Abstract:Methods for improving the performance of the main diesel engines
of the 378-foot Coast Guard High Endurance Cutter have been investgated.
These engines are models FM3W8-l-/8 rated for 3600hp at
90QrDM. Present engine performance was evaluated through questionnaires
and interviews with cognizant Coast Guard personnel and visits
to selected cutters. In addition, operating records of the Coast
Guard and Colt Industries were reviewed. Limited -engine testing was
performed to verify data trends. We concluded that improvements in
engine performance can be made by converting these engines to a new
style turbocharger system, pistons, and injectors. Recommendations
are also made on methods to improve data taking in full-power trials
and engine trend analysis.
