Transesterified fuels (biodiesel) from vegetable oils are alternative fuels for diesel engines. They are renewable and offer potential reduction in CO and HC emissions due to higher O2 contents in vegetable oil. Many research studies have reported that exhaust from biodiesel fuel has higher NOx emissions while HC and PM emissions are significantly lower than operated with diesel fuel. The aim of the present investigation is to reduce NOx emissions. Exhaust gas recirculation (EGR) is one of the most effective techniques for reducing NOx emissions in compression ignition engines. A Single cylinder four stroke water cooled direct injection (DI) diesel engine was used for conducting test with (Palm methyl ester: PME) biodiesel blends with diesel fuel combined with EGR technique. The results showed that for a 7.5kW power output, B10 and B20 PME with 8% EGR rate produce less NOx emissions compared to diesel fuel for the same level smoke emissions.
