Abstract
A method of delivering fuel to an engine during operation of the engine, that includes, sensing the speed of sound in the fuel, determining a density or property of the fuel, and based on that density or fuel property adjusting the flow rate of the fuel. Further, an established fuel profile or determined energy density value can also be used to adjust the flow rate of the fuel.
Claims18
A method of adjusting a flow rate of fuel to an engine during operation of the engine, the method comprising:
- sensing a speed of sound in the fuel being delivered to the engine during operation of the engine;
- determining a density of the fuel based only on the sensed speed of sound during operation of the engine and a bulk modulus value for the fuel;
- and
- adjusting the flow rate of the fuel being delivered to the engine during operation of the engine based on the determined density.
A method of adjusting a flow rate of fuel to an engine during operation of the engine, the method comprising:
- sensing a speed of sound in the fuel being delivered to the engine during operation of the engine;
- determining a bulk modulus value for the fuel;
- determining a density of the fuel based only on the sensed speed of sound and the bulk modulus value during operation of the engine;
- and
- adjusting the flow rate of the fuel being delivered to the engine during operation of the engine based on the determined density.
