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.
