Abstract
A power system for a work vehicle is provided and includes an intake arrangement configured to intake charge air; a fuel arrangement including 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 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 from the fuel arrangement with the charge air from the intake arrangement to generate mechanical power and exhaust gas; and an exhaust gas recirculation (EGR) arrangement configured to direct a portion of the exhaust gas back into the compression ignition engine. The fuel arrangement is arranged to selectively inject the second fuel into the EGR arrangement.
