AB - As an attempt to suggest an alternate fuel for diesel with less emission, the  effects of Diesel-hexanol blends, blended in different percentage ranging  from 10%-50% by volume were experimentally investigated on a singlecylinder,  water-cooled, direct injection diesel engine developing a power output of  5.2 kW at 1500 rev/min and the results show improved performance with blends  compared to neat fuel with substantial reductions in smoke and increase of  NOx emissions. Combustion analysis show peak pressure and rate of pressure  rise were increased with increase in hexanol. For this reason it is examined  the use of hot exhaust gas recirculation (EGR) to control NOx emissions.  From the analysis of experimental findings it is revealed the use of EGR  causes a sharp reduction of NOx with a slight reduction of engine efficiency  which in any case does not alter the benefits obtained from the oxygenated  fuel.
