ABSTRACT

Water/diesel (W/D) emulsified formulations are reported to reduce the emissions of Nitrogen dioxide, Carbon monoxide , Carbon dioxide and particulate matter (PM) without compensating the engine’s performance and to increase Specific fuel consumption .

Emulsification process

(Diesel + Water + Surfactant)

(Emulsion)

EMULSIONS

In spontaneous emulsions, the mixing is easy .But if they

don’t mix properly then a third chemical called a surfactant

is used to bind the molecules of the constituent liquids.

DIESEL WATER EMULSIONS

Diesel water emulsions have come into recent

field of study. When mixed directly, diesel

being a lighter liquid than water diesel comes

to the top and water settles in the bottom. By

using an appropriate surfactant the molecules

of water and diesel can be bound together

SURFACTANTS Surfactants are compounds that lower the surface

tension of a liquid that is it decreases the interfacial

tension between two liquids, or that between a liquid

and a solid. Surfactants may act as detergents, wetting

agents, emulsifiers, foaming agents and dispersants.
