Galimoto intake pressure sensor ntchito
Yang'anirani kuchuluka kwa kuthamanga kwa magazi
Sensor ya intake pressure imalumikizidwa ndi ma intake manifold kudzera mu chubu cha vacuum kuti izindikire kusintha kwamphamvu kwapang'onopang'ono kuseri kwa valavu ya throttle munthawi yeniyeni. Kusintha kumeneku kumagwirizana kwambiri ndi liwiro ndi katundu wa injini, ndipo masensa amasintha kusintha kwa makinawa kukhala zizindikiro zamagetsi zomwe zimatumizidwa ku ECU.
Konzani jekeseni wamafuta
Kutengera chizindikiro chokakamiza choperekedwa ndi sensa, ECU imawerengera molondola kuchuluka kwamafuta omwe amafunikira injini. Pamene katundu wa injini ukuwonjezeka, kupanikizika kobwezedwako kumachepa, chizindikiro cha sensa chimawonjezeka, ndipo ECU imawonjezera kuchuluka kwa jekeseni wamafuta moyenerera. Apo ayi, idzachepa. Kusintha kwamphamvu kumeneku kumapangitsa kuti injini igwire bwino ntchito pamikhalidwe yosiyanasiyana yogwirira ntchito.
Control nthawi kuyatsa
Sensor pressure intake imathandizanso ECU kusintha nthawi yoyatsira. Pamene kuchuluka kwa injini kukuchulukirachulukira, njira yoyatsira patsogolo idzachedwa moyenerera. Pamene katundu wachepetsedwa, poyatsira patsogolo Angle adzapita patsogolo. Kusintha kumeneku kumathandizira kupititsa patsogolo mphamvu ya injini komanso kuchepa kwamafuta.
Kuwerengera kwa mpweya wothandiza
Mumtundu wa jekeseni wamafuta amtundu wa D, mphamvu yamagetsi yolowera imagwiritsidwa ntchito molumikizana ndi mita yoyendera mpweya kuti muyeze kuchuluka kwa kulowetsedwa mosalunjika, potero kuwerengera mpweya wabwino kwambiri. Ntchito yothandizana iyi imakulitsanso jakisoni wamafuta ndi magwiridwe antchito a injini.
Kuzindikira zolakwika ndi chitetezo
Sensor yothamanga ya intake imatha kuzindikira kusintha kwamphamvu kwapang'onopang'ono pakudya, monga ma clogs kapena kutayikira, ndikutumiza zizindikiro ku ECU. Izi zimathandizira kuzindikira kulephera kwa injini munthawi yake ndikutenga njira zodzitetezera kuti zisawonongeke.
Mitundu ndi mfundo zogwirira ntchito
Masensa omwe amamwa kwambiri amaphatikiza mitundu ya varistor ndi capacitive. Sensa ya varistor imasintha kukana kudzera pakusinthika kwa silicon diaphragm ndikutulutsa chizindikiro chamagetsi. Sensor capacitive imasintha mtengo wa capacitance kudzera pakusinthika kwa diaphragm ndikutulutsa chizindikiro cha pulse. Masensa onsewa amagwiritsidwa ntchito kwambiri m'magalimoto amakono chifukwa cha kulondola kwawo komanso kuyankha mwachangu.
Chidule mwachidule
Sensor ya intake pressure sensor ndi imodzi mwazinthu zazikuluzikulu zamakina owongolera injini yamagalimoto, gawo lake silimangoyang'anira kuthamanga, komanso kuphatikizidwa ndi jakisoni wamafuta, nthawi yoyatsira, kuwerengera mpweya komanso kuzindikira zolakwika. Mwa kuwongolera bwino magawo awa, masensa amathandizira kwambiri magwiridwe antchito a injini, kuchepa kwamafuta ndi mpweya.
Magalimoto amatengera kuthamanga sensa (kudya kuthamanga sensa) ndi chimodzi mwa zigawo zikuluzikulu za dongosolo mafuta jakisoni, kulephera kwake kungachititse injini ulamuliro unit (ECU) sangathe molondola kusintha chiŵerengero mpweya-mafuta. Izi ndi zizindikiro zazikulu ndi zomwe zimayambitsa vutolo:
Chiwonetsero chazizindikiro zazikulu
Kuvuta kapena kulephera kuyambitsa injini
Zizindikiro za sensa zachilendo zidzachititsa ECU kulephera kuwerengera kuchuluka kwa jekeseni wamafuta, zomwe zimakhudza mwachindunji kuyatsa ndi jekeseni wamafuta.
Ngati mzere wa sensa wathyoledwa kapena wofupikitsidwa, ECU ikhoza kutaya kwathunthu deta yokakamiza kudya, zomwe zingayambitse kulephera koyambitsa.
Kutulutsa mphamvu kwachilendo
Kuthamanga kosakwanira kapena kuchepa kwa mphamvu: sensa siyingasinthe siginecha ndikusintha kwa vacuum degree, ndipo ECU imawerengera molakwika mpweya, zomwe zimapangitsa kuti kuchuluka kwa jakisoni wamafuta kuchepe.
Liwiro losakhazikika losagwira ntchito : Kusakaniza kukachuluka kapena kuonda kwambiri, injini imatha kunjenjemera kapena kusinthasintha.
kuyaka anomaly
Utsi wakuda wochokera ku chitoliro cha exhaust : kusakaniza kwake ndi kokhuthala kwambiri kuti kungayambitse kuyaka kosakwanira, komwe kumawoneka mofulumira kwambiri.
Kutentha kwa chitoliro: Pamene kusakaniza kuli kopyapyala kwambiri, gasi wosayaka amayaka mupaipi yolowera.
Kugawa chifukwa cha zolakwika
Sensor yokha
Kuyesa kwapakati kapena kulephera kuzungulira (mwachitsanzo, kulephera kwa semiconductor strain gauge).
Mphamvu yamagetsi yotulutsa imaposa kuchuluka kwanthawi zonse (monga voltage drift).
kulephera kogwirizana ndi kunja
Paipi ya vacuum yatsekedwa kapena kutayikira, zomwe zimakhudza kufalikira kwa kuthamanga.
Kuyika kolakwika kwa mphete yosindikizira kumabweretsa kutsekeka kwa cholowetsa choponderezedwa (kusintha kwa siginecha panthawi yamavuto).
Lingaliro la matenda
Kufufuza koyambirira
Yang'anani ngati nyali yolakwika yayatsidwa (zitsanzo zina zidzayambitsa nambala yolakwika ya OBD).
Yang'anani kulumikizidwa kwa mapaipi a vacuum ndi waya wa sensa.
Kuyesa kwa akatswiri
Gwiritsani ntchito zowunikira kuti muwerenge mayendedwe anthawi yeniyeni ndikuyerekeza kupanikizika kokhazikika.
Yesani ngati mphamvu yotulutsa sensa imasiyanasiyana ndi kutsegula kwa throttle.
Langizo : Ngati zizindikiro zomwe zili pamwambazi zikutsagana ndi zolakwika (monga P0105/P0106), sensa ndi mabwalo okhudzana nawo ayenera kuyang'aniridwa kaye. Kunyalanyaza kwanthawi yayitali kungayambitse kuwonongeka kwa chosinthira chothandizira chanjira zitatu kapena kuwonjezeka kwakukulu kwamafuta.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. adadzipereka kugulitsa zida zamagalimoto za MG&750 zolandilidwa kugula.
