The invention relates to a method for producing a fuel from vegetable oil in order to operate of diesel internal combustion engines. In said method, the oleaginous fruit is pressed, and the dripping oil is filtered. According to the invention, the dripping vegetable oil containing the cloudy matter is mixed with a clay material in a first step before being filtered and is filtered in a second step.

Method for the production of a fuel from vegetable oil

A diesel cycle internal combustion engine can be operated with a variety of fuels having different boiling points and different viscosity-temperature characteristic curves, with a fuel circuit that includes a fuel tank, a fuel pump, a fuel line, at least one fuel filter, a high-pressure pump, an injection system device and a return line to return fuel to the fuel tank, where a control valve is provided in the return line for dividing or diverting the fuel flow to the fuel tank and/or to the fuel filter, and where the fuel division or diversion is undertaken as a function of the viscosity of the fuel in use such that the fuel filter will thence be heated to a temperature based on heat transfer from the fuel in use, and further where a pressure relief valve is provided between the fuel filter and the high-pressure pump.
