| Description: |
Reducing transient emissions from internal combustion engines in mobile working machines presents a significant challenge, especially in terms of complying with strict environmental regulations. A prom-ising method for reducing these emissions is the phlegmatization, where the internal combustion en-gine is delayed in adjusting to the new load level after a load step. This allows the air path more time, resulting in lower NOx and PM emissions. This paper presents the concept of a hybrid module used for phlegmatization and its approach for an operating strategy. Additionally, the simulation model built to investigate the concept is introduced, with a specific focus on parameterizing and verifying the engine models of two diesel engines. Further-more, the map area with the highest savings potential for both engines is determined. Finally, the approach for an operating strategy of the hybrid module is outlined. |
