| 概要 |
Biofuel plays a predominant role in the sustainable growth of any developing country due to its renewability and lower toxicity. This led the researcher to work on alternative fuels. In this aspect, S...ample 1 consists of a composition comprising 50% by weight of raw karanja (pongamia) oil, 25% by weight of raw animal fat (beef tallow) oil, and 25% by weight of cooked oil. On the other hand, Sample-2 comprises a composition consisting of 60% by weight of crude karanja oil, 20% by weight of raw beef tallow oil, and 20% by weight of cooked oil. Biodiesel blends are investigated for their optimization and performance through diesel engines. Optimization is performed using RSM, with yields of 98.32% and 97.82% obtained for samples 1 and 2, respectively. The optimized conditions were maintained as 8.15:1 methanol-oil ratio, 1.2 wt.% catalyst concentrations, 75 min. of reaction time, 64°C temperature, and 6.74:1 methanol-oil ratio, 1.193 wt.% catalyst concentrations, 74 min of duration, and 64°C temperature for samples 1 and 2, respectively. The sample properties meet the ASTM D6751 standards. Both the samples are blended with the diesel in an appropriate ratio, and the performance tests are conducted in a single-cylinder diesel engine at variable workload conditions. The brake thermal efficiency obtained for sample 2 is higher than that of sample 1. At B100, sample 1 had 27% of BTE, whereas sample 2 had 29%. The BTE of B20 blends in samples 1 and 2 is 31.5% and 33%, respectively. The brake-specific fuel consumption for samples 1 and 2 at B100 blend ratios is 1.45 kg/kWh and 1.4 kg/kWh, respectively.続きを見る
