Annual Conference of the Misr Society of Agricultural Engineering "Agricultural Engineering and Country Challenges"; Includes references N2 - Biodiesel has become one of the most important sources of renewable energy which can be used with diesel engines. In order to decrease production cost, waste frying oil was used as a raw material instead of fresh vegetable oils to produce low cost biodiesel. A Kubota M-90 tractor of 66.2 kW was tested with 300 kW hydraulic brake stationmy dynamometer.. The performance of diesel engine using mineral diesel was higher than biodiesel at all engine efficiencies of PTO torque. PTO power.
