(EN)

A fuel management system for using water for on-board vehicular separation of ethanol from ethanol-gasoline blends is described. Water or a water-alcohol mixture from a secondary tank is mixed with the ethanol-gasoline blend resulting in separation of the ethanol. By using on-board vehicular separation, the consumption of the externally supplied liquid from a secondary tank can be decreased to less than 1% of the gasoline consumption. This allows for long refilling periods for the externally supplied fluid. In another embodiment, a water-based fluid is directly injected into the cylinders of a spark ignition engine to eliminate knocking without causing misfire. In a further embodiment, an alcohol-based fluid is also used in those circumstances where injection of the water-based fluid may cause misfire.
