PERFORMANCE AND EMISSION ANALYSIS OFA MULTI CYLINDERC.I. ENGINE FUELED WITH DIESEL-CNG DUAL FUEL

Abstract

The smoke is the main problem in the diesel engines. One of the main reasons of increased level of air pollution is transportation vehicles. Diesel engine produces harmful gases like carbon monoxides, nitrogen oxides, unburnt hydrocarbon, smoke, soot and particulate matter which are harmful to the environment and human kind. The environmental pollution can be controlled by utilization of alternative fuels such as Biodiesel and CNG (Compressed Natural Gas). In this project the performance testing of Biodiesel and diesel-CNG dual fuel is done on CI engine and the results were compared with performance of pure diesel. The project work was carried out on a 44.5 kW fourstroke, four-cylinder, Tata Indica diesel engine which was converted into dual fuel mode by substituting the CNG in the intake of suction pipe with the help of air mixer. Engine was operated in dual-fuel mode with substitution of diesel with CNG. The performance and emission characteristic of the engine were compar...
