Validation of Aftertreatment Temperature Requirements Using MathWorks Tools

Travis Barnes, Caterpillar Inc.

Engine aftertreatment temperature is critical for proper operation to meet increasingly stringent emission regulations. Acceptable aftertreatment temperatures and regeneration operation need to be verified for the numerous applications seen in heavy-duty construction, industrial, and mining applications. The development of models using MATLAB® and Simulink® has allowed significant cost reductions by eliminating cycle tests in test cell and replacing them with simulation. The robustness of the system was evaluated using validated models to assure proper system performance with expected component variability.
