Heavy duty transportation is a growing area where the reduction of fossil fuels would be highly beneficial for the environment. A feasible way in the truck industry to achieve lower greenhouse gas emissions is the use of renewable fuels. Since the most common propulsion system in heavy duty vehicles are diesel engines, suitable renewable fuels include biodiesel, also known as fatty acid methyl ester (FAME). Although there are regulations for biodiesel such as ASTM D6751 and EN 14214, due to known drawbacks such as its susceptibility to degradation or its bad cold flow properties, using biodiesel in trucks could still cause unwanted effects to the filter system. Furthermore, these standards are not applicable in every part of the world. Thus investigation of the contaminants which could create soft deposits and plug filters is required. From previous experiments it is known that soft deposits mainly consist of fuel degradation products such as metal carboxylates, or impurities from the biodiesel production. The aim of the work is to present a filter system where the interaction of deposits with the filter materials and with each other can be studied...
