Tora manifold pressure sensor.
Tora manifold pressure sensor chimiro
Nekuti pane amplifier circuit mukati me manifold pressure sensor, inoda huwandu hwewaya nhatu dzetambo yemagetsi, mutsara wepasi uye chiratidzo chekubuda mutsara, izvo zvinewo materminal matatu pamatambo e wiring, zvichiteerana, iyo magetsi terminal (Vcc. ), iyo yepasi terminal (E) uye chiratidzo chinobuda terminal (PIM), uye matatu materminal akabatana nekudzora komputa ECU kuburikidza newaya yekubatanidza uye waya.
Kuti uderedze kuzunguzika kwemukati memagetsi emukati mekutora manifold pressure sensor, inowanzoiswa panzvimbo iyo vibration yemotokari idiki, uye pamusoro peiyo mainin yemhepo inopinza kudzivirira gasi kubva mukupinda manifold kubva pakupinda. iyo pressure sensor. Uye zvakare, iyo manifold manifold pressure sensor inobvuma kupinza pombi kudzvinyirirwa kubva pazasi kudzivirira iyo chiratidzo inonzwa chikamu kubva pakusvibiswa, saka iyo yekupinda pombi gasi inounganidzwa kubva kune yakawandisa manifold padhuze ne throttle kuburikidza nerabha chubhu inosvikirwa kubva kumucheto kwepasi. manifold pressure sensor.
Kuonekwa kweMonomer
1. Kuongororwa kwekuonekwa
Paunenge uchiona, ingo tsvaga hose yerabha kubva kune yakawandisa manifold padhuze neiyo throttle end kuti uwane manifold pressure sensor pamota. Chekutanga, nekiyi yekubatidza yakavharwa, tarisa kuti inopinza manifold pressure sensor waya yekubatanidza yakabatana zvakanaka uye hose yerabha yakadzimwa. Zvadaro tanga injini kuti uone kana hose yerabha isina kuvharwa zvakasimba uye inodonha
2. Kuedzwa kwezviridzwa
(1) BATIDZA switch yemoto (ON), uye edza kukosha kwevoltage pakati peiyo terminal Vcc neE2 ine DC voltage stop yemultimeter (DCV-20). Iko kukosha kwevoltage ndiyo magetsi emagetsi kukosha yakawedzerwa neECU kune manifold pressure sensor. Kukosha kwakajairika kunofanira kuva: Pakati pe4.5 ne5.5V, kana kukosha kusina kunaka, unofanira kutarisa magetsi ebheteri kana kuwirirana pakati petambo, dzimwe nguva dambudziko rinogonawo kuva mukombiyuta yekudzora ECU.
(2) Bvisa iyo yekubatidza switch (ON chinzvimbo), uye dhonza vacuum rabha hose kubva kune inopinza manifold pressure sensor, kuitira kuti iyo yekutora manifold pressure sensor inobatana nemhepo, wozoyedza iyo terminal inobuda voltage chiratidzo ( kukosha kwevoltage pakati pePIM newaya yepasi E2), kukosha kwakajairika ndeku: Pakati pe3.3 ne3.9V, kana iyo voltage inobuda yakawandisa kana yakadzikira, inoratidza kuti intake manifold pressure sensor haina kunaka uye inofanira kutsiviwa.
(3) VARIRA switch yemoto (ON chinzvimbo), bvisa vacuum rabha hose pane yekupinda manifold pressure sensor, shandisa akasiyana negative pressure (vacuum dhigirii) kunotora manifold pressure sensor ine handheld vacuum pombi, uye edza kukosha kwevoltage pakati peiyo wiring terminal transmission voltage chiratidzo PIM uye waya yepasi E2 paunenge uchimanikidza. Iko kukosha kwemagetsi kunofanira kuwedzera mutsara nekukura kwekushandiswa kusina kunaka kudzvinyirirwa, kana zvisina kudaro, inoratidza kuti chiratidzo chekucherechedza dunhu mu sensor chinokanganisa uye chinofanira kutsiviwa.
Ndeipi iyo yekutora manifold pressure sensor iripi?
Iyo yekutora manifold pressure sensor inzwa yakaiswa pane inopinza manifold gasi pombi, iyo matatu waya, imwe ndeye 5 volts, imwe ndeye 5 volts yenzira yekudzoka, kureva, mutsara wakashata, uye imwe chiratidzo. mutsara weEcu.
Iyo yekutora manifold pressure sensor imhando yakakosha ye sensor mu Type D, kureva, velocity density mafuta jekiseni masisitimu, ayo anoita basa rekushandura shanduko yekumanikidza mune yekudyara manifold kuita chiratidzo chevoltage.
Iyo komputa yekudzora (ECU) inosarudza huwandu hwemhepo inopinda mucylinder zvichibva pane iyi chiratidzo uye injini yekumhanyisa (chiratidzo chinopihwa neinjini yekumhanyisa sensor yakaiswa mune inogovera).
Iyo yekupinza pressure sensor inoona iyo yakazara kudzvanywa kweiyo manifold yekutora kuseri kwepfundo uye vharafu, uye inoona shanduko yeakazara kudzvanywa mune yakawanda zvinoenderana nekumhanya kweinjini uye mutoro.
Iyo inozoshandurwa kuita chiratidzo chemagetsi uye inotumirwa kune yemagetsi controller (ECU), iyo inodzora iyo yakakosha jekiseni remafuta maringe nehukuru hweiyo chiratidzo chemagetsi.
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa MG&MAUXS zvikamu zvemotokari zvinogamuchirwa kutenga.
