Kodi mfundo ya valavu yamagalimoto ndi chiyani?
Ntchito yayikulu ya valavu yotulutsa galimoto ndikuwongolera mpweya wotuluka mu silinda kuonetsetsa kuti mpweya wotuluka ukayaka utha kutulutsidwa bwino, kuti pakhale mpweya wabwino ndi kusakaniza kwamafuta, kuti mupitirize kuyaka kosalekeza. cha injini.
Mfundo yogwirira ntchito ya valavu yotulutsa mpweya m'galimoto imatengera mikwingwirima inayi ya injini: kudya, kuponderezana, kugwira ntchito ndi kutopa. Panthawi yotulutsa mpweya, pisitoni imayenda m'mwamba ndipo valavu yotulutsa mpweya imatsegulidwa, zomwe zimapangitsa kuti mpweya utuluke mu silinda. Kutsegula ndi kutseka kwa valve yotulutsa mpweya kumayendetsedwa ndi camshaft, ndipo mawonekedwe a CAM pa camshaft amatsimikizira nthawi yotsegulira ndi nthawi ya valve yotulutsa mpweya. Makamaka, valavu yotulutsa mpweya nthawi zambiri imakhala ndi valavu, mpando, kasupe, ndi tsinde. Valavu imakhala yotsekedwa ndi machitidwe a kasupe mpaka CAM pa camshaft ikukankhira tsinde ndikugonjetsa mphamvu ya masika kuti itsegule valve. CAM ya camshaft ikatha, kasupe amatseka valavu mwachangu, kuwonetsetsa kuti mpweya wotuluka subwerera.
Kukhathamiritsa ndi kukonza ma valve otulutsa mpweya Potengera ukadaulo wosinthira ma valve, akatswiri opanga magalimoto amakono amasintha nthawi yotsegulira ndi kutalika kwa valavu yotulutsa mpweya molingana ndi kuchuluka kwa injini ndi liwiro kuti zithandizire kuyaka bwino komanso kuchepetsa mpweya. Kuphatikiza apo, injini zina zogwira ntchito kwambiri zimakhala ndi mavavu ambiri okhala ndi mavavu angapo olowera komanso otulutsa mpweya pa silinda kuti awonjezere kuthamanga kwa mpweya ndikuwongolera kuyaka bwino. Kusamalira nthawi zonse ndi kuyang'anitsitsa valavu yotulutsa mpweya kungatsimikizire kuti ikugwira ntchito bwino, kuphatikizapo kuyang'ana valavu ndi kuvala kwa mpando, kusintha ziwalo zowonongeka, ndi kusintha chilolezo cha valve.
Ntchito yayikulu yotulutsa ma valve agalimoto imaphatikizapo zinthu izi:
Chepetsani kudalira ma brake a service : valavu yotulutsa mpweya imatha kuchepetsa kwambiri kudalira mabuleki akuyendetsa galimoto, potero kuchepetsa kuvala kwa nsapato za brake kapena ma disks, ndikupewa kuopsa kwa chitetezo chomwe chimabwera chifukwa cha kutenthedwa kwa mabuleki mosalekeza.
Dongosolo lokhazikika la turbocharging : Valavu yotulutsa mpweya imagwira ntchito yofunika kwambiri pamakina a turbocharging, omwe amatha kukhazika mtima pansi ndikuwonetsetsa kuti injini ndi turbocharger zikuyenda bwino. Powongolera kuthamanga kwa mpweya wotuluka m'mbuyo, kutulutsa kwa valve kumakulitsa magwiridwe antchito a injini, makamaka pakatikati mpaka pa RPM yayikulu.
Control exhaust sound : Chipangizo chotulutsa valavu chimatha kuwongolera kukula kwa mafunde otulutsa mpweya ndikusintha phokoso la chitoliro chotulutsa potsegula ndi kutseka valavu. Vavu ikatsekedwa, phokoso lotulutsa mpweya ndi laling'ono, loyenera kugwiritsidwa ntchito pamalo opanda phokoso; Vavu ikatsegulidwa, phokoso lotulutsa mpweya limawonjezeka, mofanana ndi phokoso la galimoto yamasewera.
Ubwino wa chilengedwe : mpweya wotulutsa ma valve pobwezeretsanso pang'ono mpweya wotayirira mumoto wa silinda, kuchepetsa kutentha kwakuya, motero kulepheretsa kupanga NOx, kuchepetsa NOx zomwe zili mu mpweya wotulutsa mpweya, kuthandizira kuteteza chilengedwe.
Njira zosiyanasiyana zowongolera: Njira zowongolera ma valve ndizosiyanasiyana, zomwe zitha kuzindikirika ndi chiwongolero chakutali, APP yam'manja yam'manja kapena kuwongolera liwiro. Mukamagwiritsa ntchito chiwongolero chakutali, ingodinani batani lotseguka, chizindikiro chopanda zingwe chidzaperekedwa kwa wowongolera valavu, ndipo woyang'anira adzayang'anira valavu kuti atsegule atalandira lamulo.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina pa thndi site!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
