Application of Jatropha Gossypiifolia Linneus Seed Oil as Additive for the Reduction Fuel Consumption from Diesel Engine Combustion

Jatropha Gossifiipolia linnues is also grown in different parts of Nigeria especially the northern parts. It is usually planted to grow as live fences and hedge plants in homesteads and gardens. Its ecological performance in the country is such that it can grow in the semi arid, arid and tropical climate. The is a robust woody shrub of light gray bark which may reach an average height of 4m in not so favourable environment and a good average of 9 m in good climatic conditions. The burning of fossil diesel fuel is one of the biggest contributors of pollution in the environment. Diverse factors such as global environmental issues, increasing petroleum prices, and the fact that the fossil diesel fuel is finite are some of the reasons why researchers are seeking to cleanly burn diesel engines with other fuels. Biodiesel can also be used as fuel and it can even be blended with diesel in their various proportions. This research is pure quantitative experimental research to determine the effect of the additive on diesel engine fuel consumption. Using Perkins 2200 SERIES 2206A E13TAG2 diesel engine. It is a 13L, 6 cylinder, turbocharged, aftercooled engine with a direct injection electronic control system, and prime power of 350kVA 280kW . The Jatropha seeds were pressed using screw press at 120 rpm. The oil that was extracted was subjected to a thermal chamber at 1200C to eliminate the content of moisture. Crude Jatropha oil was combined with the conventional diesel in 5 , 10 , 15 , 20 and 25 . Each of the samples was heated with three temperatures 40, 60 and 800C and was identified as JD1, JD2, JD3, JD4, JD5, Crude Jatropha oil CJ and diesel fuel. Results show that two major trends. Firstly, the viscosity of the diesel blends is rising with the concentration of JSO in the diesel. Diesel fuel record viscosity of 3.06mm2 s at 400C. The viscosity of JD1 5 JSO is 5.55 mm2 s which gradually increases to 7.67 mm2 s JD2 , 18.4 mm2 s JD4 , and 24.98 mm2 s JD5 . Crude Jatropha oil CJ has the highest viscosity of 31.15mm2 s at 400C. This pattern is found in all the experimental temperatures 600C and 800C . The 5 JSO mixture DJ1 and the 10 JSO mixture DJ2 consume less fuel as compared to standard diesel at all engine loads. DJ1 draws 68.0 L hr and DJ2 draws 71.0 L hr at 100 load which are much lower than the 80 L hr of diesel. At a load of 25 , DJ1 16.4 L hr is significantly lower than diesel 23 L hr . There is increase in fuel consumption as the ratio percentage of JSO being used in the blend increases between DJ1 and DJ5. To illustrate, FC represents 55.0 L hr in the case of DJ1, 58.5 L hr in the case of DJ2, 62.5 L hr in the case of DJ3, 67.0 L hr in the case of DJ4 and 72.0 L hr in the case of DJ5 75 load . Nasir A.
