Comparison of Engine Calibration Methods Based on Design of Experiments (DoE)

Abstract : Due to more stringent emission and durability requirements as well as higher client-felt quality targets, engine technology and strategies used to control them are more and more complex. Car manufacturers need productive and reliable test facility as well as efficient methods and tools to address the challenge of tuning the increasing number of parameters related to these strategies, while reducing in the same development schedule and cost. In this context, IFP is developing methods to perform engine calibration, using a full automated test bench together with advanced mathematical methods for modeling and optimizing, as well as engine and vehicle simulation. The paper describes and compares the different approaches to perform the mapping of an engine on the NEDC area. Results obtained on a Common Rail Diesel engine are also presented to illustrate specific development works.
