Combustion characterization in a single cylinder engine with mid-level hydrated ethanol-gasoline blended fuels

- The amount of water seems to be less important than the fact that water is present.
- NOx emissions seem to decrease as the water content in the fuel increases.
- Differences in fuel consumption between anhydrous and hydrated ethanol are higher as ethanol contents increase.
- Water slows the combustion process releasing the same amount of heat, but more efficiently.
