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 materminals matatu pamatambo ewaya, zvichiteerana, iyo terminal yemagetsi (Vcc), iyo yepasi terminal (E) uye chiratidzo chinobuda terminal (PIM), uye matatu materminal akabatana nekombuta yekudzora ECU newaya yekubatanidza.
Kuti uderedze kudzungudza kwemukati memagetsi emukati mekutora manifold pressure sensor, inowanzoiswa munzvimbo iyo kudengenyeka kwemotokari kunenge kudiki, uye pamusoro peiyo mainin yemhepo inopinza kudzivirira gasi kubva pakupinda manifold kubva pakupinda mukumanikidza sensor. Uye zvakare, iyo yekupinda manifold pressure sensor inobvuma kupinza pombi kudzvanywa kubva pazasi kudzivirira iyo chiratidzo inonzwa chikamu kubva pakusvibiswa, saka iyo pombi yekupinda gasi inounganidzwa kubva kune yakawandisa manifold padhuze ne throttle kuburikidza nerabha chubhu inosvikirwa kubva kumucheto kwezasi kwe 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) Batidza switch yeginition (ON chinzvimbo), uye dhonza vacuum rabha hose kubva kune yekudyara manifold pressure sensor, kuitira kuti kutora kweiyo intake manifold pressure sensor yakabatana nemhepo, wobva waedza iyo terminal inobuda voltage chiratidzo (voltage kukosha pakati pePIM nepasi waya E2), kukosha kwakajairika ndeku: Pakati pe3.3 ne3. kutora manifold pressure sensor haina kunaka uye inofanira kutsiviwa.
(3) VARIRA switch yemoto (ON chinzvimbo), bvisa vacuum rabha hose pane inopinza manifold pressure sensor, shandisa zvakasiyana-siyana zvisina kunaka (vacuum degree) kunotora manifold pressure sensor ine handheld vacuum pombi, uye edza kukosha kwevoltage pakati peiyo wiring terminal transmission voltage signal PIM uye waya yepasi E2 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 sensor yakaiswa pane inopinza manifold gasi pombi, iyo mawaya matatu, imwe ndeye 5 volts, imwe ndeye 5 volts yenzira yekudzokera, kureva, mutsara wakashata, uye imwe mutsara wechiratidzo 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.
