Modeling of Compression Engines Using Biodiesel as Fuel

A single zone C.I engine model has been developed in an in-house code that would be suitable for conventional diesel as well as for alternative fuel (biodiesels), to predict the pressure and temperature variation along crank angle, work done, mean effective pressure, power output and other engine parameters suitable for biodiesel. The model has been validated with the experimental results. Performance of the diesel engine depends on injection timing, delay period as well as the duration to get complete combustion are presented and discussed. The indicated and brake work done obtained are 13.20 kJ/cycle and 10.52 kJ/cycle respectively for B100 and the indicated and brake specific fuel consumption obtained are 0.289 kg/kWh and 0.362 kg/kWh.
