Claim Text:
1. A combustion engine comprising a device for cleaning of polluted gas within the combustion engine, the combustion engine comprising: a space formed entirely within the combustion engine, the space formed entirely within the combustion engine having polluted gas therein and the space formed entirely within the combustion engine: the device comprising: a centrifugal separator for cleaning of the polluted gas, the polluted gas having suspended pollutants in the form of solid or liquid particles therein, the centrifugal separator comprising: a centrifuge rotor which is rotatable about a rotational axis by a drive device and is arranged to cause the polluted gas to rotate, wherein the centrifuge rotor comprises a stack of truncated conical separating discs disposed at mutual spacing so that adjacent pairs of the truncated conical separating discs delimit intermediate spaces therebetween for the polluted gas to flow through, wherein the centrifuge rotor extends into the space formed entirely within the combustion engine along the rotational axis, an outlet chamber which is disposed centrally within the stack of truncated conical separating discs and communicates with said intermediate spaces, whereby the centrifuge rotor is configured for counterflow separation in such a way that the polluted gas is caused to rotate and is led into the intermediate spaces radially from outside the stack of truncated conical separating discs and radially inwardly towards the outlet chamber, and a gas outlet which communicates with the outlet chamber and is arranged to conduct cleaned gas from the centrifuge rotor, the stack of truncated conical separating discs on the centrifuge rotor is disposed for rotation entirely in the space formed entirely within the combustion engine and arranged to receive the polluted gas, the intermediate spaces communicating directly with the space formed entirely within the combustion engine, and the gas outlet is arranged to conduct the cleaned gas out of the space formed entirely within the combustion engine through the at least one internal wall; and an unimpeded flow path extending radially outward from the stack of truncated conical separating discs directly to the space formed entirely within the combustion engine in the location in which the polluted gas resides, the stack of truncated conical separating discs being configured to separate the suspended pollutants from the polluted gas, to move the suspended pollutants radially outward along the stack of truncated conical separating discs and to propel the suspended pollutants radially outward from an edge of the stack of truncated conical separating discs through the unimpeded flow path and directly into the space formed entirely within the combustion engine in the location in which the polluted gas resides.
