Numerical Analysis of Diesel/Water Emulsion Fuel in a Diesel Engine

In order to reduce the emission of carbon dioxide and dramatically reduce smoke and NOx in the exhaust emissions, there have been many recent attempts to use diesel/water emulsified fuel in diesel engines. Some studies reported that as the proportion of water increased, smoke and NOx could be reduced by as much as 50% under full load conditions. However, there was virtually no change in the fuel consumption rate. To ensure smooth engine operation, water can be added to diesel fuel in amounts of as much as 30%. And as more water is added, the ignition delay time becomes longer due to the evaporation of water, which causes a change in the ignition-combustion process. The purpose of this study is to review these effects.
