Use of hazelnut oil ethyl ester as a fuel in pre-chamber diesel engine

This study briefly reviews the use of hazelnut oil ethyl ester which was produced by hazelnut oil as an alternative fuel in pre-chamber diesel engines, and compares it with pure hazelnut oil and diesel fuel. In the experiments, a naturally aspirated, pre-chamber indirect injection, four cylinders, four-stroke diesel engine was used. During the test, power, torque, emissions values, and fuel consumption were measured with respect to the engine speed. As a viscosity and density of hazelnut oil ethyl ester was found to closely similar to those of diesel fuels. Test results obtained from hazelnut oil ethyl ester were compared to hazelnut oil and standard diesel fuel test results. CO, NOx, smoke density of hazelnut fuel, and exhaust temperatures were lower than of diesel fuel. The biodiesel NOx emissions higher than diesel fuel all engine rpm and NOx emission was measured 15 % higher from the diesel fuel. The specific fuel consumption is increased: At low-speed 6 %, medium speed 9 %, and high-speed 12 %. The average increase in specific fuel consumption 9.7%is determined. As a result of this study, it is concluded that hazelnut oil biodiesel could be used as an alternative fuel in diesel engines. © Springer International Publishing Switzerland 2014.
