The present work proposes a new model for biodiesel combustion in an internal combustion engine. This model first includes the balance equations of gas dynamics with heat release. Secondly, a model with special properties that take into account turbulence effects is incorporated. The chemical models implemented in this study are for a biofuel used at less than 100% and for biodiesel-diesel blends. The resulting model is a coupling of equations describing the combustion of biodiesel with premixing. The model obtained is interesting and applicable to a wide range of combustion problems without major modifications. It is then proposed to the scientific community in order to develop internal combustion engines capable of meeting future political expectations regarding the reduction of pollutant emissions from the combustion of internal combustion engines.
