ABSTRACT:
An electric motor used to control the butterfly valve in an engine is supplied with increased dissipating energy. The mechanical link between the electric motor and the butterfly valve, preferably combined with favorable heat conductivity of the inlet pipe material in the area of the butterfly valve, facilitates transfer of the electric motor's dissipating heat to the butterfly valve nozzle.
