    Abstract: An exhaust gas recirculation (EGR) valve is positioned within an EGR passage fluidly connecting an engine exhaust stream and an engine intake stream, while a waste heat recovery (WHR) system is used to recover heat from the EGR stream. An engine control unit (ECU) is coupled to various sensors and valves to divert working fluid in the WHR system from cooling the EGR exhaust flow below a level which favors production of condensation in the engine intake system. The ECU operates a three-way valveto divert working fluid flow away from the EGR boiler when sensors indicate characteristics of either the exhaust flow or the intake stream which might lead to heavy condensation.

    Abstract: An internal combustion engine (10) has a control system (24) for processing various data to develop data for control of various aspects of engine operation, including controlling a device, such as an EGR valve (22) or turbocharger (16). A transient compensation strategy develops a multiplier data value for transient compensation of a control data value for controlling the device by multiplying that control data value by that multiplier data value. The transient compensation strategy comprises a map (34, 40) containing data values for the multiplier, each of which is correlated with both a particular data value for engine speed within a range of data values for engine speed (N) and a particular data value for accelerator pedal rate (APS d) within a range of data values for accelerator pedal rate. The strategy selects one of the multiplier data values from the map on the basis of a data value for engine speed and of a data value for accelerator pedal rate and then multiplies the control data value for controlling the device by the one selected multiplier data value.
