Abstract
Water fuel emulsion is widely used to control pollutant emissions in large and medium diesel engines. The application of this fuel to small automotive engines has been limited by the emulsion stability and economic difficulties to calibrate engine parameters for a new fuel. This work is focused on the effects of the use of water fuel emulsion on standard automotive engines performances and on pollutant emissions. No specific calibration or modification of engine has been carried. The effective benefits of water fuel emulsion combustion are explained. Particularly, emitted particulates are reduced by half, EPA referenced PAH concentration in the particulate are reduced by a factor of three, and NOx by 40 %, compared to the same engine operating on standard commercial fuel. Both standard and common rail direct injection systems were tested and a special study was dedicated to cold start pollutants showing the large production of carcinogenic compounds.
