Amir Torabi, Saleh Akbarzadeh, Mohammad Reza Salimpour

Journal of Mechanical Science and Technology > 2016 > 30 > 3 > 1295-1303

A considerable portion of the power loss in a valve train mechanism is due to the losses in the cam follower mechanism. The surface of cam and follower experience counterformal contact with a varying nature that makes it a difficult component in an engine to model. Transient contact geometry and entraining may cause the inlet boundary reversal and short lived cessation of entraining motion which can...
