Calibration engineers are currently facing numerous new challenges arising from increasingly stringent legal requirements.

With the introduction of emission regulations like EURO VI, EPA10, Stage IV and Tier4 a “Not-To-Exceed (NTE)” zone has been introduced, where tail pipe emissions must not exceed a specified value. They must be measured stationary in the WNTE (World harmonized Not-To-Exceed) area combined with specific ambient conditions.

For the engineer, this means that he needs to find a calibration that assures meeting emission requirements at various ambient conditions while still delivering the desired engine performance and fuel consumption. In this process, he is facing two major challenges:

1. Finding the optimal compromise between emission, performance and fuel consumption targets under all ambient conditions.
2. Achieving this with very limited access to non-standard engine tests beds.

AVL suggests to pre-calibrate these engine correction functions on an AVL Virtual Testbed™, a hardware-in-the-loop test bed, with AVL CRUISE™ M MOBEO models. This delivers an identical environment as on real testbeds, while saving time and money.
