Abstract:
An apparatus for the reduction of emissions from a liquid-cooled internal combustion engine having a cooling liquid circulation loop, comprising:a heat generator driven by the internal combustion engine and connected into said cooling liquid circulation loop to heat a liquid provided within the circulation loop so as to speed up an increase of a temperature of the internal combustion engine and thereby reduce the emissions therefrom;said heat generator includinga rotor having a shaft driven by the internal combustion engine, a disc of a soft magnetic material, and a plurality of permanent magnets said permanent magnets generating a magnetizing field of the rotor, fixedly connected to the disc and axially extending from said disc,a stator having a ring of electrically conductive material, wherein the ring is arranged along a periphery of the rotor such that the magnetizing field of the rotor passes through the stator and induces electric currents which generate heat in the stator ring, anda chamber extending along the periphery of the rotor, said chamber including an inlet and an outlet connecting the chamber into the circulation loop of the internal combustion engine, the stator being part of the chamber, and which permits circulation of the cooling liquid of the internal combustion engine between the inlet and the outlet for absorbing the heat which is generated in the stator ring, when the rotor is rotated.
