Özet

The fuel additives have been studied by many researchers on diesel engine performance and encouraging results have been obtained. During the combustion fuel additives provide the catalyst effect, accelerates the reaction instability and create positive effects on engine performance. In this study; biodiesel was produced by transesterification from the refined cottonseed oil, a certain amount of n-heptane were added in biodiesel and combustion and performance tests were conducted. The experiments was made in a single-cylinder diesel engine at a constant speed and full load. n-heptane added into the cotton methyl ester (PH0) fuel improved the fuel atomization therefore combustion efficiency increased. The maximum power increase was 7.52% in cotton methyl ester fuel containing 8 % n-heptan (PH8). The maximum gas pressure and maximum heat release are formed in almost the same crank angle for all fuels. The 8% n-heptane mixture given the best results in terms of engine performance and combustion characteristics.
