A gasoline engine is an energy conversion device, where chemical energy is converted into mechanical energy.  Many technologies aim to decrease the net indicated fuel consumption (eg. downsizing, Atkinson/Miller cycles, lean/dilute operation, optimal design, etc.) By optimizing cam timing over a speed-load map, subject to constraints, further efficiency improvements can be gained.  This is accomplished using GT-Power to model the engine plant and controls and modeFRONTIER/SOMO to drive the process automation and optimization.  This presentation covers different DOE/Optimization strategies used to effectively optimize an engine’s operation over the speed-load map.
