Abstract: | Number concentration and size distribution from gasoline cars are investigated at transient modes on the chassis dynamometers,which are measured using electrical low pressure impactor (ELPI) for the ECE15 and EUDC cycles.Results indicate that,during cold start,particle number emission is higher than that under hot start.It is found that the number of particles increases with the vehicle speeds.Furthermore,particles with diameter smaller than 200 nm constitute the predominant part of total emission in the entire cycle.In addition,the tentative information about composition of emitted particles is also discussed. |
