Abstract :Fuel properties of Sandbox Methyl Ester insert ignore into journalissuearticles values(SBME); blends were experimentally determined. Pure SBME designated B100 was blended with diesel at 5, 10, 15, 20, 25 and 50% volume designated B5, B10, B15, B20, B25 and B50 respectively. The fuel properties were determined according to American Society for Testing and Materials insert ignore into journalissuearticles values(ASTM); standards. Automotive Gas Oil insert ignore into journalissuearticles values(AGO); was used as a reference fuel. Fuel properties of the SBME were modified with the addition of diesel percentage in the blend from B100-B5: the density ranged from 891-865 kg m-3. The specific gravity ranged from 0.87-0.82. The kinematic viscosity ranged from 5.8-4.0 mm2 s-1. The flash and fire point decreased from 160-90°C and 230-140°C, while the cloud and pour points ranged from 4.6-3.4°C and -5.8-insert ignore into journalissuearticles values(-9.2);°C respectively. The heating value ranged from 40.50-41.45 MJ kg-1. The Cetane number for the SBME was 46.71. The saponification value ranged from 200-143 mgKOH g-1. The acid value varied from 2.7-2.2 mgKOH g-1, while the FFA content varied from 1.33-1.10 mg g-1. The Iodine value was in the range of 108-94 gI2 100g-1. The pH value varied from 6.80-5.60. The carbon content increased from 80.02-85.62 wt%, while the ash content increased from 0.01-0.16 g 100g-1. In comparison to the insert ignore into journalissuearticles values(AGO); and the ASTM standards, SBME was found to possessed good flow, ignition and combustion characteristics to power diesel engines.
