I-Air Inlet Pressure Sensor 274-6720 yekati 320D

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 lokulinganisa likaphethiloli ngokuya nge-Signal Voltage.

Umgomo Wokusebenza

Kunezinhlobo eziningi zezinzwa zokuphambukisa zokudla, njenge-varistor ne-capacitor. Ngenxa yezinzuzo zesikhathi sokuphendula esisheshayo, ukunemba okutholwayo okuphezulu, usayizi omncane nokufakwa okuguqukayo, i-varitor isetshenziswa kabanzi kuhlelo lokujova kwe-D-Tidter.

Fig. 1 ikhombisa ukuxhumana phakathi kwe-piezoresoresistive yokungcwana inzwa nekhompyutha. Umdwebo 2 ungumgomo osebenzayo we-PieZoresuresstive Ukungena Kwesifungo Inzwa, futhi r ku-Fig. 1 ingu-REAin Working R1, R2, R3 no-R4 ku-Fig. 2, okwakha ibhuloho le-Whistson futhi liboshelwe ku-silicon diaphragm. I-silicon diaphragm ingakhubazeka ngaphansi kwesenzo sokucindezelwa ngokuphelele kwi-main, okubangela ukuguqulwa kwenani lokumelana ne-silicon diaphragm likhuphuka libe yisiginali kagesi, okuyinto kukhuliswe yi-Contentimed Circuit kanye nokukhipha ku-Ecu.

I-Manifold ngokuphelele Pressure Sensor (Imephu). Ixhumanisa manifold yokudla nge-vacuum tube, futhi nomthwalo wejubane le-enjini ehlukile, kuzwakala ushintsho lwe-vacuum ku-mantifold mantifold, bese uliguqula libe yisiginali ye-voltage kusuka ekushintsheni kwangaphakathi kwe-ECU ukulungisa inani lokuphikisana nokwehla kwamandla.

Ku-EFI Injini, inzwa yokucindezela yokudla isetshenziselwa ukuthola ukuthathwa komoya wokudla, okubizwa ngokuthi uhlelo lokujova kwe-D-Tidy (velocity density). Ukuthathwa kwengcindezi yomoya yomoya kuthonya ukuthathwa kwevolumu yomoya ngokungaqondile esikhundleni sokuthi ngqo njengenzwa yokugeleza komoya, ngakho-ke kuthinteka ezintweni eziningi, ngakho-ke kunomehluko omkhulu phakathi kokutholwa nokunakekelwa kokutholwa kokutholwa kwenzwa yokungena komoya, kanye nokunakekelwa kokudla okubangelwa nakho.
