There are many factors that contribute the rocker arm design, and many more constraints that effect the final outcome of such a design. Sub topics of valve wear, socket wear, heat and lubrication issues, stability, stiffness, mass and inertia, dynamic response, wear surface treatment, pivot and head geometry and many more are topics that need to be mentioned.
How it works
