5. Constraints specific to natural gas engines

The various characteristics mentioned below were presented in the article Natural gas. Fossil energy [BM 2 591] .

5.1 Characteristic variations: PCI, RAFST, methane index

The diversity of supplies and the emergence of the possibility of re-injecting biomethane into the network are leading to increased variability in the composition of natural gas on the network, and therefore in its physical and chemical characteristics. These variations will therefore have potentially...
