摘要： 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.

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 internal combustion engine having variable camshaft timing that incorporates a method of determining the position of the variable cam timing phasing system for controlling the flow of intake and exhaust gases during the combustion process. The method includes the steps of creating a model for estimating a calculated cam position and a calculated rate-of-change of the cam position. The method also includes the step of measuring a measured cam position and a measured rate-of-change of the cam position. The calculated cam position is compared to the measured cam position and calculated rate-of-change of the cam position and measured rate-of-change of the cam position that are blended based upon a comparison of the two values. The engine controller is adjusted dependent upon the blended rate-of-change of the cam position.

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.
