| 摘 要： | 在不同空燃比下,利用几种含有不同助催化剂的稀土催化净化器在汽机台架上进行了一系列试验,试验发现：空燃比对稀土三元催化剂在尾气中的CO,HC,NO和NOx净化效率有着明显的影响,尤其在稀混合气时,稀土三元催化剂具有较高的催化交,说明稀土元催化剂可以用于稀薄燃烧系统,此外,试验中发现转速和负荷对其净化效率有一定的影响。

| Abstract: | At different A/F ratio, using several kinds of rare-earth three-way catalysts with different aide-catalysts,a series bench tests were made. It was showed that A/F ratio had significant effects on the purification of exhaust emission , such as CO, HC, NO and NO X,the rare-earth three-way catalysts had higher purification efficiency especially with mixture gas in rare range, which showed that the rare-earth three-way catalysts could be used in the system of aerial combustion. The speed and load also had some effects on the purification efficiency. |
