Abstract
Regulated and unregulated emission of a gasoline vehicle that meets national standard No.III and fuelled with methanol were investigated. Thermal desorption-gas chromatography/mass spectrometer (TD-GC/MS) was used for aromatic compounds emission and high pressure liquid chromatography (HPLC) was used for aldehyde and alkone emission. Test results showed that THC, CO and NOx emission from the methanol vehicle were less than the case using gasoline, but the aldehyde and alkone emission appeared higher than the gasoline vehicle, especially its formaldehyde emission is six times than the gasoline vehicle, but the volatile organic compounds (VOCs) emission amounted to only half that of the gasoline emission.
