Imwani manifold pressure sensor.
Imalowetsani kachitidwe ka sensa yothamanga kwambiri
Chifukwa pali dera la amplifier mkati mwa sensa yothamanga kwambiri, imafunikira mawaya atatu onse a chingwe chamagetsi, mzere wapansi ndi mzere wotulutsa chizindikiro, womwenso uli ndi ma terminals atatu pa ma wiring terminals, motsatana, malo opangira magetsi (Vcc). ), malo otsetsereka pansi (E) ndi cholumikizira chizindikiro (PIM), ndipo ma terminals atatu amalumikizidwa ndi kompyuta yolamulira ECU kudzera pa cholumikizira waya ndi waya.
Pofuna kuchepetsa kugwedezeka kwa zigawo zamkati zamagetsi a intake manifold pressure sensor, nthawi zambiri zimayikidwa pamalo pomwe kugwedezeka kwa galimoto kumakhala kochepa, ndipo pamwamba pa mpweya wolowetsa mpweya kuti ateteze gasi kuchokera ku manifold ambiri. sensor ya pressure. Kuphatikiza apo, cholumikizira chowonjezera chowonjezera chimavomereza kukakamiza kwa chitoliro kuchokera pansi kuti chiteteze gawo lomvera ma sign kuti lisaipitsidwe, kotero kuti mpweya wa chitoliro cholowetsera womwe umasonkhanitsidwa kuchokera kumalo olowera pafupi ndi throttle kudzera mu chubu la rabara umapezeka kuchokera kumapeto kwenikweni kwa mphira. manifold pressure sensor.
Kuzindikira kwa monomer
1. Kuyang'anira maonekedwe
Mukayang'ana, ingopezani payipi ya rabara kuchokera kumalo olowera pafupi ndi kumapeto kwa throttle kuti mupeze makina osindikizira amagetsi pagalimoto. Choyamba, ndi loko yoyatsira itatsekedwa, fufuzani kuti cholumikizira cholumikizira waya cholumikizira cholumikizira chalumikizidwa bwino ndipo payipi ya rabara yazimitsidwa. Kenako yambani injini kuti muwone ngati payipi ya rabara siinasindikizidwa mwamphamvu komanso ikutha
2. Kuyezetsa zida
(1) YAtsani choyatsira (ON), ndipo yesani mtengo wamagetsi pakati pa Vcc ndi E2 ndi DC voltage stop ya multimeter (DCV-20). Mtengo wamagetsi ndi mphamvu yamagetsi yamagetsi yowonjezeredwa ndi ECU ku sensa yothamanga kwambiri. Mtengo wabwinobwino uyenera kukhala: Pakati pa 4.5 ndi 5.5V, ngati mtengo uli wolakwika, muyenera kuyang'ana voteji ya batri kapena kulumikizana pakati pa mawaya, nthawi zina vuto lingakhalenso mu ECU yolamulira kompyuta.
(2) Yatsani choyatsira choyatsira (POGWIRITSA NTCHITO), ndikukokera payipi ya mphira ya vacuum kuchokera pa sensa yothamanga kwambiri, kuti kulowetsedwa kwa sensor yamagetsi yolumikizirana kumalumikizidwa ndi mlengalenga, kenako yesani chizindikiro chamagetsi ( mtengo wamagetsi pakati pa PIM ndi waya wapansi E2), mtengo wabwinobwino ndi: Pakati pa 3.3 ndi 3.9V, ngati voteji yotulutsa ndi yokwera kwambiri kapena yotsika kwambiri, ikuwonetsa kuti sensor yokakamiza yochulukirapo ndiyolakwika ndipo iyenera kusinthidwa.
(3) YATSANI choyatsira choyatsira (ON malo), chotsani payipi ya mphira wa vacuum pa sensa yolowera, ikani kuthamanga kosiyana kosiyana (digiri ya vacuum) kuti mutenge sensor yamphamvu yochulukirapo yokhala ndi pampu yopumira m'manja, ndikuyesa Mtengo wa voteji pakati pa mawotchi otumizira mawaya chizindikiro cha PIM ndi waya wapansi E2 mukamagwiritsa ntchito kukakamiza. Mtengo wa voliyumu uyenera kuwonjezeka molingana ndi kukula kwa kukakamiza koyipa komwe kumagwiritsidwa ntchito, apo ayi, zikuwonetsa kuti dera lozindikira ma siginecha mu sensa ndi lolakwika ndipo liyenera kusinthidwa.
Kodi ma intake manifold pressure sensor ili kuti?
Sensa yothamanga kwambiri ndi sensa yomwe imayikidwa pa chitoliro cha gasi, chomwe mawaya atatu, imodzi ndi 5 volts, imodzi ndi 5 volts ya njira yobwerera, ndiye kuti, mzere wolakwika, ndi winayo ndi chizindikiro. mzere wa Ecu.
Sensor yothamanga kwambiri ndi mtundu wofunikira kwambiri wa sensa yamtundu wa D, ndiye kuti, makina ojambulira mafuta othamanga kwambiri, omwe amatenga gawo losintha kusintha kwamphamvu kwa ma intake kukhala siginecha yamagetsi.
Kompyuta yolamulira (ECU) imatsimikizira kuchuluka kwa mpweya womwe umalowa mu silinda kutengera chizindikiro ichi ndi liwiro la injini (chizindikiro choperekedwa ndi sensor liwiro la injini yomwe imayikidwa mu wogawa).
The intake pressure sensor imazindikira kupanikizika kotheratu kwa kuchuluka kwa kulowetsedwa kuseri kwa mfundo ndi valavu, ndipo imazindikira kusintha kwamphamvu kokwanira mosiyanasiyana malinga ndi liwiro la injini ndi katundu.
Imasinthidwa kukhala voteji yamagetsi ndikutumizidwa kwa chowongolera zamagetsi (ECU), chomwe chimawongolera kuchuluka kwa jakisoni wamafuta malinga ndi kukula kwa voteji iyi.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
