Abstract
A dual fuel system includes a fuel injector having a fuel pressurization plunger, and a fueling control unit structured to determine a fuel bulk modulus term based upon a volume change value (dV) and a pressure change value (dP) for a fuel pressurized in the fuel injector. The fueling control unit is further structured to determine fuel injector control commands by way of map lookups on fueling maps selected on the basis of the fuel bulk modulus term. Related apparatus and methodology are also disclosed.
