Abstract
An internal combustion engine fuel system applies injection control pressure to fuel injectors () to force fuel into combustion chambers (). A processor of a control system () develops data values for injection control pressure set-point (ICPCT13) representing desired injection control pressure and evaluates () the injection control pressure set-point data values for compliance with an allowable dynamic range defined by a data value for a minimum dynamic limit correlated with engine speed (N) from a function generator () and a data value for a maximum dynamic limit correlated with engine temperature (EOT) from a function generator (). The processor limits the data value of desired injection control pressure that is subsequently processed to control injection control pressure applied by the fuel system to the fuel injectors to the allowable dynamic range.
