Adaptive Control of the Real-Driving Emissions of Diesel Engines

Abstract

The operating strategy for minimizing pollutant formation typically has to be frozen by manufacturers once an engine leaves production. Therefore, the raw emission characteristic of the engine cannot be changed anymore. At the ETH Zürich, we investigated the benefits of a variable operating strategy for the internal actuators of a diesel engine that could be used to adapt the raw emission formation characteristic according to the driving situation. A case study with a passenger car will demonstrate the benefits of the proposed methodology.
