PRODUCTION OF HAZELNUTOIL METHYLESTER, PERFORMANCE AND EMISSIONS ANALYSES AS A FUEL IN DIESEL ENGINE

In this study, briefly reviews as a fuel of hazelnutoil methylester use alternative fuel in pre-chamber diesel engines and compares to diesel fuel. For this purpose, a naturally aspirated, prechamber indirect injection, four cylinder diesel engine was used and without any modifications to the experimental engine. Hazelnutoil methylester test results were compared to test results of diesel fuel. Hazelnutoil methylester viscosity higher from diesel fuel, but hazelnutoil methylester density is lower from diesel fuels. Hazelnut oil methyl ester emissions compared to diesel fuel, CO, HC, and CO2 emissions lower, but NOx and smoke emissions higher were observed. As NOx emissions, hazelnutoil methylester higher than diesel fuel and NOx emission was measured approximately 12% higher from the diesel fuel all engine rpm. It was observed; the specific fuel consumption increased, at low-speed 5%, medium speed 7%, high-speed 10%. The average increase in specific fuel consumption 8% determined. Hazelnut oil methyl ester compared to diesel fuel, engine torque and engine power performance are decreased 10% was observed. As a result, hazelnut oil methyl ester could be used as an alternative fuel in diesel engines.
