The purpose of this paper is to study the possibility of practical Use of gasoline-methanol mixed fuel as an alternative fuel of gasoline engines jn the light of engine performances and harmful exhaust emissions as well as mixings and separations of the mixed fuels.
When the methanol of 99.8% purity is mixed with super or regular gasoline available on the market today, the experimental results obtained without modifying carburetor in this study are as follows;
1. The separation ratio depends upon the gasoline-methanol mixing ratio only, regardless of fuel temperature and fuel additives for preventing separation of phase.
2. The critical absorption ratio is affected by the gsoline-methanol mixing ratio, its temperature and the quantity of fuel additives.
3. Concerning the distillation temperature, the initial point of all sorts of fuels is almost same, but 10% point and 35-60% point of mixed fuels are lower than those of gasoline only.
4. In case of throttle valve opening set, engine output using the mixed fuels is decreased compared to gasoline, but thermal efficiency is increased as a consequence of decreasing speci-
fie energy consumption.
5. In case of fixed load test, thermal efficiency is increased at low engine speed even under low part-load as well as under comparatively high part-load including full load.
6, CO and NOx emissions are reduced remarkably with the mixed fuels.
