Dekate, A., Nikam, S., Rairikar, S., Sreenivasulu, M. et al., "A Study on Material Compatibility with Various Blends of HCNG on Existing CNG Fuel Kit," SAE Technical Paper 2013-26-0079, 2013, doi:10.4271/2013-26-0079.
Natural Gas is one of the abundant fuel available on the earth and considered as a one of the cleanest fossil fuels. Most of the studies are conducted on CNG with different blends of hydrogen to improve the efficiency of engine and reduce the emission. However, components safety and its compatibility to these fuels were not studied in depth.Project was taken to understand material compatibility of CNG kit components and framing the National standards which can also be used for providing the inputs to international standards like ISO, ECE etc.Various components have been selected a sample base from CNG fuel kit for this study such as Refilling Valve, High Pressure Regulator and Gas Solenoid Valve, Rigid Pipe, low pressure flexible hose, etc. from renowned manufactures in the country and around the globe.The aim of the project was suitability of the CNG components for various blends of HCNGThe study was concentrated mainly on HCNG compatibility for non-metallic components and embrittlement test for metallic components.
