Sensor yekumanikidza inopinda muropa.
Chimiro che sensor yekumanikidza yakawanda yekudya
Nekuti mune amplifier circuit mukati me manifold pressure sensor, inoda waya nhatu dzemagetsi, ground line nesignal output line, idzo dzine materminal matatu pa wiring terminals, zvichiteerana, power terminal (Vcc), ground terminal (E) nesignal output terminal (PIM), uye materminals matatu akabatana ne control computer ECU kuburikidza ne wire connector newaya.
Kuti kuderedze kudedera kwezvikamu zvemagetsi zvemukati zve intake manifold pressure sensor, inowanzoiswa panzvimbo apo kudedera kwemotokari kuri kudiki, uye pamusoro pe intake air main kudzivirira gasi kubva ku intake manifold kuti isapinde mu pressure sensor. Pamusoro pezvo, intake manifold pressure sensor inogamuchira intake pipe pressure kubva pasi kudzivirira chikamu chinonzwa masaini kuti chisasvibiswe, saka gasi re intake pipe rinounganidzwa kubva ku intake manifold pedyo ne throttle kuburikidza ne rabha tube rinosvikika kubva kumucheto wepasi we manifold pressure sensor.
Kuonekwa kweMonomer
1. Kuongorora chitarisiko
Paunenge uchitarisa, ingotsvaga hosipaipi yerabha kubva pa intake manifold pedyo ne throttle end kuti uwane manifold pressure sensor iri pamota. Kutanga, kana ignition lock yakavharwa, tarisa kuti intake manifold pressure sensor wire connector yakabatana zvakanaka uye kuti hosipaipi yerabha yadzimwa. Wobva watanga injini kuti uone kana hosipaipi yerabha isina kuvharwa zvakanaka uye isina kubuda mvura.
2. Kuedzwa kwemidziyo
(1) Batidza switch yekupisa (ON), uye edza voltage value pakati pe terminal Vcc ne E2 neDC voltage stop ye multimeter (DCV-20). Voltage value ndiyo power supply voltage value inowedzerwa neECU kune manifold pressure sensor. Yakajairika inofanira kuva: Pakati pe 4.5 ne 5.5V, kana kukosha kwacho kusina kururama, unofanira kutarisa voltage yebhatiri kana kubatana pakati pewaya, dzimwe nguva dambudziko rinogonawo kuva mu control computer ECU.
(2) Batidza switch yekupisa (ON position), uye dhonza vacuum rabber hose kubva ku intake manifold pressure sensor, kuitira kuti intake ye intake manifold pressure sensor ibatanidzwe nemhepo, wobva waedza terminal output voltage signal (voltage value iri pakati pePIM neground wire E2), yakajairika kukosha kwayo ndeiyi: Pakati pe3.3 ne3.9V, kana output voltage yakakwira zvakanyanya kana kuti yakaderera zvakanyanya, zvinoratidza kuti intake manifold pressure sensor haina kunaka uye inofanira kutsiviwa.
(3) Batidza switch yekupisa (ON position), bvisa pombi yerabha yevacuum iri pa intake manifold pressure sensor, isa pressure yakasiyana (vacuum degree) pa intake ye manifold pressure sensor uchishandisa vacuum pombi inobatwa neruoko, uye edza voltage value iri pakati pe wiring terminal transmission voltage signal PIM neground wire E2 paunenge uchishandisa pressure. Voltage value inofanira kuwedzera linearly nekukura kwe applied negative pressure, zvikasadaro, zvinoratidza kuti signal detection circuit iri mu sensor haina kunaka uye inofanira kutsiviwa.
Chinoongorora kumanikidzwa kwemuchina we intake manifold chiri kupi?
Intake manifold pressure sensor i sensor yakaiswa pa intake manifold gas pipe, ine waya nhatu, imwe ndeye 5 volts, imwe ndeye 5 volts yenzira yekudzoka, kureva kuti, negative line, uye imwe ndeye signal line yeEcu.
Intake manifold pressure sensor imhando yakakosha ye sensor muType D, kureva, velocity density fuel injection systems, iyo inoita basa rekushandura pressure change mu intake manifold kuita voltage signal.
Komputa yekudzora (ECU) ndiyo inosarudza huwandu hwemhepo inopinda mu cylinder zvichibva pachiratidzo ichi uye kumhanya kweinjini (chiratidzo chinopihwa ne sensor yekumhanya kweinjini yakaiswa mumugovanisi).
Chinoongorora kumanikidzwa kwemuchina weintake chinoona kumanikidzwa kwemuchina weintake uri kuseri kwepfundo nevharuvhu, uye chinoona kuchinja kwekumanikidzwa kwemuchina weintake zvichienderana nekumhanya kweinjini nemutoro.
Inozoshandurwa kuita voltage yechiratidzo yotumirwa kune electronic controller (ECU), iyo inodzora huwandu hwemafuta anoshandiswa zvichienderana nehukuru hwevoltage yechiratidzo ichi.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
