Abstract
The marine industry is faced with new tough emission regulations. Experimental results are reported on gasoil and LCO (light cycle oil) water-in-fuel emulsions, on effects of nitrogen enriched charge air and on the combination of the two technologies. The Two Color Method is applied and results compared with the Back Diffused Laser method, while emissions and rates of heat release are discussed. The potential of using emulsions to improve the combustion process, drastically reduce soot and potentially to lower NO_x emissions is demonstrated, while the combination with nitrogen enriched charge air to drastically reduce NO_x emission leads to a promising solution by combining advantages.
