Comparative engine characteristics of biodiesels from hazelnut, corn, soybean, canola and sunflower oils on DI diesel engine

In this study, engine performances of five different kinds of biodiesels produced from five different vegetable oils (corn, sunflower, soybean, canola and hazelnut) were compared with each other and with diesel fuel in the same experimental system. Therefore, biodiesel samples that include different ratios of (20%, 50%, and 100%) biodiesel in diesel fuel for each biodiesel sample was prepared after biodiesels were produced by transesterification method. Every sample was used as fuel in the diesel engine. Both effective characteristics and indicated characteristics were determined for each fuel during engine test. All values were compared each other graphically. Finally, it was found that the mixture consists of 20% hazelnut biodiesel has the best performance.
