    摘要:

    分析了小桐子油的主要成分及理化性質(zhì)。以ZH1115型直噴柴油機(jī)作為試驗樣機(jī)，用不同比例的油料作為燃料，測量了氣缸壓力及NOx、HC、CO和煙度等廢氣排放，分析其負(fù)荷特性。燃用小桐子油與燃用柴油時相比，發(fā)動機(jī)氣缸壓力和壓力升高率，NOx、HC排放和排溫均較低，煙度相當(dāng)，只有CO排放略高。供油提前角提前時，燃用小桐子油的發(fā)動機(jī)氣缸壓力和壓力升高率增大， NOx排放量增加，排氣溫度略有降低，CO排放量變化不大，HC排放量減少。

    Abstract:

    The main components and properties of physics and chemistry of Jatrapha curcasl oil were analyzed. The characteristics of performances, combustion and exhaust emissions of a ZH1115 diesel engine using different fuels were measured. It is found that when the engine using Jatrapha curcasl oil, the cylinder pressure, the pressure rise rate, emissions of NOx and HC, and the exhaust temperature were all lower than using diesel, the smoke was at equivalent level; however, the CO emissions was higher. The cylinder pressure and pressure rise rate and its NOx emission increased, but when the advance angle of fuel supply increased, the exhaust temperature decreased a little, the CO emission had little change, and HC emission reduced.
