View on GRPE formal documents for R83 and R115 (highlight discussion at GFV-20 and anticipated at GRPE-64). With respect to informal documents on which the two formal ones are based, in line with comments received in GRPE-63rd and as agreed by the group in GFV-18th, only that concerning R 115 has been subject to a significant modification: new requirements for petrol use in the gas mode have been restricted to direct injection petrol engines.

GFV-21-02 aims at introducing a mass correction factor for CNG reference fuel G25 in both documents ECE/TRANS/WP.29/GRPE/2012/6 and /7. A minor correction for the formulae used in both documents and for both gaseous fuels is highlighted: the proposed requirements make reference to gas ratios in percentage while the formulae generate decimal numbers. Attendees agree to correct the formulae making them consistent with the related requirements. Mr. Piccolo commits to drafting a proposal to be circulated to the group for final approval before tomorrow.
