Ntchito ya valavu yowongolera kayendedwe ka mafuta a injini yamagalimoto
Valavu yowongolera kuyenda kwa mafuta a pampu yamafuta ya galimoto, yomwe nthawi zambiri imatchedwa valavu yoletsa kuthamanga kwa mafuta pampu yamafuta, imagwira ntchito makamaka yowongolera ndikuwongolera kuthamanga kwa mafuta kwakukulu mu dongosolo lopaka mafuta la injini, kuteteza kuwonongeka kwa zinthu monga pampu yamafuta, njira zamafuta, ndi zisindikizo chifukwa cha kuthamanga kwambiri.
Mfundo yeniyeni yogwirira ntchito ndi ntchito yake ndi iyi:
Kulamulira kuthamanga kwa mafuta: Liwiro la injini likakwera kapena kukhuthala kwa mafuta kukakwera, mafuta operekedwa ndi pampu yamafuta amawonjezeka, zomwe zimapangitsa kuti kuthamanga kwa mafuta munjira yayikulu yamafuta kukwere. Kapangidwe ka mkati mwa valavu yoletsa mafuta kamakhala ndi kasupe ndi pakati pa valavu. Kuthamanga kwa mafuta kukapitirira malire okhazikika a chitetezo, kuthamanga kwa mafuta kudzagonjetsa mphamvu ya kasupe, kukankhira pakati pa valavu, ndikulola mafuta ena kuyenda kudzera mu valavu yoletsa kubwerera ku doko lolowera la pampu yamafuta (mwachitsanzo, "kuchepetsa kuthamanga kwa mafuta"), potero kukhazikika kuthamanga kwa mafuta munjira yayikulu yamafuta mkati mwa malire oyenera.
Kuteteza chitetezo cha dongosolo: Kupanikizika kwambiri kwa mafuta kungayambitse kuphulika kwa fyuluta ya mafuta, kutuluka kwa mapaipi a mafuta, ma gaskets ophimba ma valve mu chipinda cha valve, kapena zomatira za mafuta kutsogolo ndi kumbuyo kwa crankshaft, ndi zina zotero. Valavu yoletsa, monga chipangizo chotetezera, imatha kuletsa zolakwika zotere ndikuwonetsetsa kuti dongosolo lopaka mafuta likugwira ntchito bwino kwa nthawi yayitali.
Palibe chowongolera chakunja chofunikira: Valavu iyi ndi kapangidwe ka makina kokha komwe kamakwaniritsa malamulo okhazikika kutengera kuthamanga kwa mafuta. Sikufuna kutenga nawo mbali kwa chipangizo chowongolera zamagetsi (ECU). Kapangidwe kake ndi kosavuta ndipo yankho lake ndi lachangu.
Tiyenera kudziwa kuti mu zipangizo zina, "valavu yowongolera kuyenda" nthawi zambiri imatanthauza zinthu zofanana mu chiwongolero kapena dongosolo la mafuta, pomwe mu dongosolo la pampu ya mafuta, mawu olondola kwambiri ndi "valavu yochepetsera" kapena "valavu yotetezera", yomwe ntchito yake yayikulu ndikuchepetsa kuthamanga kwa magazi m'malo mongowongolera kuyenda kwa magazi.
Kuwonongeka kwa valavu yamagetsi yowongolera kayendedwe ka mafuta (nthawi zambiri kutanthauza valavu yamagetsi yowongolera kuthamanga kwa mafuta kapena zinthu zina zofanana) kudzakhudza kwambiri magwiridwe antchito abwinobwino a galimoto. Sikoyenera kupitiriza kuyendetsa.
Valavu yamagetsi iyi ndi gawo lofunika kwambiri lolamulira makina opaka mafuta a injini, lomwe limayang'anira kuthamanga kwa mafuta ndi kuyenda kwawo kuti liwonetsetse kuti gawo lililonse la injini limalandira mafuta okwanira. Likawonongeka, limayambitsa kuthamanga kwa mafuta kosazolowereka, motero limayambitsa mavuto angapo a unyolo.
Zotsatira zazikulu zikuphatikizapo:
Mafuta osakwanira a injini: Kuthamanga kwa mafuta kochepa kapena kosakhazikika kumapangitsa kuti ziwalo zamkati mwa injini (monga ma camshaft, ma valve mechanisms, ma bearing, ndi zina zotero) zisalandire mafuta okwanira, zomwe zimapangitsa kuti mafuta awonongeke mofulumira.
Phokoso losazolowereka la injini ndi kugwedezeka: Mafuta osakwanira angayambitse phokoso lodziwika bwino la injini (monga "kugundana") komanso kutsagana ndi kusakhazikika kapena kugwedezeka poyendetsa.
Kutaya mphamvu ndi kufooka kwa mphamvu: Kwa mitundu ina, valavu yamagetsi yowongolera kuthamanga kwa mafuta imalumikizidwa ndi makina osinthira nthawi yamagetsi (VVT). Ikawonongeka, imayambitsa nthawi yolakwika yamagetsi, zomwe zimapangitsa kuti mphamvu ituluke komanso kuti ifulumire pang'onopang'ono.
Chiwopsezo cha kutentha kwambiri kwa injini: Mafuta samangopatsa mafuta okha komanso amatenga nawo mbali pakuchotsa kutentha. Kuyenda kosazolowereka kungakhudze momwe kutentha kwa injini kumagwirira ntchito, zomwe zimawonjezera chiopsezo cha kutentha kwambiri.
Malire a chitetezo cha injini yokha: ECU (gawo lowongolera injini) la magalimoto amakono limayambitsa njira yotetezera ikazindikira kuthamanga kwa mafuta kosazolowereka, kuchepetsa liwiro la injini ndi mphamvu kuti isawonongeke kwambiri. Pakadali pano, galimotoyo ikhoza "kutsika" ndikuchepetsa magwiridwe antchito.
Kuwonongeka kwakukulu kwa injini: Kuyendetsa galimoto kwa nthawi yayitali ndi valavu yamagetsi yowonongeka kungayambitse kugoba kwa silinda, kugwidwa ndi ma bearing, ndi kuwonongeka kwina kosasinthika kwa injini. Mtengo wokonzanso ndi wokwera kwambiri. Malangizo:
Imani nthawi yomweyo kuti mukayang'ane: Ngati dashboard ikuwonetsa nyali yochenjeza kuthamanga kwa mafuta, nyali yolakwika ya injini ikayaka, kapena ngati mukumva kutaya mphamvu kwakukulu kapena phokoso losazolowereka, muyenera kuyimitsa galimotoyo mosamala.
Lumikizanani ndi katswiri wokonza galimoto: Musayese kuyendetsa galimoto mokakamiza. M'malo mwake, funsani katswiri wokonza galimoto kuti akuthandizeni kudziwa ngati ndi vuto la valavu yamagetsi ndipo muisinthe nthawi yomweyo.
Kukonza nthawi zonse: Ndikofunikira kuyang'ana makina oyendetsera mafuta pamtunda wa makilomita 20,000 aliwonse kapena kuposerapo ndikugwiritsa ntchito mafuta a injini abwino kwambiri kuti muchepetse chiopsezo cha kusonkhana kwa mpweya ndi kutsekeka, motero kukulitsa moyo wa valavu yamagetsi.
Pomaliza, valavu yamagetsi yowongolera kayendedwe ka mafuta ikawonongeka, sikuti kuyendetsa galimoto kokha kudzachepa kwambiri, komanso padzakhala chiopsezo chachikulu chachitetezo. Muyenera kusiya kuyendetsa galimoto nthawi yomweyo ndikuchita kukonza.
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.
