Modern heavy-duty powertrains must meet statutory emission standards while ensuring the lowest possible running costs to keep ahead in the face of tough competition. This demands ideal interaction between the engine and the exhaust-gas aftertreatment system as an overall unit.
In addition to calibrating metering strategies for SCR systems or load control systems for particulate filters, we also provide smart exhaust-gas temperature management systems and optimized regeneration strategies for developing highly efficient overall systems. We conduct the standardized emission cycles for homologation (U.S., EU and Japan) on our engine dynamometers that benefit from state-of-the-art exhaust emission measurement equipment.
We use a variety of simulation tools for optimizing calibration. For instance, we can predict the efficiency of exhaust-gas aftertreatment systems at early stages in the development process and use this as the basis for optimizing the way components interact. This minimizes the number of iterations required and ensures cost efficiency for the client. Besides addressing the overall system we can also analyze details, such as ammonia distribution in the SCR catalyst, and verify these in special
