| Initial efforts with water/fuel emulsions in diesel engines were directed toward the control of NOx. More recent studies emphasized the use of emulsions to improve fuel economy. It is believed that in a diesel engine combustion process, emulsified fuel droplets would undergo micro-explosions that would decrease the heterogeneity of the injector spray pattern and thus increase the efficiency and fuel economy. Although all data in the literature indicate that emulsions ... |
