利用DEWE2010 DAQ数据采集系统测试了某柴油机燃用微乳化生物柴油的示功图,对实测示功图进行光顺处理后,分析了柴油机燃用微乳化生物柴油的压力、压力升高率和放热规律。试验结果表明,柴油机燃用微乳化生物柴油后,最高燃烧压力提高、放热始点推迟、着火延迟期增加。
The indicator diagram was measured with DEWE-2010 DAQ system on the engine fueled with micro-emulsified biodiesel. The actual indicator diagram was smoothed, and then the pressure, pressure rise rate and heat release rate of microemulsified biodiesel were analyzed. The experimental results show that the micro-emulsified biodiesel increases the maximum combustion pressure, and delays the heat release beginning, and extends the ignition delay.
