论文摘要
在这项研究中，使用KOH和NaOH催化剂与标准柴油燃料混合了由Crambe Abyssinica工厂生产的生物柴油燃料，并对发动机性能，燃烧和排放的影响进行了实验研究。标准柴油和6种不同的燃料混合物以3.75、7.5、11.25和15 nm发动机负载进行了测试。在实验过程中，根据每个测试燃料和发动机负载的曲柄角度指定缸内压力数据。此外，进行了HC，NOX，CO和烟雾排放的测量。通过获得的实验数据，计算并在MATLAB/SIMULINK环境中计算了并评估诸如热释放速率，燃烧率，热效率，指示的平均有效压力（IMEP），点火延迟（ID），振铃强度（RI）和特定的燃料消耗（SFC）。已经发现，与koh catalyst（CAK）混合燃料系列相比，所有发动机负载的浓缩Crambe Abyssinica与NaOH催化剂（CAN）混合燃料系列相比，在所有发动机负载下的BSFC值较低。得出的结论是，在所有发动机负载条件下，用CAK B25混合燃料实现了最高的热效率值。得出的结论是，标准柴油燃料的使用比其他混合物更容易敲门。
In this study, biodiesel fuel produced from crambe abyssinica plant using KOH and NaOH catalysts was mixed with standard diesel fuel and the effects on engine performance, combustion and emission were experimentally investigated. Standard diesel fuel and 6 different fuel mixtures were tested at 3.75, 7.5, 11.25 and 15 Nm engine loads. During the experiment, in-cylinder pressure data were specified depending on crank angle for each test fuel and engine load. In addition, measurements of HC, NOx, CO and smoke emissions were carried out. With the obtained experimental data, parameters such as heat release rate, combustion stages, thermal efficiency, indicated mean effective pressure (imep), ignition delay (ID), ringing intensity (RI) and specific fuel consumptions (SFC) were calculated and evaluated in MATLAB/Simulink environment. The same concentrated crambe abyssinica with NaOH catalyst (CAN) blended fuel series has been found to have a lower BSFC value at all engine loads than the crambe abyssinica with KOH catalyst (CAK) blended fuel series. It was concluded that the highest thermal efficiency values were achieved with CAK B25 mixed fuel under all engine load conditions. It was concluded that the usage of standard diesel fuel is more prone to knock than other blends.
