Patent ID: 6845738

Claim:
A method for enriching working fluid of an internal combustion engine with moisture, the method comprising the steps of: starting a cyclic process of the engine; combusting at least one of a hydrocarbon-containing fuel and a hydrogen-containing fuel; passing the entire exhaust gas flow through a condenser arranged in the flow path of the entire exhaust gas; separating a first combustion water mass flow, resulting from the combustion of the fuel, from the exhaust gas of the engine; introducing the separated water mass flow into the working fluid of the engine at a suitable location; at least partially condensating and separating the combustion water mass flow that has been introduced and an additional combustion water mass flow from the exhaust gas; at least partially recirculating the combustion water mass flow that has been introduced and the additional combustion water mass flow into the working fluid of the engine; wherein the entire water mass flow originates from combustion water and from atmospheric humidity introduced with combustion air.
