Abstract

The invention relates to a method and a device for operating a diesel motor using a fuel that comprises vegetable oils or recycled vegetable oils. The fuel is withdrawn from a tank, filtered through a fuel filter and injected into the cylinders through injection nozzles by means of an injection pump. Any excess fuel is returned. The fuel is transferred from the tank via pressure-resistant fiber filters by means of a forcing pump to a storage reservoir, where it is irradiated ultrasonically. The fuel is sucked out of the storage reservoir by the injection pump and excess fuel is returned to the storage reservoir.
