System and Method for Reducing The Amount of Polluting Contents in the Exhaust Gas of a Liquid Fueled Combustion Engine

An apparatus for the reducing the polluting content in the exhaust gas of a liquid fueled combustion engine, comprising a mixing system with at least a first and a second mixing area, wherein the output line of the last mixing area is connectable to a combustion system and each mixing area comprises

• an essentially rotationally symmetric mixing chamber,
• at least one inlet line for introduction of free-flowing components arranged upstream of or below the at least one outlet line,
• at least one conveying device per component or per component mixture,
• a turbulent mixing area on the inlet side, in which the components are mixed turbulently by the shear forces exerted by the stirrer units,
• a downstream percolating mixing area in which the components are mixed further and the turbulent flow decreases,
• a stirrer unit which ensures laminar flow and comprises stirrer elements secured on a stirrer shaft, the axis of rotation of which runs along the axis of symmetry of the chamber and the stirrer shaft of which is guided on at least one side,
• at least one drive for the stirrer unit,
• wherein
• the ratio between the distance between inlet and outlet lines and the diameter of the chamber is ≧2:1,
• the ratio between the distance between inlet and outlet lines and the length of the stirrer arms of the stirrer elements is 3:1 to 50:1,
• the ratio of the diameter of the stirrer shaft, based on the internal diameter of the chamber, is 0.25 to 0.75 times the internal diameter of the chamber,
• and wherein
• the first mixing area comprises
• at least two input lines
• a laminar mixing area on the outlet side, in which a lyotropic, liquid-crystalline phase is established in the mixture of the components, in the direction of the outlet line.
