The lubricating oil and boiler feed water contamination is a regular feature in maritime operations. The author of this paper has stumbled upon the practical maritime problem of contamination of diesel fuel used for ship propulsion engine with the seawater. In the event of this contamination of diesel oil the author has made up his mind to evaluate the performance of a laboratory based diesel engine with various possible percentages of diesel emulsions with seawater closely keeping track of the engine performance. The experimentation is conducted on a laboratory based DI 4-stroke Diesel engine (5 hp at 1500 rated RPM with Compression ratio 16.5) varying percentages of Diesel seawater emulsions. Appropriate engine data recorder and software is used to register the pressure variations with respect to crank-angle and heat release rate for various combinations of seawater and diesel emulsions.
