Abstract
The formation of fuel deposits investigation is important to solve problems that involve with deposits in an engine. The problems become significant when bio-diesel fuel is used due to its higher density and T90 values compare to the typical diesel fuel. Fuel spray deposition test ' as conducted for diesel fuel (OF). palm oil based methyl ester bio-diesel fuels (B I 00) and bio-blended diesel fuel (85, 8 I 0. 820) by using Manual Fuel pray Apparatus (MFSA). DF. 85. B I 0, 820 and 8 I 00 sprays were impinged on a hot surface which has a surface temperature of 357°C at spray interval of I minute and 2 minutes. Every I0 spray repetitions, amount of deposit accumulated was measured. Maximum number of fuel spray for the deposition test was at I 00 fuel sprays. Comparison of deposit formation tendencies was made for all tested fuel s. Amount o f deposit accumulated for the fuel spray deposition were increased with the percentage of bio-diesel content in fuels. DF obtained lowest deposit development rate and lesser amount of deposit accumulated. However. 8 I 00 accumulated greatest amount of deposits compared to others. In term of deposit development rate, bio-diesel fuel and bio-blended diesel fuel have similar deposit development rate. It was found that, longer spray interval caused reduction of deposit development rate and amount of deposit accumulated at initial stage and final stage of deposition for diesel, bio-diesel and its blends. The fuel spray deposit formation in this study is depending on fuel spray interval, types of fuel. spray angle, deposit development rate. amount of deposit at initial stage of the deposition and the maximum evaporation rate point (MEP) of fuels.
