Emission

Methanol-fueled vehicles emit less CO2 and other polluting gases com­pared to gasoline-fueled vehicles. Therefore, methanol use maintains good air quality. For a higher compression ratio compared to gasoline, a higher level of NOx can be achieved. But low flame temperature and latent heat of vaporization tend to decrease NOx emissions. The over­all effect is a lower level of NOx emissions.
