生物柴油具有高粘度，这限制了其在发动机上的应用。然而，正戊醇具有低粘度和高挥发性，这被认为是一种有前途的添加剂。研究了正戊醇/生物柴油/柴油混合燃料在耦合废气再循环（EGR）（0-30%）条件下，对柴油机在不同负荷下性能和微粒排放的影响。三种测试燃料包括纯柴油（D100）; 80%柴油和20%生物柴油的混合燃料（BD 20）; 64%柴油、16%生物柴油和20%正戊醇的混合燃料（BDP 20）。结果表明，EGR对燃料间NOx排放的影响大于对燃料理化性质的影响。在相同EGR率下，随着发动机负荷的增加，放热率（HRR）、峰值缸内压力（IP）和制动器热效率（BTE）均增加。在BD 20中加入正戊醇后，HRR增加。BDP 20的IP和BTE峰值与D100和BD 20相似。随着正戊醇的加入，总颗粒数浓度（TPNC）、碳烟和总颗粒质量浓度（TPMC）排放降低。此外，TPMC和NOx之间的权衡关系得到改善，颗粒的几何平均直径（GMD）减小。
Biodiesel has a high viscosity, which limits its application to engines. However,n-pentanol has low viscosity and high volatility, which is considered a promising additive. This study examined the influence ofn-pentanol/biodiesel/diesel blends on the performance and particulate emissions of a diesel engine at different loads, under the condition of coupling exhaust gas recirculation (EGR) (0–30%). The three test fuels included pure diesel (D100); 80% diesel and 20% biodiesel blended fuel (BD20); 64% diesel, 16% biodiesel, and 20%n-pentanol blended fuel (BDP20). The results indicated that the influence of EGR on the NOx emissions between fuels was greater than that of the physicochemical properties of the fuels. For the same EGR rate, the heat release rate (HRR), peak in-cylinder pressure (IP), and brake thermal efficiency (BTE) increased with the engine load increased. After addingn-pentanol to BD20, the HRR increased. The peak IP and BTE values of BDP20 were similar to those of D100 and BD20. With the addition ofn-pentanol, the total particulate number concentration (TPNC), soot, and total particulate mass concentration (TPMC) emissions decreased. Furthermore, the trade-off relationship between TPMC and NOx was improved, and the geometric mean diameter (GMD) of the particles decreased.
