Characterization of Deposits Collected From a Plugged Fuel Filter
Fuel filters serves as a safety belt for modern compression ignition engines. To meet the requirements from environmental regulations these engines use the common rail injection system, which is highly susceptible for contamination. Further the public awareness towards global warming is raising the need for renewable fuels, such as biodiesel. The higher fuel variety brings a higher requirement for fuel filters as well. To better understand the process of filtration, awareness of the different possible contaminants from the field is needed. This study used several chemical characterization techniques to examine the deposits from plugged filters collected from the field. The vehicle was run with biodiesel blends available on the market.
