CONTROLLING A VARIABLE GEOMETRY TURBOCHARGER AND AN INTAKE THROTTLE VALVE TO OPTIMIZE EXHAUST GAS TEMPERATURE AND COMPRESSOR OUTLET PRESSURE OF AN ENGINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17933570 titled 'CONTROLLING A VARIABLE GEOMETRY TURBOCHARGER AND AN INTAKE THROTTLE VALVE TO OPTIMIZE EXHAUST GAS TEMPERATURE AND COMPRESSOR OUTLET PRESSURE OF AN ENGINE
Simplified Explanation
The abstract describes a patent application for a controller that can optimize the settings of a variable geometry turbocharger (VGT) and an intake throttle valve (ITV) of an engine based on predicted values of compressor outlet pressure and exhaust gas temperature.
- The controller identifies potential parameters for the VGT and ITV settings.
- It determines predicted values for compressor outlet pressure and exhaust gas temperature.
- The controller assigns scores to the predicted values and selects the best set of values.
- The controller then adjusts the VGT and ITV settings accordingly.

Original Abstract Submitted
A controller may identify a plurality of sets of potential parameters associated with operation of an engine, wherein each set of potential parameters includes a potential setting of a turbine of a variable geometry turbocharger (VGT) of the engine and a potential setting of an intake throttle valve (ITV) of the engine. The controller may determine, based on the plurality of sets of potential parameters, a plurality of sets of predicted values, wherein each set of predicted values includes a predicted outlet pressure of a compressor of the VGT and a predicted temperature of an exhaust gas of the engine. The controller may determine respective scores of the plurality of sets of predicted values, and may select, based on the respective scores, a particular set of predicted values of the plurality of sets of predicted values. The controller may thereby control the turbine of the VGT and the ITV.
