GFV \| Session 23 \| 13 Dec 2012		As regards the company and its products: • Designer and manufacturer of AFV systems: mixers; gas injection & diesel blend systems for LPG and CNG • Customers include OEMs, importers & distributors in 50 countries • Designer and manufacturer of AFV systems: mixers; gas injection & diesel blend systems LPG & CNG; LNG systems being developed. • Replacement rates for dual-fuel systems: LPG 25-35%; CNG 35-50% • Customers include OEMs, importers & distributors in 50 countries • Has systems using air intake manifold and using multi-point fuel injection • Without after-treatment THC is higher but other emissions are reduced. B. As regards the company position in relation to the future UN regulatory framework: • A UN regulation is needed: In the absence of a UN Regulation, market entry without national regulatory procedures (homologation, safety checks, etc.) is not possible. • Regulation 115 could be the approach; • Emission limits: need some HC dispensation otherwise the addition of an appropriate after-treatment device makes the entire system too expensive; • Test protocol: o Should avoid expensive testing equipment; o The right family definition should generate an affordable number of emission tests.
