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
The rocker arm is the lever that in a controled fation moves the voulve up and down. When the engine turns it pushes the push rod up which makes the rocker arm act as a sea saw so when the push rod pushes one side up the other goes down which opens the voulve —Preceding unsigned comment added by 220.127.116.11 (talk) 04:14, 13 November 2009 (UTC)
