Abstract
A computer-implemented method can include receiving a contact point path between a rocker arm pad and a valve tip. The method can include adjusting the contact point path to obtain a modified contact point path that satisfies a design objective of decreased valve tip wear or decreased valve tick. The method can include determining and outputting a custom contour for the rocker arm pad and the camshaft lobe based on the modified contact point path. The custom contoured camshaft lobe can companion with the custom contoured rocker arm pad to produce the modified contact point path for the specified design objective.
