Izingxenye zezimoto ze-Dongfeng Cummins Ukudla Pressure Inzwa 4921322

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 kwenzwa yokucindezela komoya komoya kuthonya ukuthathwa kwevolumu yomoya ngokungaqondile esikhundleni sokuthi ngqo inzwa yokugeleza komoya. Ngasikhathi sinye, kuthintwa futhi ngezinto eziningi, ngakho-ke kunomehluko omkhulu phakathi kokutholwa nokunakekelwa kokudla kwenzwa yokugeleza komoya, kanye namaphutha abangelwa nakho kube nokuba nakho.

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.

Isakhiwo sangaphakathi

Inzwa yengcindezi isebenzisa i-chip yengcindezi yokulinganisa ingcindezi, futhi i-chip yengcindezelo ihlanganisa ibhuloho le-wheatstone ku-silicon diaphragm edonswa yingcindezi. I-chip yengcindezi inzwa yengculazi yengculazi, futhi bonke abakhiqizi abakhulu bezinzwa zengcindezi banezingcindezi zabo, ezinye zazo ezikhiqizwa ngokungemthetho, kanti enye ikhiqizwa ngokuqondile ama-chips akhethekile avela kubakhiqizi be-chip abasebenza ngqo. Ngokuvamile, ama-chip akhiqizwa ngokuqondile abakhiqizi bezinzwa noma abenziwe ngezifiso ama-ASC chips asetshenziswa kuphela kwimikhiqizo yawo. Lawa ma-chip ahlanganiswe kakhulu, futhi i-chip yengcindezi, umjikelezo we-amplifier, i-chip yesiginali ye-chip, i-chip yokuvikela i-EMC, i-ROM yokulinganisa ukulinganisa ijika lokuphuma le-sensor konke kuhlanganiswe kwi-chip eyodwa. Inzwa yonke iyi-chip, futhi i-chip ixhumeke nge-PIN PIN yesixhumi ngokuhola.
