The use of alcohol fuels in motor vehicles requires consideration of safety aspects relative to potential flammability , fire and explosion hazards. Pure methanol has a luminosity several orders of magnitude less than gasoline. In addition, the fuel/air mixture in the head space of a fuel tank containing pure methanol lies in the explosive region over a much wider temperature range than occurs with gasoline. Methanol fuels, however, frequently have additives blended with the methanol to increase volatility and to improve cold starting and cold driveability. A number of alcohol fuels have been selected for study which include methanol, gasoline (summer and winter grade), 5 % methanol/gasoline blends with cosolvent, 10 % ethanol blends, and 85-90 % methanol blended with various components such as butane, DME and gasoline. Physical properties of these fuels were determined and a hazard analysis was conducted using the data collected above. The analysis was limited to fire and explosion hazards in relation to vehicle systems including refuelling from service station pumps.
