are recommended. The engine should be started and before stopping run by
using diesel alone. After warming up it should be shifted to the vegetable oil
blend. These problems can be sorted out by routine and preventive maintenance of engine. Heating of vegetable oils could reduce their viscosity and
hence improve the spray pattern of vegetable oil atomization that leads to
improvement in engine performance. As the engine requires frequent maintenance, this is best suited for stationary engine application particularly
