I-camshaft iyingxenye yenjini yePiston. Umsebenzi wayo ukulawula isenzo se-valve ukuvula nokuvala. Yize i-camshaft ijikeleza ngesigamu sejubane le-crankshaft enjini enama-stroke amane (i-camshaft ijikeleza ngejubane elifanayo ne-crankshaft enjini eyodwa), i-camshaft ivame ukujikeleza ngesivinini esikhulu futhi idinga i-torque eningi. Ngakho-ke, ukuklanywa kwe-camshaft kudinga amandla aphezulu nezidingo zokusekelwa. Imvamisa yenziwa nge-alloy ephezulu ye-alloy noma i-alloy. Idizayini ye-camshaft idlala indima ebaluleke kakhulu ekwakhiweni kwenjini ngoba umthetho we-valve Movement uhlobene nezimpawu kanye nokusebenza kwenjini.
I-camshaft ifakwa ngaphansi kwemithamo yesikhathi esizayo. Ukucindezelwa kokuxhumana phakathi kwe-cam ne-turtet kukhulu kakhulu, futhi ijubane elihlobene nesihlobo liphezulu kakhulu, ngakho-ke ukugqokwa kwendawo yokusebenza ye-cam kubaluleke kakhulu. Ngenxa yalesi simo, iphephabhuku le-camshaft kanye ne-cam ukusebenza komhlaba kufanele kube nokunemba okuphezulu okuphezulu, ubulukhuni obuncane bendawo kanye nokuqina okwanele, kepha futhi kufanele kube nokuphikiswa okuphezulu nokuthambisa okuhle.
Ama-Camshafts ajwayele ukwakhiwa kusuka kukhabhoni esezingeni eliphakeme noma ngensimbi, kepha angaphonswa futhi kwinsimbi ye-alloy noma ye-nodular. Indawo esebenzayo yejenali ne-cam iboshwe ngemuva kokwelashwa okushisa
