Compressed Natural Gas Fuel Composition Issues 931828
This paper reviews the gas industry's efforts to establish new and revised standards and specifications for natural gas vehicle (NGV) fuel systems; fueling stations; storage containers; fueling nozzles; and gas composition. The primary focus of the paper is NGV Coalition's Gas Composition Subcommittee and the Society of Automotive Engineers' Fuels and Lubricants Technical Committee work on Recommended Practice J1616. Fuel concentration limits recommended in J1616 are discussed, and plans for further investigation are outlined.
