Abstract:
An assembly comprising:a plurality of fuel injectors; a source of fuel; a first member which is coupled to said source of fuel and to said plurality of fuel injectors; a second member which is coupled to a source of voltage, said source of voltage providing a certain amount of voltage, said second member being further coupled to said source of fuel and to said first member, and said second member causing at least some of fuel which is resident within said source of fuel to be communicated to said first member, thereby creating a certain pressure within said first member; and a controller which is coupled to said second member and to said plurality of said fuel injectors, said controller storing a plurality of fuel pressure to fuel flow rate relationships over a range of voltages, wherein said controller measures said certain amount of voltage and calculates a desired fuel flow rate and is effective to infer said certain pressure within said first member using only a unique one of said plurality of relationships which corresponds to said certain amount of voltage; wherein said controller uses said inferred certain pressure to adjust an activation time interval for said plurality of fuel injectors.
