A method of controlling an engine having a mechanically driven supercharger supplying a flow of air to the engine includes defining a steady state operating condition in which the engine normally operates within efficiently. An engine parameter is monitored to determine if the engine is operating within the steady state operating condition, or outside the steady state operating condition in a transient operating condition. If the engine is operating outside the steady state operating condition in the transient operating condition, the flow of air from the supercharger is adjusted to maintain a fuel/air mixture to within a pre-determined ratio prior to increasing a fuel injection rate to the engine to minimize soot emissions from the engine during operation of the engine in the transient operating condition. |
