文摘
- •
The effects of EGR and blend fuels on particulate emission were studied in CI engine.
- •
EGR ⩽ 20%, gasoline or n-butanol increases total particulate number concentration.
- •
EGR ⩾ 30%, gasoline or n-butanol reduces total particulate number concentration.
- •
As EGR ratio increased, the particulate mass concentrations of four fuels increased.
- •
Gasoline or n-butanol increases the ratio of sub-25 nm particles number concentration.
