Effects of Different Biodiesel-Diesel Blend Fuel on Combustion and Emission Characteristics of a Diesel Engine

In this paper, biodiesel was used as an alternative fuel to investigate the combustion and emission characteristics of a four-stroke diesel engine, in terms cylinder pressure, heat release rate, temperature, brake thermal efficiency, specific consumption, nitrogen oxide, soot, carbon monoxide, hydrocarbon. Firstly, engine model developed by AVL-Fire software coupled with CHEMKIN code simulate injection kinetic mechanism 106 species 263 reactions. Then, simulation validated experimental results under 100% 50% load conditions process fueled pure diesel, biodiesel, biodiesel–diesel blends 10%, 20%, 30% volume, respectively. The showed that consumption increased increase mixed ratio. consumptions B10, B20 B30 1.1%, 2.3% 3.3%, respectively, compared D100. are improved. Therefore, can be for engine. diesel–biodiesel improve
