5. Overview of the drafting work since GFV-43 (Mr. Dekker) (PowerPoint presentation GFV-45-04). This presentation is an adaptation of the one made in GFV-43 (GFV-43-06). The two presentations provide an overview of the new regulation for retrofit systems intended to be fitted on a heavy duty diesel vehicle to enable its operation either in diesel mode or in dual-fuel mode. The regulation includes Euro V and EEV engines.

At GFV-43 concerns were raised by Germany about chassis dynamometer test procedures and by the legal staff of DG-Growth (European Commission) about approval of ‘non-compliant diesel engines’. DG Growth was concerned about language specifying the possibility to perform retrofit system type approval on a non-compliant demonstration engine (even when the retrofitted engine would be compliant on DF operation). Germany requested that the simplified engine test bench (ESC only) and chassis dyno tests and provisions for increased CO emissions be removed.
