摘要： A system is provided for estimating an operational parameter of a first engine, the first engine including a rotatable crankshaft. The system includes a model for estimating the operational parameter of the first engine as a function of instantaneous crankshaft speed at a plurality of angular positions of the crankshaft of the first engine. The model is developed, at least partially, based upon operational data from a second engine having a rotatable crankshaft. A sensor is operable to determine values representative of the instantaneous crankshaft speed of the first engine, at a plurality of angular positions of the crankshaft of the first engine. A modifier is operable to modify at least some of the representative values to, at least partially, calibrate out differences between the first and second engines that may cause variations in instantaneous crankshaft speed. The modified values are input to the model.

摘要： A method and system may be provided to perform a process for controlling NOx emissions of an target engine. In one embodiment of the invention, the process may include determining predicted NOx values based on a model reflecting a predetermined relationship between control parameters and NOx emissions, wherein the control parameters include ambient humidity, manifold pressure, manifold temperature, fuel rate, and engine speed associated with the engine. Further, the process may include adjusting the model based on a determination of whether the predicted NOx values meet a predetermined criteria associated with actual NOx values. The adjusted model may be stored in a memory associated with the engine whereby NOx emissions exhausted from the engine may be reduced based on virtual NOx emission values determined from the adjusted model.

摘要： A method and apparatus for real-time measurement of combustion characteristics of each combustion event in each individual cylinder coupled with an ability to control the engine based upon the combustion characteristics are shown. The invention includes using selective sampling techniques and wavelet transforms to extract a critical signal feature from an ionization signal that is generated by an in-cylinder ion sensor, and then feeds that critical signal feature into an artificial neural network to determine a desired combustion characteristic of the combustion event. The desired combustion characteristic of the combustion event includes a location of peak pressure, an air/fuel ratio, or a percentage of mass-fraction burned, among others. The control system of the engine is then operable to control the engine based upon the combustion characteristic.

摘要： A powertrain controller of a vehicle provides fuel injection pulses based on gasoline operation. The pulse widths of the fuel injection pulses are modified with reference to air temperature, engine speed, and exhaust gas oxygen (EGO) content to control fuel injectors for an alternative fuel such as natural gas. The EGO content, based on alternative fuel operation, is detected and compared to a desired air-fuel ratio or desired fuel trims to provide error information that is used to adjust the modification of the pulse widths. In response to the error information, a neural network (as an example) dynamically adjust the pulse widths of the alternative fuel injection based on the weights of measured, detected engine speed, EGO, universal exhaust gas oxygen, or air temperatures. The engine operating on alternative fuel is provided with the proper mixture of alternative fuel and air to respond to various engine loads and meet emission standards.

The pressure in the distributor pressure space, which is assigned jointly to the engine combustion chambers, of the common-rail fuel injection system is detected for a respective fuel injection operation for a respective combustion chamber in its signal course via a pressure sensor of the distributor pressure space. From the detected pressure course, a pertaining pressure course pattern is obtained from which the at least one fuel-injection-related parameter is determined individually for each combustion space and each injection operation.
