- •
Effect of compression ratio and fuel on combustion and PM was investigated.
- •
Compression ratio increase improved indicated efficiency.
- •
Ethanol addition to gasoline significantly reduced NOx and HC emissions.
- •
1-butanol addition to gasoline significantly reduced PM emissions.
- •
Synergies between alcohol & compression ratio improved efficiency & emission control.
