The paper deals with water/diesel emulsion effects on injection and combustion characteristics of a bus diesel engine. The influences of water content in water/diesel emulsion are investigated by numerical simulation. Higher content of water in water/diesel emulsion increases the injection pressure and decreases the in-cylinder gas pressure, in-cylinder gas temperature, and rate of heat release; this leads to lower engine torque and power. The obtained results indicate a possibility of essential reduction of NOx and soot emissions by increasing water content.
