摘要： A system and method for predicting cylinder air charge in an internal combustion engine for a future cylinder event is provided. The pressure in an intake manifold is calculated and an estimated position for a throttle plate of the engine at least one cylinder event in the future is determined responsive to an electronic throttle control command. A rate of change of pressure in the intake manifold is then estimated responsive to the measured intake manifold pressure and the estimated throttle plate position. The cylinder air charge is then calculated responsive to the rate of change in pressure in the intake manifold.

摘要： A system and method for selecting one of first and second camshafts in an engine is provided. The first and second camshafts control air flow communicating with the first and second cylinders, respectively, of the engine. The engine includes a crankshaft being driven by first and second pistons with the first and second cylinders. The method includes determining which of the first and second camshafts is moving at a faster rate of movement toward a first scheduled phase angle with respect to the crankshaft. Finally, the method includes selecting one of the first and second camshafts having the faster rate of movement for reducing engine torque fluctuations.

摘要： A system and method for controlling first and second phase shiftable camshafts in a variable cam timing engine is provided. The method includes determining when the first camshaft is moving toward a first scheduled phase angle with respect to the crankshaft at a faster rate than the second camshaft is moving toward the first scheduled phase angle. Finally, the method includes slowing down the first camshaft so that the rate of movement of the first camshaft approaches a rate or movement of the second camshaft toward the first scheduled phase angle.

摘要： A method is provided for controlling an engine exhaust with an upstream sensor and a downstream sensor. The method comprises adjusting a set-point for the downstream sensor based on a rate of change of air mass flow upstream of the engine and adjusting fuel injection to control exhaust fuel-air ratio (FAR) at the downstream sensor to the adjusted set-point, and to control exhaust FAR at the upstream sensor to an upstream sensor set-point.

摘要： A method for estimating operating parameters of an internal combustion engine uses data stored as a function of intake and exhaust valve timing. In particular, the parameters are stored at a default operating point, several stability limited points, a high performance point, and an intermediate point. An inverse distance interpolation algorithm is used to calculated current slope and offset values at the current operating conditions. From these calculated slope and offset values, engine operating parameters, such as manifold pressure and cylinder air amount, are estimated.

摘要： An early cylinder identification method and system using pulsewidth encoding are provided for use in a variable camshaft timing equipped engine. The method includes generating multiple signal pulses, each signal pulse having a unique length and being associated with one of the engine cylinders. The method also includes measuring the length of a signal pulse, and identifying the engine cylinder associated with the signal pulse based on the measured length of the signal pulse. A system includes a specially designed sensor wheel and control logic for performing the method.

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.
