The fuel filters are an important component in the fuel system. The filter separatesharmful contamination from the fuel to protect the other components.To be able to test fuel filters in a simulated environment Scania wants to develop anew fuel filter test bed. The demand is to test at least two filter pairs that experiencethe same pressure and flow as they do in a vehicle. To be able to use the rig for manyyears it has to be adaptable for the next generations of filters and filter houses. Thereis also a demand that the rig is mobile and can be run at different locations, attachedto different types of fuel tanks.The projected resulted in a final concept of the fuel filter test bed and a prototype.The prototype of the rig is not a copy of the concept, but a smaller version of theconcept to test some of its functions. The prototype rig worked as hoped for.
