Differential pressure valve based boost device inlet pressure optimization
17 Aug 21
Techniques for controlling a forced-induction engine having a low pressure cooled exhaust gas recirculation (LPCEGR) system comprise determining a target boost device inlet pressure for each of one or more systems that could require a boost device inlet pressure change as part of their operation and boost device inlet pressure hardware limits for a set of components in the induction system, determining a final target boost device inlet pressure based on the determined sets of target boost device inlet pressures and boost device inlet pressure hardware limits, and controlling a differential pressure (dP) valve based on the final target boost device inlet pressure to balance (i) competing boost device inlet pressure targets of the one or more systems and (ii) the set of boost device inlet pressure hardware limits in order to optimize engine performance and prevent component damage.

Calibration techniques for forced-induction engines having low pressure cooled exhaust gas recirculation (LPCEGR) systems include commanding an EGR to a fully-closed position, after the EGR valve has reached the fully-closed position, commanding the engine to operate at fixed steady-state conditions for a calibration period, wherein the fixed steady-state conditions comprise at least a fixed throttle valve angle, a fixed injected fuel mass, and a fixed cylinder air/fuel ratio (AFR), during the calibration period, increasingly opening the EGR valve and monitoring a AFR of exhaust gas produced by the engine, calibrating an EGR fraction estimation and EGR transport delay model based on previously measured and/or modeled total engine flow and the monitored exhaust gas AFR during the calibration period, and storing the calibrated model at a memory of a controller of the engine for future usage to improve engine operation.
