This informal document aims at correcting and clarifying the draft amendments to Regulation No. 110 as proposed in WP.29/2013/101. At its November 2013 session, the World Forum WP.29 is expected to consider and adopt draft Supplement 1 to the 01 series of amendments to Regulation No. 110, inserting new provisions for motor vehicles using Liquefied Natural Gas (LNG) in their propulsion system. During the last session, GRSG agreed to have a final review of the proposal.
39. Referring to ECE/TRANS/WP.29/2013/101, the expert from the Netherlands introduced ECE/TRANS/WP.29/GRSG/2013/28 clarifying the type approval provisions for vehicles equipped with Liquefied Natural Gas (LNG) propulsion systems. GRSG noted a list of editorial corrections (GRSG-105-02) to be inserted into ECE/TRANS/WP.29/2013/101. GRSG adopted the proposed amendments as reproduced in WP.29-161-05 and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2013 sessions as a Corrigendum to ECE/TRANS/WP.29/2013/101 (draft Supplement 1 to the 01 series of amendments to UN Regulation No. 110).

Preventing LNG fuel downstream of the vaporizer
49. Mr. Dekker: There are temperature sensors that can be used to detect temperatures lower than design temperatures of the components downstream of the vaporizer. This was raised by Andrew Whitehouse (CAP) during the last LNG Task Force teleconference also as one of the possible safety ‘systems’ that could be provided under the proposed amendment.
50. Mr. Piccolo noted that there is a concern temperatures downstream on non-LNG components. Mr. Whelan indicated that there are safety features to identify low temperatures that might affect, for example, a CNG solenoid valve. Also, too much cold fuel will shut down the engine.
Minimum height of LNG tank mounted on the truck
51. Mr. Dekker said that 200 mm should be the minimum height above the ground, taking into consideration things like traffic calming measures (also called ‘speed bumps’/’sleeping policemen’). What happens if the truck wheels are on either side of the speed bump and it comes in contact with a low-hung fuel tank?
52. Mr. Rijnders asked if the original Scania tank language said ‘shall’ or ‘or (in front of the container and/or tank shall not touch the ground if any tire or tires are deflated)’. The Dutch had prescribed 200mm and if it is lower there should be protection on the tank. Mr. Seisler indicated that the LNG TF had such a discussion and the solutions were too cumbersome.
53. Mr. Dekker asked if the 200mm shall be ‘from the lowest part of the tank.’ Mr. Seisler indicated that this comment would be raised in the next discussion of the LNG TF, scheduled for 16th December 2013.
