Virtual Engine Calibration: Making Engine Calibration Part of the Engine Hardware Design Process

Engine base calibration is traditionally performed well after an engine hardware design is established using CAE models. However, base calibration significantly affects engine performance. As such, engine designers cannot objectively judge the performance impact of hardware design changes during the engine hardware design phase. MathWorks developed a Virtual Engine Calibration Optimization (VECO) process to enable SI engine designers to automatically generate an optimal base engine calibration directly and automatically from their CAE models. The process also provides a starting-point calibration for production engine calibration development in the engine dynamometer laboratory after engine prototype hardware is built based on the CAE model design.
