This manuscript presents the impact of addition of antioxidant additives to rice bran biodiesel blend on the performance and emission characteristics of compression ignition (C.I) engine. Rice bran methyl ester (RBME) was produced from rice bran oil by transesterification using sodium hydroxide as catalyst. An experimental investigation was conducted on a single-cylinder four-stroke C.I engine to analyze the performance and emission characteristics of rice bran methyl ester (RBME) blended with diesel at 20% by volume (B20) with and without addition of 1000 ppm of two monophenolic antioxidant additives, butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT). The results showed that the BHA- and BHT-treated B20 blend decreased the brake specific fuel consumption (BSFC) by 2.1 and 1.2% and increased the brake thermal efficiency (BTE) by 1.04 and 0.5% compared to B20. The BHA- and BHT-treated B20 blend produced mean reductions in NOx emission of 12.2 and 9.6%, respectively, compared to B20. The carbon monoxide (CO) and hydrocarbon (HC) emissions of BHA- and BHT-treated B20 were increased by 14.8-16.6% and 10.6-11.2%, respectively, compared to B20. However the emission levels were lower than those of diesel.
本文介绍了在米糠生物柴油混合物中添加抗氧化添加剂对压燃式（C.I）发动机性能和排放特性的影响。米糠甲酯（RBME）是通过碱催化的酯交换法从米糠油中生产的。在单缸四冲程 C.I 发动机上进行了实验研究，以分析米糠甲酯（RBME）与柴油以 20%体积混合（B20）时的性能和排放特性，以及添加 1000ppm 两种单酚抗氧化添加剂丁基羟基茴香醚（BHA）和丁基羟基甲苯（BHT）的情况。结果表明，与 B20 相比，BHA 和 BHT 处理的 B20 混合燃料的比燃料消耗（BSFC）分别降低了 2.1%和 1.2%，制动热效率（BTE）分别提高了 1.04%和 0.5%。与 B20 相比，BHA 和 BHT 处理的 B20 混合燃料的氮氧化物（NOx）排放分别平均降低了 12.2%和 9.6%。与 B20 相比，BHA 和 BHT 处理的 B20 混合燃料的一氧化碳（CO）和碳氢化合物（HC）排放分别增加了 14.8-16.6%和 10.6-11.2%。然而，排放水平仍低于柴油。
