Work vehicle low cetane power system with external to cylinder compression ignition assistance

A work vehicle, comprising:

• a chassis;
• a drive assembly supported on the chassis;
• a power system supported on the chassis and configured to power the drive assembly, the power system comprising:
• 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;
• a 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 one or more auto-ignition assistance modes, 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;
• wherein the compression ignition assistance apparatus includes an electric compressor that also forms part of the intake arrangement;
• wherein, in an auto-ignition second assistance mode of the one or more auto-ignition assistance modes, the controller is configured to command activation of the compression ignition assistance apparatus such that the electric compressor compresses at least a portion of the charge air;
• and
• wherein, in the nominal mode, the controller is configured to command or maintain deactivation of the electric compressor.
