Abstract
A method and control module for controlling an engine includes a requested torque module that generates a requested torque and a turbo boost level module that determines a desired boost level based on the driver requested torque. The control module further includes a pulse determination module that determines a primary fuel injection pulsewidth and a secondary fuel injection pulsewidth based on the driver requested torque and the desired boost level and controls a first injection into the cylinder with the primary fuel injection pulsewidth and a second injection into the cylinder with the secondary fuel injection pulsewidth.
