Phlegmatization of a Combustion Engine for Reduction of Transient Emissions

The main topic of this paper is the reduction of transient engine-out emissions ejected by diesel engines through phlegmatization. This phlegmatization is supported by a hydraulic hybrid module to prevent system dynamics from dropping. In order to design the hybrid module according to its size and an optimal reduction of transient engine-out emissions, a design tool will be developed. In addition, the structure of a simulation model is presented, which serves to test different hybrid module concepts and creates the data basis for the design tool.
