With increasing pollution concerns and stringent emission regulations, it has become difficult to meet the emission standards with the use of a single fuel. Binary and ternary fuel mixtures are being investigated all over the globe to satisfy the emission norms. In the present work, a reduced reaction mechanism for a waste cooking oil (WCO) biodiesel/n-pentanol mixture is proposed for the chemical kinetic simulation of an internal combustion engine. The mechanism consists of 146 species and 506 reactions. WCO biodiesel and n-pentanol are biofuels with many advantages. WCO biodiesel has properties (cetane number, viscosity, etc.) that are similar to those of diesel fuel, whereas n-pentanol has a high boiling temperature, low heat of vaporization, high lower heating value, and low autoignition temperature compared to other shorter chain alcohols. Mixing of higher molecular weight alcohols (n-pentanol) with diesel/biodiesel lowers the knock resistance as a result of their high reactivity at low as well as high temperatures. This characteristic makes them suitable for a diesel engine and advanced engine combustion modes, such as homogeneous charge compression ignition and reactivity controlled compression ignition engines.

用于内燃机模拟的废食用油生物柴油/正戊醇混合物的化学动力学机理降低

随着越来越多的污染问题和严格的排放法规，使用单一燃料已难以满足排放标准。为了满足排放标准，正在全球范围内研究二元和三元燃料混合物。在目前的工作中，提出了一种用于废烹饪油（WCO）生物柴油/正戊醇混合物的还原反应机理，用于内燃机的化学动力学模拟。该机制由146种和506个反应组成。WCO生物柴油和正戊醇是具有许多优势的生物燃料。WCO生物柴油具有与柴油相似的特性（十六烷值，粘度等），而n-戊醇与其他短链醇相比，具有较高的沸点温度，较低的汽化热，较低的发热量和较低的自燃温度。较高分子量的醇（正戊醇）与柴油/生物柴油混合会降低耐爆震性，因为它们在低温和高温下均具有高反应活性。此特性使其适用于柴油发动机和高级发动机燃烧模式，例如均质充量压燃和反应性受控的压燃发动机。
