| 1. A method for performance-improving emission of exhaust gases from internal combustion engines in submarines into the water
surrounding the submarines, the method comprising:
mixing the exhaust gases and a water flow, taken from the water surrounding the submarines and produced in a pump device,
with one another in a reduced-pressure field, the reduced pressure of the reduced-pressure field being produced by a reduction
in the cross-sectional area of the water flow before mixing, the reduction in the cross-sectional area being carried out in
such a manner that an accelerated water flow in the form of a hollow cylinder is produced, and the hollow-cylindrical water
flow being caused to rotate.
