I-Fuel fuel camshaft iyingxenye yenjini ye-piston.Umsebenzi wayo ukulawula isenzo sokuvula nokuvala i-valve.Yize i-camshaft esenjinini ene-STROKE ikwazi ukuzungeza engxenyeni yejubane le-crankshaft, ijubane layo lisephezulu kakhulu.Ngakho-ke, umklamo we-camshaft emandleni nokusekelwa kwezidingo kuphezulu kakhulu.Izinto zayo ngokuvamile ziyinsimbi ye-alloy yekhwalithi ephezulu noma i-alloy steel.Idizayini ye-camshaft idlala indima ebaluleke kakhulu ekwakhiweni kwenjini ngoba umthetho wokunyakaza kwamavalvu uhlobene namandla nezici zokusebenza kwenjini.
Umzimba oyinhloko we-camshaft iyinduku ye-cylindrical cishe ubude obufanayo ne-cylinder.Imbozwe ngamakhamera amaningi okushayela i-valve.I-Camshaft isekelwa ku-camshaft enembobo ye-camshaft yijenali ye-camshaft, ngakho-ke inombolo yejenali ye-camshaft iyisici esibalulekile esithinta ukuqina kokusekelwa kwe-camshaft.Uma ukuqina kwe-camshaft kunganele, ukuguqulwa kokugoba kuzokwenzeka ngesikhathi somsebenzi, okuzothinta isikhathi se-valve.
Izinhlangothi ze-camshaft zimise okweqanda.Yenzelwe ukuqinisekisa ukuthi i-cylinder iyangena futhi iyaphuma.Ukwengeza, uma kucatshangelwa ukuqina kwenjini kanye nokushelela kokusebenza, i-valve ayikwazi ukubangela umthelela omkhulu ngenxa yenqubo yokusheshisa nokunciphisa ekuvuleni nasekuvaleni isenzo.Uma kungenjalo, kuzodala ukugqokwa kwe-valve okungathi sína, ukwanda komsindo noma eminye imiphumela emibi.
I-camshaft ingaphansi kwemithelela yezikhathi ezithile.Ingcindezi yokuxhumana phakathi kwe-camshaft ne-tappet iphezulu kakhulu, futhi isivinini sokuslayida esihlobene siphezulu kakhulu.Ngaphezu kwalokho, ukugqokwa kwendawo yokusebenza ye-camshaft kubucayi kakhulu., Ngakolunye uhlangothi kuzoba nokunemba okuphezulu kobukhulu, ukuhwaqeka okuncane kwendawo kanye nokuqina okwanele bekukhona kujenali ye-camshaft kanye nendawo yokusebenza ye-CAM, ngakolunye uhlangothi, kuzoba khona ukumelana nokugqokwa okuphezulu. futhi ukuthambisa okuhle kwakukhona.Ngaphezu kwalokho, ama-camshafts avame ukwakhiwa ngensimbi yekhwalithi ephezulu ye-carbon steel noma i-alloy steel, futhi angakhishwa nge-alloy noma i-ductile iron.
