With the Stage V Emission regulation of the European Union (EU) a new limit for the particulate emission including particulate number is introduced for diesel engines from 19 to 56 kW. Thereby new control strategies regarding particulates are required in this engine category. This article describes the DEUTZ engine platform concept for the engine category from 19 to 56 kW with a diesel particulate filter (DPF) as a standard technology to fulfill the EU Stage V emission regulation.

    The technical requirements of engines for non-road mobile machinery are described as well as the derived hardware concept of the engine family including the exhaust aftertreatment system. The introduction of a new ECU platform is used by DEUTZ for a new software concept with an airpath model based on a combination of physical engine models and data based numerical models to ensure the best performance and robustness under all ambient conditions. Furthermore, DEUTZ developed a new engine emission model including a DoE tool to reduce the calibration effort and improve the DPF model quality at the same time. The article also gives an insight on development methodology with an outlook on the virtual calibration using the DEUTZ offline simulation tool “xQtec”.
