Non-Standard Condition Calibration for Commercial Vehicles
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:
- Finding the optimal compromise between emission, performance and fuel consumption targets under all ambient conditions.
- 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.
