Abstract
The production of fossil fuel reaches its peak during the current decade. Unfortunately, the reserves of this fuel are depleting with time and limited to certain regions of the world which alarm for a series energy crisis in the future. Furthermore, the world starts to face the problem of global warming which increases rapidly and needs to be controlled.Waste cooking oil is one of the domestic available sources is the waste cooking oil. This source can represent a viable source in different countries which is free of cost. In this study, investigation of using a high blend of waste cooking oil biodiesel-diesel fuel is conducted in term of fuel property and engine performance. The results revealthat diesel fuel has the lower viscosity which is lower than that of WCOB by about 34%. However, this difference is converged with blended fuel B30 to about 9%. Furthermore, diesel fuel has higher heating value than WCOB by about 18%. However, this difference is converged with blended fuel B30 to about 4%.The maximum engine brake thermal efficiency observed with blended fuel B30 over the whole engine speed compared to mineral diesel and pure biodiesel. Accordingly, it can be suggested as a high blended fuel for diesel engine.
