Abstract
A system and method are provided for avoiding transient compressor surge in a turbocharged internal combustion engine. The system includes a control circuit responsive to at least one engine operating parameter to determine a minimum fueling limit that is generally higher under certain engine operating conditions than the default engine fueling value. Under such conditions, the minimum fueling limit is used to establish a lower limit of fuel supplied to the engine in order to avoid turbocharger transient compresser surge conditions. In one embodiment, the at least one engine operating parameter includes intake manifold air pressure, and in an alternative embodiment, the at least one engine operating parameter further includes intake manifold air temperature. In either case, the at least one engine operating parameter also preferably includes engine speed.
