Abstract

This present work deals with the effects of injection parameters such as pilot-main injection mass ratio and dwell time on combustion, performance, and emission characteristics of a diesel engine. A single cylinder diesel engine is used in this research work with the flexibilities to modify different variables via open electronic control unit. Biodiesel mix (BDM) used in the present work is derived from waste feedstocks of used cooking oil and chicken fat. Throughout the experiment, engine load and speed were maintained constantly at 4.51 brake mean effective pressure and 1500 rpm, respectively. Different pilot mass ratios (10%, 20%, and 30%) and dwell times (20° crank angle (CA), 30° CA, and 40° CA) were tested and results were compared with conventional mode combustion. The results indicated that the pilot injections helped to reduce the ignition lag period and also shortened the combustion duration. The highest brake thermal efficiency of 34.78% was identified with the lowest pilot mass of 10%. According to the results, increased dwell time decreased the oxides of nitrogen emissions but increased the hydrocarbon emissions. The experiment revealed that BDM made of waste feedstocks could be an effective alternative for engine applications with optimized engine operating conditions.

喷射参数对装有CRDI的固定式柴油机燃用来自废弃原料的纯生物柴油混合物的影响

本文研究了引燃主喷射质量比和停留时间等喷射参数对柴油机燃烧、性能和排放特性的影响。本研究使用了一台单缸柴油机，通过开放式电子控制单元可以灵活地修改不同的变量。本工作中使用的生物柴油混合物（BDM）来源于用过的食用油和鸡脂肪的废弃原料。在整个实验中，发动机负载和转速分别恒定地保持在4.51制动平均有效压力和1500rpm。测试了不同的引燃质量比（10%、20%和30%）和停留时间（20°曲轴转角（CA）、30°CA和40°CA），并将结果与传统模式燃烧进行了比较。结果表明，引燃喷射有助于缩短点火滞后期，也缩短了燃烧持续时间。最高的制动热效率为34.78%，最低的先导质量为10%。根据结果，停留时间的增加减少了氮氧化物的排放，但增加了碳氢化合物的排放。实验表明，在发动机运行条件优化的情况下，由废弃原料制成的BDM可能是发动机应用的有效替代品。
