摘要

在以废食用油(WCO)生物柴油为燃料的3.5 kW四冲程柴油机上，研究了停留角和两级加油方式对发动机效率和尾气排放的影响。以单缸高压CRDi柴油机为实验对象，在5°CA和10°CA两种不同的停留角下，在600 bar的燃油压力下，先导燃油量分别为10%和20%，进行了试验。结果表明，当B20P20先导加油时间为28°bTDC时，停留角和两级加油技术的联合作用使B20P20的BTE提高了8.13%，而当B20P20先导加油时间为33°bTDC时，BSFC降低了。与B20P20在28°bTDC的PFT相比，在33°bTDC的PFT, CO、HC和烟雾排放量分别下降了72.72%、37.04%和93.75%。在所有测试样本燃料中，氮氧化物的减少量不受两阶段加油策略的影响，生物柴油混合物的氮氧化物减少量明显高于矿物柴油。

Effect of Dwell Angle and Two-Stage Fueling Approach on the Engine Parameters of CRDi Engine using WCO Biodiesel Blends

In this paper, the impact of dwell angle and two-stage fueling technique on engine efficiency and tailpipe emissions in a 3.5 kW powered four-stroke diesel engine fueled with waste cooking oil (WCO) biodiesel blends were investigated. An experiment with single-cylinder high-pressure CRDi equipped diesel engine was executed at two different dwell angles (5° CA and 10° CA) with varying pilot fueling quantities of 10% and 20% at nozzle fueling pressure of 600 bar. The outcomes revealed that the combined effect of dwell angle and two-stage fueling techniques had enhanced the BTE by 8.13% for B20P20 pilot fueling timing (PFT) of 28° bTDC, whereas BSFC lowers for B20P20 blend at pilot fueling timing of 33° bTDC. Comparing B20P20 PFT at 28° bTDC to PFT at 33° bTDC, CO, HC and smoke emissions drop by 72.72%, 37.04%, and 93.75%, respectively. The nitrogen oxide reduction is unaffected by two-stage fueling strategy among all the test sample fuels and significantly higher for the biodiesel blends than mineral diesel.
