Abstract
The present invention provides a fuel system for an engine including a water supply source for providing water and a fuel supply source for providing fuel. A centrifugal pump is fluidly connected to the water and fuel supply sources, respectively at water and fuel inputs. The pump receives the water and the fuel from the inputs and produces a homogeneous mixture without using other pumps or mixing devices. A metering device is arranged between the pump and one of the supply sources, preferably the water supply source, to produce the desired ratio of water and fuel. The speed of the pump is varied to deliver the desired total volume and pressure of fuel and water to the engine through the pump output. The water metering device may be closed to deliver only fuel to the engine during special conditions such as engine startup and rapid load dumps. Operation of the system is simplified because only one pump and metering device is used.
