Nres CamShafts yuav tsum tau hloov rau ntau yam. Firstly, hnav thiab dhau los ntawm lub zog yog ib qho laj thawj. Thaum lub sijhawm ua haujlwm ib txwm, cov camshaft rotates thiab sib cuam tshuam nrog lwm cov khoom xws li khau muag thiab chais. Lub sijhawm dhau los, kev sib txhuam sib txhuam thiab cov neeg kho tshuab ua rau hnav rau cov camshaft nto. Qhov hnav no tuaj yeem ua rau tsis sib luag ntawm kev faib tawm, txo qhov chaw nres tsheb thiab nce qib braking. Thib ob, puas yuav tshwm sim. Sab nraud cuam tshuam los yog tsis muaj kev cuam tshuam yuav ua rau camshaft kom tawg lossis tawg. Lub camshaft puas ua haujlwm tsis tau ua haujlwm zoo, uas ua rau muaj kev phom sij muaj kev nyab xeeb loj. Qhov thib peb, cov khoom qaug zog yog lwm yam. Vim tias cov chaw thau khoom thiab kev thauj khoom ntawm lub zog quab yuam, cov khoom siv ntawm camshaft yuav muaj kev qaug zog. Thaum qaug zog tshwm sim, cov khoom siv mechanories ntawm cov khoom hloov, thiab nws yuav tsis muaj peev xwm tiv taus rau cov rog uas xav tau lawm, ua rau tsis ua haujlwm. Tsis tas li ntawd, yog tias muaj teeb meem nrog lub tshuab roj carration, lub camshaft kuj yuav tsis tau lubricated zoo. Qhov no yuav ua kom kev sib txhuam thiab cua sov, ua kom nrawm dua cov hnav thiab puas ntawm camshaft. Txhawm rau kom ntseeg tau tias qhov kev ua haujlwm ib txwm muaj kev nyab xeeb thiab kev nyab xeeb ntawm kev tsav tsheb, nws yog qhov tsim nyog los kuaj xyuas cov mob ntawm lub camshaft thiab hloov nws raws li cov teeb meem pom.
