Abstract: The device consists of a mechanism to place netwrap over the edge of a cylindrical bale that is created in a variable/fixed baling chamber of an agricultural round baler. The invention consists of a netwrap delivery system having of a pair of arms pivotally affixed to the outside of the baling chamber sidewalls. Also attached to the arms is an assembly frame. An actuator controls the pivoting motion of the delivery system inserting the netwrap between the stationary dimple roll and the pivot roll of the sledge assembly. Positioned outside the sidewall and between the outer frame member is a transition area. The netwrap is inserted between the stationary dimple roll and the pivot roll as well as into the transition area. Because the width of the delivery assembly is wider than that of the cylindrical bale, a portion of the netwrap is inserted over the edge by use of the transition area.

Abstract: A method for controlling an engine having multiple banks with separate catalysts is described. In particular, coordinate lean and rich operation between the banks is utilized. However, termination of rich operation may be different between the banks to prevent breakthrough of rich exhaust gasses due to lack of stored oxidants.

This minimizes breakthrough of emissions, while at the same time minimizing a torque imbalance between the cylinder banks. In particular, the torque imbalance can be further minimized by retarding ignition timing on the rich bank while the other operates near stoichiometry.
