Imwani manifold pressure sensor.
Imalowetsani mawonekedwe a sensor pressure
Chifukwa pali amplifier dera mkati zobwezedwa kukakamiza kachipangizo, pamafunika okwana mawaya atatu a mzere mphamvu, mzere pansi ndi mzere linanena bungwe chizindikiro, amene mofanana ndi materminal atatu pa mawaya terminals, motero, mphamvu terminal (Vcc), terminal pansi (E) ndi otsiriza chizindikiro linanena bungwe (PIM), ndi materminal atatu olumikizidwa ku ulamuliro kompyuta ECU ndi waya cholumikizira ndi waya.
Pofuna kuchepetsa kugwedezeka kwa zida zamkati zamagetsi zamagetsi zamagetsi zamagetsi, nthawi zambiri zimayikidwa pamalo pomwe kugwedezeka kwagalimoto kumakhala kochepa, komanso pamwamba pa mpweya wolowetsa mpweya kuti muteteze gasi kuchokera ku manifold olowa kuti asalowe mu sensor ya pressure. Kuphatikiza apo, cholumikizira choponderetsa chochulukirapo chimavomereza kukakamiza kwa chitoliro kuchokera pansi kuti chiteteze gawo lomvera ma siginecha kuti lisaipitsidwe, kotero kuti mpweya wa chitoliro cholowetsedwa womwe umasonkhanitsidwa kuchokera kumalo olowera pafupi ndi throttle kudzera mu chubu cha rabara umapezeka kuchokera kumapeto kwenikweni kwa sensor yokakamiza yochuluka.
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 chosinthira choyatsira (pamalo), ndikukoka payipi ya mphira ya vacuum kuchokera pa sensa yolowera, kuti kulowetsedwa kwa sensa yolumikizirana kumalumikizidwa ndi mlengalenga, ndiye yesani chizindikiro chamagetsi otsika (mtengo wamagetsi pakati pa PIM ndi waya wapansi E2), mtengo wabwinobwino ndi: Pakati pa 3.3 ndi 3. sensa ya manifold pressure sensor ndiyolakwika ndipo iyenera kusinthidwa.
(3) Yatsani choyatsira choyatsira (POYENERA malo), chotsani payipi ya rabara ya vacuum pa sensa yolowera, ikani kupanikizika kosiyanasiyana (digiri ya vacuum) kuti mutenge sensor yoponderezedwa ndi pampu yapam'manja, ndikuyesa mtengo wa voliyumu pakati pa mawotchi opangira ma waya otumizira voteji PIM ndi waya wapansi E2 mukamagwiritsa ntchito mphamvu. 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?
Kuthamanga kochulukira kachipangizo kachipangizo kamene kamayikidwa pa chitoliro cha gasi, chomwe mawaya atatu, chimodzi ndi 5 volts, chimodzi ndi 5 volts ya njira yobwerera, ndiko kuti, mzere wolakwika, ndi winayo ndi mzere wa chizindikiro cha 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.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zolandiridwa kuti mugule.
