Title:Recommended Practice for Compressed Natural Gas Vehicle Fuel
Issuing Committee:Fuels And Lubricants Tc 7 Fuels
Scope:Compressed Natural Gas (CNG) is a practical automotive fuel, with advantages and disadvantages when compared to gasoline. it has a good octane quality, is clean burning, easy to meter, and generally normally compressed form 20 690 to 24 820 kPa (3000 to 3600 psig) to increase its energy density thereby reducing its on-board vehicle storage volume for a given range and payload.the properties of natural gas are influenced by (1) the processing of natural gas by the production and transmission companies and (2) the regional gas supply, storage, and demand balancing done by distributuion companies often in concert with pipeline companies to maintain uninterrupted service throughout the year, e.g., peakshaving the propane-air (see U.S. Bureau of Mines Publication 503).This document presents the more important physical and chemical characteristics of compressed natural gas vehicle fuel and describes pertinent test methods for defining or evaluating these properties. In order for compressed Natural Gas Vehicles (NGVs) to effective provide satisfactory and safe operation for users, there is a need to address specific issues relative to the use of natural gas as a vehicle fuel. The two primary areas relate to 1) compressed storage of natural gas and 2) vehicle fuel system and engine performance issues. These provisions have been derived through a joint effort of the SAE TC-7 Natural Gas Vehicle Task Force and the Technology Committee on the Natural Gas Vehicle Coalition.【英文标准名称】:StandardSpecificationforAsphaltShingles(OrganicFelt)SurfacedWithMineralGranules
