Abstract
A method is described for operating a spark ignition internal combustion engine utilizing an improved composition containing dimethyl ether and propane as fuel. An engine incorporating the invention produces a lesser amount of certain atmospheric pollutants, such as carbon monoxide and unburned hydrocarbons, as compared to the amount of pollutants produced when the engine is operated at identical conditions with propane as fuel. Also described is an improved fuel composition which exhibits a lower vapor pressure than, for example, propane and, therefore, is relatively easier to liquefy and transport.
