Zizindikiro za Nthawi Yolakwika kapena Yolakwika ya Valve Timing (VVT) Solenoid
Zamkatimu
Zizindikiro zodziwika bwino za VVT solenoid yoyipa zimaphatikizapo kuwala kwa injini ya Check Engine, mafuta oyipa a injini, kuyimitsa injini, komanso kutsika kwamafuta mafuta.
Kumayambiriro mpaka pakati pa zaka za m’ma 1960, zimphona zazikulu zamagalimoto za ku America Chrysler, Ford, ndi General Motors zinalamulira misewu ndi misewu ikuluikulu kudutsa dzikolo. Galimoto iliyonse yatsopano ikatulutsidwa, Atatu Akuluakulu adaphunzira zambiri za momwe injini imagwirira ntchito komanso momwe angasinthire mphamvu iliyonse yamahatchi kuti ituluke mu injini zawo posintha pamanja ma valve ndi nthawi yoyatsira. Chimodzi mwazotukuka kwambiri chinali chitukuko cha Variable Valve Timing (VVT), njira yatsopano yomwe idagwiritsa ntchito ukadaulo wapamwamba (panthawiyo) kuti upereke ma siginecha amagetsi osinthika kuchokera pamoto woyatsira kudzera pa solenoid yanthawi ya valve. Masiku ano, makina a VVT amapezeka m'magalimoto onse opanga omwe amagulitsidwa ku US.
Wopanga magalimoto aliyense ali ndi mawonekedwe ake apadera a VVT, koma ambiri amadalira valavu yosinthira nthawi ya solenoid kuti azitha kuyendetsa mafuta mu VVT ikayatsidwa. Dongosololi nthawi zambiri limatsegulidwa injini ikadzaza kwambiri. Zitsanzo zina za izi ndi monga pamene galimoto ikulemera kwambiri, kuyendetsa kukwera phiri, kapena pamene kuthamanga kumapititsidwa ndi throttle control. VVT solenoid ikayatsidwa, mafuta amawongolera kuti azipaka unyolo wanthawi ya valve ndi gulu la zida. Ngati solenoid ya VVT ikalephera kapena kutsekedwa, kusowa kwamafuta oyenera kungayambitse kuvala msanga kapena kulephera kwathunthu kwa unyolo wanthawi ndi zida.
Pali mavuto ena angapo omwe angachitike pamene VVT solenoid yatha kapena kusweka, zomwe zingayambitse kulephera kwathunthu kwa injini. Kuti muchepetse mwayi woti zinthu izi zichitike, nazi zizindikiro zingapo zomwe zingasonyeze vuto ndi VVT solenoid. Nazi zizindikiro zochepa za VVT solenoid yotha kapena yosweka.
1. Chongani Kuwala kwa injini kumabwera.
Popeza magalimoto amakono akulamulidwa ndi injini ulamuliro unit (ECU), pafupifupi zigawo zonse payekha amalamulidwa ndi ECU. Gawo limodzi likayamba kulephera, ECU imasunga nambala yamavuto yomwe imalola makina ogwiritsa ntchito scanner kudziwa kuti pali vuto. Kachidindo ikapangidwa, imawonetsa dalaivala powunikira chenjezo la malo enieni. Kuwala kofala kwambiri komwe kumabwera VVT solenoid ikalephera ndi kuwala kwa Injini.
Chifukwa chakuti wopanga galimoto aliyense amagwiritsa ntchito zizindikiro zosiyana, ndikofunika kwambiri kuti mwini galimotoyo alankhule ndi makina ovomerezeka a ASE kuti ayang'ane galimotoyo, kutsitsa kachidindo ndi chida cholondola chodziwira matenda, ndi kudziwa komwe kuli vuto. M'malo mwake, pali mitundu ingapo yamavuto a VVT solenoid kwa aliyense wopanga magalimoto. Wokonza makina akakhala ndi chidziwitso choyambirira ichi, akhoza kuyamba kuthetsa vuto lenileni.
2. Mafuta a injini ndi akuda
Ichi ndi chifukwa chachikulu kuposa chizindikiro. VVT solenoid imagwira ntchito bwino mafuta a injini akakhala oyera, opanda zinyalala, kapena ataya mafuta ake kapena mamasukidwe ake. Mafuta a injini akatsekedwa ndi zinyalala, dothi, kapena tinthu tating'ono takunja, amatha kutseka njira yochokera ku solenoid kupita ku unyolo wa VVT ndi zida. Ngati mafuta a injini yanu sanasinthidwe pa nthawi yake, amatha kuwononga VVT solenoid, dera la VVT, ndi sitima yamagetsi.
Kuti mupewe izi, onetsetsani kuti mwasintha mafuta a injini yanu malinga ndi malingaliro a wopanga magalimoto. Mafuta otsika amathanso kuyambitsa mavuto ndi VVT solenoid ndi zida zina zamakina anthawi.
3. Injini yosagwira ntchito
Nthawi zambiri, makina a VVT simagwira ntchito mpaka injiniyo ili pa RPM yapamwamba kapena itabweretsedwa pamalo onyamula, monga poyendetsa kukwera. Komabe, ngati VVT solenoid ndi cholakwika, n'zotheka kuti adzapereka owonjezera injini mafuta magiya VVT. Izi zitha kupangitsa kuti injini ikhale yosagwirizana, makamaka, kuthamanga kwa injini kumasinthasintha makinawo akayatsidwa. Ngati sichiyang'aniridwa mwachangu, izi zitha kupangitsa kuti zida zowonjezera za injini ziwonongeke msanga. Ngati injini yanu ili yosakhazikika pakugwira ntchito, onani makaniko wovomerezeka posachedwa.
4. Kuchepetsa kugwiritsa ntchito mafuta
Cholinga cha nthawi yosinthira ma valve ndikuwonetsetsa kuti ma valve amatsegula ndi kutseka pa nthawi yoyenera kuti injini ikhale yogwira ntchito komanso kuchepetsa kugwiritsa ntchito mafuta. VVT solenoid ikalephera, dongosolo lonselo likhoza kusokonezedwa, zomwe zingapangitse kuti ma valve olowa ndi otulutsa atsegule ndi kutseka nthawi yolakwika. Monga lamulo, izi zimabweretsa kuchepa kwakukulu kwamafuta.
Ngati muwona chenjezo lililonse lomwe lili pamwambapa la valavu yolephereka kapena yolakwika, funsani makaniko ovomerezeka a AvtoTachki ASE. Atha kuyang'ana galimoto yanu, m'malo mwa valve yosinthira nthawi ya solenoid ngati kuli kofunikira, ndikusunga galimoto kapena galimoto yanu ikuyenda bwino.
