Abstract
A piston engine is operated by pressurizing combustion air to a pressure above ambient pressure and adding water to the combustion air, and supplying the pressurized combustion air to which water has been added to a combustion chamber. An emulsion of fuel and water is sprayed into the combustion chamber. A desired rate of supply of water to the combustion chamber is determined and, in the event that the desired rate of supply of water changes, the rate of supply of water to the combustion chamber is adjusted by regulating the addition of water to the combustion air.
