Summary

Stringent pollution norms for both light and heavy duty vehicles have led to the development of new strategies and complex technologies. This has resulted in significantly higher functionality with regard to engine controls, thus increasing the amount application work. The emission legislation, which has already been passed for implementation in the near future, demands a further drastic reduction in tailpipe emission of diesel engines. The trend towards higher homogenisation, along with the increasing relevance of emissions, emitted during highly transient operation, require further development of control strategies. Minimizing both system hardware and development costs, will be possible in the future only with the establishment of physical-model based software structures and adaptive control strategies, that can substantially reduce the application effort regarding engine operation.
