摘要

这项研究的主要目的是在传统化石燃料之间进行替代,减少柴油发动机排放的温室气体和二氧化硫。在目前的研究中,为了减少NOx排放,EGR技术采用混合替代生物柴油,在5%、10%和15%的三种不同比例下,以20:1的最佳压缩比实施。研究结果表明,混合替代生物柴油在压缩比为20:1且满载时,BTHE为31.8%,EGR为10%。当EGR为15%时,混合生物柴油的峰值压力比没有EGR时低2.28%左右。当EGR增加时,点火延迟和NOx排放略有减少。只要EGR率增加10%,BSFC值就会有效降低。10% EGR的混合生物柴油可将废气温度降低至341℃。

Effects of exhaust gas recirculation on diesel engine using hybrid biodiesel
The primary aim of this study is to alternate between conventional fossil fuels and reduce the emissions of greenhouse gases and sulphur dioxide from the diesel engine. In the current study, in order to mitigate NOx emissions, the EGR technique was implemented utilizing hybrid alternate biodiesel at three varying proportions of 5%, 10% and 15% at an optimum compression ratio of 20:1. The findings demonstrate that for a hybrid alternative biodiesel at a compression ratio of 20:1 and fully loaded, the BTHE is 31.8% with 10% EGR. With 15% EGR, the peak pressure for the hybrid biodiesel is lower than it would be without EGR by around 2.28%. When EGR is increased, the ignition delay and NOx emissions are reduced slightly. With only an increase in EGR rates of up to 10%, BSFC values were reduced efficiently. The hybrid biodiesel with 10% EGR achieves a reduction in exhaust gas temperature to 341 ?C.
