Abstract

See full text

An engine assembly includes an internal combustion engine with an engine block having at least one cylinder and at least one piston moveable within the at least one cylinder. A crankshaft is moveable to define a plurality of crank angles (CA) from a bore axis defined by the cylinder to a crank axis defined by the crankshaft. A controller is operatively connected to the internal combustion engine and configured to receive a torque request (TR). The controller is programmed to determine a desired combustion phasing (CAd) for controlling a torque output of the internal combustion engine. The desired combustion phasing is based at least partially on the torque request (TR) and a pressure-volume (PV) diagram of the at least one cylinder.
