What is PD CEN/TR 17548 about?
PD CEN/TR 17548 describes the investigation into diesel vehicle common rail fuel injection system damage and excessive wear problems in a number of countries across Europe since 2014 carried out by CEN/TC 19/WG 24 Abrasive Particles Task Force.
Investigation clearly shows internal damage to fuel injector moving parts, internal valves and pressure relief valves causing internal injector leakage, engine malfunction indicator light illumination, engine power loss, poor idle stability and in some cases complete engine shutdown.
Who is PD CEN/TR 17548 for?
PD CEN/TR 17548 on diesel fuel market issues is relevant to:
- Diesel fuel quality council
- Transportation stakeholders
- Fuel cell engineers
- Suppliers and manufacturers of abrasive water jet machines
- Vehicle manufacturers
- Fuel injection equipment manufacturers
Why should you use PD CEN/TR 17548?
Particle counting is a well-established and controlled testing procedure used in the hydraulic and aviation fuel industries with standards in both calibration and sampling with much better precision in comparison with existing gravimetric filtration methods.
PD CEN/TR 17548 summarizes the analysis by the fuel injection system manufacturers in the investigation report. PD CEN/TR 17548 identifies particle erosion as the root cause of the fuel injection system damage. The particles are shown to be hard and < 4 μm in size. The fuel injection equipment manufacturers have confirmed that the large number of particles found in the fuel and the fuel filters have not come from internal wear in the fuel injection equipment but from an external source.
PD CEN/TR 17548 assists the user with the particulate counting measurements made by a number of companies using a range of particle counting test methods. PD CEN/TR 17548 use the same basic particle counting method.
Overall, PD CEN/TR 17548 is helpful as it provides information on the conversion of particles per ml to ISO code numbers. PD CEN/TR 17548 contains advisory text on dirt and particle cleanliness.
