This paper presents the process of designing, retrofitting and testing a compressed natural gas (CNG) fuel tank on a two-wheeler and operating the hybrid vehicle in solo modes as well as in hybrid mode. The study evaluates the viability of applying CNG as alternative source of energy in view of depleting conventional fossil fuels and performance of CNG fueled and CNG-petrol fueled two wheeler vis-à-vis conventional petrol engine two wheeler. The contribution of this research paper is design and integration of a custom-designed CNG Fuel Tank, ensuring compliance with safety standards and emission standards of Bharath Stage VI regulations. The CNG Fuel Tank is designed and installed in the most realistic position to prevent the vehicle from becoming unwieldy structure and several modifications were made to accommodate the CNG tank without compromising vehicle stability orperformance. The study concludes that CNG is a promising alternative to petrol for two- wheelers to attenuate green house gas emissions. The test results suggest that broader adoption of CNG in two-wheelers could contribute to more sustainable transportation besides superior fuel economy. The research findings will benefit the automotive industry community in their stride to attain zero emissions aimed at circumventing the ecological and environmental perils of global warming and ensuing climate change.
