Abstract
An internal combustion engine comprising valve sets through which combustion air enters a cylinder is mixed with fuel for combustion therein and through which products of combustion exit. A valve train assembly comprises a drive rocker arm, including a first, proximal end in contact with a rotatable camshaft and a second, distal end in contact with a valve shaft of a first valve of a valve set and a driven rocker arm including a first, proximal end in contact with the drive rocker arm at a location that is adjacent to the first, proximal end thereof and a second, distal end in contact with a valve shaft of a second valve of a valve set. The drive rocker arm and the driven rocker arm operate to move the valves reciprocally from a closed to an open position.
