Introduction
Thanks to their high performance, Selective Catalytic Reduction (SCR) systems are commonly used to reduce NOx emissions from diesel engines. The high performance of these systems is ensured by complex control strategies embedded in the engine’s control unit. Nevertheless, production tolerance or ageing of the SCR system’s components may affect the high level of NOx conversion efficiency. Special adaptive logics are applied to guarantee long term performance and robustness of the SCR system and simulation tools are used to evaluate the capabilities of these algorithms.
Role description
The job holder will integrate the SCR system development team, get introduced to the SCR system, controls and simulation tools and support the development of SCR control algorithms by:
- Running engine dyno and vehicle tests to collect real engine data.
- Building and maintaining a Matlab simulation platform combining a physical model of the SCR catalyst model and the embedded SCR controller.
- Running simulations by applying tolerances and drifts on different driving patterns including real driving profiles.
- Providing a deep analysis of the simulation results, comparing to engine dyno or vehicle data and presenting the conclusions to the SCR team.
