摘要 燃油加入适量水燃烧特性会发生一定的变化,加入水量不同,燃烧特性改变程度有很大区别。加入水量越多,影响越大,影响时间也越长;不同种类燃油燃烧时受到水量影响程度也不同,通常含有相同水量时,柴油受到的影响较汽油要大。水温较低时,含水燃油燃烧的热释放速率、温度和烟气中CO2含量都较无水燃烧时有所降低,且柴油下降的幅度较汽油大。在低温燃烧时,含水汽油燃烧产物中CO含量较无水燃烧时低,高温燃烧时较无水时高;而含水柴油在低温和高温燃烧时,燃烧产物中CO都比无水燃烧时高。含水柴油的燃烧热释放速率和燃烧温度上升幅度较汽油大。 The combustion rule of oil with some water was different from pure oil,and the rule changes with the amount of water added into oil changing.The more the water added to oil,the more influence has on combustion.The effect of amount of water on different types of oil was also different,and the effect of water acting on diesel oil was more obvious than that on petrol oil.When the temperature of water in oil was low,the heat release rate(HRR),temperature and CO2 concentration in combustion product were all lower than those without water,and the drop of diesel oil with water was larger than that of petrol oil with water.For petrol oil,the CO concentration in combustion products of oil with water was lower than that of oil without water in low temperature,but higher than that of oil without water in high temperature.However,for diesel oil,the CO concentrations in combustion products of oil with water were always higher than that of oil without water in both low and high temperature.And the increase range of the heat release rate(HRR) and temperature for diesel oil were larger than that of petrol oil.
