This paper presents the rape seed oil methyl ester fueled combustion study undertaken on a supercharged, ceramic coated piston DI diesel engine investigating the combustion, performance and emissions production at a range of engine loads (IMEP), EGR levels and intake air boosting conditions. The utilization of EGR and intake air boost with biodiesel fuel combustion allows simultaneous NOx and particulate emissions reduction at conditions closer to on-road driving conditions. The results showed that while biodiesel can be favorable in reducing CO2 and particulate emissions, it causes an increase in NOx emissions when the intake energy contribution is increased. A reduction in the number of fine and ultrafine particles (diameter 0.05–0.2 μm) was observed when EGR was added to the engine, especially at the low and intermediate intake air boost levels. At high EGR levels (equivalent to 20% intake O2 concentration reduction) significant reductions in exhaust particulate mass of up to 75% were observed at 15% energy levels. An attempt was made to identify the optimum EGR operating window at the different engine loads, intake air boost levels. It was observed that the RME, ceramic coated piston with 15% EGR along with turbocharger reduces NOx emission to a significant value without rise in BSFC.
