The liquid phases in four-component microemulsions are discussed emphasizing the identity association between colloidal solutions and microemulsions. By careful choice of emulsifiers it is possible to provide microemulsions based on diesel oil which exhibit an ignition performance suitable for high speed diesel engines. These microemulsions show a pronounced net benefit in the NO and smoke emissions. The amounts of unburned hydrocarbon and CO in the exhausts do increase but may be reduced by a catalytic afterburner. The emission changes obtained with the microemulsion fuels parallel, to a considerable extent, those reported for gasoline-methanol fuels. For these fuels measurements of emitted amounts of polynuclear-aromatics (PNA) have also been performed and showed that simultaneously with the decrease in soot and NO a decrease in PNA was obtained. It is therefore most plausible that a similar decrease will be observed for the microemulsion fuel. The need for emulsifiers in the microemulsion fuels and the fact that a slight increase in fuel consumption was registered will lead to higher costs for the use of microemulsions as diesel fuels. The utilization is limited to places where the cleaner exhausts regarding soot and NO and most probably PNA will bring considerable savings. Such a case is in mining, where most of the working engines are diesels and in general already equipped with a catalytic afterburner for CO and HC.
