Abstract:
There is described a system and method for filling an engine fuel manifold. An adaptive filling function is used to determine a flow rate at which fuel is to be delivered to the fuel manifold. The filling function receives as an input a present measurement of the engine's speed and computes the flow rate accordingly. The fuel manifold may then be filled according to the computed flow rate so as to match the engine's speed. Appropriate fuel/air ration conditions can therefore be achieved for successful engine start.
