Abstract

An internal combustion engine system for automotive vehicle wherein liquid water is produced by cooling a portion of exhaust gases at elevated pressure to induce condensation. The use of elevated pressure allows condensation to occur at a higher dew point which is easier to realize with cooling by ambient air. Liquid water condensate is collected and provided to an electrolytic cell for electrolysis into gaseous hydrogen and oxygen. Hydrogen gas generated by the cell is used by the internal combustion engine to reduce internal combustion engine wear and to reduce exhaust pollutants especially during start-up. Alternate uses of the liquid water include a replenishment of engine coolant and window washing fluid.
