Patent ID: 8746216

Claim:
An internal combustion engine, comprising: a piston engine having at least one combustion chamber, a fresh air system for feeding fresh air to the at least one combustion chamber including at least one fresh air line, a bloom mixer arranged in the fresh air line and configured to divide a fresh air flow conducted in the fresh air line into at least two partial flows and reunite these again on an out-flow side subject to the formation of a turbulence, wherein the bloom mixer comprises a sheet-metal body having an on-flow side and an out-flow side with a bloom structure and which divides the fresh air line from an on-flow edge of the sheet-metal body to an out-flow edge of the sheet-metal body into two line portions configured to be subjected to parallel through-flow, an infeed point connected to the fresh air line via a recirculation line of an exhaust gas recirculation system and arranged in at least one of a region upstream of the bloom mixer and in the bloom mixer for recirculating exhaust gas into the fresh air, wherein the infeed point is positioned relative to the bloom mixer so that the recirculated exhaust gas only flows into one of the line portions, and a flow guiding element arranged in the fresh air line upstream of the infeed point and which is adjustable in order to more or less obstruct the inflow of fresh air to one of the line portions dependent on its position.
