Experimental analysis of energy, performance and noise emissions for biodiesel fuel obtained from animal waste fat

Animal fats are one of the biodiesel raw materials. In this study, biodiesel was produced from horse fat by transesterification method and the produced biodiesel was mixed with euro diesel at 5% by volume, and experimental fuels in the form of D-100 and D95B5 were obtained. Fuel properties of test fuels were determined. In addition, using the experimental fuels in a single-cylinder, four-stroke, water-cooled diesel engine, the data obtained by investigating the engine performances, energy analysis, and noise emissions were presented with graphics and interpreted. In the experiment results; D95B5 fuel produced 0.68% more torque than D-100 fuel at maximum torque value and D95B5 fuel produced 4.06% more power than D-100 fuel at maximum engine power. In the minimum specific fuel consumption values, D-100 fuel consumed 4.70% less fuel than D95B5 fuel. In terms of energy analysis, results are given for the maximum torque speed 1200 rpm, minimum specific fuel consumption speed 1200 rpm, and maximum power speed 2000 rpm for the experimental fuels. In terms of noise emissions, the engine made 0.56% less noise in the use of D95B5 fuel compared to the use of D-100 fuel and 0.20% less noise at the maximum torque speed values, according to the average values of the maximum power cycle. As a result, adding 5% horse fat biodiesel to diesel fuel has yielded positive results in terms of engine performance, energy analysis and noise emission. This type of fuel can be used in diesel engines without any modification.
