Beschreibung
Zusammenfassung:	A power system for a work vehicle, includes an intake arrangement configured to intake charge air; a fuel arrangement configured to provide at least one fuel; a compression ignition engine including a plurality of piston-cylinder sets configured to receive, ignite, and combust the at least one fuel from the fuel arrangement and intake gas that includes the charge air from the intake arrangement to generate mechanical power and exhaust gas; at least one compression ignition assistance apparatus associated with at least one of the intake arrangement and the fuel arrangement; and a controller coupled to command the compression ignition assistance apparatus, the intake arrangement, and the fuel arrangement such that, in an enhancement mode, the controller commands activation of the compression ignition assistance apparatus; and in a nominal mode, the controller commands or maintains deactivation of the compression ignition assistance apparatus.
