Heavy-duty approval test cycles: assessment of currently applied test cycles and theories for the development of new duty cycles
conference paper
In the development of the new emission reduction technologies, the benefits of the use of these technologies must be assessed for real-life engine use. As in practice engines are developed to perform as good as possible on the approval test cycle on the basis of which emission limits are set, it is of the utmost importance that the engine load during these approval test cycles closely represents real-life engine load. This paper highlights the assessment of the representativity of the current and near-future approval test cycles. Also theories for the development of new duty cycles are presented.
