1. A power system for a work vehicle, comprising:
an intake arrangement configured to intake charge air;
a fuel arrangement including a single fuel tank configured to store a low carbon fuel blend of multiple fuels as a single fuel source;
an engine including a plurality of piston-cylinder sets configured to receive, ignite, and combust a mixture of the charge air and the low carbon fuel blend;
an exhaust arrangement positioned downstream to receive exhaust from the engine during combustion of the low carbon fuel blend;
an exhaust sensor positioned at or proximate to the exhaust arrangement; and
a controller coupled to the exhaust sensor, the intake arrangement, the fuel arrangement, and the engine and configured to:
determine an initial indication of a composition of the low carbon fuel blend;
implement operating parameters with feedforward adjustments based on the initial indication of the composition of the low carbon fuel blend;
receive feedback from the exhaust sensor regarding operational conditions; and
adjust the operating parameters based on the feedback from the exhaust sensor.
