The Emission Characteristics of the Emulsified Fuel and its Mechanism Research of Reducing Diesel Engine NO_x Formation

Abstract:

A non-turbocharged, direct-injection single-cylinder 1135 diesel engine was measured to investigate the engine fuel economy and emission characteristics with emulsified fuel that contains 18% water by volume. At the same time, the mechanism of reducing diesel engine NOX formation was discussed. The results showed that the diesel engine fueled with emulsified fuel leads to significant decrease in the emissions of soot and NO_x and proper increase in fuel-efficiency without modifications in engine structures comparing with the diesel fuel. This paper analyzed that the water physical chemical role has an effect on reducing emulsified fuel thermal NO and prompt NO formation.
