Work vehicle dual fuel compression ignition power system

A work vehicle, comprising:

• a chassis;
• a drive assembly supported on the chassis;
• and
• a power system supported on the chassis and configured to power the drive assembly, the power system comprising:
• an intake manifold configured to intake charge air;
• a first fuel tank configured to store a first fuel and a second fuel tank configured to store a second fuel;
• a compression ignition engine including a fuel injector and a plurality of piston-cylinder sets configured to receive, ignite, and combust the first fuel, the second fuel, or a combination of the first and second fuels with the charge air from the intake manifold to generate mechanical power and exhaust gas;
• an exhaust gas recirculation (EGR) circuit configured to direct a portion of the exhaust gas back into the compression ignition engine and having an EGR injector configured to selectively inject the second fuel from the second fuel tank into the EGR circuit;
• and
• a controller having electronic processing and memory architecture wherein, in a dual fuel control mode, the controller commands the fuel injector such that the first fuel is directed into the compression ignition engine and commands the EGR injector such that the second fuel, and not the first fuel, is additionally directed into the compression ignition engine via the EGR circuit.
