This paper describes the effects of water-emulsified fuel on diesel spray combustion. Theoretical analysis and numerical simulation show that the high momentum of water-emulsified fuel spray per unit mass due to lower calorific value leads to higher air entrainment into spray than in the case of ordinary fuel. The experimental results show that these effects cause a reduction in the temperature of the combustion reacting zone of water-emulsified fuel spray, and a shortened combustion duration, and less formation of soot and nitric oxide in a diesel engine.
