A variable nozzle turbocharger ( ) creates engine boost. Boost is controlled by controlling the position of vanes within turbocharger. A processor develops a control signal ( ) for controlling vane position. The processor develops a value for desired boost and processes that value with a value. corresponding to the amount of boost being created by the turbocharger to generate error data ( A) defining error between the amount of boost being created by the turbocharger and the desired boost, and the processor develops a component of the control signal by P-LI-D processing ( ) of the error data. Other components of the control signal are a feed-forward value from a look-up table ( ) and a value from an overspeed protection function ( ).

Engine speed data N and engine fueling data MFDES are processed by a strategy ( ) that multiplies ( ) fueling transient data MFDES TRANSIENT and speed-based modifier data EGR_N_TRANS_MULT to develop speed-based fueling transient data. The speed-based fueling transient data is then processed according to a function ( ) that correlates values of a fueling transient modifier with values of speed-based fueling transient data to develop exhaust gas recirculation modifier data. The exhaust gas recirculation modifier data and basic exhaust gas recirculation data are multiplied ( ) to develop modified exhaust gas recirculation data, and exhaust gas is recirculated in accordance with the modified exhaust gas recirculation data. Using engine speed as a determinant of the extent to which the basic EGR rate should be modified during a fueling transient enables better control over certain exhaust emissions over certain speed ranges.

Testing of temperature sensors () in an emission control system, such as in an exhaust system () of a diesel engine, serves to condition further component and/or system testing by determining that sufficient sensor cooling has occurred and that no sensor is “stuck within range” using a strategy ().

A control system for operating vanes of a turbocharger turbine (T) and for operating a turbine-shunting bypass valve () according to a strategy wherein a processor executes an algorithm for selectively unenabling the control system to operate the bypass valve when the control system is operating the vanes to adjust exhaust back-pressure on the engine within a range of effectiveness for the vanes to control the exhaust back-pressure and enabling the control system to operate the bypass valve when the control system has operated the mechanism to a limit of the range of effectiveness.

An engine control system () apportions smoke and NOx in engine-out exhaust gas by a strategy () that corrects a target percentage for fresh air and a target percentage for exhaust gas to recalculate a set-point for fresh air mass flow. The target percentage for fresh air mass flow is calculated as a function of engine speed (N) and an engine output torque request (TQI_DRIV).

A method of operating an engine is provided. Output of an engine speed sensor, a mass air flow sensor, an exhaust gas temperature sensor, and an engine torque estimator are monitored with an electronic control module. It is determined if the engine is operating in one of either a transient condition and a non-transient condition based upon output of at least one of the sensors and the torque estimator. Fuel injection timing is set based upon if the engine is operating in a transient condition. An exhaust gas recirculation valve position is set upon if the engine is operating in a transient condition. An intake throttle position is set based upon if the engine is operating in a transient condition. The fuel injection timing, exhaust gas recirculation valve position, and the intake throttle position are set to minimize NOx emissions when the engine is operating in a transient condition.

A method of controlling a variable geometry turbocharger is provided. A predefined desired boost pressure of a turbocharger is obtained from a memory. A predefined desired mass flow rate in an intake manifold of an engine is obtained from the memory. A theoretical amount of power required by the turbocharger to generate the desired boost pressure and the desired mass flow rate is calculated. An actual mass flow rate in the intake manifold is determined. An actual amount of power required by the turbocharger to generate the desired boost pressure and the actual mass flow rate is calculated. At least one adjustable vane of the turbine of the turbocharger is adjusted to allow the theoretical amount of power required of the turbocharger to generally equal the actual amount of power by adjusting the boost pressure.

A method of controlling operation of an engine is provided that utilizes a number of preset operating parameters. The method determines an operating mode of the engine. The method determines an operating state of the engine. A plurality of engine parameter settings is retrieved from a memory in response to the determined operating mode and the determined operating state of the engine. The plurality of engine parameter settings are applied to at least one control algorithm of the engine.
