In order to reduce the harmful effect on the environment, using the oxygenated fuels such as biofuel blends as fuel has been on the spotlights for the internal combustion engines. For this rationale; the diesel engine operated with blends of sunflower biodiesel and diesel fuel (blending of 0%, 10%, 20%, and 100% biodiesel fuel with conventional diesel fuel). In this study, an experimental and numerical model for Heat release rate (HRR) and the characteristic performance of diesel engine such as cylinder pressure and emission characteristics (NOx, CO, and HC) in internal combustion engines is presented. To ensure the integrity of modeling, the results were compared with the experimental results. This comparison indicated a good agreement between the two. A Gaussian and Fourier series of second order was used to define a function relating the pressure and emission characteristics. Presented numerical model, implemented in proprietary software AVL FIRE, is able to capture chemical phenomena and to predict pollutant emission concentration trends. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1540–1550, 2018
