Influence of Fuel Properties on the Combustion in Diesel Engine Driven by the Emulsified Fuels

Abstract

The authors investigated the influence of fuel properties on combustion with various emulsified fuels in a direct injection diesel engine. Results show that water-to-C heavy oil emulsion reduces NO_x, CO and smoke as water-to-gas oil and water-to-C heavy oil emulsions do. The improvement of the specific fuel consumption, however, is less remarkable than expected. This is because the effect of water vapour explosion is smaller than in the other emulsified fuels.
