Abstract:The pollutants were detected from tail gas after Vehicles used the ethanol gasoline under idling condition. The result showed that the contents of carbon monoxide and hydrocarbon decreased remarkably, and the average rates were 56.9 % and 38.2% separately, the NOx dropped 15.0 % , average growth rate of the carbon dioxide was 5.04% , the contents of aromatic compounds fell from 45.5% to 53.1%. The content of aldehydes increased obviously and average growth rates in 47.8 % - 293 % , the average growth rates of acetone and butanone increased 16.6 % and 25.3 % respectively.
Keywords:Ethanol gasoline  Gasoline  Vehicle  Pollutants  Exhaust
