Kodi chodulira magalimoto n'chiyani?
Chosinthira gawo la magalimoto, chomwe nthawi zambiri chimatanthauza chosinthira gawo mu dongosolo la nthawi ya valve yosinthika (VVT), ndi gawo lofunikira kwambiri mu njira yoyendetsera ma valve a injini. Chimagwiritsidwa ntchito kusintha nthawi yotsegulira ndi kutseka ma valve olowa kapena otulutsa mpweya kuti akwaniritse bwino magwiridwe antchito a injini, kusunga mafuta, komanso kuchuluka kwa mpweya wotuluka m'malo osiyanasiyana ogwirira ntchito.
Ntchito yake yaikulu ndikusintha ngodya ya gawo pakati pa camshaft ndi crankshaft kutengera momwe zinthu zilili nthawi yeniyeni monga liwiro la injini, katundu, ndi kutentha, motero zimathandiza nthawi yosinthasintha ya valve. Ma injini okhala ndi nthawi yokhazikika ya valve sangathe kulinganiza torque yothamanga pang'ono ndi mphamvu yothamanga kwambiri, pomwe gawo losinthira, kudzera mu kusintha kwanzeru, limalola injini kukwaniritsa bwino kwambiri intake ndi exhaust m'malo osiyanasiyana.
Kufotokozera mwachidule mfundo yogwirira ntchito
Chosinthira gawo nthawi zambiri chimayikidwa kutsogolo kwa camshaft ndikulumikizidwa ku unyolo wa nthawi kapena pulley. Kapangidwe kake kamakhala ndi rotor yolumikizidwa mwamphamvu ku camshaft ndi stator yolumikizidwa ku pulley ya nthawi. Mabowo angapo amafuta otsekedwa amapangidwa pakati pa rotor ndi stator.
Chosinthira gawo la hydraulic (chofunika kwambiri): Mafuta a injini, pansi pa kupanikizika kwa pampu ya mafuta, amaperekedwa molondola ku chipinda chotsogola kapena chobwerera m'mbuyo cha chosinthira gawo kudzera mu valavu yowongolera mafuta (valavu ya OCV). Mwa kulamulira kuthamanga kwa mafuta, rotor imazungulira poyerekeza ndi stator, motero imasintha gawo la camshaft. Mwachitsanzo, kupereka mafuta ku chipinda chotsogola kungapangitse valavu kutsegulidwa msanga kuti iwonjezere mphamvu yothamanga pang'ono; kupereka mafuta ku chipinda chobwerera m'mbuyo kungathe kuchedwetsa kutseguka kwa valavu kuti iwonjezere mphamvu yothamanga kwambiri.
Chosinthira gawo lamagetsi (ukadaulo watsopano): Mwachitsanzo, chosinthira gawo lamagetsi chomwe chinapangidwa ndi LuK chimagwiritsa ntchito kapangidwe ka makina koyendetsedwa ndi mota kokhala ndi ma axis atatu, komwe kamalumikiza mwachindunji camshaft, pulley, ndi mota. Mwa kuwongolera bwino liwiro la mota, kuzungulira pakati pa camshaft ndi pulley kumachitika, potero kusintha nthawi ya valavu. Kapangidwe kameneka sikadalira kuthamanga kwa mafuta a injini, kali ndi liwiro loyankha mwachangu, kulondola kwambiri, ndipo sikakhudzidwa ndi kukhuthala kwa mafuta a injini kutentha kochepa.
Ubwino waukulu
• Wonjezerani mphamvu yotulutsa: Konzani bwino ngodya ya valve yomwe imadutsana ndi liwiro lalikulu la injini, onjezerani kuchuluka kwa mphamvu yolowa, ndikuwonjezera mphamvu ya injini.
• Konzani mafuta osawononga: Pezani mphamvu ya Miller cycle pochedwetsa kutseka kwa valavu yolowera pa katundu wochepa, kuchepetsa kutayika kwa kupompa.
• Kuchepetsa mpweya woipa: Kuyaka kwathunthu kumachepetsa kupanga mpweya woipa (monga CO, NOx, ndi HC).
• Kulimbitsa kusinthasintha: Makamaka chosinthira gawo lamagetsi, chimasinthasintha kwambiri kutentha kwa injini ndi momwe imagwirira ntchito.
Kumvetsetsa kusamvetsetsana komwe kumachitika kawirikawiri
• Sensa ya gawo ≠: Sensa ya gawo ndi actuator, yomwe imayang'anira "kusintha"; pomwe sensa ya gawo (monga sensa ya malo a camshaft) ndi njira yodziwira, yomwe imayang'anira "malo enieni a camshaft ndikubwezera chizindikiro ku unit yowongolera injini (ECU) kuti ipange chowongolera chotsekedwa.
• Phase shifter ≠ camshaft variable phase controller: Yomalizayi ndi mawu omwe amagwiritsidwa ntchito ndi makampani monga Audi pa njira yawo yowongolera makina a VVT, ndipo gawo lake lalikulu la actuator ndi phase shifter.
Mwachidule, chosinthira gawo la magalimoto ndi chimodzi mwa ukadaulo wofunikira kwambiri wa injini zamakono kuti zigwire ntchito bwino, zoyera, komanso zogwira ntchito bwino. Kukula kwake kukusintha kuchoka pa mtundu wa hydraulic wachikhalidwe kupita ku mtundu wamagetsi wolondola komanso wodalirika.
Mu gawo la magalimoto, mawu oti "gawo losinthira" nthawi zambiri amatanthauza zigawo ziwiri zosiyana zogwirira ntchito, ndipo ntchito zawo zenizeni zimadalira makina omwe amagwiritsidwa ntchito.
• Chosinthira gawo la VVT (dongosolo la nthawi ya valve yosinthika): Ichi ndi gawo lofunika kwambiri mu dongosolo loyendetsera injini. Ntchito yake yayikulu ndikusintha gawo lozungulira la camshaft kutengera momwe injini imagwirira ntchito nthawi yeniyeni (monga liwiro ndi katundu). Mwa kusintha nthawi yotsegulira ndi kutseka ma valve olowetsa ndi/kapena otulutsa, imatha kukonza bwino momwe ilowa ndi njira yoyaka mu silinda, kukwaniritsa zotsatira zowonjezera mphamvu ya injini, kukonza mafuta osawononga, komanso kuchepetsa kutulutsa utsi. Woyang'anira dongosolo la mphamvu zamagalimoto (woyang'anira magetsi): Gawoli lili ndi udindo wowunikira ndikuwongolera mphamvu yotulutsa ya jenereta yagalimoto. Chifukwa cha kusintha kwa liwiro la injini, liwiro la jenereta limasinthasintha, zomwe zimapangitsa kuti magetsi otulutsa asakhazikike. Woyang'anira magetsi amawongolera mphamvu yamaginito mkati mwa jenereta kuti atsimikizire kuti magetsi otulutsa amakhalabe olimba pamtengo wovomerezeka (nthawi zambiri pafupifupi 14.0V). Izi zimateteza bwino zida zamagetsi zomwe zili m'bwalo ku kusinthasintha kwa magetsi ndipo zili ndi ntchito zoletsa mphamvu yochaja kwambiri ndikudula mphamvu yobwerera (kubwerera m'mbuyo) kuti ateteze batri ndi jenereta.
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.
