A STUDY ON THE AUTOMOTIVE ENGINES FOR WATER-METHANOL BLENDS

Conventionally, studies on the automotive engines have been made only to improve engine performances with a given fuel. In considering the future energy situation and the requirement for pollution free operation, studies must be made to provide "better engines" with better fuel. This research is a series of systematical studies to determine the optimum application conditions of methanol expected to become one of the automotive fuels of the future. The following shows that automotive methanol engines are highly feasible for practical operations in the future. (1) oxides of nitrogen level can be reducedgreatly by adding water to methanol. (2) methanol is high in evaporation heat. This means that conventional engines, if used without modification, are reduced in thermal efficiency, driveability, startability and give out increased unburned methanol emissions. (3) thermal efficiency and unburned methanol level depend on fuel vaporization. Most disadvantages in methanol engines can be overcome by causing the methanol to vaporize completely. (4) fuel economy and pollution free operation can be achieved by means of a lean mixture of water and methanol and with a high compression ratio engine. /Author/TRRL/
