Development of Diesel Engine Diagnostics for U.S. Coast Guard Cutters.
Abstract
This program involved an investigation of techniques to perform engine fuel diagnosis on the large medium-speed diesel engines used as main propulsion power plants in medium- and high-endurance Coast Guard cutters. Two engine diagnostic parameters were defined and selected as the parameters of interest. They were: (1) Instantaneous Crankshaft Angular Velocity (ICAV), which directly relates to the developed power contribution for each cylinder; and (2) Dynamic Crankcase Pressure (PKD), which relates to the amount of gas leakage past the piston rings and into the crankcase. Prototype instrumentation was designed and developed to measure relative values of these parameters, and tests were conducted with several operating engines, some of them in Coast Guard cutters. Results of the development and test work were generally encouraging, but not definitive. This effort is therefore viewed as a step toward achieving the program goals. The report contains recommendations for further work. (Author)
