Objectives of the study
The objectives are:
- to follow performance of 5 Peugeot 607 taxis running in Paris traffic over 80,000 km
- under severe conditions (low speed, long idle period, urban traffic jam, low exhaust temperature…)
- on the exhaust emissions
- in term of efficiency and durability of the PSA’s DPF System

Evaluation programmes
- Five vehicles using a standard European Diesel fuel (350ppm sulfur)
- Characterizations and evaluation every 20,000 km over 80,000 km (EURO 3 standard requirement in durability)
- Regulated pollutants (CO, HC, NOx, particulates) over the MVEG Cycle
- Fuel consumption (MVEG and Field Operation)
- Non-Regulated Emissions
- Durability and reliability of the DPF System

Good agreementin Ceria balance,
and consistent withthe VERT Certification
Very Low level of Particle emissions after the DPF:- Sulfur: 2 to 7 ng depending on the vehicle- Potassium or Calcium: 0,2 ng- Iron and Nickel: traces- Ceria: undetectable (even using PIXE analysis)

Conclusions
The « FAP » technology limits the particulate matter emissions under 5 mg/km over the MVEG cycle (far below the EURO 4 PM standards)
Even during DPF regenerations, the particulate emissions remain below the EURO 4 limitation
Non-regulated emissions are reduced by the DPF System under significant proportion
No Cerium leakage through the SiC-DPF
The efficiency, durability and reliability were demonstrated over 80000 km, even under severe driving cycle conditions (low speed,long idle)
Next step : durability at 120,000 km trap after re-manufacturing
