Abstract
An electrically powered fuel pump in an electronic returnless fuel delivery system for an internal combustion engine is controlled during transient engine operating conditions. A controller senses an operating parameter to infer whether a transient engine operating condition exists. Then, the controller generates an estimate of a fuel pump correction signal based on this inference. The correction signal is generally sufficient to cause the fuel pump to respond to the transient condition, by supplying a generally correct amount of fuel, prior to the engine requiring a change in fuel quantity.
