Effect of Dimethoxy-methane ( C 3 H 8 O 2 ) on Combustion Characteristics of a Direct Injection Diesel Engine with Variable Compression Ratio , Fuelled with Biodiesel Blends with Diesel ( C

It is necessary to find a fuel source due to the heavy usage of natural resources. Developing countries have been trying various sources and methods to identify suitable alternative fuel for engines. This paper presents the utilization of Palm Oil Methyl Ester (POME) blends with diesel in Variable Compression Ratio (VCR) diesel engine. The performance and emission characteristics of biodiesel with 10% dimethoxy methane additive (20% Palm Oil Methyl Ester biodiesel with 10% DMM) for various compression ratios (15.5,16.5 and 17.5) have been studied and it was found out that the blends could substitute for diesel and used as an alternate source for the future generation. Emission parameter like CO, HC, NOx and Soot was evaluated and conclusions were drawn.
