    • A system (12) and method for determining a value for a control variable for an engine (10) are provided. The system (12) includes an electronic control unit (ECU) (62) configured to obtain a plurality of pairs of programmed timing values for the opening and closing, respectively, of an intake valve (30) and exhaust valve (32) in a cylinder (14) of the engine (10) responsive to different sets of engine operating conditions. The ECU (62) is further configured to obtain a corresponding plurality of conditional values for the control variable responsive to the speed of, and load on, the engine (10) and the plurality of pairs of programmed timing values. Finally, the ECU (62) is configured to determine through interpolation the value for the control variable responsive to the plurality of conditional values. The system and method enable accurate determination of engine control variables during transient conditions using existing engine data.

    • A method of controlling the power output of an internal combustion engine having at least one fuel injector responsive to a commanded fuel signal. The method includes the steps of determining a desired engine power, and determining a first fuel flow value as a function of the desired engine power and engine speed. This first fuel flow value is then compared to the desired fuel flow signal generated by the air-fuel ratio controller. The commanded fuel signal is then limited by the lesser of the desired fuel flow and first fuel flow value. In one aspect of the invention, the desired engine power is calculated by determining a first power value as a function of engine speed and a desired engine torque, and determining a second power value as a function of turbine speed, driveline efficiency and a desired wheel power. The desired engine power is then selected as the lesser of the first and second power values. In another aspect of the invention, the first fuel flow value is modulated by a static and dynamic fault tolerance margin to prevent fuel limiting during normal engine operation.

    • A method and system are provided for distinguishing a cylinder identification (CID) signal pulse from camshaft timing signal pulses in a variable cam timing (VCT) engine having multiple engine combustion events. The method includes generating multiple signal pulses including a signal pulse which identifies an engine cylinder and a signal pulse for each one of the multiple engine combustion events. The method also includes measuring a first time period between a first signal pulse and a second signal pulse, measuring a second time period between the second signal pulse and a third signal pulse, and determining that the third signal pulse is the cylinder identification signal pulse if a product of the second time period and a scaling factor fails to exceed the first time period. A specially designed VCT/CID signal generator, and an appropriately programmed microprocessor are provided for performing the method.
