摘要：Dual fuel engine is internal combustion engine which works with two fuels simultaneously. Automobile sector is facing challenge of fossil fuel depletion & reducing harmful emissions to meet stringent environmental norms. Alternate fuels like CNG have capabilities of reducing exhaust emissions from automobiles.CNG has other advantages like lower cost as compared to gasoline & diesel, less noise due to high octane no & clean combustion properties. Diesel-CNG Dual fuel engines offer number of potential advantages like fuel flexibility, lower emissions, higher compression ratio and better efficiency. This paper is based on experimental work done on six cylinder turbocharged engine converted to dual fuel engine by using dual fuel kit from M/s Best Prins, Netherlands. Engine was tested on AVL PUMA engine testing system and emissions were measured on AVL emission measuring equipment. 13 mode ESC test was conducted in diesel mode & dual fuel mode. All points were optimized for engine performance & emissions. Optimized engine parameters & emissions were measured. It was observed that, it was possible to achieve engine performance near toBS III emission norms. Engine testing was carried out at ARAI, pune, India.
