3 Agenda System description Emission data for fluorinated HD-PE systems Emission data for coextruded HD-PE systems Emission results for US-systems (for reference) Conclusions

4 System Bounderies Filler cap excliuded from measuremants * Individual deviation from this borders are highlighted in each diagram

5 Fluorinated Tank systems Fluorinated-Tanks are produced with a HD-PE Monolayer Structure. The inner surface treated with Fluorine Gas (F 2 ) during or after the blow moulding process to reduce HC-Emissions

6 Typical Soak Duration Example: One-Chamber Tank Fuel Tank Supplier Kautex Textron Production Technology HDPE Fluorinated CEC-RF (E0) 45 l Storage duration 24 weeks Typical Limit for Fuel System

7 Emissions [mg/day] Typical Soak Duration Example: Durability Fuel System (incl. Filler Pipe) Fuel Tank Supplier Inergy Production Technology HDPE Fluorinated Carb Phase III (E10) 50 l Storage duration 30 weeks Typical Limit for Fuel System Vehicle Road Driving km / 24 months static soaking static re-soaking (average on 2 systems) after vehicle aging Soaking Duration [Weeks]

8 ~ 450 mg Emissions [mg/day] Typical Soak Duration Example: One-Chamber Tank Typical Limit for Fuel System Fuel Tank Supplier Kautex Textron Production Technology HDPE Fluorinated Storage Fuel E5 CEC-RF (E5) 45 l Storage Duration 24 weeks Additional Emission for Components 400 Tank Shell only Soaking Duration [Weeks]

9 Emissions [mg/day] Typical Soak Duration Example: One-Chamber Tank Fuel Tank Supplier TI-Automotive Production Technology HDPE Fluorinated CEC-RF (E5) 35 l Storage duration 19 weeks Typical Limit for Fuel System Soaking Duration [Weeks]

10 Emissions of CoEx Tank Systems CoEx-Tanks are produced with a 6-Layer Structure to reduce HC-Emissions Outside outside Inside inside adhesive Regrind layer Barrier layer 1. HD-PE 2. HD-PE Regrind 3. Adhesive Layer 4. EVOH Barrier Layer 5. Adhesive Layer 6. HD-PE

11 Typical Soak Duration Example: Saddle Tank Fuel Tank Supplier Kautex Textron Production Technology 6-Layer CoEx CEC-RF (E5) 55 l Storage duration 22 weeks Typical Limit for Fuel System

12 Emissions [mg/day] Typical Soak Duration Example: One-Chamber Tank Fuel Tank Supplier MM PCMA Production Technology 6-Layer CoEx Storage Fuel E10 CEC-RF (E0) 45 l Storage Duration 22 weeks 1000 Typical Limit for Fuel System Soaking Duration [Weeks]

13 Emissions [mg/day] Typical Soak Duration Example: Saddle Tank Fuel Tank Supplier TI-Automotive Production Technology 6-Layer CoEx Storage Fuel E5 CEC-RF (E5) 65 l Storage Duration 24 weeks Typical Limit for Fuel System Soaking Duration [Weeks]

14 Emissions of US-Systems For Reference : Legal Fuel System Limit: 350 mg (PZEV) 54 mg (rig test)

15 Emissions [mg/day] Typical Soak Duration Example: Durability Fuel System (excl. Filler Pipe) Fuel Tank Supplier Inergy Production Technology 6-Layer CoEx Storage Fuel E10 Carb Phase III (E10) 65 l Storage Duration 80 weeks Legal Limit for Fuel System (Rig Test) = 54 mg Soaking Duration [Weeks]

16 Emissions [mg/day] Typical Soak Duration Example: Durability Fuel System (excl. Filler Pipe) Fuel Tank Supplier Kautex Textron Production Technology 6-Layer CoEx Storage Fuel E10 Carb Phase III (E10) 57 l Storage Duration 37 weeks Legal Limit for Fuel System (Rig Test) = 54 mg Soaking Duration [Weeks]

17 Emissions [mg/day] Typical Soak Duration Example: Durability Fuel System (incl. Filler Pipe) Fuel Tank Supplier TI-Automotive Production Technology 6-Layer CoEx Storage Fuel E10 Carb Phase III (E10) 50 l Storage Duration 29 weeks Legal Limit for Fuel System (Rig Test) = 54 mg Soaking Duration [Weeks]

18 Conclusions Emission stabilization is achieved after 20 weeks soaking time at 40 C Current technologies can fulfill required emission levels Long term emissions can be derived and predicted based on 20 week SHED measurements on tank system level
