Critical long-term stability of commercially available diesel with bio component
Engine manufacturers generally require diesel fuel in accordance with DIN EN 590, which today is blended with up to 7% biodiesel to comply with the Biofuel Quota Act. This diesel is designed for the transport sector with a consumption within 90 days, but not for long-term storage. In the case of biogenic admixtures, the risk of fuel-induced malfunctions of the emergency power system due to degradation and microbiological contamination of the fuel increases for fuel stocks during longer storage periods.
Installations with copper pipes accelerate fuel aging
Copper pipes are often used to supply fuel between the tank and the engine. However, the catalytic influence of non-ferrous metals leads to a faster ageing of the fuel with negative consequences for its suitability for use.
