Abstract

In attempt to attain the best trade-off between performance and emission levels of a diesel engine fuelled with biodiesels, using CFD simulation using FIRE-code are performed. Initially, using the existing piston design, biodiesel fuel characteristics are entered to the model and compared with the conventional diesel fuel. Prediction of performance parameters, combustion characteristics, and emission levels are obtained. This is the focus of the present paper. Validation of the model by a dyno test is ongoing. Once the model has been validated, several different piston bowl configurations are simulated, including effects of operating parameters such as injection timing, injection pressures, and nozzle inclination angle. These are to be reported in the near future.
