Proposal from CLEPA to introduce type-approval requirements for Liquefied Petroleum Gas (LPG) fuel selection systems, including with regard to engine control units (ECU), CNG start-stop functionality, and a prohibition against the flow of gaseous fuel into the petrol/diesel fuel tank and vice versa.
33. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSG/2013/10 proposing to introduce into UN Regulation No. 67 type approval provisions for electronic control units (ECUs). GRSG adopted the document, not amended, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2013 sessions as part (see para. 32 above) of draft Supplement 13 to the 01 series of amendments to UN Regulation No. 67.
34. The expert from CLEPA presented ECE/TRANS/WP.29/GRSG/2013/11, ECE/TRANS/WP.29/GRSG/2013/12 and GRSG-104-18 proposing to introduce into UN Regulation No. 67 type approval provisions for fuel selection systems respectively for “valve control at the stop-start function”. Recalling the discussion on the same subject under agenda item 8 on UN Regulation No. 110 (see paras. 38 and 39 below), GRSG agreed to resume consideration on this matter at its next session. In this respect, the Chair invited the expert from CLEPA to prepare, if necessary, updated proposals.
37. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSG/2013/10 proposing to introduce into UN Regulation No. 110 type approval provisions for electronic control units (ECUs). GRSG adopted the document, as amended, and agreed to reflect the adopted text in GRSG-104-44, mentioned above.
38. The expert from CLEPA presented ECE/TRANS/WP.29/GRSG/2013/11 proposing to introduce into UN Regulation No. 110 type approval provisions for fuel selection systems. GRSG noted a number of concerns and preferred to refer the proposal to the informal group on Gaseous Fuelled Vehicles (GFV) for detailed consideration at the forthcoming session in Brussels. GRSG agreed to resume consideration on this subject at its next session on the basis of a revised document by CLEPA.
39. The expert from CLEPA also proposed to introduce type approval provisions for “valve control at the stop-start function” into UN Regulation No. 110 (ECE/TRANS/WP.29/GRSG/2013/12). The expert from OICA presented GRSG-104-19 improving the proposed text. GRSG agreed in principle on the both proposals, but preferred again to refer the proposal to GFV for detailed review. GRSG agreed to resume consideration on this subject at its next session on the basis of a revised document by CLEPA.
