  • Work vehicle power system with low carbon fuel blends
    Patent number: 12270354
    Abstract: A power system for a work vehicle includes an intake arrangement for intake of charge air; a fuel arrangement including a fuel tank storing a low carbon fuel blend; an engine 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; at least one exhaust sensor positioned at or proximate to the exhaust arrangement; and a controller. The controller is configured to receive 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 at least one exhaust sensor regarding operational conditions; and adjust the operating parameters based on the feedback.
