Variable valve actuation apparatus, system, and method

A method comprising:

• coupling a double nested camshaft with a crankshaft of an internal combustion engine;
• engaging a first cam follower member of a cam follower with a first cam lobe and a second cam follower member with a second cam lobe;
• and
• fastening one end of a rocker arm to the cam follower.

An apparatus comprising:

• a rocker arm operable to be used in a variable valve actuation engine;
• a cam shaft having a variable first lobe and a variable second lobe;
• and
• means for following the variable first lobe and the variable second lobe, the means coupled to an end of the rocker arm.

A method comprising:

• rotating a cam shaft having an independently variable first lobe and an independently variable second lobe;
• periodically engaging the variable first lobe with a first member of a cam follower;
• substantially engaging the variable second lobe with a second member of the cam follower;
• pivoting the cam follower about a rocker;
• and
• rocking the rocker to actuate a valve.
