Abstract
A method for improving the transient response of a multi-port fuel injection system wherein the delivery of a pulse to an injector is fragmented into a variable number of pulse fragments and the delivery of the pulse fragments to the injector is spaced throughout a respective fueling window. The magnitude and delivery angle of each of the pulse fragments is variable and depends upon the current engine operating conditions. Calculations of the magnitude of each pulse fragment are based upon a constantly recalculated total pulse width.
