Abstract: A common rail fuel system diagnostic algorithm is executed by an engine control and real time to detect and identify a faulty fuel system component. Rail pressure data is processed through a digital resonating filter having a resonance frequency corresponding to a fault signature. A peak magnitude and phase of the output from the digital resonating filter reveals a degradation level of a fuel injector, and a phase of the output identifies which fuel injector is faulted.

Abstract: Methods and apparatus are provided for testing a fuel pump in a fuel supply system on a IC fuel injected engine, the pump having a pumping element for supplying fuel injectors via a fuel rail. The method includes providing a pump element pumping event; disabling overlapping injectors during a test-period that includes the pumping event; measuring pressure in the rail at least two engine crank angles surrounding the pumping event during the test period; and determining a fuel delivery rate value for the pump based on the measured rail pressures. Methods and apparatus also are provided for determining quantitative leakage rate in the fuel supply system of a fuel injected IC engine, the fuel system including a fuel pump with one or more pumping elements supplying injectors via a fuel rail. The method includes establishing steady state engine operating conditions with fuel rail pressure at a predetermined value; disabling all overlapping injectors and all pumping events during a test period; measuring rail pressure at preselected first and second crank angles during the test period, the first crank angle being advanced relative to the second crank angle; and calculating the leakage rate based on a pressure drop determined from the measured rail pressure at the first crank angle and the measured rail pressure at the second crank angle.

Abstract: A fuel control system for an engine is disclosed. The fuel control system may have a source of pressurized fuel and at least one injector configured to receive and inject the pressurized fuel. The fuel system may also have a sensor configured to generate a signal indicative of an actual fuel pressure at the at least one injector, and a controller in communication with the sensor. The controller may be configured to determine a desired fuel pressure at the at least one injector, and compare the signal to the desired fuel pressure. The controller may also be configured to initiate a leak detection sequence in response to the comparison.

Abstract: A system and method of controlling a fuel injector is provided. A first injection signal is applied to a hydraulically actuated fuel injector to inject a quantity of fuel into a combustion chamber of an internal combustion engine. An amount of an operating fluid used by the fuel injector to inject the quantity of fuel into the combustion chamber is calculated. The amount of fuel injected into the combustion chamber is estimated based on the amount of operating fluid used by the fuel injector. A viscosity parameter is determined for the fuel injector based on the duration of the first injection signal and the estimated amount of fuel injected into the combustion chamber.
