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.
