摘要
MMT作为一种无铅汽油抗爆剂得到了广泛的应用,它可以提高发动机抗爆能力,从而提高车辆的动力性能而降低油耗,但是MMT会对排放造成一定的影响。笔者对一辆使用含MMT的汽油,行驶里程为5万公里,排放满足国Ⅲ标准的车辆进行试验。试验结果表明:MMT使得三元催化转化器劣化,造成CO、HC和NOx排放量增加;使得氧传感器劣化从而导致NOx排放量增加。
MMT had been used widely as an antiknock additive in petrol.It can enhance the vehicles dynamic performance and reduce fuel consumption,but cause some negative impact on vehicle emissions.In this paper,the authors research on the emission performance of a vehicle that meets Stage III emission standard using gasoline containing MMT and has run for 50,000 km.The test results show that emission pollution such as CO,HC and NOx increased by MMT that results in three-way catalytic converter deteriorated quickly.MMT also made the oxygen sensor deteriorate and caused high NOx emission.
