Abstract:

The work reported here is the final effort in a study to determine the feasibility of burning waste crankcase lubricating oils in Coast Guard powerplants. Specifically, the program reported here was to determine if burning a mixture of used lube oil and diesel fuel in a two-stroke cycle diesel engine resulted in increased rates of ring wear relative to that observed with standard fuel. Piston ring wear rates were measured by the radioactive tracer technique. Four top compression rings of a Detroit Diesel 6-71 engine were made radioactive, and the wear particles present in the crankcase oil from these rings were measured by gamma ray spectrometry. In 210 hours of operation, using diesel fuel with used lube oil up to 10 by volume, no increased wear rates were measured. The engine was disassembled upon test completion, and the wear and deposit build-up on critical engine components were nominal for this type of engine and total operating hours. Author
