Abstract
A controller may determine that a regeneration process associated with an engine of a machine is active. The controller may obtain, based on determining that the regeneration process is active, information concerning a speed of the engine, information concerning a load of the engine, and information concerning a fuel rate of the engine. The controller may select, based on the information concerning the speed of the engine, the information concerning the load of the engine, and the information concerning the fuel rate of the engine, a control process, of a plurality of control processes, to control an intake manifold absolute pressure (IMAP) of the engine to facilitate the regeneration process. The controller may cause, according to the selected control process, adjustment of one or more components of a variable geometry turbocharger (VGT) of the engine and an intake throttle valve (ITV) of the engine.
