This informational workshop is organized under the chairmanship of GFV to discuss and help determine what regulatory pathway should be taken in regards to the type-approval of Heavy Duty Dual-Fuel (HDDF) retrofit systems. The discussion follows is a result of the work being done by the Heavy Duty Dual-Fuel Task Force (HDDF TF) on new dual-fuel vehicles/engines.

The results of the workshop will provide input to the HDDF TF in order to produce possible UN provisions for the type-approval of HDDF retrofit systems.
