The purpose of this study is to conduct an experimental assessment of the impact of RCCI (reactivity regulated compression ignition) on the performance, emissions, and combustion of a CRDI engine. A fuel mix (20% biodiesel, 80% diesel, and a NaOH catalyst) is generated. The produced combination is evaluated for attributes using standards established by the American Society for Testing and Materials (ASTM). The engine research included three distinct kinds of injections: 10% Pen RCCI, 20% Pen RCCI, and 30% Pen RCCI. Increasing the injection pressure increases the brake thermal efficiency, often known as BTE. NOx emissions increased as a consequence of higher injection pressures and improved combustion. However, when the injection rate is increased, the Specific Fuel Consumption (SFC) falls. The CO and hydrocarbon emissions, as well as the smoke opacity values, increased as the charge increased. The resultant mixture may be utilized in a CI engine with pre-mixed ignition to improve overall engine performance as well as combustion characteristics.
本研究旨在对 RCCI（反应调节压缩点火）对 CRDI 发动机的性能、排放和燃烧的影响进行实验评估。生成燃料混合物（20%生物柴油、80%柴油和 NaOH 催化剂）。使用美国测试材料协会（ASTM）制定的标准对所生成的组合进行属性评估。发动机研究包括三种不同的喷射方式：10%Pen RCCI、20%Pen RCCI 和 30%Pen RCCI。增加喷射压力会提高制动热效率，通常称为 BTE。由于较高的喷射压力和改进的燃烧，NOx 排放量增加。然而，当喷射速率增加时，比油耗（SFC）会下降。随着负荷的增加，CO 和碳氢化合物的排放以及烟雾不透明度值都会增加。所得混合物可用于采用预混合点火的 CI 发动机，以提高整体发动机性能和燃烧特性。
