Özet

Diesel water emulsion is an alternative fuel for diesel engines which can be used in a main

engine of excursion boats and fishing vessels to reduce NOx emissions without any

additional engine adaptation in the existing engine installation. In this study,

implementation of emulsified fuel to diesel engine has been experimentally investigated

on the engine performance and NOx emission in a single cylinder, four stroke diesel

engine. The obtained results have been compared with standard diesel engine

performance and emissions. Emulsified diesel fuels of 5%, 10% and 15% water in diesel

fractions by mass have been studied at various engine speeds. The results show a NOx

significant decrease in NOx emissions with the increase in the amount of water in the fuel,

moreover the brake power decreases and the specific fuel consumption increases.
