Delphi Automotive Systems is entering the direct injection diesel business, which requires a significant shift in technologies from the current diesel injection approach. The injector itself is the key to mastering this goal and its high sensitivity to sources of variation makes robust engineering a valuable approach to optimization. This robust engineering case study shows that cost effective and informative robust engineering projects can be conducted using good simulation models, with hardware being used to confirm results. The case study also identified the need to extend the tolerance design method to dynamic response when a dynamic parameter design is used. The ability to consider manufacturing variation is an important advantage compared to full hardware based robust engineering. Hardware confirmation should be conducted to ascertain the results and should not lead to a surprise if a good robustness level is achieved up‐front on the simulation model.
