3. Investigation of the Effect of Canola Methyl Ester on Cyclic Variation Using Wavelet Analysis Method

Diesel engines are the most commonly used internal combustion engine in transportation, power generation, and other industries. Combustion in the diesel engines takes place at high temperatures due to the high compression ratio, and therefore high energy is obtained when diesel fuel is used. But the most commonly used alternative fuel diesel engines is biodiesel today. The market share of biodiesel is on the rise because of the increasing damage of diesel and decreasing oil reserves to the environment. In this study, cyclic variation that occurred when canola biodiesel (canola methyl ester) that is produced by transesterification method was used as diesel fuel was investigated. Three different biodiesel ratios, B20, B50, and B100 were used in the study. In interpretation cyclic variations wavelet analysis method is used and all results are compared with diesel fuel. It is concluded that the use of biodiesel in diesel engines has positive effect on cyclic variation and this effect increases with the increasing ratio of biodiesel in the mixture.
