Wowongolera Kuchaja: Woyang'anira Wosawoneka ndi Woyankha Zolakwika za Dongosolo Lamagetsi a Magalimoto
Mu dongosolo lamphamvu lovuta la galimoto, ngakhale kuti chowongolera cha chaji sichili chodziwika bwino monga injini kapena bokosi la gearbox, chimagwira ntchito yofunika kwambiri. Chili ngati chowongolera cholondola chomwe nthawi zonse chimasintha magawo kutengera momwe injini imagwirira ntchito kuti chitsimikizire kuti mphamvu yochokera ku galimotoyo ikuyenda bwino komanso yokhazikika.
Ntchito yaikulu ya chowongolera chagalimoto
Chowongolera chagalimoto chimagawidwa makamaka m'magulu owongolera chaja chamagetsi ndi owongolera gawo la injini, chilichonse chikuchita ntchito zake kuti galimoto igwire bwino ntchito.
Mu dongosolo lamagetsi la galimoto, chowongolera chajayira chili ndi udindo wofunikira kwambiri pakukhazikitsa mphamvu yamagetsi. Liwiro la injini ndi lalikulu, ndipo mphamvu yamagetsi yotulutsa ya jenereta imasintha moyenerera. Zipangizo zamagetsi mkati mwa galimoto, monga magetsi amagetsi, makina amawu, ndi kuyenda mgalimoto, zonse zimafuna mphamvu yamagetsi yokhazikika kuti zigwire ntchito bwino. Chowongolera chajayira chimalamulira kukula kwa mphamvu yamagetsi mkati mwa jenereta, kuwonjezera mphamvu yamagetsi pamene liwiro la injini lili lotsika ndikuchepetsa mphamvu yamagetsi pamene liwiro lili lalikulu, kukhazikitsa mphamvu yamagetsi yotulutsa ya jenereta pamtengo wovomerezeka (nthawi zambiri pafupifupi 14.0V) kuti zitsimikizire kuti zida zamagetsi za galimotoyo sizikhudzidwa ndi kusinthasintha kwa mphamvu yamagetsi. Nthawi yomweyo, ilinso ndi ntchito zoletsa mphamvu yamagetsi yochulukirapo ndikudula mphamvu yamagetsi yobwerera, kupewa kuwonongeka kwa batri ndi jenereta chifukwa cha mphamvu yamagetsi yochuluka, kupewa kutulutsa kwa batri mopitirira muyeso ndi kuwonongeka kwa ma windings a jenereta, ndikuwonjezera moyo wa batri ndi jenereta.
Woyang'anira gawo la injini amayang'ana kwambiri pakukonza bwino mphamvu ya kuyaka kwa injini. Mwachitsanzo, wowongolera gawo la VVT amatha kusintha gawo la camshaft malinga ndi kusintha kwa momwe injini imagwirira ntchito, potero kusintha kuchuluka kwa intake ndi utsi, kuwongolera nthawi yotsegulira ndi kutseka ndi ngodya ya ma valve. Mu mikhalidwe ya liwiro lochepa kapena lochepa, wowongolera gawo la intake adzapititsa patsogolo nthawi yotseka ya intake valavu, kupanga kugwedezeka kwafupipafupi, kukulitsa kugwedezeka ndi mphamvu yozungulira mu silinda, kupangitsa kuti chisakanizocho chikhale chofanana, kukonza kukhazikika kwa kuyaka, ndikuwonjezera kutulutsa kwa torque yotsika, kupangitsa galimoto kuyamba bwino; injini ikakhala pa liwiro lalikulu kapena mikhalidwe ya katundu wambiri, idzachedwetsa nthawi yotseka ya intake valavu, kuonjezera kutalika kwa intake stroke, kulola mpweya wambiri kulowa mu silinda, ndikugwirizana ndi nthawi yolowetsa mafuta pambuyo pake kuti apange chisakanizo chokhuthala, kuonjezera mphamvu ya injini, kukwaniritsa zosowa za kuthamanga kwa galimoto kapena kuyendetsa mwachangu.
Zizindikiro zodziwika bwino za kulephera kwa chowongolera cha chaji chagalimoto
Chowongolera cha galimoto chikalephera, chimasonyeza zolakwika m'mbali zosiyanasiyana za galimotoyo.
Pamene chowongolera chamagetsi chalephera, chodziwika kwambiri ndichakuti jenereta sipanga magetsi. Panthawiyi, kuwala kwa batri pa dashboard kumayatsa, zomwe nthawi zambiri zimachitika chifukwa cha kuwonongeka kwa transistor yamagetsi kapena transistor ya Darlington. Pakhoza kukhalanso vuto la kupanga magetsi mopitirira muyeso, zomwe zimapangitsa batri kudzaza kwambiri, zomwe zimakhudza moyo wa batri, komanso kubweretsa kuwonongeka kwa batri, komwe kumawonetsedwa ngati magetsi a batri pansi pa 10V, zomwe zimapangitsa kuti galimoto ikhale yovuta kuyamba. Kuphatikiza apo, chowongolera chamagetsi chowonongeka chingayambitsenso galimoto kukhala ndi vuto lothamanga, kugwiritsa ntchito mafuta ambiri, komanso kukhudza kwambiri magwiridwe antchito a galimoto.
Kulephera kwa chowongolera gawo la injini kudzakhudza mwachindunji mphamvu ya injini komanso kugwiritsa ntchito mafuta moyenera. Ikalephera, injini ikhoza kukhala ndi kusasunthika kosakhazikika, kugwedezeka kwambiri, kutulutsa mphamvu kochepa, komanso kuyambika pang'onopang'ono kwa galimoto; pa liwiro lalikulu, mphamvu yotulutsa singafike pamlingo wabwinobwino, ndipo magwiridwe antchito othamanga adzachepa. Nthawi yomweyo, chifukwa cha kuchepa kwa mphamvu yoyaka, kugwiritsa ntchito mafuta kwa galimoto kudzawonjezeka kwambiri, ndipo kutulutsa utsi kumatha kupitirira muyezo.
Kuzindikira ndi kuthetsa kulephera kwa chowongolera chagalimoto
Pa vuto la chowongolera chamagetsi, njira zaukadaulo zodziwira matenda zingagwiritsidwe ntchito. Mwachitsanzo, poyang'ana galimoto, magetsi a DC osinthika a 10 - 20V (kapena 20 - 40V) angagwiritsidwe ntchito, olumikizidwa malinga ndi njira zinazake, ndipo kusintha kwa pointer ya mita yomwe ilipo kapena momwe babu ilili kumawonedwa kuti ayesere magetsi owongolera a chowongolera. Ngati magetsi sali mkati mwa 13.6 - 14.5V, zimasonyeza kuti chowongoleracho chili ndi vuto. Kawirikawiri, zowongolera zamagetsi zolumikizidwa sizingakonzedwe zikawonongeka ndipo zitha kusinthidwa zokha. Mukawasintha, ndikofunikira kusankha chowongolera choyenera chomwe chikugwirizana ndi choyambirira malinga ndi magetsi odziwika, polarity ya nthaka, ndi zina. Ma voltage ndi mitundu ya nthaka ya chowongolera ndi jenereta ziyeneranso kukhala zofanana.
Kuzindikira ma controller a gawo la injini kumakhala kovuta ndipo nthawi zambiri kumafuna kugwiritsa ntchito zida zaukadaulo zowunikira magalimoto. Kuwerenga ma code olakwika a injini, kusanthula deta ya gawo la camshaft, ndi zina zotero. Vuto likapezeka, kwa owongolera magawo oyendetsedwa ndi hydraulic, kungakhale kofunikira kuwona ngati dera la mafuta a hydraulic latsekedwa ndipo ngati mphete yotsekera yawonongeka; kwa owongolera oyendetsedwa ndi magetsi, ndikofunikira kuwona ngati dera la mota ndi lowongolera ndi labwinobwino. Nthawi zina, zigawo zowongolera magawo owonongeka ziyenera kusinthidwa.
Mfundo zazikulu pakusamalira ma modulators a magalimoto tsiku ndi tsiku
Kuti muchepetse kulephera kwa ma modulator a magalimoto, kukonza tsiku ndi tsiku ndikofunikira. Choyamba, kuwunika pafupipafupi kwa makina amagetsi a galimoto ndikofunikira kuti muwonetsetse kuti mawaya pakati pa jenereta ndi regulator ndi otetezeka, kupewa zolakwika monga kuyitanitsa kosakhazikika chifukwa cha mawaya otayirira. Kachiwiri, malinga ndi zofunikira za buku lowongolera galimoto, nthawi zonse sinthani mafuta a injini, zosefera mpweya, ndi zina zotero, kuti muwonetsetse kuti mkati mwa injini muli ukhondo komanso kuti malo ogwirira ntchito akhale abwino kwa regulator wa gawo. Kuphatikiza apo, mukasintha batire kapena jenereta, sankhani zinthu zomwe zikugwirizana ndi galimotoyo kuti mupewe kuwononga modulator chifukwa cha kusalingana kwa magetsi kapena mavuto ena.
Monga gawo lofunika kwambiri la makina amagetsi a galimoto, ma modulators a magalimoto sanganyalanyazidwe. Kumvetsetsa ntchito zawo, mawonekedwe a zolakwika, ndi njira zodziwira ndi kuthetsa mavuto kungathandize eni magalimoto kuzindikira ndi kuthetsa mavuto mwachangu, kuonetsetsa kuti galimotoyo ikugwira ntchito bwino komanso kukulitsa nthawi yake yogwira ntchito.
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.
