The objective of this work is to reduce viscosity and other related problems associated with biodiesel by adding non polluting additives. Magnetite is chosen as an additive in this work. Significant reason for using magnetite as an additive is that the magnetic nano particles (magnetite) can be collected from exhaust using magnetic billets in the tail pipe. Performance and emission test is carried out in single cylinder compression ignition engine using base and modified fuel and is compared to diesel. Modified fuel consists of 98.5% base fuel (Rice bran oil methyl ester), 1.3% additives (magnetite) and 0.2% surfactant (tri methyl ammonium hydroxide) by volume. The experimental work confirmed that by adding magnetite to methyl esters of rice bran oil enhances the brake thermal efficiency by 4.27% with 5.17% reduction in SFC. In addition, 10.8%, 9.1% and 8.49% reduction in HC, CO and NOx emissions is observed respectively.

这项工作的目的是通过添加无污染的添加剂来降低与生物柴油相关的粘度和其他相关问题。选择磁铁矿作为这项工作的添加剂。使用磁铁矿作为添加剂的重要原因是，可以使用尾管中的磁性坯料从排气中收集磁性纳米颗粒（磁铁矿）。性能和排放测试是在单缸压缩点火发动机中使用基础燃料和改性燃料进行的，并与柴油进行了比较。改性燃料由98.5％的基础燃料（米糠油甲基酯），1.3％的添加剂（磁铁矿）和0.2％的表面活性剂（三甲基氢氧化铵）组成。实验工作证实，通过在米糠油的甲基酯中添加磁铁矿，可使制动热效率提高4.27％，SFC降低5.17％。另外10.8％，9。
