Lite White Diesel based on Specialdestillat Marine on a marine diesel engine

On comission by Eco Energy Holding AS, MARINTEK (The Norwegian Marine Technology Research Institute) conducted tests with Lite White Diesel based on Specialdestillat Marine. The emulsified fuel is prepared by adding water together with an emulsifying agent and then mixed well. Additives to improve ignition might also be added as an option.

The purpose of the test was to verify the effect of different water content with respect to exhaust emissions and fuel consumption. The tests comprice one reference fuel and four emulsified fuel qualities based on the reference fuel with water added: 11.5, 13, 14 % water.

A summary of the results

  • The average NOx reduction factor is measured and calculated to be 0.57. This means that The NOx emission is reduced by 0.57 % for each percent of water that was added to the fuel (within the tested range (11.5 to 14 % water).
  • The average CO reduction is found to be 35 %.
  • The change in THC emission range from -5.6% to +33% with the higest water content.
  • The smoke emission is significantly reduced with emulsified fuel. The average smoke reduction is found to be about 50 %.
  • Particulate emission is, on average, reduced by about 29 %.
