Abstract
Disclosed is a system comprising a mixing tank, a methanol supply unit, and a water supply unit. When it is detected by first and second level sensors that the mixture liquid stored in the mixing tank and the liquid fuel stored in the methanol supply unit are in not more than predetermined amounts respectively, water supply is stopped from the water supply unit to the mixing tank in accordance with the action of a changeover valve. Accordingly, it is possible to always maintain a constant mixing ratio of liquid fuel and water in the mixing tank, and it is possible to simplify the system.
