Inzwa yoxinzelelo lwe-air inlet 274-6720 yekati 320D

Inzwa yoxinzelelo lwe-intake ibona uxinzelelo olupheleleyo lwe-manifold intake emva kwe-throttle. Ibona utshintsho loxinzelelo olupheleleyo kwi-manifold ngokwesantya kunye nomthwalo we-injini, emva koko iyiguqule ibe ngumbane wesignali kwaye iyithumele kwiyunithi yokulawula injini (ECU). I-ECU ilawula ubungakanani benaliti yamafutha esisiseko ngokombane wesignali.

umgaqo wokusebenza

Kukho iintlobo ezininzi zeenzwa zoxinzelelo lokuthatha, njenge-varistor kunye ne-capacitor. Ngenxa yeenzuzo zexesha lokuphendula ngokukhawuleza, ukuchaneka okuphezulu kokufumanisa, ubungakanani obuncinci kunye nofakelo oluguquguqukayo, i-varistor isetyenziswe ngokubanzi kwi-D-type injection system.

Umzobo we-1 ubonisa uxhulumaniso phakathi kwe-piezoresistive intake pressure sensor kunye nekhompyutheni. Umzobo we-2 ngumgaqo osebenzayo we-piezoresistive intake pressure sensor, kunye ne-R kumkhiwane. I-1 yi-strain resistors i-R1, i-R2, i-R3 kunye ne-R4 kwifig. 2, eyenza ibhulorho yaseWhiston kwaye idityaniswe kwi-silicon diaphragm. I-silicon diaphragm inokukhubazeka phantsi kwesenzo soxinzelelo olupheleleyo kwizinto ezininzi, ezibangela ukuba utshintsho lwexabiso lokumelana noxinzelelo lwe-R. Utshintsho olukhulu lwexabiso lokumelana ne-resistor R .. Oko kukuthi, ukuguqulwa komatshini we-silicon diaphragm iguqulwa ibe ngumqondiso wombane, okhuliswa yisekethe edibeneyo kunye nemveliso kwi-ECU.

ISensom yoxinzelelo olupheleleyo (MAP). Idibanisa i-intake manifold kunye netyhubhu yokucoca, kunye nomthwalo ohlukeneyo wesantya se-injini, iyaluva utshintsho lwe-vacuum kwindawo yokuthatha, kwaye emva koko iyiguqule ibe ngumqondiso wombane ukusuka kutshintsho lokumelana kwangaphakathi kwe-sensor ye-ECU ukulungisa. ubungakanani benaliti yamafutha kunye ne-engile yexesha lokutshisa.

Kwi-injini ye-EFI, i-sensor yoxinzelelo lwe-intake isetyenziselwa ukufumanisa umthamo womoya wokungenisa, obizwa ngokuba yi-D-type injection system (uhlobo lwe-velocity density). Inzwa yoxinzelelo lomoya yokuthatha ibona umthamo womoya wokuthatha ngokungathanga ngqo endaweni yokuba ngqo njengenzwa yokungena komoya, kwaye ikwachatshazelwa zizinto ezininzi, ke kukho umahluko omkhulu phakathi kokufunyanwa kunye nokugcinwa kwenzwa yokungena komoya, kunye neempazamo ezibangelwa yiyo kwakhona. zineenkcukacha zayo.
