PROBLEMS ASSOCIATED WITH DIESEL ENGINES OPERATING ON FUEL OF POOR QUALITY

There is a continuous struggle to find methods to obtain economical operation of ships. The prospect of global energy shortage has its impact on the price and quality of fuels offered to the marine market. With freight as low as they are today and profits and expenses often near the break even point, fuel economy is a major concern. The cheapest fuel is, in general terms, the one which offers the greatest threat to engine reliability. The quality of heavy fuel oil, however, varies widely depending on which refinery process and type of crude oil it is derived from. The specifications according to which it is ordered are rather few and are almost completely irrelevant for the quality of the product. Our knowledge as to which are the relevant criteria to use when evaluating the combustion quality of a fuel is limited. Therefore, research work has been, and is being carried out by Det norske Veritas in cooperation with others. The aim of this work is to determine which fuel properties are important, how these properties may be measured, how incipient trouble caused by poor combustion may be detected, and how the harmful effects may be counteracted.
