Iyo air inlet pressure sensor 274-6720 yekatsi 320D

Iyo yekutora pressure sensor inoona iyo yakazara kudzvanywa kweiyo manifold yekutora kuseri kwe throttle. Iyo inoona shanduko yeakazara kudzvanywa mune yakawanda zvinoenderana nekumhanya kweinjini uye mutoro, uye yozoishandura kuita chiratidzo chemagetsi uye inotumira kune injini yekudzora unit (ECU). Iyo ECU inodzora iyo yakakosha jekiseni huwandu hunoenderana neiyo chiratidzo voltage.

musimboti wekushanda

Kune akawanda marudzi ekutora kumanikidza masensa, akadai sevaristor uye capacitor. Nekuda kwemabhenefiti ekukurumidza kupindura nguva, yakakwirira yekuona kurongeka, diki saizi uye inochinjika kuisirwa, varistor inoshandiswa zvakanyanya muD-mhando jekiseni system.

Mufananidzo 1 unoratidza kuwirirana pakati pepiezoresistive intake pressure sensor uye kombiyuta. Mufananidzo 2 ndiyo nheyo yekushanda yepiezoresistive intake pressure sensor, uye R mufig. 1 ndiyo inopikisa R1, R2, R3 uye R4 mumuonde. 2, iyo inoumba zambuko reWhiston uye yakasungirirwa kusilicon diaphragm. Iyo silicon diaphragm inogona kuremara pasi pekuita kwekumanikidza kwakazara mune yakawanda, iyo inokonzera shanduko yekupikiswa kukosha kweiyo strain resistor R. Iyo yakakwirira iyo mhedziso yekumanikidza mune yakawanda, iyo yakakura deformation yesilicon diaphragm, uye nekudaro. iyo yakakura shanduko yekupikisa kukosha kweiyo resistor R.. Kureva, mechanical shanduko yesilicon diaphragm inoshandurwa kuva chiratidzo chemagetsi, iyo inowedzerwa nekubatanidza kutenderera uye kubuda kune ECU.

Manifold Absolute Pressure Sensor (MAP). Iyo inobatanidza manifold ekutora nechubhu yevacuum, uye neinjini yekumhanyisa mota yakasiyana, inonzwa shanduko yevacuum mune yakawanda yekudyara, uye yozoishandura kuita chiratidzo chevoltage kubva mukushandurwa kwekupikiswa kwemukati kwe sensor kuti ECU igadzirise. huwandu hwejekiseni yehutsi uye yekubatidza nguva yekona.

MuEFI injini, iyo intake pressure sensor inoshandiswa kuona huwandu hwemhepo inopinza, iyo inonzi D-type jekiseni system (velocity density type). Intake air pressure sensor inoona kutora mhepo yemhepo zvisina kunanga panzvimbo yakananga seyekupinza mhepo inoyerera sensor, uye inobatwawo nezvinhu zvakawanda, saka pane misiyano mizhinji pakati pekuona uye kuchengetedza kwekutora mhepo inoyerera sensor, uye zvikanganiso zvinokonzerwa nazvo zvakare. zvine hunhu hwayo.
