Abstract

The ERC company has had an additive tested for its effect on the combustion behaviour and soot (exhaust gas) emission of marine fuels under shipboard conditions in a slow-rotating, 2-stroke crosshead diesel engine 6RTA72. Analysis of the determined combustion processes showed that when additve was used the combustion was completed sooner and the combustion turnover reduced whilst process and exhaust-gas temperatures were lowered at the same time. Moreover, reduced soot (exhaust gas) emission was recorded. Preliminary remarks Due to the steadily decreasing quality of the fuels supplied to shipping on the international bunker markets, problems of combustion arise in diesel engines. As a result the problems of incomplete combustion and the occurrence of heavy soot formation and high emission of other exhaust gas constituents ar
