Proposal for amendments to Regulation No. 110 - CNG compressor
Document GRSG-113-25
4 October 2017

Proposal for discussion to enable the certification of CNG compressor components. Due to density and temperature constraints, LNG fuel systems require technologies to warm the LNG fuel to reach temperatures and pressures suitable for the engine. In some configurations, this involves the use of CNG compressors. Therefore, this proposal seeks to enable use of this technology through establishment of requirements to ensure safety.
