A cummins N14-410 engine was operated on 12 fuels produced by blending methyl tallowate, methyl soyate, and fuel ethanol with no. 2 diesel fuel. Engine in-cylinder pressure data were collected and used to evaluate the rate of heat release, mass fraction of fuel burned, and charge temperature with respect to crank angle. It was observed that the rate of heat release decreased with increasing engine speed. Peak rates of heat release for all fuel blends were less than for no. 2 diesel fuel. When methyl tallowate was blended with no. 2 diesel fuel, the shift in the location of peak heat release was away from top dead center (TDC) whereas the addition of ethanol to the blend shifted the location towards TDC. Ignition delay slightly decreased when methyl tallowate was blended with diesel fuel. However, ignition delays were not affected by the methyl tallowate content of the blend. The addition of ethanol to the fuel blends did not affect ignition delay. The charge temperature decreased with decrease in diesel content of the fuel blends. A reduction in charge temperature can reduce NO{sub x} emissions. 9 refs., 6 figs., 7 tabs.
