A system and method of inducing an operational response change in an operating direct-injection internal combustion engine is provided such that the engine includes a cylinder into which liquid fuel injection is directly performed. The method starts by operating the direct-injection engine using a start of injection (SOI) protocol. At some point during operation, it is determined that a change is desired for a first parameter of engine operation that is at least partially a function of a charge provided to the cylinder (such as the torque output). In response an operational response in the engine is induced by altering the SOI protocol via a first SOI alteration that alters the volumetric efficiency of the cylinder and changes the first parameter.
A method of operating an internal combustion engine having an intake manifold fluidly coupled to multiple cylinders including a first cylinder and a second cylinder, the method comprising:
An injection control system of an internal combustion engine, the system comprising:
