Changes in UNECE 110 regulation

Some significant changes were introduced recently that will affect the approval of vehicles powered by liquefied natural gas (LNG). Those changes will allow the approval of LNG-powered cars in accordance with UNECE regulation 110.

The amended document comes into force in July 2014. This means that countries whose domestic legislation is based on this document must adapt to new requirements.

Despite the explicit reference to Europe, UNECE’s regulations have a global impact on the market of vehicles powered by gaseous fuels, because more than 50 countries outside Europe bases their regulations on these provisions.

The text of the regulation was amended and approved to include the requirements for LNG. This process has been endorsed by industry experts, who have prepared all necessary changes. This group of experts included specialists from Europe’s and America’s most important manufacturers of components of LNG systems, as well as car manufacturers. They were supported directly by NGVA Europe and NGV Global.

In addition to safety requirements for LNG systems installed in cars (tanks, evaporators, pressure regulators, valves, pipes, fittings, etc.), this regulation also contains requirements for LNG tanks associated with fuel storage. After filling up, the tank must be able to store liquefied natural gas for at least 5 days (without dropping out the excess that is associated with LNG evaporation).

UNECE regulation 110, which is a list of safety requirements and testing procedures that apply to gas-powered vehicles, forms the basis of operation for the gas industry around the world, both in terms of car conversions, as well as for manufacturers of new vehicles powered by natural gas.
