Inzwa yokucindezela kwe-air inlet 274-6720 yekati 320D

Inzwa yokucindezela kokuthatha ithola ukucindezela okuphelele kwe-multifold intake ngemuva kwe-throttle. Ibona ukuguqulwa komfutho ophelele ku-manifold ngokwejubane nomthwalo wenjini, bese iyiguqulela kugesi wesignali bese iyithumela kuyunithi yokulawula injini (ECU). I-ECU ilawula ubuningi bomjovo kaphethiloli oyisisekelo ngokuya ngevolthi yesiginali.

isimiso sokusebenza

Kunezinhlobo eziningi zezinzwa zokucindezela kokuthatha, njenge-varistor ne-capacitor. Ngenxa yezinzuzo zesikhathi sokuphendula ngokushesha, ukunemba okuphezulu kokutholwa, usayizi omncane nokufakwa okuguquguqukayo, i-varistor isetshenziswa kabanzi ohlelweni lomjovo wohlobo lwe-D.

Umdwebo 1 ubonisa ukuxhumana phakathi kwenzwa yokucindezela kokuthatha i-piezoresistive kanye nekhompyutha. Umfanekiso wesi-2 umgomo wokusebenza we-piezoresistive intake pressure sensor, kanye no-R emkhiwaneni. I-1 yi-strain resistors engu-R1, u-R2, u-R3 no-R4 kufig. 2, ezakha ibhuloho lika-Whiston futhi zihlanganiswe ne-silicon diaphragm. I-silicon diaphragm ingakhubazeka ngaphansi kwesenzo sokucindezela okuphelele ku-manifold, okubangela ukuguqulwa kwenani lokumelana le-resistor strain R. Ukuphakama kokucindezela okuphelele ku-manifold, kukhulu ukuguqulwa kwe-silicon diaphragm, futhi ngaleyo ndlela. ushintsho olukhulu lwenani lokumelana le-resistor R.. Okusho ukuthi, ukuguqulwa kwemishini ye-silicon diaphragm iguqulwa ibe isignali kagesi, ekhuliswa yisekethe ehlanganisiwe nokuphuma ku-ECU.

Inzwa Yokucindezela Okuphelele Okuningi (MAP). Ixhuma i-multifold intake tube ne-vacuum tube, futhi ngesivinini esihlukile senjini, izwa ushintsho lwe-vacuum endaweni eningi yokuthatha, bese iyiguqulela isignali kagesi kusukela ekushintsheni kokumelana kwangaphakathi kwenzwa ukuze i-ECU ilungise. ubuningi bomjovo kaphethiloli kanye ne-engeli yesikhathi yokubasa.

Enjinini ye-EFI, inzwa yokucindezela kokuthatha isetshenziselwa ukuthola umthamo womoya owuthathayo, obizwa nge-D-type injection system (uhlobo lwe-velocity density). Inzwa yokucindezela komoya oyithathayo ithola umthamo womoya owuthathayo ngokungaqondile esikhundleni sokuqondile njengenzwa yokugeleza komoya, futhi iphinde ithintwa izici eziningi, ngakho-ke kunomehluko omkhulu phakathi kokutholwa nokugcinwa kwenzwa yokugeleza komoya oyithathayo, kanye namaphutha abangelwa yiyo futhi. babe nezici zayo.
