  • Internal combustion engine
    Patent number: 8720402
    Abstract: An internal combustion engine having a plurality of cylinders and an air intake system, with the air intake system formed from at least one distributor pipe, a plurality of intake pipes and at least one plenum, and with the plenum positioned between the distributor pipe and the intake pipes. Here, the combustion air is fed to the air intake system via an air guiding duct which opens out into the distributor pipe, with the charge pressure of the combustion air reduced between the outlet out of the compressor and the inlet into the combustion chamber. A distributor pipe length is dimensioned as a function of an equivalent distributor pipe diameter such that it is possible for a reduction in the charge pressure to be obtained within the air intake system by expansion taking place partially in the plenum in the respective intake pipe and/or within the distributor pipe.
