In order to improve efficiency and to reduce the atmospheric pollutants emitted by internal combustion engines it is worthwhile to assess the suitability of clean burning fuels. methanol and ethanol offer the most promising substitutes for petroleum as engine fuels at present (1). Compression ignition engine cannot be run on straight methanol because of its poor ignition quality. Use of methanol - diesel solutions is also impracticable because methanol is almost
insoluble in diesel. Inspite of these difficulties, there are many methods available to supplement methanol into the diesel engine(3). By means of carburetor similar to gasoline
engine. Low pressure injector to inject methanol at intake manifold continuously.
Low pressure injector very near to the intake valve and methanol was inducted during valve
opening period.
