Abstract: In this work, theoretical and experimental studies about the effects of the blends of diesel and palm oil biodiesel on NOx formation in compression-ignition engines were developed. Experiments were conducted using commercial diesel, palm oil biodiesel and blends at 5% (B5), 20% (B20) and 50% (B50) as fuels. A phenomenological semi-empirical model that uses the information obtained from thermodynamic diagnostics was used for determining the theoretical NOx formation. The model shows the high sensitivity of NOx formation to the temperature and the operating conditions. Effects associated to the operating conditions of the engine were evaluated and the results indicate that high engine loads and low speeds lead to the NOx formation. However, it was not possible to determine with precision, the effect of the type of fuel, because of the high sensitivity of the NOx formation with respect to the operating conditions of the engine.
