For a high speed Diesel engine , gas oil and lighter heavy oil are used in general, but, in order to reduce NOx (Nitorogine Oxide) in exhaust gas and also to prepare for the future world wide oil shortages, blends of alternative fuels, such as alcohols are of interest. These additive to Diesel engines have been studied for a long time in this institute, as well as in many other institutes in JAPAN.
Here, the ignition temperature of blended gas oil and others, mixed with various alcohols (mainly ethanol) and Decanol or Isoamyl Ether, are measured independently to analyse the effect of this blending on the improvement of emission quality. Ethanol is of paticular interest because it is a fuel produced from all biomass including cereals, rice, corn, potatoes etc, crops widely produced in many places in the world, as seen in Figure 1.
In this paper, the measured ignition temperatures of alcohol blended fuels, including Decanol or Isoamyl Ether are reported, showing the strong solution effect of Decanol or Isoamyl Ether for blending, thus allowing for wide engine conditions.
Further, also reported are the engine performance and exhaust gas emission results using these blended fuels.
