Kodi choyezera liwiro la injini ya galimoto chimatanthauza chiyani?
Sensa yothamanga ya injini yamagalimoto ndi gawo lofunikira lomwe limasintha liwiro la injini kukhala chizindikiro chamagetsi ndipo ndi imodzi mwa masensa ofunikira mu dongosolo lowongolera zamagetsi zamagalimoto. Imazindikira mayendedwe ozungulira a crankshaft kapena camshaft, imayang'anira magawo ogwirira ntchito a injini (monga liwiro lozungulira, ngodya yozungulira, ndi zina zotero) nthawi yeniyeni, ndipo imasintha kuchuluka kumeneku kukhala zizindikiro zamagetsi kuti zitumizidwe ku unit yowongolera injini, motero kukwaniritsa kuwongolera kolondola kwa magawo monga kulowetsa mafuta ndi nthawi yoyatsira, kuonetsetsa kuti injini ikugwira ntchito bwino komanso mokhazikika.
Ntchito yaikulu
Amagwiritsidwa ntchito makamaka kuyang'anira liwiro la injini ndi malo a crankshaft, kupereka zizindikiro zowonetsera gawo lowongolera, kukonza kuchuluka kwa mafuta ojambulira ndi nthawi yoyatsira, kuwonjezera magwiridwe antchito amagetsi ndikuchepetsa kugwiritsa ntchito mafuta.
Mitundu ndi Mapulogalamu
Mitundu yodziwika bwino ndi monga mtundu womvera maginito, mtundu wa photoelectric, mtundu wa Hall effect, ndi zina zotero, zomwe zimagwiritsidwa ntchito kwambiri m'magawo monga magalimoto, zida zamakina a CNC, komanso kupanga mphamvu zamphepo.
Sensa yothamanga yowonongeka ingayambitse zolakwika m'dongosolo monga kuyambitsa kovuta, mphamvu yolakwika, ndi ma alarm a zida m'galimoto, zomwe zimakhudza mwachindunji momwe injini imagwirira ntchito komanso chitetezo choyendetsa.
Youdaoplaceholder0 Core fault phenomenon
Youdaoplaceholder0 Kuvuta poyambitsa : Kumaonekera ngati kufunika kwa kuyatsa kambirimbiri kapena kuponda pa accelerator kuti ayambe, chifukwa sensa singathe kutumiza molondola chizindikiro cha malo a crankshaft, zomwe zimapangitsa kuti kulephera kwa kuwongolera kwa jakisoni wa mafuta kulephereke.
Youdaoplaceholder0 idle speed anomaly :
Injini ikugwedezeka kwambiri ndipo cholozera cha tachometer chimasintha kwambiri.
Zimakhala zovuta kuima mwadzidzidzi zikamadikirira pa magetsi a magalimoto.
Youdaoplaceholder0 mphamvu ikugwira ntchito ikuchepa :
Kuthamanga kofooka komanso kuyankha pang'onopang'ono kwa throttle.
Liwiro lalikulu kwambiri ndi lochepa, ndipo "kulephera" kungachitike kuti kukhazikitse malire a liwiro.
Youdaoplaceholder0 imayambitsa zoopsa zachitetezo
Kuwonjezeka kosazolowereka kwa kugwiritsa ntchito mafuta: Chifukwa cha njira yosungira mafuta yomwe idagwiritsidwa ntchito ndi ECU, kusalinganika kwa kuchuluka kwa mafuta osakaniza kumabweretsa kuchepa kwa 30%-50% pakugwiritsa ntchito bwino mafuta.
Cholakwika cha Youdaoplaceholder0 cholumikizira alamu yabodza ndi cholakwika cholumikizira makina:
Nyali ya injini, nyali ya ABS, nyali ya batri ndi magulu ena a nyali zochenjeza zonse zimayatsidwa pamodzi.
Kusuntha kwa magiya kwa magiya odziyimira pawokha ndi kosakhazikika, ndipo kutsekeka kwa magiya kumatha kuchitika.
Youdaoplaceholder0 chiopsezo cha mikhalidwe yoopsa yogwirira ntchito :
Kuwonjezeka kwadzidzidzi kwa liwiro la injini panthawi yoyendetsa (komwe kumachitika nthawi zambiri mukalephera kugwiritsa ntchito sensa ya liwiro la fan).
Ikachepa mphamvu, injini imayima kwathunthu, zomwe zimapangitsa kuti chowongolera/chothandizira kuletsa mabuleki.
Youdaoplaceholder0 Malo owunikira ndi kukonza
Njira yodziwira matenda
Yesani kukana kwa sensa ndi multimeter (mtengo wabwinobwino: 0.7-1.2kΩ).
Yang'anani ngati pali ma circuit afupi kapena ma circuit otseguka mu mawaya.
Kuyankha mwadzidzidzi
Zimitsani nthawi yomweyo zipangizo zamagetsi monga ma air conditioner.
Pewani kuthamangitsa galimoto mwadzidzidzi ndipo yendetsani bwino kupita kumalo okonzera.
Malangizo osinthira
Perekani patsogolo zida zoyambirira za fakitale (zokhala ndi chiwopsezo chochepera 0.5%).
Mukakhazikitsa, tsatirani mosamalitsa muyezo wa torque (nthawi zambiri 8-10N·m).
Sensa yozungulira liwiro, yokhala ndi magnetoresistor ngati chinthu chowunikira, ndi mtundu watsopano wa sensa yozungulira liwiro. Gawo lalikulu limagwiritsa ntchito magnetoresistor ngati chinthu chozindikira, kenako kudzera mu dera latsopano lokonza zizindikiro, phokoso limachepa ndipo ntchito imakhala yokwanira. Poyerekeza ma waveform otulutsa ndi a mitundu ina ya masensa othamanga a giya, cholakwika choyezedwa liwiro chimakhala chochepa kwambiri ndipo mawonekedwe a mzere ndi ofanana kwambiri. Cholinga cha induction ndi zinthu zamaginito kapena ferromagnetic, monga chitsulo chamaginito, chitsulo ndi chitsulo chamagetsi, ndi zina zotero. Chinthu chomwe chikuyesedwa chikakhala ndi ma protrusions (kapena depressions) a zinthu zamaginito kapena ferromagnetic, pamene chinthucho chikuzungulira, sensa imatulutsa chizindikiro cha pulse chokhudzana ndi pafupipafupi yozungulira, kukwaniritsa cholinga choyezera liwiro kapena kuzindikira kusamuka.
Sensa yothamanga ya giya ili ndi zinthu izi:
Kuzindikira kwambiri, kudalirika kwambiri, moyo wautali komanso mtunda wautali woyimbira
Choyambitsa chizindikirocho chimapangidwa ndi zinthu zamaginito zachitsulo (zofewa)
Imatha kuyenda mtunda wautali ndipo ili ndi mphamvu yolimbana ndi maginito owononga mphamvu zamagetsi
Kukana bwino kugwedezeka komanso kukana zivomerezi.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa MG&MAXUSzida zamagalimoto zalandiridwa kugula.
