MMT对汽车尾气排放影响的调查统计分析

Investigation and Statistical Analysis for Infection on Exhaust Emissions by the Use MMT Fuel Additive Gasolines

对美国2002-2004年MMT对汽车尾气排放影响的600多组试验数据的调查统计结果表明:汽油中MMT含量为8.3mgMn/L时,含MMT燃油与不含MMT燃油在尾气排放方面相比,平均THC排放提高7.74%,CO无明显差异,NOx降低11.6%。在劣化率方面相比,THC劣化率提高118%,CO劣化率提高24.8%,NOx劣化率提高33.3%。含MMT燃油的3种主要污染物的三元催化转化效率均高于不含MMT燃油的相关值。

By processing and investigating automobile emission’s six hundred inspection data from the tests that infection on exhaust emissions from using MMT at a concentration of 8.3 mg Mn/L in USA between 2000-2004,The investigation and statistical analysis show that comparing with Clear-fueled vehicles,the averages for THC from MMT-fueled vehicles is greater 7.74%,CO is slightly greater and NOX is lower 11.6%.About deterioration rate of THC,CO and NOX is respectively greater 118%,24.8% and 33.3%.But TWC converter efficiency is generally greater than C1ear-fueled-vehicles.
