Ukushaya kwenjini okungaqondakali
Ngaphambi kokuthenga imoto eke yasetshenziswa, kufanele unqume ukuthi ngabe udinga ukufaka esikhundleni seziphakamisi ze-hydraulic valve. Uma sisabela ngokushesha, izindleko zizoba phansi.
Izimoto ezisetshenzisiwe ngokuvamile zinebanga elingaphezu kwamakhilomitha angu-100. km futhi kukholakala ukuthi izinjini zabo zikaphethiloli zingamelana nokunye okuningi. Yiqiniso, ngaphambi kokuthenga kufanelekile ukunquma ukuthi abasabalalisi be-hydraulic badinga ukushintshwa.
Uma siphendula ngokushesha, izindleko zizoba phansi futhi ukunganaki kungaholela ekulungiseni okukhulu futhi, ngeshwa, izindleko eziphezulu. Iziphakamisi zamavalvu ezinama-hydraulic ngokuphawulekayo Izinjini eziningi zesimanje zisebenzisa lokho okubizwa ngama-hydraulic valve lifters, okwenza ukusebenza kwemoto kube lula futhi kungabizi. "src="https://d.motofakty.pl/art/3w/vd/81cmzwg0koo0ww848kwo0/447151cadd95a-d.310.jpg" align="right"> isevisi yemoto ethuthukisiwe. Kungenxa yabo ukuthi asikho isidingo sokulungisa ukucaciswa kwe-valve ngezikhathi ezithile. Isevisi yemoto iyashesha futhi ishibhile ngesikhathi esifanayo. I-pusher ifakwe phakathi kwe-camshaft ne-valve futhi umsebenzi wayo ukusetha kabusha ukudlala kwe-valve okubangelwa ukuguga kwezingxenye ezisebenzisanayo.
Ukuqina kwe-Pusher
Amafutha enjini ageleza kuma-tappets ngakho-ke azwela kakhulu izinga lamafutha asetshenzisiwe. Ikhwalithi ephansi noma ukukhetha okungalungile kungalimaza le nto enembayo nethambile ngokushesha okukhulu. Isimo esifanayo sizokwenzeka uma izikhawu phakathi kwezinguquko zikawoyela zanda kakhulu. Impilo yesevisi yama-pushers iyahlukahluka, kodwa kungacatshangwa ukuthi ngokwesilinganiso imayelana ne-150 km. Vele, akuvamile ukuthi ama-pushrods asebenze kahle ngisho nangemva kokugijima kwe-300 50. km, futhi kwenzeka ukuthi ngemuva kwezinkulungwane eziyi-XNUMX zizoba nelungelo lokushintshwa.
Ungawubona kanjani umonakalo?
Ukulimala kweziphakamisi zamavalvu kungase kuboniswe ngomsindo ovela eduze kwesembozo sevalvu. Lokhu kuwukungqongqoza okucacile nokwensimbi, isibonelo, esimweni sokucaciswa kwe-valve kakhulu. Esigabeni sokuqala sokungasebenzi kahle, abaphushayo benza umsindo ngemuva nje kokuqalisa injini, bese bezwakala njalo. Uma umsindo uphela nge-rpm ephakeme, kungase kube uphawu lokuthi ingcindezi ohlelweni lokuthambisa iphansi kakhulu. Ukushintsha i-pushrod eyodwa kuphela ngeke kusebenze kahle, njengoba kunzima kakhulu ukuthola eyonakele (ikakhulukazi uma kuyinjini engu-16-valve). Uma ama-pushers ebiza, khona-ke ngemva kokulalela ngokucophelela injini, angashintshwa kuphela, isibonelo, ku-cylinder eyodwa. Kodwa-ke, lapho ama-pushrods engabizi, kufanelekile ukuwashintsha wonke ngesikhathi esisodwa, ngoba impilo esele cishe izophela. Ngale ndlela, sizogwema izindleko zokusebenza eziphindaphindiwe ezingenasidingo. Izindleko zokushintshwa ziyahlukahluka kakhulu futhi zincike ekufinyeleleni kalula kwabaphusha kanye nenani labaphusha ngokwabo.
Umsindo we-timing drive awukona nje kuphela ukusola abaphushayo. Kungase futhi kubangelwe i-camshaft egugile noma ingcindezi yamafutha ephansi ebangelwa, isibonelo, ukukhetha okungalungile kwesihlungi samafutha (ukusetshenziswa kwamafutha kuphansi kakhulu).
Osebenzisa ama-pusher
Ompompi bama-hydraulic asetshenziswa ezinjini eziningi namuhla. Kodwa-ke, kukhona okuhlukile. Ngokwesiko, i-Honda ne-Toyota ayisebenzisi ukulawulwa kwamanzi, futhi kwa-VW sekunesikhathi eside bashintshela kumthetho onjalo kuzo zonke izinjini, njenge-Opel, i-Mercedes, i-BMW ne-Daewoo (ngaphandle kwe-Tico ne-Matiza).
Kuhlukile ngezinjini ezindala. Iningi lamayunithi anama-valve amane isilinda ngasinye ashintshwa ngogesi. Okuhlukile kukhona izinjini zeFord neNissan, lapho imvume ilawulwa ngezindlela zendabuko. Ezimotweni zaseFrance, kungacatshangwa ukuthi uma injini kaphethiloli ine-valve emibili, izikhala zilungiswa ngesandla, kanti ezine-valve - nge-hydraulically. Okufanayo kungacatshangwa ekukhathazekeni kwe-Fiat, nakuba kwezinye izimo kuhlukile.
Awekho ama-hydraulic pushers
Ukubethela i-valve ngokuzilungisela kulula futhi ngezinye izikhathi okudingayo nje i-feeler gauge, isikrufu esijwayelekile kanye ne-screwdriver. Ngakolunye uhlangothi, ezinjinini eziningi, ukulungisa imvume kuyinto engathi sína, edla isikhathi (kuze kufike emahoreni angu-8) futhi ibiza kakhulu ngokususa ibhande lesikhathi namashafu kanye nokushintshwa kwezinye izakhi. Izindleko zokulungiswa zisuka ku-30 kuye ku-500 PLN, kuye ngezinga lobunkimbinkimbi. Imvamisa yokulungiswa kwe-backlash iyahlukahluka kusuka ku-10 kuye ku-100 ayizinkulungwane. km. Endabeni yokufaka i-refueling ngegesi, kunconywa ukuthi uhlole i-backlash kaningi, ngoba ezinjini eziningi zegesi i-backlash iyancipha ngokushesha kakhulu. Futhi ukuntuleka kokudlala kubangela ukulahlekelwa amandla, futhi kungalimaza kakhulu injini.
