1 Emission reduction using Gecam fuel alone and in combination with different DPF 8 th ETH-Conference on Combustion Generated Particles Carlo A. Bertoglio Zurich, 16 th -18 th August 2004
2 AM TECNOLOGIE S.p.A. Cam Tecnologie, founded in 1997, is active in the field of emission reduction technology for diesel vehicles Cam Tecnologie is the market leader in the field of low emission fuels with Gecam TM, the white diesel, and is now also offering after-treatment devices for exhaust gases Cam Tecnologie is owned by Camfin Group, holding of the PIRELLI / TELECOM Group Employees Sales, 1,4 2,9 19,9 41,2 45,7 50,8 M

10 IGHT DUTY EMULSIFIED FUEL: TESTING ACTIVITIES During 2003 ENI and Cam Tecnologie have carried out an extensive testing program on a 6% water in diesel emulsion with the following targets: Verification of the ENVIRONMENTAL BENEFITS - against the project targets- of the new formulation on several different vehicles, and considering both REGULATED AND NON-REGULATED EMISSIONS Test program on bench and on track, under the supervision of FIAT-GM Powertrain, to verify the reliability of the product on vehicles equipped with the MOST RECENT HIGH PRESSURE INJECTION SYSTEMS ENI (Euron) test room, and a FIAT Stilo 1.9 JTD on the Nardò track
11 NVIRONMENTAL ASSESMENT PROGRAM: SOME FIGRUES Emissions result were verified on the amplest statistical sample : comparative tests between emulsified and standard diesel oil (3 runs) 5 independent laboratories were used to ensure consistency of results 23 different models tested, with various ages and mileages, to better sample the existing circulating fleet Tests repeated at different mileages (from 0 km up to 100,000 km) to verify result consistency over time Both homologation and urban cycles have been used Test rooms: ENI (Euron) and Stazione Sperimentale Combustibili
12 NVIRONMENTAL ASSESMENT: TEST FACILITIES Tests have been carried out at the following facilities: FIAT GM Powertrain, Torino Sangone Prototipo S.p.A., Proving Ground di Nardò (LE) ENI Tecnologie, San Donato Milanese Laboratory Stazione Sperimentale Combustibili, San Donato Milanese Engine Institute of the C.N.R.

19 ecam & AFTER TREATMENT: Filed test on CRT WHAT WE HAVE DONE: Performance test carried out in 2001 at TTM with good results We have switched our production with diesel base at 10 ppm sulphur 15 months field application with CRT Eminox on Euro 2 Busses in Milan, more than km each bus. RESULTS: Reduced engine soot load, opacity reduced by 70% before filter. Back pressure during running was 50% lower than with ULSD (10ppm S) No damage or extraordinary maintenance occurred. Positive impact on system maintenance and durability.
20 EVELOPING PARTICULATE FILTER SYSTEMS DEVELOPMENT OF NEW SOLUTIONS BASED ON: Strong role of CAM TEC on the Italian bus and truck fleet market Know-how on engine emissions, fuels and additives Dealers and technical customer support coverage all over the Italian territory Knowledge of European and North American retrofit market Knowledge of the automotive market evolution
21 EVELOPING PARTICULATE FILTER SYSTEMS DESIGN, DEVELOPMENT AND PRODUCTION OF PARTICULATE FILTER SYSTEMS OUR CHOICE: Silicon Carbide Support (from Liqtech) Regenerating Strategy with Fuel Borne Catalyst (for retrofit application) Self-developed Additive, Fe-based On-site Customer Support and life-cycle service warranty No sulphur constrain strategy emulsified fuel suggest.
22 IQTECH SiC FILTER CHARACTERISTICS 90 Cpsi - HI SOOT LOAD CAPACITY >18g/lt. - PORE SIZE 23 mm st at TTM in cordance with VERT: RTs Reduction 99,3% Tested at CERTH/CPERI on 1.9 lt CR Engine PARTs Reduction > 99 %
23 EVELOPING PARTICULATE FILTER SYSTEMS TEST ON FIELD - BUS APPLICATION: 7 lt. Iveco engine Euro 2 on Sub-urban application Constant monitoring dt,dp on road Regeneration from 270 C, pressure always below design limits km covered by every bus with no inconvenience FBC CAM additive compared on field with existing products. Emulsified fuel Gecam (350ppm S) compared with std diesel (350ppm)

25 ONCLUSIONS HOW TO CUT PM AND PARTICLES FOR EXISTING VEICHLES: Using emulsified fuels alone the reduction is about 50%. DPF give comparable emissions to CNG Vehicles, new support materials and FBC additive give enough warranty with very low initial cost. Service, cleaning and maintenance may be sold to users No Sulphur constrain would help the large diffusion before 2008 EU Legislation on Nanoparticles may lead National and Regional Authorities to promote Retrofit programs for clean fuel and Filters.
