Abstract
According to the stage 4 emission standard of GB 18352.3-2005, comparative studies on particles, aldehydes and ketones emitted from a gasoline vehicle fueled respectively with E10 ethanol gasoline and gasoline were conducted. Particles were measured by electrical low pressure impactor (ELPI). Aldehydes and ketones were measured through high performance liquid chromatography (HPLC). The results show that particle number, area and volume concentrations for E10 are all lower than those for gasoline. Aldehydes and ketones for E10 are higher than those for gasoline, with acetaldehyde increasing five times. When gasoline was fueled 99.98% of particles belong to PM2.5 and 95.79% of particles are PM0.1.When E10 was fueled, ratios are 99.99% and 95.33% respectively.
