Summary:

An overhead camshaft valve train system with center pivot rocker has been analyzed. Considering the valve train as a rigid body and using the concepts of differential geometry and coordinate transformation, we can find the mathematical formulas of sufficient and necessary conditions to generate a cam profile.A valve train dynamic test rig was set up to investigate the relationship between valve motion and cam profile. The valve dynamic characteristics were also studied. Valve lift was measured by a LVDT, and valve train dynamic stress was monitored by a strain gage mounted on the rocker arm. Valve noise was measured by a microphone located near the valve seat. And, the relationship between valve noise and cam profile has been investigated
