Sensor ya kuthamanga kwa magazi.
Kapangidwe ka sensor ya kuthamanga kwa magazi ambiri
Popeza pali dera lokulitsa mphamvu mkati mwa sensa ya manifold pressure, imafunika mawaya atatu a chingwe chamagetsi, mzere wapansi ndi mzere wotulutsa chizindikiro, zomwe zimakhala ndi ma terminal atatu pa ma terminal a mawaya, motsatana, terminal yamagetsi (Vcc), terminal yapansi (E) ndi terminal yotulutsa chizindikiro (PIM), ndipo ma terminal atatuwa amalumikizidwa ku kompyuta yowongolera ECU kudzera pa cholumikizira cha waya ndi waya.
Pofuna kuchepetsa kugwedezeka kwa zigawo zamagetsi zamkati mwa sensa ya pressure ya intake manifold, nthawi zambiri imayikidwa pamalo pomwe kugwedezeka kwa galimotoyo kuli kochepa, komanso pamwamba pa mpweya waukulu wa intake kuti mpweya wochokera ku intake manifold usalowe mu sensa ya pressure. Kuphatikiza apo, sensa ya pressure ya intake manifold imalandira kupsinjika kwa payipi ya intake kuchokera pansi kuti iteteze gawo lozindikira chizindikiro kuti lisaipitsidwe, kotero mpweya wa payipi ya intake womwe umasonkhanitsidwa kuchokera ku intake manifold pafupi ndi throttle kudzera mu chubu cha rabara umafikiridwa kuchokera kumapeto kwa sensa ya pressure ya manifold.
Kuzindikira monomer
1. Kuyang'ana mawonekedwe
Mukayang'ana, ingoyang'anani payipi ya rabara kuchokera ku intake manifold pafupi ndi throttle kumapeto kuti mupeze manifold pressure sensor pagalimoto. Choyamba, loko yoyatsira itatsekedwa, onetsetsani kuti cholumikizira cha waya cha intake manifold pressure sensor chalumikizidwa bwino ndipo payipi ya rabara yazimitsidwa. Kenako yatsani injini kuti muwone ngati payipi ya rabara si yotsekedwa bwino komanso yotuluka madzi.
2. Kuyesa zida
(1) Yatsani choyatsira moto (ON), ndikuyesa mphamvu yamagetsi pakati pa terminal Vcc ndi E2 ndi DC voltage stop ya multimeter (DCV-20). Mphamvu yamagetsi ndi mphamvu yamagetsi yowonjezeredwa ndi ECU ku manifold pressure sensor. Mphamvu yamagetsi iyenera kukhala: Pakati pa 4.5 ndi 5.5V, ngati mphamvuyo si yolondola, muyenera kuyang'ana mphamvu yamagetsi ya batri kapena kulumikizana pakati pa mawaya, nthawi zina vuto lingakhalenso mu kompyuta yowongolera ECU.
(2) Yatsani choyatsira moto (ON position), ndikukoka payipi ya rabara ya vacuum kuchokera ku sensor ya pressure ya intake manifold, kuti intake ya sensor ya pressure ya intake manifold ilumikizane ndi mlengalenga, kenako yesani chizindikiro cha terminal output voltage (voltage value pakati pa PIM ndi ground wire E2), mtengo wabwinobwino ndi: Pakati pa 3.3 ndi 3.9V, ngati voltage yotulutsa ndi yokwera kwambiri kapena yotsika kwambiri, zimasonyeza kuti sensor ya pressure ya intake manifold ndi yolakwika ndipo iyenera kusinthidwa.
(3) Yatsani choyatsira moto (ON position), chotsani payipi ya rabara ya vacuum pa sensor ya intake manifold pressure sensor, ikani mphamvu yosiyana yoipa (vacuum degree) pa intake ya sensor ya manifold pressure pogwiritsa ntchito pampu ya vacuum yonyamula m'manja, ndikuyesa mphamvu ya voltage pakati pa chizindikiro cha wiring terminal transmission voltage PIM ndi waya wapansi E2 pamene mukugwiritsa ntchito mphamvu. Mphamvu ya voltage iyenera kuwonjezeka motsatizana ndi kukula kwa mphamvu yoipa yomwe yagwiritsidwa ntchito, apo ayi, zimasonyeza kuti dera lozindikira chizindikiro mu sensa ndi lolakwika ndipo liyenera kusinthidwa.
Kodi sensa ya kuthamanga kwa magazi ya intake manifold ili kuti?
Sensor ya intake manifold pressure ndi sensor yomwe imayikidwa pa chitoliro cha gasi cha intake manifold, chomwe mawaya atatu, imodzi ndi ya ma volts 5, imodzi ndi ya ma volts 5 a njira yobwerera, ndiko kuti, mzere woyipa, ndipo inayo ndi mzere wa chizindikiro cha Ecu.
Sensor ya intake manifold pressure ndi mtundu wofunikira kwambiri wa sensor mu Type D, kutanthauza, velocity density fuel injection systems, yomwe imagwira ntchito yosintha kusintha kwa kuthamanga kwa intake manifold kukhala chizindikiro cha voltage.
Kompyuta yowongolera (ECU) imazindikira kuchuluka kwa mpweya wolowa mu silinda kutengera chizindikiro ichi ndi liwiro la injini (chizindikiro choperekedwa ndi sensa ya liwiro la injini yomwe yayikidwa mu chogawa).
Chojambulira mphamvu ya intake chimazindikira kupanikizika konse kwa intake manifold kumbuyo kwa knot ndi valavu, ndipo chimazindikira kusintha kwa kupsinjika konse mu manifold malinga ndi liwiro la injini ndi katundu wake.
Kenako imasinthidwa kukhala magetsi oyendera chizindikiro ndipo imatumizidwa ku chowongolera zamagetsi (ECU), chomwe chimayang'anira kuchuluka kwa mafuta oyambira kutengera kukula kwa magetsi oyendera chizindikirochi.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
