Icamshaft yinxalenye yenjini yepiston. Umsebenzi wayo kukulawula ukuvulwa kwevalve kunye nesenzo sokuvala. Nangona i-camshaft ijikeleza kwisiqingatha sesantya se-crankshaft kwi-injini ye-stroke ezine (i-camshaft ijikeleza ngesantya esifanayo ne-crankshaft kwi-injini ye-stroke ephindwe kabini), i-camshaft idla ngokujikeleza ngesantya esiphezulu kwaye ifuna i-torque eninzi. . Ke ngoko, uyilo lwecamshaft lufuna amandla aphezulu kunye neemfuno zenkxaso. Ngokuqhelekileyo yenziwe nge-alloy high-quality okanye i-alloy steel. Uyilo lwecamshaft ludlala indima ebaluleke kakhulu kuyilo lwenjini kuba umthetho wokuhamba kwevalvu unxulumene namandla kunye neempawu zokusebenza kwenjini.
I-camshaft iphantsi kwemithwalo yempembelelo ngamaxesha. Uxinzelelo loqhagamshelwano phakathi kwe-CAM kunye ne-turtet likhulu kakhulu, kwaye isantya sokutyibilika esihambelanayo siphezulu kakhulu, ngoko ke ukunxiba kwendawo yokusebenza ye-CAM kunzima kakhulu. Ngenxa yale meko, ijenali ye-camshaft kunye ne-CAM yokusebenza komhlaba kufuneka ibe nokuchaneka okuphezulu komgangatho, uburhabaxa obuncinci bomgangatho kunye nokuqina okwaneleyo, kodwa kufuneka ibe nokuchasa okuphezulu kunye nokuthambisa okulungileyo.
IiCamshafts zihlala zenziwe kumgangatho ophezulu wekhabhoni okanye intsimbi yealloy, kodwa zinokuphoswa kwi-alloy okanye i-nodular cast iron. Indawo yokusebenza yejenali kunye neCAM igudiswe emva konyango lobushushu
