Optimization of Performance and Emissions of a Diesel Engine Fuelled with Rubber Seed- Palm Biodiesel Blends using Response Surface Method

摘要: The effects of engine speed and load, fuel blend ratio on the emissions performance an IDI (indirect injection) diesel were investigated. A 50:50 vol. rubber seed palm oils was used for biodiesel production to reduce costs enhance properties. Oil acid reduced from 33.4 1.42 mg KOH/g oil by esterification followed a transesterification in hydrodynamic cavitation reactor. Blends 0- 40 % with 10% increments prepared. Statistical tool, BBD (Box-Behnken design) based RSM (response surface methodology) assess combined variables parameters such as BT (torque), BP (power), BSFC (brake specific consumption), BTE thermal efficiency), CO, CO2, NOx, EGT (exhaust gas temperature) O2. load found be most influential parameter compared blend. have strong effect except less significant BSFC, BTE, CO CO2. On average blends showed lower (0.97- 1.6%), (0.94- 1.4%), (0.76-1.5%) (0.93-6.7%) but higher (0.93- 1.7%), CO2 (0.95- 1.1%), NOx 1.2%), (1.1- 1.3%) O2 (0.3- 1.2%) fuel. An optimum desirability value 0.96 achieved 18 (biodiesel diesel), 2320 rpm 82% tested engine.
