| 摘 要： | 柴油机催化转化器的转化效果依赖于催化剂的催化效果,而催化剂的催化效果和柴油机排气温度有很大的关系,柴油机在低转速、低负荷的工况下排气温度往往不能达到催化剂有效的工作温度。如何提高催化剂的工作温度,改善催化剂的催化效果是一个值得关注的问题,作者采用自制的电加热装置,用电加热的方式提高催化剂的工作温度以改善柴油机的排放,并且进行实际的发动机台架对比实验,对比加热前和加热后柴油机排放的变化情况,结果表明,对催化剂进行电加热后对排放改善的效果比较明显,尤其对于降低NO的排放效果比较明显。

| Abstract: | The transform effect of Oxidation Catalytic Converter(OCC) used on diesel engine depends on the catalyzer which depends on the temperature of the exhaust gas.The temperature of exhaust can not meet the effective work temperature of the catalyzer when the engine speed and the load are low.Some measures must be applied to increase the work temperature of the catalyzer.The work temperature of the catalyzer was increased by eletricity calefaction,and the emission of diesel engine was compared with that without ... |
