelo lokujova kwe-D (velocity density yohlobo). Inzwa yokucindezela yokudla ibona ivolumu yokuthambisa ayitholakali ngqo njenge-in sensor yokugeleza, kepha itholwe ngokungaqondile. Ngasikhathi sinye, kuthintwa futhi ngezinto eziningi, ngakho-ke kunezindawo eziningi ezahlukahlukene ekutholweni nasekulungiseni kusuka enzwa yokugeleza kokudla, nephutha elakhiwe libuye libe nokwenziwa kwalo
Inzwa yengcindezi yokuthambisa ithola ingcindezi ngokuphelele yokudla okuningana ngemuva kwe-throttle. Ithola ushintsho lwengcindezi ephelele ku-manifold ngokuya ngejubane le-Injini, bese uyiguqula ibe yi-voltal voltage bese iyithumela kwiyunithi yokulawula injini (ECU). I-ECU ilawula inani eliyisisekelo likaphethiloli ngokuya ngosayizi we-Signal Voltage.
Kunezinhlobo eziningi zezinzwa ze-Inlet Pressure, njengohlobo lwe-varistor nohlobo lwe-capacitive. I-Varitor isetshenziswa kabanzi ngohlelo lokujova kwe-D ngenxa yezinzuzo zayo njengesikhathi sokuphendula esisheshayo, ukunemba okutholwayo okuphezulu, usayizi omncane nokufakwa okuguqukayo.
Umdwebo we-1 ukhombisa ukuxhumana phakathi kwe-Varistor yokuthakwa kwengcindezi yenzwa nekhompyutha. Fig. 2 ikhombisa umgomo osebenzayo wohlobo lwe-varistor uhlobo lwengcindezi yenzwa, futhi r ku-Fig. 1 ingu-REAin Working R1, R2, R3 no-R4 ku-Fig. 2, okwakha ibhuloho le-wheatstone futhi lihlanganiswe kanye ne-silicon diaphragm. I-Silicon Diaphragm ingakhubazeka ngaphansi kwengcindezi ephelele ku-mainlold, okuphumela ekushintsheni kwenani lokumelana nobuningi be-silicon diaphragm, izinguquko zemishini ye-silicon diaphragm ziguqulwa zibe amasiginali kagesi, akhishwe yi- umjikelezo ohlanganisiwe bese ukhipha i-ECU
