Phlegmatisation of a Combustion Engine for Reduction of Particle Transient Emissions

For mobile machines, which are mainly using diesel engines as power source, dropping emissions are a decisive factor for coming emission standards. Researches have shown that particle and NOx emissions are extremely high especially during transient operating states. Within this transient operating states the turbocharger of the combustion engine is not able to fill enough air in the combustion chamber, which causes high particle and NOx emissions. These transient operating states occur repeatedly at working cycles of mobile machines, for example, in the case of transporting and stacking straw bales with a telehandler. Due to a great potential for recuperation of kinetic and potential energy in repetitive working cycles of mobile machines, this energy could be used in powertrain concepts with a hybrid module to reduce the engine-out emissions by phlegmatisation of the combustion engine.
