In the past few decades CNG (Compressed Natural Gas) fuel growing as an alternate fuel due to its more economically as compared to Gasoline & Diesel fuels by vehicle running cost in both passenger as well as commercial vehicles, additionally it is more environment friendly & safer fuel with respect to gasoline & diesel. At standard temperature & pressure fuel density of Natural Gas (0.7-0.9 kg/m3) is lower than Gasoline (715-780 kg/m3), Diesel (849~959 kg/m3), therefore CNG fuel require higher storage space as compared to Gasoline & Diesel & also it stores at very high pressure (200-250 bar) to further increase the fuel density 180 kg/m3 (at 200 bar) and for 215 kg/m3 (at 250 bar) in CNG cylinders so that max fuel contains in the cylinders and increase the vehicle running range per fuel filling & reduces its fuel filling frequency at filling stations. Therefore to gain max vehicle running range in a single fuel filling, NGVs (Natural Gas powered vehicles) require more numbers of CNG cylinders especially for commercial vehicles (Buses & Trucks) segment to store CNG with its cylinders which is also increase the fuel filling time. So as increase fuel capacity on vehicle it also increase the fuel filling time proportionally & impact indirectly on vehicle running cost in commercial vehicle segments for our valued customers. Therefore in further reduction of fuel filling time for NGVs, through this paper Author presenting design Implementation & correction as per result obtained by Computational fluid dynamics (CFD) analysis for reduction CNG fuel filling time in NGVs.
