Solving the Filtration Challenges for Diesel Fuel 2004-01-1451

Since the middle of the 1990s, Diesel motorizations have undergone a real revolution with the arrival of electronically-controlled high pressure injection system such as the Common-Rail or pump injector systems. The advantages of these systems are now well known: reduced consumption, reduced polluting emissions, reduced noise, etc. The diesel fuel filter, whose mission is to protect the injection system, must adapt to the changes in this system.
Among the features of these new systems, some have a direct impact on the definition of the diesel fuel filter. This more particularly concerns the reduction of operating clearance, which translates into great intolerance for water and solid particles found in diesel fuel.
The “diesel fuel filtration” function has seen its definition modified quite extensively. The required level of filtration performance and water separation has increased; new requirements, like initial cleanness, have been specified.
Alongside these new operational demands, diesel fuel filtration solutions must also satisfy other requirements like lengthening the intervals between maintenance services and the appearance of new fuels.
Offering manufacturers the best responses to all these requirements is the challenge for diesel fuel filtration systems.
