Abstract: An experimental study was conducted to evaluate the performance, emissions, combustion and heat release rate of an Indirect Diesel Injection (IDI) engine fuelled with Mahua methyl ester (MME) along with Methanol (M) additive blends. Smoke, NOx, CO, HC and CO2 emissions were recorded and various engine performance parameters were measured. A comparative study was conducted using diesel, MME and Methanol additive blends on an IDI engine. There is substantial improvement can be observed from the net heat and cumulative heat release rate plots in which the 3% additive blend reached the performance of diesel fuel and the corresponding cylinder vibration plots indicated smoother combustion. Five additive blends were tested, the blending ratios of 1/99, 2/98, 3/97, 4/96 and 5/95 (by vol.) and five discrete part load conditions viz. No Load, 0.77 kW, 1.54 kW, 2.31 kW, and 2.70 kW loads without gear box and clutch assembly ensuring stable engine operation. 57% HC, 20% CO, 14% NOx, 27% smoke reductions were observed at 3% additive at maximum opted load (2.70 kW and 1500 rpm) of the engine.
