| description | Harmful emissions and carbon dioxide emissions from diesel fossil fuels are one of the reasons for limiting the use of this fuel for automotive transport in some countries around the world. Therefore, the use of biodiesel in the internal combustion engine of motor transport is an urgent task. For better combustion of biofuels, it is necessary to investigate the ignition delay of this fuel. The paper proposes modeling of ignition delay of diesel biofuel by means of two equations of the Arenius type depending on the temperature range. For low and medium temperatures, the ignition delay depends on the type of fuel, so the equation includes the cetane number of fuels. For high temperatures, as a rule, the ignition delay does not depend on the type of fuel. To simulate the combustion process, real biofuel is replaced by one component or a mixture of several components. These are methyl decanoate (methyldecanoate C11H22O2), the acid of which has ten carbon atoms (C10:0M) and two methyl esters with one double bond, located in different positions of the aliphatic main chain: methyl-5-deceonate (C10:1M5) and methyl-9-deceonate (C10:1M9). Ignition delay modeling of diesel biofuel components used for fuel combustion modeling is performed. Ignition delay studies (C10:1M9) have shown that this ether is not suitable as a component of a diesel biofuel surrogate due to its similar reaction activity with (C10:0M). A good agreement between the theoretical values of ignition delay and experimental data is obtained.As a substitute for diesel biofuel in the problems of modeling the combustion of biofuels in internal combustion engines can be used surrogate fuel with 41,18 % n-decane, 9,41 % (C10:0M) and 49,41 % (C10:1M5). The study of ignition delay of such a surrogate fuel may be the subject of further research. |
