Developing and Deploying Optimization Strategy for Engine Calibrations

Diesel engine calibration is a careful balance of emissions while trying to achieve the lowest fuel consumption possible. In a certain instance of trying to achieve this balance, some areas of the calibration yielded enough smoke to cause EGR cooler fouling issues under the right conditions.

This presentation discusses this challenge for Cummins and how the optimization process and MATLAB^® based toolkit was used to improve robustness to smoke while maintaining the rest of the emissions constraints. The Cummins-developed toolkit utilizes many MATLAB toolboxes including Statistics and Machine Learning Toolbox™, Parallel Computing Toolbox™, Optimization Toolbox, and MATLAB Compiler™.
