(US5697987-A)      The spark ignition motor fuel composition comprises: (a) a hydrocarbon component which is 4-8C alkane(s) free of olefins, aromatics and sulphur, the component having a minimum anti-knock index of 65 as measured by ASTM D-2699 and D-2700 and a maximum dry vapour pressure equivalent (DVPE) of 15 psi as measured by ASTM D-5191; (b) fuel grade alcohol; and (c) a cosolvent miscible in both hydrocarbon component and the alcohol. The components are present in amounts effective to provide a motor fuel with minimum antiknock index of 87.    Also claimed is a process for lowering the vapour pressure of a hydrocarbon-alcohol blend involves blending the alcohol and hydrocarbon(s) with a cosolvent as above.    USE -   Used as spark ignition motor fuels for internal combustion engines.    ADVANTAGE -   Fuel based on coal gas liquid or natural gas liquids has lowered vapour pressure and improved antiknock index. The composition reduces emissions of carbon monoxide and hydrocarbons with no significant increase in fuel consumption.
