Combustion characteristics, performances and emissions of a biodiesel-producer gas dual fuel engine with varied combustor geometry

摘要: Abstract This paper presents the overall performance, emission and combustion characteristics of engine, when fuelled with biodiesel blends Calophyllum Inophyllum methyl ester as injected fuel babul wood chip derived producer gas inducted at constant injection timing (230bTDC), pressure (230 bar) speed (1500 rpm). To improve reduced chamber was varied 5 different geometries. Experimental results revealed that Toroidal re-entrant had higher Exhaust Gas Temperature Brake Thermal Efficiency by 20.75% 6.37% than HCC, while Specific Fuel Consumption 4.49% optimal loading condition. However, engine performance TrCC found to be comparable Hemi-spherical other designed chambers. Similarly, comparing exhaust emissions, Oxide Nitrogen Carbon dioxide were on its side 19.90% 27.20% normal HCC. On contrary, carbon monoxide, Hydrocarbon Smoke opacity for 76.12%, 33.71% 38.67% lower From above study, it is finally concluded converted renewable fuels might utilized an alternative without any related problems.
