This report evaluates the results of admixing up to 20% of ethanol, from agricultural sources, with petrol. The exhaust emissions of carbon monoxide and hydrocarbons diminish as the ethanol content is increased, whereas nitrogen oxide emissions remain the same or increase slightly. The fuel consumption also increases but not to the degree to which the calorific value of the fuel is reduced. The vehicle driving behaviour was not found to be acceptable in all operating conditions even with the 5% blended ethanol fuel which is specified in the EC guideline 85/635 as the maximum recommnded fraction. This is a consequence of the reduced volumetric calorific value and the increase in the latent heat of evaporation.
